Cardiovascular Review Questions and Answers

What is the most common adverse effect of ACE inhibitors?

Answer: A dry, persistent cough.

ACE inhibitors such as lisinopril can cause a persistent, nonproductive cough. This effect is associated with increased levels of bradykinin and other mediators. If the cough becomes troublesome, the healthcare provider may consider changing the medication, often to an angiotensin II receptor blocker (ARB).

What should a patient taking spironolactone know about potassium?

Answer: Potassium supplements may need to be avoided unless specifically prescribed.

Spironolactone is a potassium-sparing diuretic that can increase serum potassium levels. The risk of hyperkalemia is greater in people with impaired kidney function or those taking other medications that raise potassium levels. Patients should not routinely use potassium supplements or potassium-containing salt substitutes unless directed by their healthcare professional.

What should a pregnant patient taking an ACE inhibitor do?

Answer: Contact the healthcare provider promptly.

ACE inhibitors can cause serious fetal complications and are generally avoided during pregnancy. Potential risks include fetal renal dysfunction, oligohydramnios, fetal skull abnormalities, and neonatal complications. A patient who becomes pregnant while taking an ACE inhibitor should contact the prescriber so treatment can be reassessed.

Why may metoprolol be combined with nifedipine?

Answer: To help reduce reflex tachycardia.

Nifedipine is a dihydropyridine calcium channel blocker that can cause reflex increases in heart rate. Metoprolol, a beta blocker, can help control this response while also reducing myocardial oxygen demand and heart rate.

What teaching helps reduce orthostatic hypotension caused by vasodilators?

Answer: Change positions slowly and avoid standing suddenly.

Vasodilating medications can lower blood pressure and cause dizziness or orthostatic hypotension. Patients should move slowly when changing from lying to sitting or from sitting to standing. This simple precaution can reduce the risk of falls and injury.

What lifestyle measures can help prevent or manage hypertension?

Answer: Reduce sodium intake, maintain a healthy weight, exercise regularly, moderate alcohol intake, and avoid tobacco.

Lifestyle factors can significantly influence blood pressure. A heart-healthy dietary pattern such as the DASH diet, regular physical activity, weight management, and tobacco avoidance can support blood pressure control. Family history also contributes to hypertension risk.

Which medications can improve outcomes after myocardial infarction?

Answer: ACE inhibitors and beta blockers are commonly used when clinically appropriate.

Evidence-based medications following myocardial infarction can reduce cardiovascular complications and mortality in appropriate patients. Treatment depends on factors such as ventricular function, blood pressure, kidney function, comorbidities, and the patient’s overall clinical condition.

Which two antiarrhythmic drug classes can have similar cardiac effects?

Answer: Beta blockers and nondihydropyridine calcium channel blockers.

Beta blockers and calcium channel blockers such as verapamil and diltiazem can slow heart rate and atrioventricular-node conduction. They may also decrease myocardial contractility, although their effects and indications differ among individual medications.

What symptom is concerning in a patient taking simvastatin who is prescribed azithromycin?

Answer: New muscle pain, tenderness, or weakness.

Muscle symptoms in a patient taking a statin should be assessed because they may indicate statin-associated muscle injury. Severe muscle injury can progress to rhabdomyolysis and acute kidney injury. Potential drug interactions should also be reviewed whenever new medications are added.

What treatment may be used for significant warfarin-associated bleeding?

Answer: Vitamin K with additional reversal therapy when indicated.

Management of excessive warfarin anticoagulation depends on the INR, severity of bleeding, bleeding location, and clinical circumstances. Serious or life-threatening bleeding may require intravenous vitamin K along with a rapid-acting factor replacement product such as four-factor prothrombin complex concentrate (PCC).

Endocrine Review Questions and Answers

What short-term complications should be assessed in a newly diagnosed patient with diabetes?

Answer: Hyperglycemia, hypoglycemia, and diabetic ketoacidosis (DKA).

Acute glucose-related complications can develop quickly and require prompt recognition. Chronic complications such as neuropathy, vascular disease, and kidney disease generally develop over a longer period.

Which insulin is appropriate for rapid correction of premeal hyperglycemia?

Answer: A rapid-acting insulin such as insulin lispro.

Rapid-acting insulin analogs include lispro, aspart, and glulisine. They have a relatively quick onset and short duration and are commonly used around mealtimes according to the patient’s prescribed insulin plan.

What dietary strategy is important for patients with type 1 diabetes?

Answer: Carbohydrate counting.

Carbohydrate counting helps patients coordinate food intake with insulin administration. Nutrition plans should be individualized according to the person’s insulin regimen, activity level, glucose targets, nutritional needs, and overall health.

Which laboratory test estimates average blood glucose over approximately three months?

Answer: Hemoglobin A1C (HbA1c).

HbA1c provides an estimate of average blood glucose exposure over approximately the previous two to three months. Conditions that affect red blood cell survival can influence the accuracy of the result.

How is insulin glargine generally administered?

Answer: Once daily at a consistent time according to the prescribed regimen.

Insulin glargine is a long-acting basal insulin designed to provide relatively consistent glucose-lowering activity. It is not intended to function as a rapid mealtime insulin.

What medication may be used as part of treatment for thyroid storm?

Answer: Propylthiouracil (PTU) may be used as part of the treatment regimen.

Thyroid storm is a medical emergency involving severe thyrotoxicosis. Treatment typically requires several interventions, including a thionamide, beta blockade when appropriate, corticosteroids, supportive care, and management of the underlying trigger.

Which findings suggest hypothyroidism?

Answer: Bradycardia, cold intolerance, fatigue, and low body temperature are characteristic findings.

Hypothyroidism slows many metabolic processes. Common findings can include fatigue, cold intolerance, weight changes, dry skin, constipation, and a reduced heart rate.

Why should hypothyroidism be treated during pregnancy?

Answer: Adequate maternal thyroid hormone is important for fetal development.

Maternal thyroid hormone is important for fetal brain and physical development. Untreated hypothyroidism can adversely affect pregnancy and fetal outcomes. Levothyroxine is the standard thyroid hormone replacement medication and is used during pregnancy when clinically indicated.

How does radioactive iodine treat Graves disease?

Answer: It is taken up by thyroid tissue and destroys thyroid cells, reducing thyroid hormone production.

Radioactive iodine is an established treatment for Graves disease and other causes of hyperthyroidism. Patients receive individualized radiation-safety instructions. Treatment frequently results in hypothyroidism over time, which can then be managed with thyroid hormone replacement.

Respiratory Review Questions and Answers

How do H1 antihistamines work?

Answer: They block H1 histamine receptors and reduce histamine-related symptoms.

H1 antihistamines work by blocking histamine activity at H1 receptors rather than primarily preventing histamine release. First-generation antihistamines are more likely to cause sedation because they readily cross the blood-brain barrier, whereas many second-generation agents are less sedating.

What should a patient taking hydroxyzine know?

Answer: Avoid alcohol and other central nervous system depressants unless specifically approved by the healthcare provider.

Hydroxyzine is a sedating first-generation antihistamine. Combining it with alcohol, opioids, sedatives, or other central nervous system depressants can increase drowsiness and impairment.

What is important when using a metered-dose inhaler?

Answer: Use correct inhaler technique and follow the prescribed timing between puffs.

Patients should coordinate inhaler activation with inhalation and follow the instructions specific to their device. A spacer can improve medication delivery for many people using a pressurized metered-dose inhaler.

How should long-acting beta2 agonists be used in asthma?

Answer: LABAs should be used as part of an ICS-containing treatment regimen rather than as asthma monotherapy.

Long-acting beta2 agonists provide prolonged bronchodilation but do not adequately treat the underlying airway inflammation associated with asthma. Current asthma management emphasizes inhaled corticosteroid-containing treatment.

Which medication provides rapid bronchodilation?

Answer: An inhaled short-acting bronchodilator can provide rapid symptom relief when appropriate.

Short-acting beta2 agonists such as albuterol have traditionally been used as rescue medications. However, contemporary asthma guidelines increasingly emphasize inhaled corticosteroid-containing reliever approaches for appropriate patients.

What is the role of inhaled corticosteroids in asthma?

Answer: They reduce airway inflammation and help prevent asthma exacerbations.

Inhaled corticosteroids are controller medications rather than immediate rescue treatments. Patients should understand which medication is intended for long-term control and which is intended for symptom relief.

What is the purpose of guaifenesin?

Answer: It is an expectorant that helps loosen respiratory mucus.

Guaifenesin increases the amount of respiratory secretions and may make mucus easier to cough up. It is intended to support productive coughing rather than suppress the cough reflex.

When are oral antihistamines useful for seasonal allergies?

Answer: They are generally most useful when taken consistently according to the medication directions during allergen exposure.

Second-generation antihistamines are commonly preferred for allergic rhinitis because they generally produce less sedation than first-generation medications.

Which bronchodilator is commonly preferred for stable COPD maintenance?

Answer: Long-acting inhaled bronchodilators are generally preferred for maintenance treatment.

COPD maintenance treatment may involve a long-acting beta2 agonist (LABA), long-acting muscarinic antagonist (LAMA), or combination therapy. Medication selection depends on symptoms, exacerbation history, and individual patient factors.

Neurologic and Musculoskeletal Review Questions and Answers

Why is epinephrine the medication of choice for anaphylaxis?

Answer: Epinephrine counteracts several life-threatening effects of anaphylaxis through alpha- and beta-adrenergic activity.

Intramuscular epinephrine is the first-line treatment for anaphylaxis. Its effects include vasoconstriction, improved blood pressure, reduced airway swelling, bronchodilation, and support of cardiovascular function.

How should the first dose of an alpha-adrenergic antagonist be administered?

Answer: The first dose is often taken at bedtime.

Alpha-adrenergic antagonists can produce a significant first-dose effect, including orthostatic hypotension, dizziness, and fainting. Taking the first dose at bedtime may reduce the risk of injury associated with these effects.

What may cause dyskinesias in a patient taking levodopa/carbidopa?

Answer: Levodopa-related dyskinesias can develop during treatment.

Involuntary movements can occur as a complication of long-term Parkinson disease treatment with levodopa. If dyskinesias become troublesome, the prescriber may adjust the dose, timing, or medication regimen.

What are important risk factors for Alzheimer disease?

Answer: Advancing age and family history are important risk factors.

Age is a major risk factor for Alzheimer disease, and genetic factors can influence susceptibility. However, having a family history does not mean that an individual will definitely develop the disease.

What should a patient taking phenytoin know about oral contraceptives?

Answer: Phenytoin can reduce the effectiveness of hormonal contraceptives.

Phenytoin is an enzyme-inducing antiseizure medication that can increase the metabolism of certain hormonal contraceptives. Patients should discuss reliable contraceptive options with their healthcare provider.

What laboratory monitoring may be necessary for certain antiseizure medications?

Answer: Serum drug concentrations may be monitored when therapeutic drug monitoring is clinically appropriate.

Some antiseizure medications have established therapeutic ranges. Drug levels can help assess adherence, toxicity, drug interactions, and whether medication concentrations are within an expected range.

When should aspirin generally be discontinued before surgery?

Answer: The timing depends on the indication for aspirin, bleeding risk, and type of surgery.

Aspirin irreversibly inhibits platelet function, so its effects can persist for the lifespan of affected platelets. Patients should not stop prescribed aspirin independently, especially when it is being used for cardiovascular protection. The surgical and prescribing teams should determine whether and when aspirin should be held.

How can long-term glucocorticoid therapy affect bone health?

Answer: Long-term glucocorticoid therapy increases the risk of osteoporosis and fractures.

Glucocorticoids can reduce bone formation, decrease calcium absorption, and increase bone resorption. Depending on individual risk, patients may require nutritional optimization, exercise and fall-prevention strategies, fracture-risk assessment, and osteoporosis medication.

Why is methotrexate started early in rheumatoid arthritis?

Answer: Methotrexate is a disease-modifying antirheumatic drug that can slow disease progression and prevent joint damage.

NSAIDs and glucocorticoids can help relieve pain and inflammation, but they do not provide the same disease-modifying effects as DMARDs. Early treatment can help reduce progressive joint damage in rheumatoid arthritis.

What treatment is considered for recurrent gout?

Answer: Urate-lowering therapy may be appropriate for patients with recurrent or clinically significant gout.

Allopurinol and febuxostat are examples of medications used to lower serum urate levels. Acute gout attacks are managed differently and may involve NSAIDs, colchicine, or corticosteroids.

Hormonal, Gastrointestinal, and Genitourinary Review Questions

What are the primary benefits of menopausal hormone therapy?

Answer: Hormone therapy can effectively treat menopausal vasomotor symptoms and help prevent bone loss in appropriate patients.

Hormone therapy should be individualized according to age, time since menopause, symptoms, medical history, risks, and treatment goals. Patients who have a uterus generally need a progestogen with systemic estrogen to reduce the risk of endometrial hyperplasia and cancer.

Who may need estrogen alone rather than combined estrogen-progestogen therapy?

Answer: A patient who has had a hysterectomy may generally use estrogen-only systemic therapy when hormone therapy is otherwise appropriate.

When the uterus is present, systemic estrogen is generally combined with a progestogen to protect the endometrium. After hysterectomy, progestogen is often unnecessary unless there is another clinical indication.

What is the treatment goal of terazosin in BPH?

Answer: To improve lower urinary tract symptoms and urinary flow.

Terazosin is an alpha-1 adrenergic antagonist that relaxes smooth muscle in the prostate and bladder neck. This can improve symptoms such as urinary hesitancy and difficulty initiating or maintaining urine flow. It does not primarily shrink the prostate.

What teaching is essential when metronidazole is prescribed?

Answer: Follow medication-specific guidance regarding alcohol avoidance during treatment and after the final dose.

Patients taking metronidazole should review current prescribing information and follow their healthcare provider’s instructions concerning alcohol. The medication can also cause gastrointestinal adverse effects and a metallic taste.

How should bulk-forming laxatives be taken?

Answer: They should be taken with adequate fluid.

Bulk-forming laxatives such as psyllium absorb water and increase stool bulk. Adequate fluid intake helps these medications work effectively and reduces the risk of obstruction.

Why should loperamide generally be avoided in certain infectious diarrheas?

Answer: Slowing intestinal movement can potentially delay pathogen elimination and increase complications in some infections.

Patients with bloody diarrhea, high fever, severe abdominal symptoms, or suspected invasive infection should seek medical evaluation rather than relying on antimotility medication.

What is an important interaction between TMP-SMX and glipizide?

Answer: TMP-SMX can increase the risk of hypoglycemia in patients taking sulfonylureas such as glipizide.

Patients taking both medications may require closer blood glucose monitoring and medication review. Signs of hypoglycemia should be recognized and treated promptly.

What is a common treatment option for uncomplicated cystitis?

Answer: Appropriate short-course antibiotic therapy is used when bacterial cystitis is suspected or confirmed.

Treatment should be selected according to current guidelines, patient-specific factors, allergies, kidney function, and local antimicrobial resistance patterns. Common options for appropriate patients include nitrofurantoin, trimethoprim-sulfamethoxazole, and fosfomycin.

What medication treats genital herpes?

Answer: Antiviral medications such as acyclovir or valacyclovir.

Antiviral therapy can reduce the severity and duration of genital herpes symptoms. Suppressive therapy may also reduce the frequency of outbreaks and transmission risk, although antiviral treatment does not eradicate latent HSV infection.

Lipid Management and Heart Failure Review

Which medication is commonly used for significant LDL cholesterol elevation and elevated ASCVD risk?

Answer: A statin is generally first-line pharmacologic therapy when indicated.

Statins reduce LDL cholesterol and cardiovascular risk. The appropriate intensity of statin therapy depends on factors such as LDL level, age, existing cardiovascular disease, diabetes status, and overall ASCVD risk.

How has treatment of HFrEF evolved?

Answer: Guideline-directed medical therapy commonly includes four major medication classes.

For appropriate patients with heart failure with reduced ejection fraction (HFrEF), contemporary treatment commonly includes:

• An ARNI, ACE inhibitor, or ARB

• An evidence-based beta blocker

• A mineralocorticoid receptor antagonist

• An SGLT2 inhibitor

Sacubitril/valsartan may be used instead of an ACE inhibitor or ARB in appropriate patients. Treatment is individualized according to kidney function, blood pressure, potassium levels, comorbidities, and tolerance.

Population Health and Genetics Review

What is incidence?

Answer: Incidence measures new cases of a disease occurring within a population during a specified period.

Incidence helps researchers and healthcare professionals understand how frequently new cases develop and can be used to evaluate changes in disease risk.

What is prevalence?

Answer: Prevalence measures the proportion of a population living with a disease or condition at a particular time or during a specified period.

Prevalence includes existing cases and is influenced by both the occurrence of disease and the length of time people live with the condition.

What is relative risk?

Answer: Relative risk compares disease incidence in an exposed group with disease incidence in an unexposed group.

A relative risk above 1 indicates higher incidence in the exposed group, while a relative risk below 1 indicates lower incidence. Relative risk is commonly used in epidemiologic research to examine associations between exposures and outcomes.

What does multifactorial inheritance mean?

Answer: Multifactorial traits result from interactions among multiple genes and environmental factors.

Many common health conditions involve complex genetic and environmental influences. Examples include hypertension, type 2 diabetes, obesity, coronary artery disease, and some cancers.

What is a gene-environment interaction?

Answer: It occurs when genetic susceptibility and environmental exposures work together to influence disease risk.

A family history may increase susceptibility without determining whether a person will develop a condition. Factors such as diet, physical activity, environmental exposures, stress, and other circumstances can influence disease expression.

How can family and twin studies help researchers understand disease?

Answer: They help researchers estimate the relative contributions of genetic and environmental factors.

Monozygotic twins share nearly all of their genetic material, whereas dizygotic twins share approximately half of their segregating genetic material. Comparing similarities and differences between twin pairs can provide useful information about heritable characteristics.

Health Disparities, Culture, and Complementary Therapies

What factors contribute to health disparities?

Answer: Social, economic, environmental, healthcare-system, and access-related factors can contribute to differences in health outcomes.

Health disparities are complex and may involve affordability, healthcare access, geographic location, health literacy, communication, quality of care, discrimination, and other social determinants of health.

How can clinicians improve health literacy?

Answer: Use plain language, confirm understanding, encourage questions, and provide information in the patient’s preferred language when needed.

Healthcare professionals should make information understandable and actionable. The teach-back method is especially useful because it allows clinicians to confirm that patients understand instructions rather than simply asking whether they understand.

What are the three domains of the PEN-3 cultural model?

Answer: Cultural identity, relationships and expectations, and cultural empowerment.

The PEN-3 model provides a framework for considering cultural influences when assessing health behaviors and planning appropriate health interventions.

What should nurses consider when patients use complementary or alternative therapies?

Answer: Ask about all supplements and complementary therapies and evaluate their safety, evidence, interactions, and adverse effects.

Patients may not consider herbal products to be medications, so nurses should specifically ask about supplements and alternative therapies. For example, kava has been associated with serious liver injury, while red yeast rice can contain compounds chemically related to lovastatin and may produce statin-like adverse effects.

Aging and Pediatric Health Review

What is a common cardiovascular change associated with aging?

Answer: Increased arterial stiffness can contribute to higher blood pressure and cardiovascular changes.

Aging can decrease vascular compliance and contribute to changes in blood pressure and cardiac function. However, new cardiovascular symptoms should not automatically be attributed to normal aging and require appropriate assessment.

What endocrine changes occur with aging?

Answer: Aging can affect thyroid, pancreatic, adrenal, reproductive, and other endocrine systems.

Changes in endocrine function may influence metabolism, body composition, glucose regulation, energy levels, and reproductive hormone levels.

What contributes to anorexia of aging?

Answer: Reduced appetite, altered taste and smell, hormonal changes, lower energy requirements, and social or medical factors can contribute.

Older adults may have lower caloric requirements while still being vulnerable to inadequate nutritional intake. Medication effects, chronic illness, oral health, depression, isolation, and difficulty accessing food can also contribute.

What causes menopausal hot flashes?

Answer: Changes in ovarian hormone production, particularly declining estrogen levels, contribute to vasomotor symptoms.

During the menopausal transition, changes in estrogen levels can affect the body’s thermoregulatory system. This can lead to episodes of sudden warmth, sweating, and flushing.

What is the most common childhood cancer?

Answer: Leukemia is the most commonly diagnosed cancer in children.

Although childhood cancer is uncommon compared with cancer in adults, leukemia represents a major category of pediatric malignancy. Advances in diagnosis and treatment have significantly improved survival for many childhood cancers.

What is an important long-term concern after childhood cancer treatment?

Answer: Cancer survivors may experience late effects related to the disease or its treatment.

Late effects vary according to the type of cancer and treatment received. They may involve endocrine, cardiovascular, neurologic, reproductive, psychosocial, and other body systems.

How should hypertension in children be evaluated?

Answer: Evaluation may include repeated blood pressure measurements, ambulatory blood pressure monitoring when appropriate, lifestyle assessment, and evaluation for secondary causes or target-organ effects.

Pediatric blood pressure must be interpreted using age-, sex-, and height-appropriate standards. Treatment can include lifestyle interventions and medication when clinically indicated.

How is asthma confirmed in an older child?

Answer: Spirometry demonstrating variable expiratory airflow limitation can support the diagnosis.

A family history of asthma or atopy and elevated IgE or eosinophil levels may provide supporting information but do not independently establish an asthma diagnosis.

What is a characteristic feature of cystic fibrosis?

Answer: Thick, sticky mucus is a defining feature of cystic fibrosis.

Cystic fibrosis affects multiple organ systems, particularly the respiratory and gastrointestinal systems. Patients may develop recurrent respiratory infections, pancreatic insufficiency, malnutrition, and cystic-fibrosis-related diabetes.

Medication Safety in Infants and Older Adults

Why may newborns require lower medication doses?

Answer: Immature hepatic and renal systems can alter medication metabolism and elimination.

Newborns have developing pharmacokinetic systems. As a result, certain medications may remain in the body longer or reach higher concentrations, increasing the potential for adverse effects and toxicity.

Why are infants particularly vulnerable to medication toxicity?

Answer: Immature hepatic metabolism, renal elimination, protein binding, and other physiologic systems can alter drug effects.

Medication dosing in infants requires careful consideration of developmental differences. Drugs with narrow therapeutic ranges require particularly careful dosing and monitoring.

What should a nurse assess when an older adult has a subtherapeutic medication level?

Answer: Assess medication adherence before assuming the dose needs to be increased.

The nurse should review missed doses, medication schedules, adverse effects, cost barriers, access to medication, and the patient’s understanding of the treatment plan. Increasing the dose without identifying the cause of the low level could create a risk of toxicity if the patient begins taking the medication consistently.

What is an important measure of kidney function in older adults taking multiple medications?

Answer: Estimated kidney function, such as eGFR or creatinine clearance when appropriate, should be considered.

Serum creatinine alone may not accurately represent kidney function in some older adults because creatinine production is influenced by muscle mass. Kidney function is important when determining the appropriate dose of many medications.

What complication can occur with excessive caffeine intake?

Answer: Severe caffeine toxicity can cause agitation, tremors, tachycardia, hypertension, and seizures.

Large quantities of caffeine, particularly concentrated caffeine products and some energy products, can cause significant cardiovascular and neurologic stimulation. Severe toxicity requires urgent medical evaluation.

What baseline information is important before starting methylphenidate in a child?

Answer: Height, weight, appetite, cardiovascular history, blood pressure, and heart rate should be assessed.

Methylphenidate can affect appetite and growth and may produce cardiovascular effects. Monitoring growth and cardiovascular parameters throughout treatment is therefore important.

Why are sedating cough medicines generally not recommended for young infants?

Answer: Young children are particularly vulnerable to serious adverse effects and central nervous system depression from certain cough and cold medications.

Many over-the-counter cough and cold products are not recommended for young children. Parents and caregivers should consult a pediatric healthcare professional before giving these products to infants or young children.

Immunization Review Questions and Answers

Where is the hepatitis B vaccine administered in infants?

Answer: The anterolateral thigh is the preferred intramuscular injection site for infants.

The vastus lateralis muscle provides an appropriate intramuscular injection site during infancy. Vaccine administration should follow current immunization recommendations and proper age-specific technique.

Which vaccine type is generally contraindicated in significantly immunocompromised children?

Answer: Certain live vaccines, such as varicella vaccine, may be contraindicated depending on immune status.

Live vaccines may pose a risk to patients with significant immunosuppression. Vaccine recommendations should be individualized according to the child’s immune condition and current CDC guidance. Inactivated vaccines are generally safer in immunocompromised patients, although their effectiveness may vary.

Medication Adverse Effects and Clinical Priorities

Which antihypertensive medication commonly causes a persistent dry cough?

Answer: Lisinopril and other ACE inhibitors.

A persistent dry cough is a classic adverse effect associated with ACE inhibitors. ARBs generally cause this type of cough much less frequently.

Which postoperative complaint requires priority assessment after IV morphine?

Answer: A spreading rash or reaction around the IV site requires prompt assessment.

The nurse should immediately assess the IV site and the patient for possible infiltration, phlebitis, tissue injury, or a systemic hypersensitivity reaction. The patient’s respiratory status and other vital signs should also be considered when an allergic reaction is suspected.

Which patient should receive priority assessment?

Answer: Priority should be based on acuity, instability, risk of deterioration, and immediate safety concerns.

Age alone does not determine nursing priority. When multiple patients appear stable, the nurse should identify the patient with the greatest risk for an acute complication and perform a focused assessment.

Pain Management Review Questions and Answers

Where does conscious pain perception occur?

Answer: Conscious pain perception involves processing within the cerebral cortex and interconnected central nervous system structures.

Pain is a complex experience rather than a function of one isolated brain region. Sensory, emotional, cognitive, and behavioral components involve multiple neural pathways and brain structures.

What type of pain warns of actual or potential tissue injury?

Answer: Acute pain.

Acute pain generally serves a protective function and is associated with actual or potential tissue injury. Chronic pain persists beyond expected healing and may involve complex biological, psychological, and social factors.

How do endogenous opioids reduce pain?

Answer: Endogenous opioids such as endorphins and enkephalins bind to opioid receptors and reduce pain signaling.

These naturally occurring substances influence pain transmission in the central and peripheral nervous systems by activating opioid receptors and inhibiting pain pathways.

What adverse effect after lidocaine with epinephrine requires attention?

Answer: Significant nervousness and tachycardia require assessment.

Epinephrine can produce temporary cardiovascular stimulation. However, pronounced nervousness, palpitations, tachycardia, or other concerning symptoms may indicate excessive systemic absorption or an adverse reaction and should be evaluated.

How should a transdermal buprenorphine patch be managed?

Answer: Apply it according to the prescribed schedule and rotate application sites.

Rotating application sites can reduce local skin irritation. Patients should follow the specific product instructions regarding placement, replacement, heat exposure, and disposal.

What are classic signs of opioid toxicity?

Answer: Respiratory depression, decreased level of consciousness, and pinpoint pupils.

Significant opioid toxicity can cause life-threatening respiratory depression. Immediate assessment and intervention are required. Naloxone may be administered when indicated, along with appropriate airway and ventilatory support.

When should sumatriptan be avoided?

Answer: It should be avoided in patients with certain cardiovascular conditions, including established coronary artery disease.

Sumatriptan and other triptans can cause vasoconstriction. Patients with specific cardiovascular contraindications should not use these medications unless a qualified healthcare professional determines that treatment is appropriate.

Which headache may respond rapidly to supplemental oxygen?

Answer: Cluster headache.

High-flow oxygen is an established acute treatment option for cluster headaches in appropriate patients. Other acute and preventive treatments may also be used based on the patient’s clinical needs.

Is acupuncture effective for cancer pain?

Answer: Acupuncture may be considered as a complementary therapy, although evidence varies according to the pain condition and clinical context.

Acupuncture should not automatically replace evidence-based cancer pain treatment. Complementary approaches should be discussed with the oncology team and incorporated safely into an individualized pain-management plan.

What is appropriate for severe cancer pain?

Answer: Opioid analgesics are an important treatment option for moderate-to-severe cancer pain.

Cancer pain treatment should be individualized according to pain severity, cause, previous opioid exposure, kidney and liver function, adverse effects, and patient goals. Nonopioid medications and nonpharmacologic interventions may also be combined with opioid therapy.

Mental Health Review: Schizophrenia and Mood Disorders

What are the major symptom categories of schizophrenia?

Answer: Positive, negative, and cognitive symptoms.

Positive symptoms include hallucinations and delusions. Negative symptoms may include reduced emotional expression, reduced motivation, and social withdrawal. Cognitive symptoms can affect attention, memory, processing, and executive functioning.

How is schizophrenia treated?

Answer: Treatment commonly combines antipsychotic medication with psychosocial interventions and supportive care.

First-generation and second-generation antipsychotics differ in their receptor activity and adverse-effect profiles. Treatment should be individualized according to symptoms, response, adverse effects, patient preferences, and overall treatment goals. Psychosocial interventions can support functioning, adherence, and recovery.

What characterizes major depressive disorder?

Answer: Major depressive disorder involves persistent depressed mood or loss of interest accompanied by additional symptoms that cause clinically significant distress or impairment.

Symptoms can include sleep disturbances, appetite or weight changes, fatigue, impaired concentration, feelings of worthlessness or guilt, psychomotor changes, and suicidal thoughts. Diagnosis requires a comprehensive assessment using established diagnostic criteria.

How does bipolar disorder differ from major depression?

Answer: Bipolar disorder includes episodes of mania or hypomania, with or without depressive episodes.

The presence of mania or hypomania distinguishes bipolar disorders from major depressive disorder. Treatment depends on the type and phase of bipolar disorder and may include mood stabilizers or certain atypical antipsychotics. Antidepressant monotherapy may be inappropriate for some patients with bipolar disorder.

Anxiety, PTSD, and OCD Review

What is a common complication associated with panic disorder?

Answer: Agoraphobia can occur with panic disorder.

Agoraphobia involves significant fear or avoidance of situations in which a person believes escape may be difficult or help may be unavailable. It can occur in association with recurrent panic attacks.

How long must excessive worry persist for generalized anxiety disorder?

Answer: At least six months.

Generalized anxiety disorder involves excessive, difficult-to-control worry about multiple areas of life for at least six months. Associated symptoms can include restlessness, fatigue, irritability, muscle tension, and sleep disturbance.

What is a common treatment approach for generalized anxiety disorder?

Answer: Psychotherapy, particularly cognitive behavioral therapy, and medications such as SSRIs or SNRIs are commonly used.

Treatment should be individualized according to symptom severity, comorbidities, patient preferences, and treatment response. Buspirone is another medication option and does not have the same dependence profile as benzodiazepines.

What is the significance of recurrent nightmares after trauma?

Answer: Recurrent nightmares may indicate trauma-related re-experiencing and should prompt assessment for PTSD or another trauma-related disorder.

Healthcare professionals should sensitively assess the patient’s trauma history and other symptoms. Recurrent trauma-related nightmares should be considered within the context of the person’s overall clinical presentation.

What is an evidence-based treatment approach for PTSD?

Answer: Trauma-focused psychotherapy is a major component of evidence-based PTSD treatment.

Trauma-focused therapies can help patients process traumatic experiences and develop healthier coping strategies. Certain medications, including SSRIs, may also be appropriate depending on symptoms, comorbidities, preferences, and treatment response.

What characterizes obsessive-compulsive disorder?

Answer: OCD involves recurrent obsessions, compulsions, or both that are time-consuming or cause significant distress or impairment.

Evidence-based treatment includes exposure and response prevention (ERP), a specialized form of cognitive behavioral therapy, and medications such as SSRIs. Severe or treatment-resistant OCD may require specialized psychiatric interventions.

Stress and Adaptation Review Questions

How does stress affect immunity?

Answer: Stress hormones, particularly cortisol, can alter immune function.

The body’s stress response involves neuroendocrine pathways that influence inflammatory and immune activity. Chronic or severe stress may have broader effects on immune regulation.

What is an important factor influencing an individual’s stress response?

Answer: The individual’s appraisal of the stressor and ability to cope can strongly influence the response.

People may react differently to the same stressful event because of differences in previous experiences, coping resources, social support, perceived control, and individual interpretation of the situation.

What causes cold, clammy skin during an acute stress response?

Answer: Sympathetic activation causes peripheral vasoconstriction and sweating.

During an acute stress response, sympathetic nervous system activity can redirect blood flow and stimulate sweat glands. This may result in cool, pale, or clammy skin.

What are the stages of the general adaptation syndrome?

Answer: Alarm, resistance, and exhaustion.

The alarm stage represents the body’s initial response to a stressor. During the resistance stage, the body attempts to adapt to continued stress. Prolonged stress without adequate recovery may eventually contribute to exhaustion.

What hormone contributes to stress-related hyperglycemia?

Answer: Cortisol.

Cortisol increases glucose availability through mechanisms such as stimulation of gluconeogenesis. Other stress hormones, including epinephrine and norepinephrine, can also contribute to elevated blood glucose during acute stress.

Acute Stress Disorder and PTSD

When can PTSD be diagnosed after trauma?

Answer: PTSD requires symptoms lasting longer than one month after the traumatic event.

Symptoms that occur from three days to one month after trauma may meet criteria for acute stress disorder, depending on the complete clinical presentation. Persistent symptoms beyond one month may meet criteria for PTSD.

What is a first-line treatment approach for acute stress disorder?

Answer: Trauma-focused cognitive behavioral therapy is an important evidence-based treatment approach.

Treatment can help individuals process the traumatic experience and develop effective coping strategies. Routine psychological debriefing is not recommended as a universal preventive intervention following trauma.

Why is prolonged benzodiazepine use concerning in trauma-related disorders?

Answer: Benzodiazepines can cause dependence, tolerance, sedation, and other adverse effects.

Long-term benzodiazepine use requires careful evaluation. These medications are not routinely recommended as a long-term treatment for PTSD and may interfere with effective trauma-focused treatment approaches.

Chronic and Cancer Pain Review

What medication can interact significantly with duloxetine?

Answer: Tramadol can increase the risk of serotonin toxicity when combined with serotonergic medications such as duloxetine.

Tramadol has opioid activity and also affects serotonin and norepinephrine pathways. Combining it with serotonergic medications can increase the risk of serotonin syndrome and other adverse effects.

What should be assessed first in unexplained chronic generalized pain?

Answer: A comprehensive assessment should include sleep, physical symptoms, medications, psychosocial factors, and functional status.

Poor sleep can increase pain sensitivity and contribute to fatigue. A broad assessment can help identify potential causes, contributing factors, medication-related problems, and appropriate treatment options.

What is an appropriate intervention for severe pain in a hospice patient?

Answer: Provide timely, appropriately prescribed analgesia while prioritizing comfort and the patient’s goals of care.

Hospice care emphasizes comfort, dignity, and quality of life for people with advanced illness. Severe pain should be assessed promptly and treated using an individualized plan that may include opioids and other supportive interventions.

Key Unit 4 Exam Takeaways

For the D027 Unit 4 exam, focus on recognizing the relationship between medications, adverse effects, contraindications, drug interactions, monitoring requirements, and patient education. High-yield associations include:

• ACE inhibitors: Persistent dry cough and pregnancy-related safety concerns.

• Spironolactone: Potassium retention and risk of hyperkalemia.

• Phenytoin: Reduced effectiveness of some hormonal contraceptives.

• Opioids: Respiratory depression, sedation, and pinpoint pupils in toxicity.

• LABAs: Should be used within an appropriate ICS-containing asthma regimen.

• Methotrexate: Disease-modifying treatment for rheumatoid arthritis.

• Rapid-acting insulin: Used around meals according to the prescribed regimen.

• Insulin glargine: Long-acting basal insulin.

• Epinephrine: First-line medication for anaphylaxis.

• Sumatriptan: Important cardiovascular contraindications.

• SSRIs/SNRIs and CBT: Common evidence-based approaches for anxiety and mood disorders.

• ERP: An important behavioral treatment for OCD.

• Trauma-focused psychotherapy: A major evidence-based approach for PTSD.

• Incidence: Measures new cases.

• Prevalence: Measures existing cases.

• Relative risk: Compares disease incidence between exposed and unexposed groups.

For exam preparation, also distinguish acute treatment from long-term management and recognize that medication decisions depend on individual patient factors. Clinical guidelines can change over time, so contemporary recommendations should take priority when older study materials conflict with current practice.
