Health Histories And Screenings - NAPLEX

  1. A 46-year-old woman (64 kg) requests help choosing an over-the-counter cold product. Medical history: major depressive disorder, hypertension. Medications: phenelzine 15 mg three times daily, hydrochlorothiazide 25 mg daily. Allergies: none. Blood pressure today: 150/92 mmHg. What counseling point is crucial for this patient based on their medication history?
    Answer: Avoid decongestants like pseudoephedrine due to risk of hypertensive crisis with monoamine oxidase inhibitors and uncontrolled blood pressure; recommend safer alternatives (e.g., saline, guaifenesin if appropriate) This question tests the concept of OTC product selection safety with monoamine oxidase inhibitors to prevent hypertensive crises. The key patient-specific factor is phenelzine use with uncontrolled hypertension, contraindicating sympathomimetics like pseudoephedrine. Choice A is the best counseling because avoiding decongestants and recommending alternatives like saline prevents interactions. Choice B is incorrect as pseudoephedrine with food does not eliminate risk; choice C is wrong because dextromethorphan can interact via serotonin. Choice D is suboptimal as stopping phenelzine risks psychiatric decompensation. A transferable pearl is that MAOIs have broad interactions with tyramine and sympathomimetics. Guide patients to non-interacting OTC options.
  2. A 50-year-old man (90 kg) presents for a community blood pressure screening. Average of three readings is 136/84 mmHg. Medical history: no known chronic diseases. Medications: none. Labs from last month: fasting glucose 98 mg/dL, LDL-C 122 mg/dL. Lifestyle: smokes 0.5 pack/day; drinks 1–2 drinks/day; diet high in processed foods. What lifestyle modification should be recommended to this patient?
    Answer: Recommend smoking cessation and adopting the DASH-style eating pattern to help reduce blood pressure and cardiovascular risk This question tests the concept of lifestyle modifications for prehypertension management to reduce cardiovascular risk. The key patient-specific factor is the blood pressure of 136/84 mmHg with smoking, alcohol use, and high-sodium diet, indicating stage 1 hypertension risk. Choice A is the best recommendation because smoking cessation and DASH diet effectively lower blood pressure and CVD risk. Choice B is incorrect as increasing sodium worsens hypertension; choice C is wrong because physical activity is encouraged, not avoided. Choice D is suboptimal as vitamin E is not evidence-based for blood pressure control. A transferable pearl is to prioritize smoking cessation and dietary changes in initial hypertension management. Use motivational interviewing to support sustainable lifestyle changes.
  3. A 39-year-old woman (76 kg) with obesity asks about starting an over-the-counter weight-loss supplement. Medical history: prediabetes; last labs: HbA1c 6.1% (prediabetes range 5.7–6.4), fasting glucose 112 mg/dL. Medications: none. Blood pressure today: 138/88 mmHg. Lifestyle: drinks sugar-sweetened beverages daily; sleeps 5 hours/night; no regular exercise. What lifestyle modification should be recommended to this patient?
    Answer: Recommend a structured plan targeting 5%–10% weight loss through calorie reduction and at least 150 minutes/week of moderate-intensity activity This question tests the concept of lifestyle interventions for obesity and prediabetes to prevent progression to diabetes. The key patient-specific factor is the patient's obesity (76 kg), prediabetes (HbA1c 6.1%), and habits like sugary drinks and sedentary lifestyle. Choice A is the best recommendation because targeting 5-10% weight loss via diet and 150 min/week activity is evidence-based for prediabetes management. Choice B is incorrect as stimulant supplements are unsafe and not recommended; choice C is wrong because extreme carb avoidance is unsustainable. Choice D is suboptimal as delaying changes until HbA1c 7.0% misses prevention opportunity. A transferable pearl is that modest weight loss can reduce diabetes risk by 58% in prediabetes. Tailor plans to patient barriers for better adherence.
  4. A 60-year-old man (85 kg) asks about his new over-the-counter "heartburn medicine." Medication list: rilpivirine/tenofovir alafenamide/emtricitabine 1 tablet daily for HIV, calcium carbonate as needed, and a new OTC famotidine 20 mg twice daily. Medical history: HIV (viral load undetectable), hyperlipidemia. Labs: LDL-C 110 mg/dL. Allergies: none. What counseling point is crucial for this patient based on their medication history?
    Answer: Advise that acid-reducing agents can decrease rilpivirine absorption; separate famotidine dosing appropriately or consult prescriber for alternative reflux management This question tests the concept of drug interactions affecting antiretroviral absorption, specifically acid reducers with rilpivirine. The key patient-specific factor is the new OTC famotidine with rilpivirine, where acid suppression can decrease rilpivirine bioavailability and efficacy. Choice A is the best counseling because advising separation or alternatives prevents virologic failure. Choice B is incorrect as same-time dosing worsens the interaction; choice C is wrong because stopping ART is harmful. Choice D is suboptimal as PPIs like omeprazole are contraindicated with rilpivirine. A transferable pearl is that rilpivirine requires gastric acidity for absorption. Always check OTC additions for ART interactions.
  5. A 58-year-old man (92 kg) presents to the pharmacy after a community health fair screening showed blood pressure 168/96 mmHg and a repeat reading today in the pharmacy is 166/94 mmHg; he has no acute symptoms and is here for advice. Medical history includes type 2 diabetes (HbA1c 8.2%), hyperlipidemia (LDL 142 mg/dL), and no prior cardiovascular events; medications are metformin 1000 mg twice daily, atorvastatin 20 mg nightly, and ibuprofen 400 mg as needed for knee pain. Allergies: lisinopril caused facial swelling requiring emergency care. Lifestyle: smokes 1 pack/day, drinks 2–3 beers nightly, high-sodium diet; last primary care visit was 2 years ago. What is the most important follow-up action based on this patient's screening results?
    Answer: Recommend home blood pressure monitoring and follow up with a primary care provider within 1 week for confirmation and initiation/intensification of antihypertensive therapy This question tests the pharmacist's role in managing hypertensive urgency discovered during community screening. The patient presents with stage 2 hypertension (168/96 mmHg confirmed by 166/94 mmHg) without acute symptoms, multiple cardiovascular risk factors, and a documented ACE inhibitor allergy (angioedema). Option A is correct because it follows guidelines for newly diagnosed severe hypertension: confirm readings with home monitoring and ensure prompt medical follow-up within 1 week for treatment initiation. Option B is incorrect as it dismisses significantly elevated readings that require intervention. Option C is contraindicated due to the patient's history of ACE inhibitor-induced angioedema, which is a class effect. Option D is inadequate as it addresses only one risk factor and delays necessary medical care for stage 2 hypertension. The clinical pearl is that pharmacists should facilitate prompt medical follow-up for severe hypertension while avoiding contraindicated medications based on allergy history.
  6. A 52-year-old man (105 kg) with gastroesophageal reflux disease asks why his clopidogrel "is not working as well." Medication list: clopidogrel 75 mg daily (post-stent 6 months ago), omeprazole 40 mg daily (self-started OTC 2 months ago), metoprolol succinate 50 mg daily, rosuvastatin 20 mg nightly. Medical history: coronary artery disease, hypertension; allergies: none. Vitals: blood pressure 126/78 mmHg. Lifestyle: drinks 3–4 alcoholic drinks on weekends. What counseling point is crucial for this patient based on their medication history?
    Answer: Recommend switching omeprazole to pantoprazole (or using an H2-receptor antagonist if appropriate) due to reduced clopidogrel activation with omeprazole This question tests the concept of identifying drug-drug interactions, specifically CYP2C19 inhibition by proton pump inhibitors affecting clopidogrel efficacy. The key patient-specific factor is the recent self-initiation of omeprazole 40 mg daily with clopidogrel, potentially reducing clopidogrel activation and increasing thrombotic risk post-stent. Choice A is the best recommendation because switching to pantoprazole or an H2-antagonist minimizes the interaction while maintaining acid suppression. Choice B is incorrect as doubling clopidogrel is not standard and may increase bleeding risk; choice C is wrong because statins like rosuvastatin do not significantly reduce clopidogrel effectiveness. Choice D is suboptimal as timing separation does not fully eliminate the CYP-mediated interaction. A clinical pearl is to prefer pantoprazole or ranitidine with clopidogrel when PPI therapy is needed. Always assess self-started OTC medications for interactions in high-risk patients.
  7. A 70-year-old man (80 kg) presents to the pharmacy with his home medication list after seeing a new primary care provider. He currently takes: warfarin (variable dosing; INR goal 2–3), amiodarone 200 mg daily, levothyroxine 75 mcg daily, and a new prescription for trimethoprim-sulfamethoxazole double strength 1 tablet twice daily for 7 days. Medical history: atrial fibrillation, hypothyroidism; allergies: none. Most recent INR 2.4 (1 week ago). What is the most important follow-up action based on this patient's medication history?
    Answer: Contact the prescriber to recommend an alternative antibiotic or plan for closer INR monitoring and warfarin dose adjustment due to increased bleeding risk This question tests the concept of managing drug-drug interactions with warfarin, particularly antibiotics that potentiate anticoagulation. The key patient-specific factor is the new prescription for trimethoprim-sulfamethoxazole, which inhibits warfarin metabolism and increases INR/bleeding risk, especially with recent therapeutic INR of 2.4. Choice B is the best action because contacting the prescriber for alternatives or monitoring plans prevents adverse events. Choice A is incorrect as dispensing without monitoring risks bleeding; choice C is wrong because antibiotics like TMP-SMX typically increase, not reduce, INR. Choice D is suboptimal as stopping amiodarone abruptly could destabilize atrial fibrillation. A clinical pearl is to anticipate INR elevation with TMP-SMX and plan weekly monitoring. Use interaction checkers and educate patients on signs of bleeding when adding interacting drugs to warfarin.
  8. A 55-year-old man (100 kg) with chronic knee pain asks for an over-the-counter product. Medical history: peptic ulcer disease with prior gastrointestinal bleed, hypertension. Medications: lisinopril 20 mg daily, omeprazole 20 mg daily. Allergies: aspirin (caused hives). Blood pressure today: 146/90 mmHg. What counseling point is crucial for this patient based on their medication history?
    Answer: Recommend acetaminophen as first-line OTC analgesic and avoid nonselective NSAIDs due to prior GI bleed and potential blood pressure effects This question tests the concept of safe OTC analgesic selection in patients with GI bleed history and hypertension. The key patient-specific factor is prior GI bleed, aspirin allergy (hives), and omeprazole use, making nonselective NSAIDs high-risk for recurrence and BP elevation. Choice B is the best counseling because recommending acetaminophen avoids NSAID risks while providing analgesia. Choice A is incorrect as PPIs reduce but do not fully prevent NSAID bleeding; choice C is wrong because naproxen shares similar risks. Choice D is suboptimal due to allergy and unnecessary for inflammation. A transferable pearl is to prefer acetaminophen in GI-risk patients. Assess comorbidities when recommending OTC pain relief.
  9. A 71-year-old man (76 kg) with atrial fibrillation presents for a comprehensive medication review after being discharged from the hospital 1 week ago. He is prescribed apixaban 5 mg twice daily, but he admits he often skips the evening dose because it is "hard to remember," and he has no pill organizer; he takes diltiazem extended-release 240 mg daily, atorvastatin 40 mg nightly, and a multivitamin. Vitals: blood pressure 126/74 mmHg; labs: serum creatinine 1.1 mg/dL. Allergies: none; lifestyle: drinks 1–2 alcoholic drinks nightly. What is the best strategy to improve this patient's medication adherence?
    Answer: Recommend a daily pill organizer and set a consistent reminder (phone alarm) tied to an evening routine to support taking the second daily dose This question addresses medication adherence strategies for twice-daily anticoagulation in atrial fibrillation. The patient admits to missing evening apixaban doses, creating stroke risk due to the drug's 12-hour half-life requiring consistent twice-daily dosing. Option B is correct because practical adherence tools (pill organizer) combined with behavioral strategies (phone alarms linked to routine activities) effectively improve twice-daily medication adherence. Option A is incorrect as warfarin requires more complex monitoring and doesn't guarantee better adherence. Option C is dangerous because taking both doses together creates bleeding risk followed by subtherapeutic anticoagulation. Option D is extremely dangerous as skipping anticoagulation doses increases stroke risk in atrial fibrillation. The clinical pearl is that twice-daily medications require specific adherence strategies beyond simple reminders, including environmental cues and routine integration.
  10. A 72-year-old woman (69 kg) comes in for a preventive care check. Medical history: no history of shingles; had chickenpox as a child. Medications: none. Allergies: neomycin (rash). Vitals: blood pressure 122/76 mmHg. Which screening is most appropriate given this patient's medical history?
    Answer: Recommend recombinant zoster vaccine series because it is indicated for adults aged 50 years and older, and neomycin allergy is not a contraindication This question tests the concept of shingles vaccination recommendations in older adults, considering allergies and vaccine types. The key patient-specific factor is age 72 with neomycin allergy (rash), but recombinant zoster vaccine does not contain neomycin and is preferred. Choice A is the best screening because recombinant zoster is indicated for adults 50+ regardless of shingles history. Choice B is incorrect as live zoster is no longer recommended; choice C is wrong because vaccination prevents primary shingles. Choice D is suboptimal as it's not annual. A clinical pearl is that recombinant zoster is safe with neomycin allergy. Vaccinate all eligible adults to reduce shingles burden.
  11. A 24-year-old woman (58 kg) presents for a refill of her combined oral contraceptive (ethinyl estradiol/norgestimate) and asks about preventive care. Medical history: no chronic conditions; medications: combined oral contraceptive daily and occasional acetaminophen. Screenings: last cervical cancer screening was never; she is sexually active with one male partner; blood pressure today is 118/72 mmHg. Allergies: none. Lifestyle: does not smoke; drinks alcohol 1–2 drinks/week. Which screening is most appropriate given this patient's medical history?
    Answer: Begin cervical cancer screening now with a Pap test and continue at recommended intervals for her age group This question evaluates knowledge of age-appropriate cancer screening guidelines for young adults. The patient is a sexually active 24-year-old woman who has never had cervical cancer screening. Option A is correct because cervical cancer screening should begin at age 21 regardless of sexual activity status, and she's overdue at age 24. Option B is incorrect as screening mammography typically begins at age 40-50 depending on risk factors, and hormonal contraception doesn't change this. Option C is wrong because colorectal cancer screening begins at age 45 in average-risk individuals. Option D is inappropriate as bone density screening begins at age 65 for women without risk factors, and being normal weight doesn't warrant early screening. The key principle is that cervical cancer screening begins at age 21 for all women and continues at regular intervals regardless of sexual history or contraceptive use.
  12. A 65-year-old man (84 kg) presents for a colorectal cancer screening consult. Medical history: type 2 diabetes and hypertension. Medications: metformin 1000 mg twice daily, insulin glargine 18 units nightly, chlorthalidone 25 mg daily. Labs: HbA1c 7.2%. Allergies: none. He has never had colorectal cancer screening and has no family history of colorectal cancer. Which screening is most appropriate given this patient's medical history?
    Answer: Recommend initiating age-appropriate colorectal cancer screening now (e.g., stool-based test or colonoscopy) and coordinate referral to primary care/gastroenterology This question assesses knowledge of evidence-based colorectal cancer screening guidelines, particularly for patients with comorbidities like diabetes. The key patient-specific factors are the patient's age of 65 years, lack of prior screening, and presence of type 2 diabetes, which may slightly elevate colorectal cancer risk but does not alter standard screening initiation. Choice A is the best recommendation because USPSTF guidelines advise starting colorectal cancer screening between ages 45-50 and continuing until age 75 for average-risk individuals, with options like stool-based tests or colonoscopy being appropriate now given his age and unscreened status. Choice B is incorrect as delaying until age 75 would miss the recommended screening window and increase risk of undetected disease; choice C is suboptimal because screening is preventive and should not wait for symptoms, which often indicate advanced disease; choice D is excessive as annual colonoscopies are not standard for diabetic patients without high-risk factors like family history or prior polyps. A transferable clinical pearl is that diabetes is associated with higher colorectal cancer incidence, underscoring the importance of adhering to screening timelines in this population. A decision framework for screening involves assessing age, risk factors (e.g., family history, comorbidities), and patient preferences to select modalities like non-invasive stool tests for those hesitant about colonoscopy.
  13. A 62-year-old woman (60 kg) presents for a medication therapy management visit. Medical history: osteoporosis and gastroesophageal reflux disease. Medications: alendronate 70 mg once weekly, calcium carbonate 500 mg twice daily, vitamin D3 1000 units daily, omeprazole 20 mg daily. She reports taking alendronate with breakfast and then lying back down due to nausea. Allergies: none. What counseling point is crucial for this patient based on their medication history?
    Answer: Take alendronate with a full glass of plain water on an empty stomach and remain upright for at least 30 minutes before eating or drinking anything else This question tests the concept of proper administration of bisphosphonates to optimize efficacy and minimize adverse effects. The key patient-specific factor is the patient's habit of taking alendronate with breakfast and lying down, increasing risk of esophageal irritation in GERD. Choice A is the best counseling because taking with water on empty stomach and staying upright ensures absorption and reduces reflux. Choice B is incorrect as orange juice impairs absorption; choice C is wrong because crushing alters release and increases irritation. Choice D is suboptimal as bedtime dosing heightens reflux risk. A clinical pearl is that bisphosphonates require specific administration to prevent GI adverse effects. Educate on adherence to improve osteoporosis outcomes.
  14. A 63-year-old woman (70 kg) comes to the pharmacy for a blood pressure check and vaccine advice. Medical history: type 2 diabetes (HbA1c 7.4%), chronic kidney disease stage 3a (estimated glomerular filtration rate 52 mL/min/1.73 m2^2), and hyperlipidemia; medications: metformin 500 mg twice daily, losartan 100 mg daily, and rosuvastatin 10 mg nightly. Vitals: blood pressure 134/82 mmHg; labs: LDL 88 mg/dL. Allergies: anaphylaxis to eggs as a child (hives and wheezing requiring epinephrine). Lifestyle: no smoking; drinks wine on weekends. Which screening is most appropriate given this patient's medical history?
    Answer: Annual urine albumin-to-creatinine ratio screening for diabetic kidney disease progression This question assesses knowledge of appropriate screening recommendations for patients with diabetes and chronic kidney disease. The patient has diabetes with CKD stage 3a, making annual monitoring for diabetic nephropathy progression essential. Option A is correct because annual urine albumin-to-creatinine ratio screening is guideline-recommended for all diabetic patients to detect and monitor kidney disease progression. Option B is incorrect as DEXA scanning isn't indicated until age 65 in women without additional risk factors, and diabetes alone doesn't warrant more frequent screening. Option C is inappropriate because coronary calcium scoring isn't recommended for routine screening, especially with well-controlled LDL. Option D is wrong as screening colonoscopy begins at age 45-50 and is performed every 10 years, not annually, and CKD doesn't change this schedule. The clinical principle is that diabetes requires specific annual screenings including nephropathy monitoring, regardless of current kidney function.
  15. A 63-year-old man (86 kg) presents for diabetes follow-up at a pharmacist-run clinic. Medical history: type 2 diabetes, hypertension. Medications: metformin 1000 mg twice daily, semaglutide 0.5 mg weekly, losartan 100 mg daily. Labs: HbA1c 6.8%, urine albumin-to-creatinine ratio (UACR) 120 mg/g (normal <30), eGFR 68 mL/min/1.73 m2^2. Blood pressure: 128/78 mmHg. What is the most important follow-up action based on this patient's screening results?
    Answer: Recommend adding an SGLT2 inhibitor (if appropriate) or coordinating with prescriber for kidney-protective therapy and ongoing albuminuria monitoring This question tests the concept of managing albuminuria in diabetic kidney disease for nephroprotection. The key patient-specific factor is elevated UACR of 120 mg/g despite losartan and controlled HbA1c, indicating need for additional therapy. Choice B is the best action because recommending SGLT2 inhibitor addition (if appropriate) provides kidney protection per guidelines. Choice A is incorrect as UACR 120 is abnormal and requires intervention; choice C is wrong because ARBs like losartan reduce albuminuria. Choice D is suboptimal as increasing semaglutide primarily for albuminuria is not first-line. A clinical pearl is that SGLT2 inhibitors slow CKD progression in diabetes. Monitor UACR annually in diabetic patients for early intervention.
  16. A 64-year-old woman (66 kg) comes to the pharmacy for a vaccination review. Medical history: chronic obstructive pulmonary disease, type 2 diabetes, and chronic heart failure. Medications: tiotropium inhaler daily, albuterol inhaler as needed, metformin 500 mg twice daily, carvedilol 12.5 mg twice daily, furosemide 40 mg daily. Allergies: eggs (hives). Vitals: blood pressure 130/76 mmHg. Which screening is most appropriate given this patient's medical history?
    Answer: Assess pneumococcal vaccination status and recommend age/condition-appropriate pneumococcal vaccination in addition to annual influenza vaccination This question tests the concept of immunization screening in patients with multiple chronic conditions, prioritizing vaccines based on age and comorbidities. The key patient-specific factor is the patient's age of 64 with COPD, diabetes, and heart failure, increasing risk for pneumococcal disease and influenza complications. Choice B is the best action because assessing pneumococcal status and recommending it alongside annual influenza aligns with guidelines for high-risk adults. Choice A is incorrect as egg allergy with hives is not a contraindication to influenza vaccines; choice C is wrong because MMR is not annually recommended for COPD. Choice D is suboptimal as Td booster is every 10 years, not annually for diabetes. A clinical pearl is that patients 65+ or with chronic conditions need pneumococcal and annual flu vaccines. Use shared decision-making to address vaccine hesitancy in multimorbid patients.
  17. A 73-year-old man (78 kg) brings in his medication bottles for reconciliation. He reports taking: metoprolol tartrate 50 mg twice daily, metoprolol succinate 50 mg twice daily, and diltiazem extended-release 240 mg daily. Medical history: hypertension and atrial fibrillation. Vitals: heart rate 48 beats/min, blood pressure 98/60 mmHg; he feels dizzy when standing. Allergies: none. What is the most important follow-up action based on this patient's medication history?
    Answer: Urgently contact the prescriber to clarify duplicate beta-blocker formulations and excessive rate-control therapy contributing to symptomatic bradycardia/hypotension This question tests the concept of identifying therapeutic duplication and excessive rate-control in atrial fibrillation management. The key patient-specific factor is the concurrent use of metoprolol tartrate and succinate (duplication) plus diltiazem, leading to symptomatic bradycardia (HR 48) and hypotension. Choice C is the best action because urgently contacting the prescriber clarifies the regimen and prevents harm from over-treatment. Choice A is incorrect as bradycardia is not expected and causes symptoms; choice B is wrong because digoxin would further lower heart rate. Choice D is suboptimal as combining doses does not resolve duplication. A clinical pearl is to reconcile medications for duplications in polypharmacy. Monitor vitals and symptoms to detect adverse effects from rate-control agents.
  18. A 23-year-old woman (59 kg) requests emergency contraception. She takes carbamazepine 400 mg twice daily for epilepsy and uses a combined oral contraceptive inconsistently. Allergies: none. Vitals: blood pressure 110/68 mmHg. Lifestyle: no smoking. What is the most important follow-up action based on this patient's medication history?
    Answer: Recommend a copper intrauterine device referral as the most effective emergency contraception option with carbamazepine use This question tests the concept of emergency contraception selection in the context of drug interactions with enzyme inducers. The key patient-specific factor is the use of carbamazepine, a strong CYP3A4 inducer that reduces efficacy of hormonal emergency contraceptives like levonorgestrel or ulipristal. Choice C is the best action because recommending copper IUD referral provides the most effective option unaffected by inducers. Choice A is incorrect as enzyme inducers decrease, not increase, levonorgestrel effectiveness; choice B is wrong because ulipristal is also affected by inducers. Choice D is suboptimal as carbamazepine does not provide contraception. A transferable pearl is that non-hormonal methods like copper IUD are preferred with enzyme inducers. Counsel on consistent contraception use to prevent unintended pregnancies.
  19. A 56-year-old man (96 kg) with type 2 diabetes comes for refill pickup. Medication list: empagliflozin 25 mg daily, metformin extended-release 1000 mg nightly, lisinopril 10 mg daily, atorvastatin 40 mg nightly. Labs: HbA1c 8.6%, serum creatinine 1.1 mg/dL, eGFR 78 mL/min/1.73 m2^2. He reports frequent genital yeast infections since starting empagliflozin and says he sometimes skips doses. Lifestyle: works outdoors and occasionally becomes dehydrated. What is the best strategy to improve this patient's medication adherence?
    Answer: Assess and address adverse effects (genital infections, dehydration risk), counsel on hygiene/hydration, and coordinate with prescriber on alternative therapy if needed This question tests the concept of addressing medication nonadherence due to adverse effects in diabetes management. The key patient-specific factor is frequent genital yeast infections with empagliflozin, leading to skipped doses, and outdoor work increasing dehydration risk. Choice A is the best strategy because assessing effects, counseling on prevention, and coordinating alternatives improves adherence safely. Choice B is incorrect as PRN use is ineffective for SGLT2 inhibitors; choice C is wrong because stopping lisinopril does not address infections. Choice D is suboptimal as prophylactic antifungals without follow-up may mask issues. A transferable pearl is to proactively counsel on SGLT2i side effects like infections. Use adherence tools and prescriber collaboration for persistent issues.
  20. A 60-year-old man (90 kg) with osteoarthritis asks for an over-the-counter pain option. Medical history: hypertension and peptic ulcer disease with a prior gastrointestinal bleed; medications: aspirin 81 mg daily for secondary prevention after a myocardial infarction, lisinopril 20 mg daily, and pantoprazole 40 mg daily. Vitals: blood pressure 142/88 mmHg; labs: hemoglobin 13.2 g/dL. Allergies: naproxen caused hives and lip swelling. Lifestyle: drinks 3–4 alcoholic drinks on weekends; no smoking. Which medication adjustment is necessary for this patient's condition?
    Answer: Recommend acetaminophen up to 3000 mg/day as needed and avoid nonsteroidal anti-inflammatory drugs due to prior gastrointestinal bleed and naproxen allergy history This question tests safe analgesic selection considering contraindications and drug allergies. The patient has multiple NSAID contraindications: prior GI bleed, current aspirin use, documented NSAID allergy (naproxen), and regular alcohol use. Option B is correct because acetaminophen is the safest option, though limited to 3000 mg/day due to regular alcohol intake, and NSAIDs must be avoided given his risk factors and allergy history. Option A is contraindicated due to GI bleed history and concurrent aspirin. Option C is absolutely contraindicated due to documented naproxen allergy (hives and angioedema indicate IgE-mediated reaction). Option D is incorrect as clopidogrel is an antiplatelet without analgesic properties and would increase bleeding risk. The key principle is that patients with NSAID allergies and GI bleeding history should use acetaminophen as first-line analgesia, with dose adjustment for alcohol use.
