Practice targeted AMC-style multiple-choice questions on aspirin.
A 72-year-old man with a history of hypertension, type 2 diabetes, and chronic kidney disease (CKD) presents to his general practitioner for a routine check-up. His current medications include metformin, insulin glargine, amlodipine, and aspirin. His blood pressure today is 150/90 mmHg. Laboratory results show a serum creatinine of 2.5 mg/dL (baseline 2.0 mg/dL), potassium of 5.4 mEq/L, and a urine albumin-to-creatinine ratio (ACR) of 350 mg/g. The GP decides to add an ACE inhibitor to his medication regimen to help manage his blood pressure and proteinuria. One week later, the patient returns complaining of fatigue and muscle weakness. Repeat laboratory testing reveals a serum creatinine of 3.1 mg/dL and a potassium of 6.2 mEq/L. Which of the following is the most appropriate next step in managing this patient?

His current medications include metformin, insulin, amlodipine, and aspirin. His blood pressure today is 150/90 mmHg. Laboratory results show a serum creatinine of 2.5 mg/dL (221 micromol/L) and a potassium level of 5.4 mEq/L. The GP decides to add an ACE inhibitor to his treatment regimen to help manage his blood pressure and provide renal protection. One week later, the patient returns complaining of fatigue and muscle weakness. Repeat laboratory tests reveal a serum creatinine of 3.1 mg/dL (274 micromol/L) and a potassium level of 6.2 mEq/L. Which of the following is the most appropriate next step in managing this patient?
A 78-year-old man with a history of chronic atrial fibrillation and hypertension presents to the emergency department with sudden onset of severe pain, numbness, and coldness in his left leg, starting approximately 3 hours ago. He is currently taking aspirin 100mg daily. On examination, his left foot and lower calf are pale and cool to touch. Pedal pulses are absent, popliteal pulse is weak. Sensation is decreased below the ankle, and motor function is preserved but weak. Capillary refill in the toes is delayed. His heart rate is irregularly irregular at 95 bpm, blood pressure 140/85 mmHg. What is the most appropriate initial management step?
A 68-year-old man with a history of hypertension, type 2 diabetes, and stable angina is scheduled for elective hernia repair surgery. He is currently on aspirin, metformin, lisinopril, and atorvastatin. His last angina episode was over a year ago, and he has no history of myocardial infarction. What is the most appropriate preoperative management step to minimize his cardiovascular risk during surgery?
A 72-year-old male presents with increasing shortness of breath and epigastric discomfort, particularly after meals. He has a history of well-controlled hypertension and takes aspirin daily. An X-ray is performed. What is the most appropriate next step in management?
