Match each of the following ambulatory patient profiles with the single most appropriate guideline-concordant preventive care intervention. Each patient is asymptomatic, has no acute complaints, and has a normal physical examination today.

Paramedics rush a 27-year-old male to the trauma center following a high-speed motorcycle collision. The patient is visibly distressed, confused, and diaphoretic. His temperature is 36.5°C (97.7°F), pulse is 132/min, blood pressure is 84/52 mm Hg, and respiratory rate is 28/min. Pulse oximetry shows 89% on room air. Physical assessment demonstrates leftward tracheal deviation, and breath sounds are absent over the right hemithorax with marked percussion dullness. Intravenous access is rapidly established and volume resuscitation is initiated. A 32-French thoracostomy tube is inserted into the right midaxillary line, yielding an immediate return of 1,600 mL of bright red blood. Over the subsequent 15 minutes, an additional 150 mL drains. The patient's blood pressure remains 82/50 mm Hg despite rapid infusion of 2 L of warmed crystalloid and 1 unit of uncrossmatched packed red blood cells. Which of the following is the most appropriate next step in management?

An established 38-year-old female patient presents for follow-up regarding resistant hypertension. She reports experiencing profound muscle cramps and episodic weakness over the last month. Clinical assessment reveals a blood pressure of 168/102 mm Hg, which has remained uncontrolled despite strict adherence to maximum tolerated doses of lisinopril, amlodipine, and hydrochlorothiazide. A basic metabolic panel highlights a serum potassium level of 2.8 mEq/L. Suspecting primary hyperaldosteronism, the physician tapers her interfering medications, transitions her to doxazosin, and normalizes her potassium. Arrange the subsequent diagnostic investigations in the correct chronological order, proceeding from the initial diagnostic step to the definitive pre-surgical assessment.

A 72-year-old man comes to the clinic for a routine follow-up. He has a history of ischemic cardiomyopathy with a severely reduced left ventricular ejection fraction and recurrent, symptomatic ventricular tachycardia.
