As shown in the table above, unintentional injuries are the leading cause of death as far as years of potential life lost before age 65 (YPLL–65), and yet the cause-specific crude mortality from unintentional injuries is much lower than that from malignant neoplasms or from diseases of the heart.  The reason(s) for this is(are):  I. YPLL-65 was used when YPLL-75 would have been more appropriate  II. Column I of this table includes persons dying after age 65, while Column II does not  III. Persons dying from unintentional injuries are much younger on the average than persons dying from both malignant neoplasms and heart disease.

During a preparticipation sports examination, a 20-year-old asymptomatic patient is found to have a grade 2/6 early-to-mid systolic ejection murmur heard best at the left upper sternal border. The murmur becomes softer when the patient moves from the supine to standing position. The remainder of the cardiovascular examination is normal. Which finding is most consistent with this presentation?

A 72-year-old patient with chronic heart failure presents with worsening dyspnea. The patient now requires several pillows to sleep and reports awakening at night with severe shortness of breath. Examination reveals jugular venous distention, pulmonary crackles, and bilateral peripheral edema. Which finding would most strongly indicate progression to acute decompensated heart failure?

A 59-year-old woman presents to primary care with new shortness of breath that began earlier that morning. She returned from a long international flight 3 days ago. HR is 108 beats/min, RR 24 breaths/min, BP 126/78 mm Hg, and SpO₂ is 89% on room air. Lung sounds are clear bilaterally. She reports mild right calf discomfort but denies fever or productive cough. Which action is most appropriate?

A 47-year-old woman presents with unilateral calf swelling and tenderness 2 days after returning from an international trip. She has no history of trauma or recent surgery and does not take estrogen-containing medications. She reports spending most of the 10-hour flight seated and sleeping without getting up to walk. Which pathophysiologic mechanism most directly contributed to her increased risk for venous thrombosis?

A 14-year-old with a previous episode of acute rheumatic fever and carditis has no residual valvular disease. The adolescent has been receiving benzathine penicillin G every 4 weeks.
