input: The following are multiple choice questions (with answers) about medical knowledge.   **Question:** A 67-year-old man presents to his primary care physician for a follow up appointment. He was released from the hospital 1 week ago for an appropriately managed ST-elevation myocardial infarction (STEMI); however, he has not filled any of his prescriptions and did not attend his follow up appointment as scheduled. The patient has a past medical history of hypertension and peripheral vascular disease. His temperature is 97.5°F (36.4°C), blood pressure is 167/118 mmHg, pulse is 90/min, respirations are 14/min, and oxygen saturation is 99% on room air. Physical exam is notable for jugular venous distention and bilateral lower extremity pitting edema. Echocardiography demonstrates an ejection fraction of 55%. Which of the following medications will have the greatest mortality benefit in this patient?   (A) Atenolol   (B) Lisinopril   (C) Metoprolol succinate   (D) Propranolol
