Write answer in between .Q:A 48-year-old man presents to the emergency department with complaints of substernal chest pain for the past 1 hour. The pain is crushing in nature and radiates to his neck and left arm. He rates the pain as 710. He gives a history of similar episodes in the past that resolved with rest. He is a non-smoker and drinks alcohol occasionally. On physical examination, the temperature is 37.0C 98.6F, the pulse rate is 130min and irregular, the blood pressure is 14892 mm Hg, and the respiratory rate is 18min. The physician immediately orders an electrocardiogram, the findings of which are consistent with an acute Q-wave myocardial infarction MI. After appropriate emergency management, he is admitted to the medical floor. He develops atrial fibrillation on the second day of admission. He is given a β-adrenergic blocking agent for the arrhythmia. On discharge, he is advised to continue the medication for at least 2 years. Which of the following β-adrenergic blocking agents was most likely prescribed to this patient?? A: Acebutolol, B: Celiprolol, C: Atenolol, D: Penbutolol, E: Pindolol,  <response>: This is a clinical vignette describing a 48-year-old man who presents with chest pain and other symptoms consistent with an acute myocardial infarction MI. He subsequently develops atrial fibrillation and is treated with a beta-blocker. The question asks which beta-blocker was most likely prescribed. Key points from the vignette:- 48-year-old male with acute MI complicated by atrial fibrillation- Requires rate control for atrial fibrillation - Beta-blocker therapy recommended for at least 2 years post-MIOf the answer choices provided, atenolol is the most appropriate beta-blocker in this clinical scenario. Atenolol has greater selectivity for beta-1 receptors, making it preferable for conditions like MI where beta-1 blockade is desired. It is also cardioselective and has a longer half-life allowing for once daily dosing. The other agents are less selective or have intrinsic sympathomimetic activity, which is not ideal in this patient.C: Atenolol
