<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:Two days after undergoing an uncomplicated total thyroidectomy, a 63-year-old woman has acute, progressive chest pain. The pain is sharp and burning. She feels nauseated and short of breath. The patient has a history of hypertension, type 1 diabetes mellitus, medullary thyroid cancer, multiple endocrine neoplasia type 2A, anxiety, coronary artery disease, and gastroesophageal reflux disease. She smoked half a pack of cigarettes daily for 24 years but quit 18 years ago. Current medications include lisinopril, insulin glargine, insulin aspart, sertraline, aspirin, ranitidine, and levothyroxine. She appears anxious and diaphoretic. Her temperature is 37.4C 99.3F, pulse is 64min, respirations are 17min, and blood pressure is 14877 mm Hg. The lungs are clear to auscultation. Examination shows a 3-cm linear incision over the anterior neck with 1 mm of surrounding erythema and mild serous discharge. The chest wall and abdomen are nontender. There is 55 strength in all extremities and decreased sensation to soft touch on the feet bilaterally. The remainder of the examination shows no abnormalities. Which of the following is the most appropriate next step in management?? A: Obtain an ECG and troponin T levels, B: Administer IV pantoprazole and schedule endoscopy, C: Discontinue levothyroxine and obtain fT4 levels, D: Administer IV levofloxacin and obtain chest radiograph, E: Obtain urine and plasma metanephrine levels,  <response>: This is a clinical vignette describing a patient with acute chest pain 2 days after thyroidectomy surgery. She has a history of multiple medical conditions including hypertension, diabetes, thyroid cancer, coronary artery disease, and GERD. The description of the chest pain as acute, progressive, sharp and burning along with associated symptoms of nausea, shortness of breath, anxiety and diaphoresis are concerning for a cardiac cause, such as myocardial infarction or unstable angina. The history of coronary artery disease further increases this suspicion. The thyroidectomy and levothyroxine therapy raise concern for possible thyroid storm, however the vital signs and lack of fever make this less likely. Gastroesophageal causes are possible but less likely given the character of the pain. Infection is unlikely this early after surgery without fever or abnormal lung exam. Metanephrine levels would be indicated for adrenal causes of hypertension but are not relevant to the acute chest pain.A: Obtain an ECG and troponin T levels
