A 56-year-old man comes to the emergency department complaining of substernal chest pain that radiates to the left shoulder. Electrocardiogram (EKG) demonstrates ST-elevations in leads II, III, and aVF. The patient subsequently underwent catheterization with drug-eluting stent placement with stabilization of his condition. On post-operative day 3, the patient experiences stabbing chest pain that is worse with inspiration, diaphoresis, and general distress. His temperature is 98.7°F (37.1°C), blood pressure is 145/97mmHg, pulse is 110/min, and respirations are 23/min. EKG demonstrates diffuse ST-elevations. What is the best treatment for this patient?
ALisinopril
BSurgery
CNeedle thoracotomy
DAtorvastatin
EAspirin
A patient presents with periods of severe headaches and flushing however every time they have come to the physician they have not experienced any symptoms. The only abnormal finding is a blood pressure of 175 mmHg/100 mmHg. It is determined that the optimal treatment for this patient is surgical. Prior to surgery which of the following noncompetitive inhibitors should be administered?
APhentolamine
BIsoproterenol
CAtropine
DPropranolol
EPhenoxybenzamine
A 60-year-old woman presents to the emergency room with chest pain that started 20 minutes ago while watching television at home. The pain is substernal and squeezing in nature. She rates the pain as 6/10 and admits to having similar pain in the past with exertion. Her past medical history is significant for diabetes mellitus that is controlled with metformin. The physical examination is unremarkable. An electrocardiogram (ECG) shows ST-segment depression in the lateral leads. She is started on aspirin, nitroglycerin, metoprolol, unfractionated heparin, and insulin. She is asked not to take metformin while at the hospital. Three sets of cardiac enzymes are negative. Lab results are given below: Serum glucose 88 mg/dL Sodium 142 mEq/L Potassium 3.9 mEq/L Chloride 101 mEq/L Serum creatinine 1.2 mg/dL Blood urea nitrogen 22 mg/dL Cholesterol, total 170 mg/dL HDL-cholesterol 40 mg/dL LDL-cholesterol 80 mg/dL Triglycerides 170 mg/dL Hematocrit 38% Hemoglobin 13 g/dL Leucocyte count 7,500/mm3 Platelet count 185,000 /mm3 Activated partial thromboplastin time (aPTT) 30 seconds Prothrombin time (PT) 12 seconds Urinalysis Glucose negative Ketones negative Leucocytes negative Nitrites negative Red blood cells (RBC) negative Casts negative An echocardiogram reveals left ventricular wall motion abnormalities. With the pain subsiding, she was admitted and the medications were continued. A coronary angiography is planned in 4 days. In addition to regular blood glucose testing, which of the following should be closely monitored in this patient?
AActivated partial thromboplastin time (aPTT) alone
BProthrombin time alone
CaPTT and platelet count
DPlatelet count alone
EProthrombin time and platelet count
