- ADrug induced thrombocytopenia results in mild thrombocytopenia
- BHeparin induced thrombocytopenia results in severe thrombocytopenia with mucocutaneous bleeding
- CDrug induced thrombocytopenia results in significant arterial thrombosis
- DHeparin induced thrombocytopenia results in moderate thrombocytopenia with venous thrombosis

14A 74-year-old man with a past medical history significant for hypertension and coronary artery disease is scheduled for a right thoracotomy for right upper lobectomy. His current medications include aspirin, clopidogrel, lisinopril, and atenolol. A T5-6 thoracic epidural is planned or preoperative analgesia. What is the MINIMUM amount of time the patient should be off his aspirin and clopidogrel prior to having an epidural placed?
- A5 days

- CDecreased blood flow to the brain
- DDecreased myocardial blood flow
18A 35-year-old woman who underwent orthotopic heart transplantation 2 years ago for nonischemic cardiomyopathy presents after a motor vehicle accident for exploratory laparotomy under general anesthesia. Intraoperatively, her blood pressure is 75/35 mmHg and heart rate is 90 bpm. After the administration of phenylephrine, which of the following hemodynamic responses do you MOST expect?
