A 72-year-old male with an aortic valve area of 0.7 cm² and a mean transvalvular pressure gradient of 52 mm Hg presents for elective hip arthroplasty. What would be included in your plan for this patient?

While on cardiopulmonary bypass, you notice the MAP has dropped from 76 mmHg to 58 mmHg. The perfusionist has administered a phenylephrine bolus without improvement. On examination, the patient’s face appears plethoric with a ruddy red-purple coloration, mild facial edema, and jugular venous distention. The most likely cause is:

You are called to the PACU for a patient who is experiencing chest pain. The nurse reports that the patient did well in surgery and that the only significant medical history is aortic stenosis with a valve area of 0.7 cm². The nurse also reports treating some moderate post-op pain with 4 mg of morphine. You observe the patient’s vital signs on the monitor and note a HR 92, BP 99/53, SpO2 98% on room air. You decide the treatment for the patient’s chest pain is

Heparin produces its anticoagulant effect by:

In a patient with coronary artery disease, coronary blood flow through stenotic segments becomes pressure-dependent when mean arterial pressure falls below:

You are a CRNA giving a break to a colleague who is doing a non-elective emergency case. The colleague tells you the patient came up from the ED with an ischemic bowel. He reports that prior to surgery, all vital signs were normal and lung sounds were clear with a normal heart rhythm and a murmur. The colleague says the patient has been hypotensive in the OR, so he floated a PA catheter. He reports that pulmonary capillary wedge pressures have been 25 mmHg or greater. You believe the hypotension could be from:

A patient with known CAD develops new ST-segment depression in leads V3, V4, and V5 intraoperatively. This pattern most likely reflects ischemia in which coronary artery distribution?

A 68-year-old female with a history of rheumatic fever presents for laminectomy of L3-L5. In reviewing her echocardiogram it shows aortic insufficiency. What would be a primary hemodynamic goal for this patient?
