Default Repeated USMLE Question 40

A 68 year old man presents to his physician complaining of progressive shortness of breath for the last three months. Last week, he started feeling shortness of breath during sleep. He had to wake up at least twice every night and open the window to be able to catch his breath. The patient has a long history of hypercholesterolemia and recurrent angina. On examination, there is pitting edema on both legs.

What of the following expected to be increased in this patient?

A- Cardiac output

B- Peripheral resistance

C- Renal perfusion

D- Lung compliance

Question indicates Congestive Cardiac Failure, so there is a decrease in cardiac output which leads to increase in TRP.
