Answer to Question 1

ANS: A
Intermittent claudication is pain in the leg or foot that becomes worse with exercise and is relieved by rest. The classic signs of peripheral arterial disease include pain, pallor, weak pulse, paresthesias, and palpable coolness. The signs of venous thrombosis are erythema, ropiness, as well as warmth and tenderness along the course of the vein. Edema of the leg and Homan's sign of the foot are also common.

Answer to Question 2

ANS: C
Right ventricular failure is characterized by dependent edema, elevated venous pressure, hepatomegaly, and possibly ascites. Pulmonary embolism presents with sudden shortness of breath and tachycardia. Left ventricular failure is characterized by dyspnea on exertion, cough, fatigue, orthopnea, PND, cardiac enlargement, crackles, gallop rhythm, and pulmonary congestion. Myocardial infarction presents with crushing retrosternal chest pain, pallor, dyspnea, and diaphoresis.
