The structure that carries oxygenated blood to the body from the left ventricle is the: a. aorta. b. pulmonary artery. c. pulmonary vein. d. superior vena cava. ANS: A The aorta carries oxygenated blood from the left ventricle to the body. The pulmonary artery carries deoxygenated blood from the right side of the heart to the lungs. The pulmonary vein carries oxygenated blood from the lungs to the left side of the heart. The superior vena cava carries blood from the upper body to the right atrium.

Induration, edema and hyperpigmentation are common associated findings with which of the following? a. Peripheral arterial disease b. Venous ulcer c. Arterial embolic disease d. Venous thrombus ANS: B A venous ulcer also results from chronic venous insufficiency and demonstrates induration edema and hyperpigmentation. Peripheral arterial edema results in ischemia, in which the foot or leg is painful and cold; nonulceration is common as the muscles atrophy. Arterial embolic disease includes occlusion of the small arteries, resulting in blue toe syndrome and splinter hemorrhages in the nail bed. A venous thrombus presents with minimal ankle edema, low-grade fever, tachycardia, and possibly a positive Homan sign.
