Answer to Question 1

ANS: B
Symptoms include edema of the lower extremities and hyperpigmentation of the skin of the feet and ankles but deep vein thrombi do not form. Edema in these areas may extend to the knees but not above. Gangrene does not occur in veins but in arteries.

Answer to Question 2

ANS: B
The probable cause of the patient's varicose veins is gradual venous distention caused by the ac-tion of gravity on blood in the legs due to long periods of standing. Varicose veins are most like-ly due to long periods of standing leading to the action of gravity promoting venous distention. Exercise would help prevent this. Trauma can occur, but usually this affects the more superficial veins. Ischemia affects arteries not veins.
