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.
