Which Condition is Caused by Defective Valves in the Lower

Question

Which condition is caused by defective valves in the lower leg veins?
A) Portal hypertension
B) Varicose veins
C) Absent pedal pulse
D) Ascites

Accepted Answer

Varicose veins are caused by defective valves in the lower leg veins, which leads to blood pooling and increased pressure. This causes the veins to become swollen, twisted, and visible under the skin. A, C, and D are not caused by defective valves in the lower leg veins. Portal hypertension is caused by increased pressure in the portal vein, which carries blood from the digestive organs to the liver. Absent pedal pulses can be a sign of peripheral artery disease. Ascites is the accumulation of fluid in the abdomen, often due to liver disease.
