PERIPHERAL VASCULAR SYSTEM NURSE 1010 WEEK 6 EXAM
QUESTIONS WITH VERIFIED SOLUTIONS 100% CORRECT
1. What is the primary function of arteries?
A. To drain deoxygenated blood from tissues
B. To store venous blood for later use
C. To supply oxygen and essential nutrients to tissues
D. To transport lymph fluid
Answer: C. Rationale: Arteries carry oxygenated blood from the heart to tissues, ensuring
nutrient delivery and waste removal.*
2. Which artery in the arm is most accessible for examination?
A. Axillary artery
B. Brachial artery
C. Subclavian artery
D. Ulnar artery
Answer: B. Rationale: The brachial artery is palpable in the antecubital fossa and divides into
the radial and ulnar arteries.*
3. Which arteries are accessible for examination in the leg?
A. Carotid and femoral arteries
B. Radial and ulnar arteries
C. Femoral, popliteal, anterior tibial, posterior tibial, dorsalis pedis
D. Iliac and subclavian arteries
Answer: C. Rationale: These are the major leg arteries that can be palpated for peripheral
circulation assessment.*
4. Peripheral Arterial Disease (PAD) primarily affects:
A. Coronary arteries
B. Pulmonary arteries
C. Non-coronary arteries, especially in the limbs
D. Lymphatic vessels
Answer: C. Rationale: PAD refers to atherosclerotic blockages in arteries supplying the
extremities.*

5. How do veins differ from arteries structurally and functionally?
A. Veins are thicker and have higher pressure
B. Veins return deoxygenated blood and have thinner, more distensible walls
C. Veins carry oxygen-rich blood under pressure
D. Veins contain no valves
Answer: B. Rationale: Veins return blood to the heart, have valves to prevent backflow, and lie
closer to the skin.*
6. Why are veins referred to as “capacitance vessels”?
A. They contain muscle fibers
B. They carry nutrients
C. They stretch to accommodate large blood volumes
D. They control blood pressure
Answer: C. Rationale: Veins have the capacity to hold up to 70% of circulating blood volume.*
7. What are the major types of veins in the leg?
A. Coronary and pulmonary veins
B. Deep (femoral/popliteal), superficial (saphenous), perforator veins
C. Jugular and subclavian veins
D. Axillary and cephalic veins
Answer: B. Rationale: These three venous systems facilitate return of blood from the lower
limbs.*
8. What mechanisms help venous blood return to the heart?
A. Gravity and peristalsis
B. Skeletal muscle contraction, pressure gradient from respiration, and valves
C. Osmosis and diffusion
D. Only blood pressure
Answer: B. Rationale: The “muscle pump,” respiratory changes, and valves prevent venous
pooling.*
