ASPT ASPT Anatomy & Physiology for Phlebotomy 2 — Questions and Answers
Question 1: Which artery runs along the thumb side of the wrist and must be avoided during venipuncture?
- Ulnar artery
- Brachial artery
- Radial artery (Correct answer)
- Femoral artery

The radial artery runs along the thumb (lateral) side of the wrist and must be avoided to prevent arterial puncture complications.
Question 2: What term describes the collapse of a vein during blood collection?
- Phlebitis
- Sclerosis
- Hemolysis
- Collapsed vein (Correct answer)
Correct answer: Collapsed vein
A vein collapses when excessive vacuum or suction causes the vein walls to cave inward, stopping blood flow into the collection tube.
Question 3: Leukocytes are classified into which two major categories?
- Granulocytes and agranulocytes (Correct answer)
- Erythrocytes and thrombocytes
- Monocytes and lymphocytes only
- Basophils and eosinophils only
Correct answer: Granulocytes and agranulocytes
White blood cells (leukocytes) are divided into granulocytes (neutrophils, eosinophils, basophils) and agranulocytes (monocytes, lymphocytes).
Question 4: Which vessel carries deoxygenated blood from the body back to the right side of the heart?
- Aorta
- Pulmonary artery
- Superior and inferior vena cava (Correct answer)

- Dorsal venous network (Correct answer)
- Femoral vein
- Saphenous vein
- Jugular vein
Correct answer: Dorsal venous network
The dorsal venous network is the network of superficial veins on the back (dorsum) of the hand, often used as an alternative venipuncture site.
Question 6: Which blood type is considered the universal donor for red blood cells?
- Type AB positive
