APHY 102 UNIT #2 PRACTICE TEST (SAMPLE 2) MOST TESTED
QUESTIONS AND ANSWERS GRADED A+ WITH RATIONALES
1. The medical term used to describe an abnormally slow heart rate is:
A. Cardioversion
B. Fibrillation
C. Tachycardia
D. Bradycardia
✅Correct Answer: D. Bradycardia
Rationale:
Bradycardia refers to a heart rate below 60 beats per minute in adults. Tachycardia is a fast
heart rate, fibrillation is chaotic electrical activity, and cardioversion is a therapeutic procedure.
2. Blood from the face and scalp is primarily drained by the:
A. Cephalic vein
B. Subclavian vein
C. External jugular vein
D. Inferior vena cava
✅Correct Answer: C. External jugular vein
Rationale:
The external jugular vein drains superficial structures of the head and neck, including the face
and scalp, before emptying into the subclavian vein.
3. Blood pressure in the systemic arteries is greatest during:
A. Ventricular diastole
B. Ventricular systole
C. Atrial systole
D. Atrial diastole
✅Correct Answer: B. Ventricular systole
,ESTUDYR
Rationale:
During ventricular systole, the ventricles contract and eject blood into the arteries, creating the
highest arterial pressure (systolic pressure).
4. The innermost lining of the heart is known as the:
A. Endocardium
B. Myocardium
C. Epicardium
D. Pericardium
✅Correct Answer: A. Endocardium
Rationale:
The endocardium lines the chambers and valves of the heart. The myocardium is the muscular
layer, and the epicardium is the outermost layer.
5. The right atrium receives blood directly from which structures?
A. Superior vena cava, inferior vena cava, and coronary sinus
B. Superior vena cava and inferior vena cava only
C. Coronary veins only
D. Pulmonary veins
✅Correct Answer: A
Rationale:
The right atrium receives deoxygenated blood from systemic circulation via the superior and
inferior vena cava and from the heart muscle via the coronary sinus.
6. The normal pacemaker of the heart is the:
A. Atrioventricular (AV) node
B. Bundle of His
C. Purkinje fibers
D. Sinoatrial (SA) node
✅Correct Answer: D. Sinoatrial node
, ESTUDYR
Rationale:
The SA node initiates electrical impulses that determine heart rate and rhythm.
7. Which artery supplies blood to a large portion of the intestinal tract?
A. Middle sacral artery
B. Lumbar arteries
C. Phrenic arteries
D. Superior mesenteric artery
✅Correct Answer: D
Rationale:
The superior mesenteric artery supplies the small intestine and part of the large intestine.
8. When taking a pulse near the thumb on the wrist, which artery is palpated?
A. Ulnar artery
B. Radial artery
C. Brachial artery
D. Palmar arch arteries
✅Correct Answer: B. Radial artery
Rationale:
The radial artery runs superficially near the wrist and is commonly used for pulse assessment.
9. Which factor is least important in returning blood to the heart?
A. Valves in veins
B. Skeletal muscle pump
C. Arterial pressure pushing blood forward
D. Negative intrathoracic pressure
✅Correct Answer: C
