,Question 1
A student reviewing cardiac anatomy identifies the valve
located between the left atrium and left ventricle. Which valve
is this?
A. Tricuspid valve
B. Pulmonic valve
C. Mitral valve
D. Aortic valve
Correct Answer: C
Rationale:
The mitral valve is located between the left atrium and left
ventricle and prevents backflow into the left atrium during
ventricular contraction. The tricuspid valve is on the right side
of the heart. The pulmonic and aortic valves are semilunar
valves located between ventricles and great vessels.

Question 2
A learner traces blood flow through the heart. Which structure
,receives blood immediately after it leaves the superior and
inferior vena cava?
A. Left atrium
B. Right atrium
C. Right ventricle
D. Pulmonary artery
Correct Answer: B
Rationale:
Deoxygenated blood from the superior and inferior vena cava
enters the right atrium first. Blood then passes through the
tricuspid valve into the right ventricle. The pulmonary artery
carries blood from the right ventricle to the lungs.

Question 3
A patient’s cardiovascular assessment review notes that
oxygenated blood enters the left atrium from which vessels?
A. Pulmonary veins
B. Pulmonary arteries
C. Superior vena cava
D. Coronary arteries
Correct Answer: A
, Rationale:
Pulmonary veins carry oxygenated blood from the lungs to the
left atrium. Pulmonary arteries carry deoxygenated blood to
the lungs. The superior vena cava returns systemic venous
blood to the right atrium. Coronary arteries supply the
myocardium.

Question 4
A nurse reviewing circulation identifies the vessel responsible
for carrying deoxygenated blood from the right ventricle to the
lungs.
A. Aorta
B. Pulmonary vein
C. Pulmonary artery
D. Coronary sinus
Correct Answer: C
Rationale:
The pulmonary artery carries deoxygenated blood from the
right ventricle to the lungs for oxygenation. The aorta carries
oxygenated blood to systemic circulation. Pulmonary veins
return oxygenated blood to the left atrium.
