Question 1
Which heart valve prevents backflow of blood from the left
ventricle into the left atrium during ventricular contraction?
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. It closes during ventricular systole to prevent
regurgitation into the left atrium. The tricuspid valve is on the
right side. The pulmonic and aortic valves are semilunar valves
located at ventricular outflow tracts.

Question 2
Blood returning from the systemic circulation enters the heart
through which structure first?
A. Left atrium
B. Right atrium
C. Left ventricle
D. Pulmonary artery
Correct Answer: B
Rationale:
Deoxygenated blood from the body returns through the
superior and inferior vena cava into the right atrium. It then
moves through the tricuspid valve into the right ventricle. The
left atrium receives blood from the lungs.

, Question 3
A nurse reviewing cardiac blood flow knows oxygenated blood
enters the left atrium from the:
A. Aorta
B. Pulmonary veins
C. Superior vena cava
D. Pulmonary artery
Correct Answer: B
Rationale:
Pulmonary veins return oxygenated blood from the lungs to the
left atrium. The pulmonary artery carries deoxygenated blood
from the right ventricle to the lungs. The vena cava returns
systemic venous blood to the right atrium.

Question 4
Which chamber pumps blood directly into the pulmonary
circulation?
A. Right ventricle
B. Right atrium
C. Left ventricle
D. Left atrium
