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

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

Question 3
A nurse explains that oxygenated blood leaves the left ventricle
through which structure?
A. Pulmonary artery
B. Superior vena cava
C. Aorta
D. Pulmonary vein
, Correct Answer: C
Rationale:
The left ventricle pumps oxygenated blood into the aorta for
systemic circulation. The pulmonary artery carries
deoxygenated blood from the right ventricle to the lungs.
Pulmonary veins return oxygenated blood to the left atrium.

Question 4
Which valve prevents backflow of blood from the left ventricle
into the left atrium?
A. Tricuspid valve
B. Pulmonic valve
C. Aortic valve
D. Mitral valve
Correct Answer: D
Rationale:
The mitral valve lies between the left atrium and left ventricle
and closes during ventricular contraction to prevent
regurgitation into the left atrium. The aortic valve is positioned
between the left ventricle and aorta.
