,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 separates the left atrium from the 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
An ECG-monitored patient is being taught about blood flow
through the heart. Which structure receives blood directly from
the pulmonary veins?
A. Right atrium
B. Right ventricle
,C. Left atrium
D. Left ventricle
Correct Answer: C
Rationale:
Pulmonary veins return oxygenated blood from the lungs to the
left atrium. The right atrium receives deoxygenated blood from
the vena cava. The ventricles pump blood out of the heart
rather than receive blood directly from pulmonary veins.

Question 3
A telemetry patient’s ECG demonstrates normal sinus rhythm.
The nurse understands that effective cardiac output depends
on proper closure of which valves during ventricular systole?
A. Mitral and tricuspid valves
B. Aortic and pulmonic valves
C. Pulmonic and mitral valves
D. Aortic and tricuspid valves
Correct Answer: A
Rationale:
During ventricular systole, the mitral and tricuspid valves close
to prevent regurgitation into the atria. The semilunar valves
, open during systole to allow blood ejection into the pulmonary
artery and aorta.

Question 4
A patient’s ECG shows a regular rhythm at 72 bpm. The nurse
explains that oxygenated blood leaves the left ventricle through
which vessel?
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.
