,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 between the left atrium
and left ventricle. The aortic valve is located between the left
,ventricle and aorta. The pulmonic valve lies between the right
ventricle and pulmonary artery.

Question 2
Blood returning from the systemic circulation first enters which
chamber of the heart?
A. Left atrium
B. Right atrium
C. Left ventricle
D. Right ventricle
Correct Answer: B
Rationale:
Venous blood from the body returns through the superior and
inferior vena cava into the right atrium. From there, blood
flows through the tricuspid valve into the right ventricle. The
left side of the heart 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.
The superior vena cava returns deoxygenated blood to the right
atrium.

Question 4
Which structure prevents backflow of blood from the left
ventricle into the left atrium during ventricular contraction?
A. Pulmonic valve
B. Tricuspid valve
