,Question 1
A student reviewing cardiac anatomy identifies the valve
located between the right atrium and right ventricle. Which
valve is being described?
A. Mitral valve
B. Aortic valve
C. Tricuspid valve
D. Pulmonic valve
Correct Answer: C
Rationale:
The tricuspid valve is positioned between the right atrium and
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 lies between the
left ventricle and aorta, and the pulmonic valve lies between
the right ventricle and pulmonary artery.

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 flows through the tricuspid valve into the right ventricle.
The left atrium receives oxygenated blood from the lungs.

Question 3
A nurse reviewing blood flow through the heart identifies which
structure receives blood immediately after it passes through
the pulmonic valve?
A. Aorta
B. Left atrium
C. Pulmonary artery
D. Pulmonary veins
Correct Answer: C
, Rationale:
Blood flows from the right ventricle through the pulmonic valve
into the pulmonary artery for transport to the lungs. The
pulmonary veins return oxygenated blood from the lungs to the
left atrium. The aorta carries blood from the left ventricle to
systemic circulation.

Question 4
Which heart valve prevents backflow of blood into the left
ventricle during ventricular relaxation?
A. Tricuspid valve
B. Pulmonic valve
C. Mitral valve
D. Aortic valve
Correct Answer: D
Rationale:
The aortic valve closes during ventricular relaxation to prevent
blood from flowing backward from the aorta into the left
ventricle. The mitral valve separates the left atrium and left
ventricle, while the tricuspid valve separates the right atrium
and right ventricle.
