,Question 1
A nurse reviewing cardiac anatomy explains that the structure
separating the left atrium from the left ventricle is which valve?
A. Tricuspid valve
B. Pulmonic valve
C. Mitral valve
D. Aortic valve
Correct Answer: C
Rationale:
The mitral (bicuspid) valve separates the left atrium from the
left ventricle and prevents backflow of blood into the left
atrium during ventricular contraction. The tricuspid valve is
located between the right atrium and right ventricle. The
pulmonic valve lies between the right ventricle and pulmonary
artery, and the aortic valve separates the left ventricle from the
aorta.

Question 2
A patient’s blood is traveling from the right ventricle toward
the lungs. Through which valve will the blood pass?
,A. Mitral valve
B. Aortic valve
C. Pulmonic valve
D. Tricuspid valve
Correct Answer: C
Rationale:
Blood leaving the right ventricle enters the pulmonary artery
through the pulmonic valve. The mitral and tricuspid valves are
atrioventricular valves, and the aortic valve allows blood to
leave the left ventricle.

Question 3
Which sequence correctly describes blood flow through the
heart after blood enters the right atrium?
A. Right atrium → left ventricle → pulmonary artery → lungs
B. Right atrium → right ventricle → pulmonary artery → lungs
C. Right atrium → left atrium → lungs → right ventricle
D. Right atrium → aorta → lungs → left atrium
Correct Answer: B
Rationale:
Deoxygenated blood flows from the right atrium to the right
, ventricle, then through the pulmonic valve into the pulmonary
artery and lungs for oxygenation.

Question 4
Oxygenated blood returning from the lungs enters which
chamber first?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
Correct Answer: C
Rationale:
Oxygenated blood returns from the lungs through the
pulmonary veins and enters the left atrium before moving into
the left ventricle.
