,Question 1
A telemetry 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 into the right atrium
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 systemic circulation enters which cardiac
chamber 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. The
left atrium receives oxygenated blood from the lungs. The
ventricles receive blood from the atria.

Question 3
A nurse explains that oxygenated blood leaves the lungs and
returns directly to which chamber of the heart?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle
Correct Answer: C
Rationale:
Oxygenated blood travels from the lungs through the
, pulmonary veins into the left atrium. From there, blood passes
through the mitral valve into the left ventricle. The right side of
the heart handles deoxygenated blood.

Question 4
Which structure prevents backflow of blood from the left
ventricle into the left atrium during ventricular contraction?
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.
It closes during ventricular systole to prevent regurgitation into
the left atrium. The tricuspid valve performs the same function
on the right side.
