Question 1
Blood returning from the systemic circulation enters the right
atrium and then passes through which valve before reaching
the right ventricle?
A. Aortic valve
B. Pulmonic valve
C. Tricuspid valve
D. Mitral valve
,Correct Answer: C
Rationale:
In normal cardiac blood flow, deoxygenated blood returns to
the right atrium through the venae cavae. It then passes
through the tricuspid valve into the right ventricle. The aortic
valve leads from the left ventricle to the aorta, the pulmonic
valve leads from the right ventricle to the pulmonary artery,
and the mitral valve separates the left atrium from the left
ventricle. Correct identification requires understanding of
sequential chamber-to-valve relationships.

Question 2
Which heart valve prevents backflow of blood from the left
ventricle into the left atrium during ventricular systole?
A. Pulmonic valve
B. Mitral valve
C. Tricuspid valve
D. Aortic valve
Correct Answer: B
Rationale:
The mitral valve lies between the left atrium and left ventricle.
When the ventricle contracts, this valve closes to prevent
, regurgitation into the atrium. The tricuspid valve performs the
same function on the right side. The semilunar valves (aortic
and pulmonic) prevent backflow from arteries into ventricles,
not from ventricle to atrium.

Question 3
A nurse tracing blood flow notes that blood leaves the right
ventricle and travels to the lungs through which structure?
A. Aorta
B. Pulmonary veins
C. Pulmonary artery
D. Coronary sinus
Correct Answer: C
Rationale:
The right ventricle pumps deoxygenated blood through the
pulmonic valve into the pulmonary artery, which carries blood
to the lungs for oxygenation. The pulmonary veins return
oxygenated blood to the left atrium. The aorta carries
oxygenated blood from the left ventricle to systemic
circulation. The coronary sinus drains venous blood from the
myocardium.
