Question 1
A cardiac monitoring learner reviews a diagram of the heart
and identifies the valve located between the right atrium and
right ventricle. Which valve is being identified?
A. Mitral valve B. Aortic valve C. Tricuspid valve D. Pulmonic
valve
Correct Answer: C
,Rationale: The tricuspid valve is located between the right
atrium and right ventricle and prevents backflow of blood into
the right atrium 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 is located between the right ventricle and
pulmonary artery.

Question 2
A patient’s cardiovascular anatomy review shows blood
returning from the lungs into the left atrium. Which vessel
carries this oxygenated blood?
A. Pulmonary artery B. Superior vena cava C. Inferior vena cava
D. Pulmonary veins
Correct Answer: D
Rationale: Pulmonary veins carry oxygenated blood from the
lungs to the left atrium. The pulmonary artery carries
deoxygenated blood from the right ventricle to the lungs. The
superior and inferior vena cava return deoxygenated blood
from the body to the right atrium.

, Question 3
An ECG learner studying circulation identifies the chamber
responsible for pumping oxygenated blood into the systemic
circulation. Which chamber performs this function?
A. Right atrium B. Right ventricle C. Left atrium D. Left ventricle
Correct Answer: D
Rationale: The left ventricle pumps oxygenated blood through
the aorta into systemic circulation. The right ventricle pumps
blood to the lungs. The atria primarily receive blood returning
to the heart.

Question 4
A telemetry student reviews normal blood flow through the
heart. Which sequence correctly describes blood flow after
blood leaves the right ventricle?
A. Aorta → lungs → left atrium B. Pulmonary artery → lungs →
pulmonary veins C. Superior vena cava → lungs → left ventricle
D. Pulmonary veins → lungs → left atrium
Correct Answer: B
