,Question 1
A telemetry learner reviews cardiac anatomy before ECG
interpretation. Blood returning from the lungs enters which
heart 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 into the left atrium. The right atrium receives
deoxygenated blood from the systemic circulation. The
ventricles are pumping chambers rather than receiving
chambers.

Question 2
An ECG student is tracing the pathway of blood flow through
the heart. Which valve separates the right atrium from the right
ventricle?

,A. Mitral valve
B. Aortic valve
C. Pulmonic valve
D. Tricuspid valve
Correct Answer: D
Rationale:
The tricuspid valve lies between the right atrium and right
ventricle. The mitral valve separates the left atrium and left
ventricle. The pulmonic and aortic valves are semilunar valves
located at ventricular outflow tracts.

Question 3
A patient’s ECG demonstrates normal sinus rhythm. To
understand cardiac conduction, the nurse reviews the chamber
responsible for pumping oxygenated blood into systemic
circulation. Which chamber performs this function?
A. Right atrium
B. Left atrium
C. Right ventricle
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
During rhythm interpretation, a nursing student reviews
pulmonary circulation. Deoxygenated blood leaves the right
ventricle through which structure?
A. Aorta
B. Pulmonary artery
C. Superior vena cava
D. Pulmonary vein
Correct Answer: B
Rationale:
The pulmonary artery carries deoxygenated blood from the
right ventricle to the lungs. The pulmonary veins return
oxygenated blood to the left atrium. The aorta carries blood
from the left ventricle into systemic circulation.
