A nurse is teaching a health class about the heart. Which information from the class members indicates teaching by the nurse is successful for the flow of blood through the heart, starting in the right atrium?

A.

Left atrium, right ventricle, left ventricle

B.

Left atrium, left ventricle, right ventricle

C.

Right ventricle, left atrium, left ventricle

D.

Right ventricle, left ventricle, left atrium

Answer and Explanation

The Correct Answer is A

A. Blood flow starts from the right atrium, moves into the right ventricle, then to the lungs, where it is oxygenated and returns to the left atrium, and then flows into the left ventricle before being pumped into the aorta.  
B. This sequence incorrectly places the left atrium before the right ventricle, which is not the correct flow of blood.  
C. This sequence starts incorrectly with the right ventricle, skipping the left atrium entirely after blood is oxygenated.  
D. This option also incorrectly starts with the right ventricle and does not include the proper sequence of blood flow.
