A patient with CAD is asking the nurse about the mechanisms of the heart.
It would be appropriate for the nurse to respond that when the left ventricle contracts, it pushes blood through the semilunar valve to the:

Pulmonary vein.

Pulmonary artery.

Aorta.

Inferior vena cava.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

This statement is incorrect because the pulmonary vein carries oxygenated blood from the lungs to the left atrium, not from the left ventricle.

Choice B rationale:

This statement is incorrect because the pulmonary artery carries deoxygenated blood from the right ventricle to the lungs, not from the left ventricle.

Choice C rationale:

This statement is correct. When the left ventricle contracts, it pushes blood through the aortic semilunar valve into the aorta, the largest artery in the body.

Choice D rationale:

This statement is incorrect because the inferior vena cava carries deoxygenated blood from the lower half of the body to the right atrium, not from the left ventricle.
