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.
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.

Correct Answer is C
Explanation
Choice A rationale:
An angle of 60° is not typically used for IM injections. It is more commonly used for subcutaneous injections.
Choice B rationale:
An angle of 45° is also more commonly used for subcutaneous injections, not IM injections.
Choice C rationale:
An angle of 90° is the correct angle for an IM injection into the ventrogluteal muscle. This allows for the needle to penetrate deep into the muscle tissue.
Choice D rationale:
An angle of 75° is not typically used for any type of injection. It could potentially cause injury to the client if used for an IM injection.

Vitamin B12 is a water-soluble vitamin, not a fat-soluble vitamin.
