Correct Answer is C

Explanation

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.

A. Apply a warm pack. B. Remove the stinger by scraping it off with a knife blade. C. Apply a tourniquet. D. Suck the wound.

Choice B rationale:

Removing the stinger by scraping it off with a knife blade can help to reduce the amount of venom that is released into the body.

Choice C rationale:

Applying a tourniquet can restrict blood flow and cause more harm than good.

Choice D rationale:

Sucking the wound can introduce bacteria and cause infection, so it is not recommended.
