A nurse is reviewing the medical record of a client who has metabolic acidosis.
The nurse should realize that which of the following findings contributes to the development of metabolic acidosis?

Hyperventilation.

Diarrhea.

Salicylate intoxication.

Vomiting.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Hyperventilation is a compensatory mechanism for metabolic acidosis, not a cause. It helps to eliminate carbon dioxide, a weak acid, to balance the pH.

Choice B rationale:

Diarrhea causes loss of bicarbonate, a base, from the body. This can lead to metabolic acidosis as there is an excess of acids.

Choice C rationale:

Salicylate intoxication can cause both respiratory alkalosis and metabolic acidosis. However, it is not the most common cause of metabolic acidosis.

Choice D rationale:

Vomiting leads to loss of gastric acid, a strong acid. This usually results in metabolic alkalosis, not acidosis.

Correct Answer is D

Explanation

Choice A rationale:

The hepatic portal system does not drain the chest wall and it does not empty into the superior vena cava.

Choice B rationale:

The hepatic portal system is not composed of arteries and it does not supply oxygenated-rich blood to the sex glands.

Choice C rationale:

The hepatic portal system cannot be palpitated in the mid-upper arm in the antecubital space.

Choice D rationale:

The hepatic portal system carries blood from abdominal organs to the liver for processing before returning to the heart.

A. Pulmonary vein. B. Pulmonary artery. C. Aorta. D. Inferior vena cava.

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.
