Correct Answer: A

Rationale: The correct answer is to avoid chocolate and cheese. MAO inhibitors can interact with tyramine-rich foods like these, potentially leading to severe hypertension. Choices B, C, and D are incorrect because taking frequent naps, taking the medication with milk, and avoiding walking without assistance are not relevant precautions associated with MAO inhibitors.

Correct Answer: C

Rationale: The correct answer is C, 'Chicken.' Heme iron from animal sources, such as chicken, is more easily absorbed by the body compared to non-heme iron from plant sources like spinach, dried apricots, and lentils. While plant-based iron sources are beneficial, they are not as readily absorbed by the body as heme iron from animal products.

Correct Answer: D

Rationale: Skim milk is a reliable source of Vitamin B12, which is essential for the health of both the mother and the developing fetus. While figs, broccoli, and stewed tomatoes are nutritious foods, they are not significant sources of Vitamin B12. Figs are a good source of fiber and other vitamins, broccoli is rich in Vitamin C and K, and stewed tomatoes are high in Vitamin C and antioxidants, but they do not contain Vitamin B12 as much as skim milk does.

Correct Answer: C

Rationale: Performing frequent oral care with a tooth sponge is the most appropriate nursing measure to provide comfort to a client with a nasogastric tube draining bile-colored liquids. This measure helps to maintain oral hygiene, prevent dryness, and enhance overall comfort. Allowing the client to suck on ice chips may not address oral hygiene needs, providing mints focuses more on breath freshness rather than comfort, and swabbing the mouth with glycerin swabs may not effectively address oral care needs.

Correct Answer: B

Rationale: The correct answer is B. Pale mucosa of the eyelids and lips is a classic sign of anemia in infants, indicating a lack of sufficient red blood cells. This finding is due to decreased hemoglobin levels, which causes reduced oxygen delivery to tissues. Choices A, C, and D are less specific to anemia in infants. While a hemoglobin level of 12 g/dL may be within the normal range for a 10-month-old infant, the presence of pale mucosa is a more indicative sign of anemia.
