1. An estimated _____ percent of persons in the United States who have HIV infection are unaware that they are infected.

Correct answer: B

Rationale: The correct answer is B: '21%'. Approximately 21% of persons in the United States who have HIV infection are unaware that they are infected. This percentage represents a significant portion of individuals who are not aware of their HIV status, highlighting the importance of increased testing and awareness campaigns. Choices A, C, and D are incorrect as they do not align with the estimated percentage provided in the context.

2. Reducing the amount of trans fat in the diet is an effective method of decreasing the risk of CHD. Which food is most likely a source of trans fat?

Correct answer: D

Rationale: The correct answer is D: potato chips. Potato chips, especially when fried in hydrogenated oils, are a common source of trans fats, which are linked to an increased risk of coronary heart disease (CHD). Hot dogs (choice A) can also contain trans fats if made with processed meats and added fats. Whole milk (choice B) and fatty fish (choice C) do not typically contain trans fats, making them less likely sources compared to potato chips.

3. The nurse’s most unique tool in working with the emotionally ill client is his/her

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

4. After cleaning the abrasions and applying antiseptic, the nurse applies a cold compress to the swollen ankle as ordered by the physician. This statement shows that the nurse has a correct understanding of the use of a cold compress:

Correct answer: C

Rationale: The correct understanding of using a cold compress includes knowing that it helps prevent edema and reduces pain. Cold application constricts blood vessels, reducing blood flow to the area, which helps decrease swelling and pain. Choices A, B, and D are incorrect because cold compresses do not directly affect blood viscosity, safety compared to hot compresses, or eliminate toxic waste products due to vasodilation. It is essential for nurses to have a clear understanding of the rationale behind interventions to provide effective patient care.

5. A nurse is instructing the mother of a toddler who has iron-deficiency anemia to increase iron in the child's diet in addition to the prescribed iron supplement. Which of the following foods should the nurse recommend?

Correct answer: C

Rationale: Tuna fish is a good source of iron and would be beneficial for a toddler with iron-deficiency anemia. Skim milk, bananas, and cucumbers are not significant sources of iron and would not help in increasing the iron levels in the child's diet. Skim milk, in particular, can inhibit iron absorption due to its calcium content, which is important for the nurse to educate the mother about.
