Nursing Elites

1. The RDA for iron is higher in premenopausal women than for men or postmenopausal women because of the blood loss during menstruation.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: A

Rationale: Both the statement and the reason are correct and related. The Institute of Medicine (IOM) recommends 18 mg of iron per day for women 19 to 50 years old, 8 mg/day for women 51 years old and older, and men 19 years old and older. During menstruation, women lose blood containing iron, leading to a higher iron requirement in premenopausal women compared to men or postmenopausal women. This increased demand aims to replenish the iron lost during this physiological process. Therefore, the statement and reason are directly linked, explaining why the RDA for iron is higher in premenopausal women than in men or postmenopausal women. Choices B, C, and D are incorrect as they do not accurately assess the relationship between the statement and the reason provided in the question.

2. During the acute phase of a burn, the priority nursing intervention in caring for this client is:

• A. Prevention of infection
• B. Pain management
• C. Prevention of bleeding
• D. Fluid resuscitation

Correct answer: D

Rationale: During the acute phase of a burn, fluid resuscitation is the priority nursing intervention. This phase is characterized by fluid loss and the risk of hypovolemic shock. Administering fluids is crucial to maintain perfusion and prevent complications such as organ failure. While prevention of infection, pain management, and prevention of bleeding are important aspects of burn care, fluid resuscitation takes precedence in the acute phase to stabilize the client's condition and prevent further damage.

3. The major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet.

• A. True
• B. False
• C.
• D.

Correct answer: B

Rationale: It is false that the major determinant of a person's total cholesterol levels is the amount of cholesterol in their diet. While dietary cholesterol can have some impact on total cholesterol levels, it is not the major determinant. The amount and types of fats consumed, particularly saturated and trans fats, have a more significant impact on blood cholesterol levels. Therefore, a diet high in these types of fats can lead to high cholesterol, irrespective of the amount of dietary cholesterol consumed. This is why it is essential to maintain a balanced diet with a limited intake of saturated and trans fats.

4. Which nutrient is most important for wound healing in a patient post-surgery?

• A. Vitamin C
• B. Protein
• C. Iron
• D. Calcium

Correct answer: B

Rationale: Protein is essential for tissue repair and wound healing.

5. Which of the following statements are correct?

• A. Lipids are transported in the blood as lipoproteins, which are clusters of lipids associated with proteins.
• B. In type II diabetes, the pancreas produces insulin, but cells are resistant to this signal.
• C. The glycemic index classifies foods based on their potential to raise blood glucose levels.
• D. All of the above

Correct answer: D

Rationale: Option A is correct because lipoproteins indeed transport lipids in the blood. They are complexes of lipids and proteins that transport water-insoluble lipids through the blood. Option B is correct as it accurately describes the condition of type II diabetes where the pancreas can produce insulin, but the cells are resistant to its signal, causing an ineffective regulation of blood sugar. Option C is also correct because the glycemic index is indeed a classification system for foods based on their potential to raise blood glucose levels. High glycemic index foods raise blood glucose levels faster than low glycemic index foods. Hence, all the statements are correct, making option D the correct answer.
