Nursing Elites

1. Each is a physiologic role of vitamin D, except one. Which is the exception?

• A. Hematopoiesis
• B. Cardiac and neuromuscular function
• C. Immune responses
• D. Serum calcium regulation

Correct answer: A

Rationale: The correct answer is A, Hematopoiesis. Vitamin D plays a crucial role in regulating serum calcium levels, which is essential for maintaining cardiac and neuromuscular function. Additionally, vitamin D is involved in modulating immune responses. However, hematopoiesis, the formation of red blood cells, is not a direct physiologic role of vitamin D. Therefore, hematopoiesis is the exception among the listed functions of vitamin D.

2. What laboratory value would be considered a high-risk measure for coronary heart disease assessment?

• A. triglycerides > 150 mg/dL
• B. BMI > 31
• C. LDL cholesterol < 128 mg/dL
• D. blood pressure of 128/82 mmHg

Correct answer: B

Rationale: The correct answer is B: BMI > 31. A BMI over 31 is considered a high-risk factor for coronary heart disease as it indicates obesity, which is strongly linked to cardiovascular issues. Triglycerides > 150 mg/dL (choice A) can contribute to heart disease risk but are not as specific as BMI in assessing overall risk. LDL cholesterol < 128 mg/dL (choice C) is actually a desirable level, indicating lower risk. A blood pressure of 128/82 mmHg (choice D) is within normal range and not a high-risk measure specifically for coronary heart disease.

3. A nurse is caring for a client who has a body mass index (BMI) of 30. Four weeks after nutritional counseling, which of the following evaluation findings indicates the plan of care was followed?

• A. BMI of 25
• B. Weight gain of 1.8 kg
• C. BMI of 33
• D. Weight loss of 2.7 kg

Correct answer: D

Rationale: A weight loss of 2.7 kg in four weeks indicates effective adherence to a nutritional plan aimed at reducing body mass index (BMI), moving towards a healthier weight. Choices A, B, and C are incorrect because a decrease in weight, as shown in choice D, is the desired outcome when managing a client with a BMI of 30 to reach a healthier range.

4. Does alcohol contain energy and is therefore a nutrient?

• A. True
• B. False
• C.
• D.

Correct answer: B

Rationale: Alcohol does contain energy and provides calories, but it is not considered a nutrient. Nutrients are substances that contribute to essential bodily functions. While alcohol may have energy, it does not provide essential vitamins, minerals, or other nutrients necessary for the body's health. Additionally, excessive alcohol consumption can have harmful effects on the body, further supporting why alcohol is not classified as a nutrient.

5. Which of the following groups of vitamins are fat-soluble?

• A. vitamins B and C
• B. vitamins A and C
• C. vitamins B, E, K, D
• D. vitamins A, E, K, D

Correct answer: D

Rationale: The correct answer is D: vitamins A, E, K, and D. Fat-soluble vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue. Vitamins B and C are water-soluble vitamins and are not stored in the body; any excess amounts are usually excreted in the urine. Therefore, choices A, B, and C are incorrect.
