1. Magnesium's major functions in the body would be least likely to include which of the following?

• A. allowing muscles to relax after contraction
• B. assisting the operation of hundreds of enzymes
• C. synthesis of protein in the soft tissues
• D. regulation of body temperature

Correct answer: D

Rationale: Magnesium plays a key role in muscle relaxation, enzyme operation, and protein synthesis, but it is not directly involved in regulating body temperature.

2. Which vitamin acts most like a hormone?

• A. Vitamin A
• B. Vitamin B
• C. Vitamin D
• D. Vitamin C

Correct answer: C

Rationale: The correct answer is Vitamin D. Although vitamin D, also known as calciferol, has been called a vitamin, it is more appropriately classified as a hormone. Like hormones, vitamin D acts to control the function of other cell types. For example, it helps the body absorb and regulate skeletal calcium and phosphorus levels. Choice A (Vitamin A) plays a crucial role in vision and immune function. Choice B (Vitamin B) is a complex of different vitamins that play various roles in the body. Choice D (Vitamin C) is important for collagen production and acts as an antioxidant.

3. The two members of the health care team who work closely to monitor drug-nutrient interactions are the:

• A. physician and nurse
• B. physician and pharmacist
• C. nurse and clinical dietitian
• D. clinical dietitian and pharmacist

Correct answer: D

Rationale: The correct answer is D: clinical dietitian and pharmacist. Clinical dietitians and pharmacists work closely together to monitor and manage drug-nutrient interactions. While physicians and nurses play essential roles in patient care, they are not typically the primary professionals involved in monitoring drug-nutrient interactions. Therefore, choices A, B, and C are incorrect.

4. Which hormone is produced in fat tissue and helps regulate body fat by suppressing appetite?

• A. glucagon
• B. ghrelin
• C. leptin
• D. insulin

Correct answer: C

Rationale: The correct answer is C, leptin. Leptin is a hormone produced by fat cells that helps regulate energy balance by suppressing hunger, thus aiding in the regulation of body fat. Glucagon (choice A) is a hormone that raises blood glucose levels, ghrelin (choice B) stimulates appetite, and insulin (choice D) regulates blood sugar levels and promotes glucose uptake.

5. A client who was normal weight before pregnancy asks about the recommended weight gain during pregnancy. What should the nurse advise?

• A. 18-40 pounds
• B. 25-35 pounds
• C. 11-20 pounds
• D. 15-25 pounds

Correct answer: B

Rationale: The correct answer is B: 25-35 pounds. According to standard prenatal guidelines, a client with a normal pre-pregnancy weight is recommended to gain between 25-35 pounds during pregnancy. This weight gain is important for the overall health of the mother and the developing baby. Choices A, C, and D are incorrect because they do not fall within the recommended weight gain range for a client with a normal pre-pregnancy weight.
