Nursing Elites

1. A nurse is teaching a client who needs to increase their daily fluid intake. Which of the following foods has the highest percentage of water by weight?

• A. Yogurt
• B. Milk
• C. Lettuce
• D. Honey

Correct answer: C

Rationale: The correct answer is Lettuce. Lettuce has the highest percentage of water by weight among the options provided, making it an excellent choice to increase fluid intake. Yogurt and milk have some water content but are not as high in water percentage as lettuce. Honey, on the other hand, contains very little water and is not a good choice for increasing fluid intake.

2. What physiological role does phosphorus play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction, and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: D

Rationale: The correct answer is D. Phosphorus plays a crucial role in ATP energy release, the metabolism of fats, carbohydrates, and proteins, and regulation of acid-base balance. Choices A, B, and C are incorrect. Phosphorus is not directly involved in blood clotting, transmission of nerve impulses, muscle contraction, or calcium homeostasis. It also has known metabolic functions and is not associated with caries prevention.

3. A diet high in which nutrient can lead to increased risk of developing kidney stones?

• A. Fiber
• B. Protein
• C. Carbohydrates
• D. Unsaturated fats

Correct answer: B

Rationale: High protein intake can increase the risk of kidney stones due to elevated calcium excretion.

4. Select all that apply. To lower LDL levels, you should:

• A. consume minimal amounts of hydrogenated and saturated fats
• B. consume more insoluble fibers than soluble fibers
• C. consume alcohol in moderate levels
• D. engage in regular physical activity

Correct answer: A

Rationale: To lower LDL levels, reducing intake of hydrogenated (trans) and saturated fats is crucial, as these types of fats can raise LDL cholesterol in the blood. Choice B is incorrect because both soluble and insoluble fibers can help lower LDL levels. Choice C is incorrect as excessive alcohol consumption can lead to increased LDL levels. Choice D, engaging in regular physical activity, can help raise HDL (good) cholesterol levels but is not directly related to lowering LDL levels.

5. Which mineral is essential for wound healing?

• A. iodine
• B. chromium
• C. zinc
• D. sulfate

Correct answer: C

Rationale: Zinc plays a critical role in wound healing due to its involvement in cell proliferation, immune function, and protein synthesis, all of which are essential for tissue repair.
