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

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.

2. Clients with type 2 diabetes are most likely to achieve metabolic control if they:

Correct answer: A

Rationale: Weight loss improves insulin sensitivity and glycemic control, making it a key strategy in managing type 2 diabetes.

3. You are teaching your clients the difference between Type I (IDDM) and Type II (NDDM) diabetes. Which of the following statements is true?

Correct answer: D

Rationale: The correct answer is D. Type II diabetes (NIDDM) is characterized by insulin resistance and a relative lack of insulin. It is not primarily characterized by an abnormal immune response. Option A is incorrect because only Type I diabetes clients are prone to developing ketosis due to a lack of insulin. Option B is incorrect because while Type II diabetes is more common and often preventable through lifestyle changes, it is not solely genetic. Option C is incorrect because Type I diabetes, not Type II, is characterized by fasting hyperglycemia due to an absolute lack of insulin production.

4. Loss of smell results in a condition that limits capacity to detect the flavor of food and beverages called:

Correct answer: C

Rationale: Anosmia is the loss of the sense of smell, which significantly impacts the ability to detect flavors in food and beverages.

5. What is the procedure called when direct observations are used to generate an estimate of a client's current food intake?

Correct answer: C

Rationale: A kilocalorie count is the correct answer as it involves directly observing a client's food intake, which is often used in hospitals to accurately assess nutritional intake and ensure it meets dietary requirements. A food diary (Choice A) is typically self-reported by the client and not directly observed. A 24-hour recall (Choice B) is also usually self-reported and relies on a client's memory of the past 24 hours, which can be unreliable. A nutrient surveillance record (Choice D) is a broader term for tracking nutrient intake in a population and is not specific to the direct observation of an individual's food intake.
