1. Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C

2. Which of the following is a form of primary prevention?

• A. Regular Check-ups
• B. Regular Screening
• C. Self-Medication
• D. Immunization

Correct answer: D

Rationale: The correct answer is D, 'Immunization.' Primary prevention aims to prevent disease before it occurs by preventing exposure to risk factors. Immunization is a classic example of primary prevention as it helps prevent the development of infectious diseases. Choice A, 'Regular Check-ups,' is more related to secondary prevention by detecting diseases early. Choice B, 'Regular Screening,' is also more aligned with secondary prevention as it involves early detection of diseases. Choice C, 'Self-Medication,' is not a form of primary prevention but rather a risky practice that can lead to adverse outcomes.

3. The small intestine is comprised of the cecum, colon, and rectum. The large intestine includes the duodenum, jejunum, and ileum.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: B

Rationale: Both statements are false. The small intestine consists of the duodenum, jejunum, and ileum, while the large intestine includes the cecum, colon, and rectum.

4. Each nonnutritive sweetener can be recommended to patients with phenylketonuria, except one. Which one is the exception?

• A. Cyclamate
• B. Acesulfame-K
• C. Saccharin
• D. Aspartame

Correct answer: D

Rationale: The correct answer is D, Aspartame. Aspartame contains phenylalanine, which is contraindicated for individuals with phenylketonuria (PKU), a genetic disorder that impairs phenylalanine metabolism. Therefore, patients with PKU should avoid aspartame. Choices A, B, and C (Cyclamate, Acesulfame-K, Saccharin) are considered safe for individuals with PKU as they do not contain phenylalanine and can be recommended as alternatives to sugar for these patients.

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

• A. Food diary
• B. 24-hour recall
• C. Kilocalorie count
• D. Nutrient surveillance record

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.
