1. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?

A. The body can produce sufficient amounts of vitamin D from sunlight.
B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
C. Sunscreen blocks the formation of vitamin D3.
D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.

Correct answer: C

Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.

2. Nutrition therapy for clients with diabetes is based on:

A. low dietary intake of sugars
B. standardized diabetic diet plans
C. each client’s lifestyle and preferences
D. the client’s weight and blood glucose level

Correct answer: C

Rationale: Corrected Rationale: Nutrition therapy for clients with diabetes should be individualized to each client's lifestyle, preferences, and needs. This approach ensures that the dietary plan is sustainable and tailored to the client, leading to better adherence and improved health outcomes. Choices A and B are too general and do not account for individual differences among clients. Choice D, focusing solely on weight and blood glucose levels, overlooks other crucial aspects of a client's overall well-being and dietary requirements in diabetes management.

3. A healthcare professional is preparing to remove a client’s clogged NG tube prior to re-inserting a new tube. Which of the following actions should the healthcare professional take first?

A. Assist the client in blowing their nose.
B. Ask the client to take a deep breath and hold it.
C. Pinch the proximal end of the tube.
D. Disconnect the tube from the suction source.

Correct answer: D

Rationale: Correct Answer: Disconnecting the tube from the suction source is the first step in safely removing a clogged NG tube. This action helps prevent any suction-related complications and ensures a smooth transition when removing the tube. Choice A, assisting the client to blow their nose, is not necessary in this situation. Choice B, asking the client to take a deep breath and hold it, is unrelated to the process of removing a clogged NG tube. Choice C, pinching the proximal end of the tube, should only be done after disconnecting the tube from the suction source to prevent the contents from leaking.

4. What is the main function of dietary fiber in managing cholesterol levels?

A. To reduce absorption of dietary fats
B. To increase cholesterol synthesis
C. To enhance protein digestion
D. To decrease cholesterol absorption

Correct answer: D

Rationale: Dietary fiber helps lower cholesterol levels by binding to bile acids and reducing cholesterol absorption.

5. Proteolytic enzymes are most likely to break down which food type?

A. Carbohydrates
B. Proteins
C. Fats
D. Lipids

Correct answer: B

Rationale: Proteolytic enzymes target proteins for breakdown into amino acids. Carbohydrates are broken down by enzymes like amylase, while fats are broken down by lipase. Lipids, which include fats, are not specifically targeted by proteolytic enzymes.
