1. 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.

2. You notice that Miss Kate, a bread vendor, receives and changes money, then holds the bread without washing her hands. As a nurse, what should you say to Miss Kate?

A. Miss, don't touch the bread, I'll be the one to pick it up.
B. Miss, please wash your hands before you pick up the bread.
C. Miss, use a pick-up forceps when picking up the bread.
D. Miss, your hands are dirty, I guess I'll try another bread shop.

Correct answer: B

Rationale: The correct answer is B, as it emphasizes the importance of hygiene in food handling, which is crucial to prevent the spread of germs and diseases. The other options do not address the root of the issue, which is the unhygienic handling of food. Option A avoids direct confrontation but does not educate the vendor on proper hygiene. Option C, although it suggests a hygienic method, may not be practical or available in all situations. Option D is an avoidance strategy rather than a way to address the problem.

3. A nurse is initiating continuous enteral feedings for a client who has a new gastrostomy tube. Which of the following actions should the nurse take?

A. Measure the client’s gastric residual every 12 hours.
B. Obtain the client’s electrolyte levels every 4 hours.
C. Keep the client’s head elevated at 15° during feedings.
D. Flush the client’s tube with 30 mL of water every 4 hours.

Correct answer: D

Rationale: Flushing the client’s tube with 30 mL of water every 4 hours is essential to maintain tube patency and prevent blockages. This action helps ensure the continuous flow of enteral feedings without obstruction. Measuring the client’s gastric residual every 12 hours (Choice A) is important but not the priority when initiating enteral feedings. Obtaining the client’s electrolyte levels every 4 hours (Choice B) is unnecessary and not directly related to tube feeding initiation. Keeping the client’s head elevated at 15° during feedings (Choice C) is a good practice to prevent aspiration, but tube flushing is more crucial to prevent tube occlusion.

4. Monosaccharides are converted into glucose in the liver to provide an energy supply to the cells.

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: A

Rationale: Both statements are true. Monosaccharides are indeed converted into glucose in the liver. Glucose, in turn, serves as a primary energy source for cells in the body, providing the necessary fuel for various cellular functions. The liver plays a crucial role in regulating blood glucose levels by converting monosaccharides into glucose and releasing it into the bloodstream when needed. Therefore, option A is the correct choice. Options B, C, and D are incorrect because both statements are accurate in this context.

5. AIDS enteropathy is most commonly manifested as _____.

A. abdominal pain and rectal bleeding
B. diarrhea and weight loss
C. abdominal bloating and flatulence
D. rectal fissures and constipation

While abdominal pain and rectal bleeding (Choice A), abdominal bloating and flatulence (Choice C), and rectal fissures and constipation (Choice D) can occur in some cases, the most common manifestations are diarrhea and weight loss.
