1. Which vitamin is primarily obtained from sunlight exposure?

A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin E

Correct answer: C

Rationale: The correct answer is Vitamin D. Vitamin D is synthesized in the skin when it is exposed to sunlight. This process allows the body to produce Vitamin D naturally. Vitamin A (Choice A) is found in foods like liver and carrots and is not primarily obtained from sunlight. Vitamin C (Choice B) is commonly found in fruits and vegetables. Vitamin E (Choice D) is present in foods like nuts and seeds and is not primarily obtained from sunlight.

2. What instruction should the nurse include on weight gain during pregnancy?

A. Failure to obtain the required weight gain during pregnancy will increase the risk of preterm birth.
B. An obese client needs to gain as much weight as a client with a normal body mass index.
C. A client with a normal body mass index should plan on gaining 50 pounds.
D. Clients will need to eat for two when they are pregnant.

Correct answer: A

Rationale: Appropriate weight gain is crucial for reducing the risk of preterm birth.

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. Which of the following is not a desirable blood lipid value?

A. low total cholesterol
B. high LDL
C. high HDL
D. low blood triglycerides

Correct answer: B

Rationale: The correct answer is B. High levels of LDL (low-density lipoprotein) cholesterol are undesirable as they are associated with an increased risk of cardiovascular disease. Therefore, low total cholesterol (choice A), high HDL (choice C), and low blood triglycerides (choice D) are considered desirable blood lipid values. Low total cholesterol is beneficial as high levels can increase the risk of heart disease. High HDL cholesterol is considered good as it helps remove LDL cholesterol from the arteries. Low blood triglycerides are also preferred as high levels are associated with an increased risk of heart disease.
