Nursing Elites

1. 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.

2. 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.

3. All of the following are electrolytes except:

• A. chloride
• B. potassium
• C. sodium
• D. iron

Correct answer: D

Rationale: Iron is not an electrolyte; electrolytes like sodium, potassium, and chloride help maintain fluid balance and are critical for nerve and muscle function.

4. Riboflavin

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin B12

Correct answer: B

Rationale: Riboflavin is also known as Vitamin B2, which is important for energy production and the metabolism of fats, drugs, and steroids.

5. A nurse is planning a menu for a client with a folic acid deficiency anemia. Which food should the nurse recommend that is high in folate?

• A. 4 slices of roast beef
• B. ½ cup of asparagus
• C. 1 cup part-skim mozzarella cheese
• D. ¼ cup of olives

Correct answer: B

Rationale: The correct answer is B: ½ cup of asparagus. Asparagus is high in folate, making it a suitable recommendation for clients with folic acid deficiency anemia. Folate is essential in the production of red blood cells, which is crucial in managing anemia. Choices A, C, and D do not contain as much folate as asparagus and are not the best options for addressing a folic acid deficiency anemia.
