Nursing Elites

1. Studies suggest that leukoplakia is resolved by excess vitamin A (a fat-soluble vitamin), retinoids, and beta-carotene. Leukoplakia is a white plaque that forms on oral mucous membranes.

• 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. Studies suggest that leukoplakia, a white plaque that forms on oral mucous membranes, can be resolved by vitamin A, retinoids, and beta-carotene. Despite the potential to resolve leukoplakia, relapse is common. Also pertinent, evidence does not indicate that any of these nutrients prevent malignant transformation. The extract provided clarifies that leukoplakia is a white plaque, not an erythematous lesion, and that vitamin A, retinoids, and beta-carotene can help resolve it.

2. Each is a physiologic role of vitamin D, except one. Which is the exception?

• A. Hematopoiesis
• B. Cardiac and neuromuscular function
• C. Immune responses
• D. Serum calcium regulation

Correct answer: A

Rationale: The correct answer is A, Hematopoiesis. Vitamin D plays a crucial role in regulating serum calcium levels, which is essential for maintaining cardiac and neuromuscular function. Additionally, vitamin D is involved in modulating immune responses. However, hematopoiesis, the formation of red blood cells, is not a direct physiologic role of vitamin D. Therefore, hematopoiesis is the exception among the listed functions of vitamin D.

3. While on Bryant’s traction, which of these observations of Graciela and her traction apparatus would indicate a decrease in the effectiveness of her traction?

• A. Graciela’s buttocks are resting on the bed.
• B. The traction weights are hanging 10 inches above the floor.
• C. Graciela’s legs are suspended at a 90 degree angle to her trunk.
• D. The traction ropes move freely through the pulley.

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

4. A nurse is teaching a group of clients who are at risk for heart disease about decreasing saturated fats in their diet. Which of the following fats should the nurse recommend the clients use when cooking?

• A. Palm oil
• B. Peanut oil
• C. Canola oil
• D. Stick margarine

Correct answer: C

Rationale: Canola oil is lower in saturated fats compared to palm oil, peanut oil, and stick margarine, making it a healthier option for clients at risk for heart disease. Palm oil is high in saturated fats, peanut oil has a moderate amount of saturated fats, and stick margarine is also high in saturated fats and trans fats, which are not heart-healthy choices.

5. A nurse is providing teaching to the parent of a toddler about appropriate snacks. Which of the following foods should the nurse include?

• A. Sliced bananas
• B. Raw celery
• C. Peanut butter
• D. Grapes

Correct answer: A

Rationale: The correct answer is sliced bananas. Bananas are a good choice for toddlers as they are easy to chew, rich in potassium, and generally well-tolerated. Raw celery (Choice B) may pose a choking hazard due to its fibrous nature. Peanut butter (Choice C) should be avoided as it can also be a choking hazard and may cause an allergic reaction in some children. Grapes (Choice D) are a choking hazard for toddlers due to their size and shape, so they should be cut into smaller pieces or avoided altogether.
