Nursing Elites

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. Saturated fats are generally found in animal products with a few exceptions. Which of the following is a plant product that contains a large proportion of saturated fat?

• A. canola oil
• B. olive oil
• C. soybean oil
• D. coconut oil

Correct answer: D

Rationale: Coconut oil is a plant-based oil that is high in saturated fat, unlike most other plant oils, which are typically unsaturated.

3. During which stage of life is it most critical to build bone mass to prevent osteoporosis?

• A. Infancy
• B. Early childhood
• C. Adolescence
• D. Young adulthood

Correct answer: C

Rationale: Adolescence is the most critical stage for building bone mass, which plays a significant role in preventing osteoporosis in later life. During adolescence, approximately 45% of adult bone mass is formed. Although bone mass can be built during infancy, early childhood, and young adulthood, it is not as significant as during adolescence, making choices A, B, and D incorrect. Therefore, focusing on adequate nutrition and physical activity during adolescence is vital for long-term bone health.

4. A child with ear problem should be assessed for the following, EXCEPT:

• A. is there any fever?
• B. Ear discharge
• C. If discharge is present for how long?
• D. Ear pain

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

5. A nurse at a provider's office is providing teaching to a client who is taking chemotherapy and losing weight. Which of the following should the nurse recommend to increase calorie and protein intake? (Select one that does not apply.)

• A. Top yogurt with fruits.
• B. Add cream to soups.
• C. Use milk instead of water in recipes.
• D. Increase fluids during meals.

Correct answer: D

Rationale: The correct recommendation to increase calorie and protein intake for a client taking chemotherapy and losing weight is to add cream to soups (choice B), as it provides additional calories and proteins. Using milk instead of water in recipes (choice C) can also increase the calorie and protein content. Topping yogurt with fruits (choice A) can be a healthy choice but may not significantly increase calorie and protein intake. Increasing fluids during meals (choice D) may fill up the stomach, potentially reducing the intake of solid foods, which is not ideal when trying to increase calorie and protein consumption.
