Nursing Elites

1. Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin E

Correct answer: D

Rationale: Vitamin E is an antioxidant that helps protect eye health and prevent macular degeneration.

2. The PEM in which children ages 18-24 months display edema of the extremities, torso, and face, fatty liver, sparse yellow hair, and receive adequate kilocalories but not enough high-quality proteins is called?

• A. Marasmus
• B. Kwashiorkor
• C. Anemia
• D. Noma

Correct answer: B

Rationale: Kwashiorkor is a form of severe malnutrition characterized by edema, fatty liver, and other symptoms, typically resulting from inadequate protein intake despite adequate calorie intake.

3. What should Mrs. Smith do to increase her HDL levels, as advised by the nurse?

• A. Monitor her blood glucose levels
• B. Quit smoking
• C. Control her blood pressure
• D. Take fish oil supplements

Correct answer: B

Rationale: The correct answer is 'Quit smoking.' Smoking has been shown to lower HDL (High-Density Lipoprotein) levels, and quitting can help to improve these levels. HDL is often referred to as 'good cholesterol' because it helps to remove other forms of cholesterol from the bloodstream, reducing the risk of heart disease. While monitoring blood glucose levels, controlling blood pressure, and taking fish oil supplements can contribute to overall health and wellbeing, they do not directly increase HDL levels in the same way that quitting smoking does. Therefore, quitting smoking is the most effective way for Mrs. Smith to increase her HDL levels as advised by the nurse.

4. What information should a working mother who wants to continue breastfeeding her infant by occasionally pumping milk ahead of time be given to help her successfully maintain breastfeeding?

• A. Breast milk can be refrigerated for up to 4 days
• B. Breast milk stored in a deep freezer can be kept for up to 12 months
• C. Heating breast milk in the microwave can degrade its nutritional quality
• D. Breast milk can be expressed either by hand or with an electric pump

Correct answer: D

Rationale: The correct answer is D. This information is crucial as it informs the mother of her options for expressing milk, which is the first step in being able to store and later feed it to her child while she's away at work. Choice A has been corrected to state that breast milk can be refrigerated for up to 4 days, providing a more accurate storage timeframe. Choice B has been revised to indicate that breast milk stored in a deep freezer can be kept for up to 12 months, aligning with the recommended storage duration. Choice C now highlights that heating breast milk in the microwave can degrade its nutritional quality, emphasizing the importance of using proper methods for warming breast milk and avoiding potential harm to the baby's health and well-being.

5. 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.
