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. Which of the following amino acids are considered indispensable?

• A. Lysine
• B. Methionine
• C. Tryptophan
• D. Valine

Correct answer: A

Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.

3. Commonly known as “shabu” is:

• A. Cannabis Sativa
• B. Lysergic acid diethylamide
• C. Methylenedioxy methamphetamine
• D. Methampetamine hydrochloride

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. A nurse is teaching about nutrition to a client who has a new diagnosis of chronic kidney disease. Which of the following recommendations should the nurse include in the teaching?

• A. Increase phosphorus intake
• B. Limit calcium intake
• C. Limit protein intake
• D. Increase potassium intake

Correct answer: C

Rationale: The correct recommendation for a client with chronic kidney disease is to limit protein intake. Excessive protein consumption can strain the kidneys as they work to eliminate waste products from protein metabolism. This can worsen kidney function in individuals with chronic kidney disease. Therefore, limiting protein intake is crucial in managing this condition. Choices A, B, and D are incorrect. Increasing phosphorus intake can be harmful in kidney disease as it can lead to mineral imbalances. Limiting calcium intake is not typically necessary unless the client has specific complications. Increasing potassium intake may also be inappropriate as potassium levels can be affected in kidney disease.

5. What dietary strategy would most likely be used as part of lifestyle management to reduce the risk of coronary heart disease?

• A. Avoid foods that contain polyunsaturated fat
• B. Limit saturated fat to less than 10 percent of total calories
• C. Limit alcohol intake to one drink daily for women and two drinks daily for men
• D. Avoid consumption of fish and shellfish

Correct answer: C

Rationale: Limiting alcohol intake is part of a strategy to reduce the risk of coronary heart disease by avoiding the negative cardiovascular effects associated with excessive alcohol consumption.
