A nurse is instructing a group of clients about nutrition. The nurse should include that which of the following is a trigger for the formation of vitamin D in the body?
Correct answer
A
Rationale
The correct answer is A: Exposure to sunlight. When the skin is exposed to sunlight, it triggers the formation of a precursor molecule that eventually becomes vitamin D in the body. Sunlight helps convert cholesterol in the skin into vitamin D. Vitamin A depletion (choice B) does not directly trigger the formation of vitamin D. Weight-bearing exercise (choice C) and calcium (choice D) are important for bone health but do not directly trigger the formation of vitamin D.
