1. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?

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. A nurse is caring for a 30-month-old toddler and is preparing a nutritional snack. Which of the following foods is appropriate for the nurse to offer the toddler?
