A nurse is providing dietary teaching to the parents of a newborn who is being breastfed. The nurse should instruct that the transition to whole milk can occur at which of the following ages?
12 months
10 months
8 months
6 months
The Correct Answer is A
A. The recommendation to introduce whole milk is typically at 12 months of age. By this time, the infant's digestive system is mature enough to handle whole milk, and they have likely begun eating a variety of solid foods. Whole milk provides essential nutrients such as calcium and vitamin D, which are important for the child’s development at this stage.
B. At 10 months, the infant is still primarily reliant on breast milk or formula for their nutritional needs. Introducing whole milk before 12 months is generally not recommended because the infant's digestive system might not be fully developed to handle whole milk, and it may not provide adequate nutrition compared to breast milk or formula.
C. At 8 months, the infant is usually beginning to explore solid foods but is still dependent on breast milk or formula for the majority of their nutrition. Whole milk is not recommended at this age as the infant’s digestive system is not yet mature enough to handle it, and the nutritional needs are best met with breast milk or formula.
D. By 6 months, infants are typically starting to be introduced to solid foods but should continue receiving breast milk or formula as their primary source of nutrition. Whole milk is not recommended at this age as the infant’s kidneys and digestive system are not fully developed to process it.

Correct Answer is A
Explanation
A. Vitamin D is synthesized in the skin in response to exposure to ultraviolet B (UVB) rays from sunlight. When the skin is exposed to sunlight, specifically UVB rays, a chemical reaction occurs that converts 7- dehydrocholesterol (a substance found in the skin) into vitamin D3 (cholecalciferol). This form of vitamin D is then converted into its active form in the liver and kidneys.
B. This is not related to the formation of vitamin D. While vitamin A is important for overall health and vision, it does not play a role in the synthesis of vitamin D. Vitamin D formation is independent of vitamin A levels in the body.
C. This is not a direct trigger for vitamin D formation. While weight-bearing exercise is important for bone health and can improve overall musculoskeletal function, it does not influence the production of vitamin D in the body. The synthesis of vitamin D is primarily influenced by exposure to sunlight.
D. Calcium does not trigger vitamin D formation. While calcium and vitamin D are closely related, with vitamin D being essential for optimal calcium absorption, the presence of calcium does not affect the synthesis of vitamin D. Instead, calcium levels influence how much vitamin D is needed to ensure proper calcium absorption.
Correct Answer is D
Explanation
A. Tempeh is a fermented soybean product, but it's not a reliable source of vitamin B12. While it can contain some vitamin B12, the amount can vary depending on the production process.
B. Sunflower margarine is a plant-based product and does not contain vitamin B12.
C. Sea vegetables can contain some vitamin B12, but the amount is often unreliable and can vary depending on the type of sea vegetable and where it was grown.
D. Algae is the most reliable plant-based source of vitamin B12. It's a common ingredient in many vegan vitamin B12 supplements and fortified foods.
