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?

Exposure to sunlight

Vitamin A depletion

Weight-bearing exercise

Calcium

Answer and Explanation

The Correct Answer is A

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 B

Explanation

A. While iron is crucial for overall health, its primary role in infants is not specifically related to vision development. Iron is essential for many bodily functions, including oxygen transport and brain development, but the statement about vision development is not directly relevant to the primary reasons for iron supplementation in infants.
B. This is a key point to include in the teaching. Iron stores that infants are born with start to deplete around 4-6 months of age. This is why iron-fortified formula or iron-rich complementary foods are recommended to prevent iron deficiency anemia, as breast milk alone may not provide sufficient iron after this period.
C. Iron is important for overall growth and development, including the development of red blood cells and cognitive functions. However, the specific facilitation of bone growth is more directly related to other nutrients like calcium and vitamin D.
D. Iron absorption can be a concern, but this statement is not entirely accurate. Iron in formula is typically well-absorbed, especially in iron-fortified formulas designed for infants. The goal of providing iron-fortified formula is to ensure that the infant receives an adequate amount of iron, which is absorbed effectively to support their growing needs.

A. Discard any residual gastric contents. B. Place the client in low Fowler's position. C. Warm the feeding solution to body temperature. D. Test the pH of gastric aspirate.

Correct Answer is A

Explanation

A. Before administering an enteral feeding, it's important to discard any residual gastric contents to prevent aspiration. Aspirating and discarding the residual helps to assess gastric emptying and ensure that the stomach is able to tolerate the feeding.
B. While placing the client in a semi-Fowler's position is generally recommended during and after enteral feedings to help prevent aspiration, it's not necessary prior to administering the feeding.
C. Warming the feeding solution to body temperature can help to improve the client's comfort and may reduce nausea. However, it's not a critical step before administering the feeding.
D. Testing the pH of gastric aspirate is important to assess for gastric placement and to ensure that the tube is not in the lungs. However, it's typically done prior to the initial placement of the NG tube and is not routinely repeated before each feeding.
