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 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.

A. “Try to place the nipple, the areola, and some breast tissue beyond the areola into her mouth." B. "Babies know instinctively how much of the nipple to take into their mouth." C. "You should place your nipple and some of the areola into her mouth." D. "Your baby's mouth is rather small so she will only take part of the nipple."

Correct Answer is A

Explanation

A. For effective breastfeeding, the baby should latch onto not just the nipple but also a significant portion of the areola and some breast tissue beyond it. This helps ensure that the baby gets a good latch, which promotes better milk transfer and reduces nipple pain for the mother.
B. While babies have some instinctual feeding behaviors, a proper latch typically requires guidance and assistance from the mother or nurse. Newborns often need help to achieve a deep latch that includes both the nipple and areola. Relying solely on the baby's instinct may lead to an ineffective latch and potential issues with breastfeeding.
C. While it's important for the baby to take some of the areola into their mouth, for the best latch, the baby should take in a larger portion of the areola and breast tissue. Simply placing the nipple and some of the areola may not be sufficient for a deep and effective latch.
D. Although newborns have small mouths, a proper latch should still involve the nipple and a good portion of the areola. Assuming that the baby will only take part of the nipple can lead to improper latching and potential breastfeeding difficulties.
