A nurse is caring for a client who has a pressure injury and is assessing the client's dietary intake. Which of the following factors should the nurse identify as a barrier to wound healing?

Choice A reason: Elevating the head of the client's bed can help prevent aspiration and facilitate swallowing. The nurse should keep the client's head elevated at least 30 degrees during and after feeding, and check for signs of aspiration, such as coughing, choking, or wheezing.

Choice B reason: Using a syringe to give the client fluids is not a safe method, as it can cause the fluids to enter the airway too quickly and cause aspiration. The nurse should use a spoon or a cup to give the client fluids, and thicken them if needed to make them easier to swallow.

Choice C reason: Instructing the client to chew on the left side of their mouth is not a good idea, as the left side is paralyzed and has reduced sensation. The client may not be able to chew or feel the food on that side, and may accidentally bite their tongue or cheek. The nurse should instruct the client to chew on the right side of their mouth, which is unaffected by the stroke.

Choice D reason: Instructing the client to swallow with their head tilted back is not a good practice, as it can open the airway and allow food or liquid to enter the lungs. The nurse should instruct the client to swallow with their head tilted slightly forward, which can close the airway and direct the food or liquid to the esophagus.

Choice C reason: This statement shows that the client has understood the importance of vitamin D and calcium for bone health. Fortified milk, fatty fish, and cheese are good sources of both nutrients, which help to maintain bone density and prevent osteoporosis.

Choice A reason: This statement is incorrect, as vitamin A supplementation can have adverse effects on bone health. Excessive intake of vitamin A can increase the risk of fractures and reduce bone mineral density.

Choice B reason: This statement is partially correct, as calcium supplementation can help to meet the daily requirement of calcium for bone health. However, calcium alone is not enough, as vitamin D is also needed to facilitate the absorption of calcium and prevent its loss from the bones.

Choice D reason: This statement is irrelevant, as none of the foods mentioned are particularly beneficial for bone health. Orange juice, lean meats, and egg whites are good sources of vitamin C, protein, and biotin, respectively, but they do not provide significant amounts of vitamin D or calcium.
