A nurse is teaching an older adult client about vitamin D deficiency. The nurse should encourage the client to consume an adequate amount of vitamin D to prevent which of the following complications?

Choice A reason: Providing a snack 30 min before treatments can worsen nausea and diarrhea, as food can stimulate gastric motility and secretion. It is better to avoid eating for at least 2 hours before and after treatments.

Choice B reason: Ensuring foods are served hot can increase nausea and diarrhea, as hot foods can have strong smells and irritate the digestive tract. It is better to serve foods at room temperature or cold.

Choice C reason: Administering antiemetics on a schedule can prevent nausea and vomiting, which can lead to dehydration and electrolyte imbalance. Antiemetics can also reduce abdominal cramps and spasms that cause diarrhea.

Choice D reason: Serving low carbohydrate meals can aggravate diarrhea, as carbohydrates are the main source of energy for the body. It is better to serve high carbohydrate meals that are easy to digest, such as rice, potatoes, bread, or crackers.

Choice A reason: Applying ice packs for 15 minutes every hour is not an effective intervention for managing edema following knee replacement surgery because it can impair blood circulation and delay healing. Ice packs can also cause frostbite or nerve damage if applied for too long or too frequently. Ice packs should be used only for the first 24 to 48 hours after surgery and with a cloth barrier between the skin and the ice.

Choice B reason: Elevating the affected leg above the heart level is an effective intervention for managing edema following knee replacement surgery because it can reduce swelling and pain by facilitating venous return and lymphatic drainage. Elevation can also prevent blood clots and infection by improving blood flow and oxygen delivery to the wound site.

Choice C reason: Consuming nutrition-dense foods first is not a relevant intervention for managing edema following knee replacement surgery because it does not directly affect fluid balance or wound healing. Nutrition-dense foods are those that provide high amounts of nutrients per serving, such as eggs, cheese, nuts, beans, and meat. Nutrition-dense foods are important for overall health, but not specifically for edema management.

Choice D reason: Wearing compression stockings during the day is not a recommended intervention for managing edema following knee replacement surgery because it can interfere with wound healing and increase the risk of infection. Compression stockings can also cause skin irritation, blisters, or ulcers if worn incorrectly or too tightly. Compression stockings should be avoided until the wound is fully healed and only used under medical supervision.
