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 Areason: Graham crackers are made from wheat flour, which contains gluten. Peanut butter is a good source of fat and protein, but it may also contain traces of gluten from cross-contamination.

Choice Breason: Poached eggs are a good source of protein, but wheat bagel contains gluten, which is a protein found in wheat, barley, and rye. Gluten can damage the small intestine and cause malabsorption, diarrhea, and abdominal pain in people with celiac disease.

Choice C reason: Rice cereal is gluten-free and a good source of carbohydrates. Sliced bananas are gluten-free and a good source of potassium, fiber, and vitamin C.

Choice D reason: Rye toast contains gluten, which can harm people with celiac disease. Herbal tea is gluten-free and can help with hydration, but it does not provide enough calories or nutrients.

Choice A reason: Limiting high-calorie supplements to between meals is not a good strategy for managing anorexia while receiving radiation therapy because it can reduce the appetite and intake of regular meals, which are more nutritious and balanced. High-calorie supplements should be used as an addition to, not a replacement for, regular meals.

Choice B reason: Avoiding overeating during 'good' days is not a good strategy for managing anorexia while receiving radiation therapy because it can cause discomfort, nausea, or vomiting, which can worsen anorexia and affect the tolerance of radiation therapy. Eating should be based on hunger and satiety cues, not on good or bad days.

Choice C reason: Consuming nutrition-dense foods first is a good strategy for managing anorexia while receiving radiation therapy because it can ensure adequate intake of calories, protein, vitamins, and minerals, which are essential for healing and recovery. Nutrition-dense foods are those that provide high amounts of nutrients per serving, such as eggs, cheese, nuts, beans, and meat.

Choice D reason: Eating hot foods rather than cold foods is not a good strategy for managing anorexia while receiving radiation therapy because it can irritate the mouth and throat, which may be inflamed or sore due to radiation therapy. Cold foods are more soothing and refreshing for the mouth and throat, such as ice cream, yogurt, smoothies, and popsicles.
