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: 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.

Choice A reason: Reducing the client's sodium intake is an appropriate intervention for the nurse to take because it can help prevent fluid retention and edema, which are complications of heart failure. Sodium intake should be limited to 2 g per day or less for clients who have heart failure.

Choice B reason: Restricting the client's protein intake is not an appropriate intervention for the nurse to take because it can cause malnutrition and muscle wasting, which can worsen heart failure. Protein intake should be adequate to meet the client's nutritional needs and support cardiac function. Protein intake should be about 0.8 to 1.2 g per kg of body weight per day for clients who have heart failure.

Choice C reason: Weighing the client once per week is not an appropriate intervention for the nurse to take because it can delay the detection and treatment of fluid overload, which can worsen heart failure. The client should be weighed daily at the same time and with the same scale and clothing to monitor fluid status and adjust medication dosage.

Choice D reason: Providing the client with three large meals per day is not an appropriate intervention for the nurse to take because it can increase the workload of the heart and cause dyspnea, fatigue, or chest pain, which are symptoms of heart failure. The client should be provided with small, frequent meals that are low in sodium, fat, and cholesterol to reduce cardiac stress and promote digestion.
