A nurse in a clinic is caring for a client who has gastroenteritis. The nurse compares the client's condition from two days ago and today. Which of the following changes should the nurse report to the provider?

Choice B reason: Older adults should decrease their calorie intake as their metabolic rate and physical activity tend to decline with age. Excess calories can lead to weight gain and increase the risk of chronic diseases such as diabetes, cardiovascular disease, and some cancers. Older adults should aim for a balanced diet that meets their nutritional needs without exceeding their energy requirements.

Choice A reason: Older adults should not decrease their vitamin D intake, as vitamin D is essential for bone health and immune function. Older adults are at risk of vitamin D deficiency due to reduced sun exposure, decreased skin synthesis, and impaired absorption. Vitamin D deficiency can cause osteoporosis, fractures, muscle weakness, and infections. Older adults should consume adequate amounts of vitamin D from fortified foods, supplements, or sun exposure.

Choice C reason: Older adults should not decrease their protein intake, as protein is important for maintaining muscle mass, strength, and function. Older adults are prone to sarcopenia, which is the loss of muscle mass and quality due to aging. Sarcopenia can impair mobility, balance, and independence. Older adults should consume enough protein from animal or plant sources to prevent or delay sarcopenia.

Choice D reason: Older adults should not decrease their fiber intake, as fiber is beneficial for digestive health and blood glucose control. Older adults often suffer from constipation, diverticular disease, and diabetes, which can be alleviated by increasing fiber intake. Fiber can also lower cholesterol levels and reduce the risk of heart disease and some cancers. Older adults should consume at least 25 grams of fiber per day from fruits, vegetables, whole grains, legumes, nuts, and seeds.

Choice A reason: Consuming high-calorie foods early in the day is not a good strategy for weight loss, as it can lead to overeating and increased fat storage. The nurse should advise the client to eat a balanced breakfast that includes protein, fiber, and healthy fats, which can help curb appetite and boost metabolism.

Choice B reason: Limiting carbohydrate intake to 30 grams per day is too restrictive and may cause nutritional deficiencies, ketosis, and adverse effects on mood and cognition. The nurse should recommend a moderate carbohydrate intake of 45 to 65 percent of total calories, with an emphasis on complex carbohydrates from whole grains, fruits, vegetables, and legumes.

Choice C reason: Consuming 500 fewer calories per day can result in a weight loss of about 1 pound per week, which is a safe and realistic goal for a client who has a BMI of 35. The nurse should help the client identify sources of excess calories in their diet and suggest ways to reduce them, such as choosing low-calorie beverages, using smaller plates, and avoiding distractions while eating.

Choice D reason: Following a liquid meal plan for 4 weeks is not a sustainable or healthy way to lose weight, as it can cause muscle loss, electrolyte imbalance, and rebound weight gain. The nurse should encourage the client to eat regular meals that include a variety of foods from all food groups, with appropriate portion sizes and nutrient density.
