A nurse is caring for a client who follows a vegan diet. The nurse should identify that the client is at risk for which of the following deficiencies?

Choice A reason: Changing the feeding to a continuous infusion may not improve the constipation, as it does not address the fluid deficit or the fiber content of the formula. Continuous infusion may also increase the risk of aspiration, diarrhea, and bacterial contamination¹.

Choice B reason: Increasing the amount of free water can help prevent or treat constipation by hydrating the stool and facilitating its passage. The client's fluid intake and output indicate a fluid deficit, which can contribute to constipation. The recommended fluid intake for adults is 30 to 35 mL/kg/day².

Choice C reason: Decreasing the infusion rate of feeding may worsen the constipation, as it reduces the caloric and fluid intake of the client. The infusion rate should be based on the client's nutritional needs and tolerance¹.

Choice D reason: Requesting a prescription for a diuretic is not appropriate, as it would further dehydrate the client and aggravate the constipation. Diuretics are indicated for clients with fluid overload, not fluid deficit³.

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.
