A nurse is caring for a client who is receiving chemotherapy treatments. The client states, "I feel so nauseated after my treatments." Which of the following instructions should the nurse provide the client? (Select all that apply)

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: Offering the client a selection of beverages at each meal is not a good action to include in the plan, as it may reduce the client's appetite and intake of solid foods. The nurse should limit the client's fluid intake before and during meals, and encourage the client to consume high-calorie and high-protein drinks, such as milkshakes or smoothies, after meals.

Choice B reason: Informing the client that a weight gain of 2.3 kg (5 lb) per week is expected is not a good action to include in the plan, as it may cause anxiety and resistance in the client. The nurse should set realistic and individualized weight goals for the client, and monitor the client's weight and vital signs regularly. The nurse should also avoid focusing on the client's weight, and instead emphasize the client's health and well-being.

Choice C reason: Arranging for someone to remain with the client for 30 min after meals is a good action to include in the plan, as it can prevent the client from purging or exercising excessively. The nurse should provide a supportive and nonjudgmental environment for the client, and supervise the client's eating and toileting behaviors. The nurse should also educate the client and the family about the complications and treatment of anorexia nervosa.

Choice D reason: Encouraging the client to participate in developing dietary goals is a good action to include in the plan, as it can increase the client's sense of control and motivation. The nurse should collaborate with the client, the dietitian, and the mental health team to create a personalized and flexible meal plan that meets the client's nutritional and psychological needs. The nurse should also praise the client for any progress or achievement, and reinforce the client's positive coping skills.
