A nurse is providing teaching about formula feeding to the parents of an infant. Which of the following instructions should the nurse include?

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.

Choice A reason: TPN is a form of nutrition that is delivered directly into the bloodstream through a central venous catheter. It is used for clients who have impaired or nonfunctional gastrointestinal tracts, such as those with acute kidney injury, bowel obstruction, or short bowel syndrome.

Choice B reason: The TPN does not necessarily have higher levels of vitamins than the recommended daily intake. The TPN is individually tailored to meet the client's nutritional needs, which may vary depending on their condition, weight, and laboratory values.

Choice C reason: The TPN does not ensure that the client's glucose level stays within the expected range. In fact, TPN can cause hyperglycemia due to the high concentration of dextrose in the solution. The client's blood glucose level should be monitored frequently and insulin should be administered as prescribed to prevent complications.

Choice D reason: The TPN is not higher in fats and protein, but lower in carbohydrates. The TPN contains a balanced mixture of macronutrients, including carbohydrates, proteins, and lipids, as well as micronutrients, such as electrolytes, vitamins, and minerals. The ratio of these components may vary depending on the client's nutritional needs and goals.
