A nurse is preparing to administer heparin 250 units/kg subcutaneously to a client who weighs 150 lb. The heparin is available in a prefilled syringe containing 10,000 units/mL. How many mL should the nurse administer?

Choice A rationale

Vitamin C is crucial for collagen synthesis, which is necessary for tissue repair and wound healing. It also enhances the immune response and promotes iron absorption, supporting the overall healing process.

Choice B rationale

Thiamine, a B-vitamin, facilitates carbohydrate metabolism and neural function. While essential, it does not have a direct role in wound healing or tissue regeneration.

Choice C rationale

Niacin supports energy production and DNA repair but lacks a specific role in promoting collagen synthesis or wound healing, making it less critical for this purpose.

Choice D rationale

Vitamin D maintains calcium-phosphorus homeostasis and bone health. While important for skeletal support, it does not directly enhance wound healing mechanisms.

Choice A rationale

A high-calorie diet is crucial for clients with AIDS and malnutrition to meet the increased metabolic demands caused by the disease and to compensate for nutrient deficiencies. Proper nutrition supports immune function and aids in maintaining muscle mass and energy levels, which are often compromised in malnourished clients.

Choice B rationale

Encouraging three large meals daily may not be appropriate, as clients with AIDS and malnutrition often experience gastrointestinal discomfort, nausea, or early satiety. Smaller, more frequent meals are typically better tolerated and can improve overall nutritional intake compared to larger meals.

Choice C rationale

Administering an antiemetic after each meal may help reduce nausea and improve food intake in some cases. However, this action should be based on the client's specific needs and symptoms. It is not a universal intervention for malnutrition in clients with AIDS and does not directly address the need for adequate calorie intake.

Choice D rationale

Including seasonings and spices may enhance the flavor of meals and encourage food intake. However, strong spices can sometimes exacerbate gastrointestinal symptoms in clients with AIDS. This action is not as effective or essential as providing a high-calorie diet to address malnutrition.
