A nurse is caring for a client who is receiving continuous enteral nutrition and is experiencing diarrhea. Which of the following actions should the nurse take?

Choice A reason: Fever is not an indication of an allergic reaction, as it is a sign of infection or inflammation. The nurse should assess the infant for other causes of fever, such as ear infection, urinary tract infection, or viral illness.

Choice B reason: Jaundice is not an indication of an allergic reaction, as it is a sign of liver dysfunction or hemolysis. The nurse should evaluate the infant for other causes of jaundice, such as hepatitis, biliary atresia, or hemolytic anemia.

Choice C reason: Bruising is not an indication of an allergic reaction, as it is a sign of trauma or bleeding disorder. The nurse should examine the infant for other causes of bruising, such as injury, coagulopathy, or leukemia.

Choice D reason: Diarrhea is an indication of an allergic reaction, as it is a sign of gastrointestinal hypersensitivity or intolerance. The nurse should ask the parents about the infant's food intake, history of allergies, and symptoms of anaphylaxis, such as hives, swelling, or difficulty breathing.

Choice A reason: Warming the formula to room temperature can help reduce the osmotic load and prevent diarrhea in clients receiving enteral nutrition. Cold formula can also cause abdominal cramping and discomfort.

Choice B reason: Increasing the rate of infusion can worsen diarrhea by increasing the osmotic load and the risk of bacterial overgrowth. The rate of infusion should be adjusted based on the client's tolerance and nutritional needs.

Choice C reason: Changing to a low-calorie formula is not indicated for diarrhea. Low-calorie formulas are usually high in osmolality and can cause more water to be drawn into the intestinal lumen, leading to diarrhea. A low-residue or isotonic formula may be more appropriate.

Choice D reason: Replacing the extension tubing every 48 hr is not enough to prevent diarrhea. The extension tubing should be replaced every 24 hr or with each new container of formula to reduce the risk of bacterial contamination and infection.
