A nurse is providing discharge teaching to a client who will be receiving total parenteral nutrition (TPN) at home. Which of the following instructions should the nurse include? (Select all that apply.)

Rationale: A. The client should not infuse dextrose solution independently if TPN runs out; this could cause serious metabolic complications. B. TPN should not be stopped abruptly once weight gain is achieved; discontinuation should be gradual to prevent hypoglycemia. C. Maintaining the prescribed infusion rate is important to ensure proper nutrient delivery and prevent metabolic complications. D. TPN should never be shaken if a precipitate is present; this can cause embolism or catheter occlusion. E. TPN should be refrigerated when not in use to prevent bacterial contamination and preserve solution stability.
