A nurse is planning care for a client who has a new prescription for total parenteral nutrition (TPN). Which of the following actions should the nurse plan to take?
Remove TPN from the refrigerator 5 min before infusing it.
Change the dressing around the IV site weekly.
Change the IV tubing for TPN solution every 72 hr.
Discard remaining TPN solution that is still infusing after 24 hr.
The Correct Answer is D
Choice A Rationale: TPN should be removed from the refrigerator 30 minutes to an hour before use to allow it to reach room temperature, reducing the risk of crystallization and patient discomfort.
Choice B Rationale: The dressing around the IV site for TPN should be changed every 48 to 72 hours, not weekly, to prevent infection and ensure the integrity of the IV site.
Choice C Rationale: IV tubing for TPN solutions should be changed more frequently than every 72 hours, typically every 24 hours, to minimize the risk of bacterial contamination and infection.
Choice D Rationale: TPN solutions are at risk for bacterial growth, so any remaining solution after 24 hours should be discarded to prevent infection.
