A nurse is caring for a client who requires total parenteral nutrition (TPN). Which of the following actions should the nurse take when finding that the TPN solution is infusing too rapidly?

Choice A reason: Sitting the client upright may help with respiratory symptoms if fluid overload or dyspnea occurs, but it does not address the underlying issue of rapid TPN infusion. It is a supportive measure, not a corrective action. Choice B reason: Stopping the TPN infusion is the immediate and appropriate response to prevent complications such as hyperglycemia, fluid overload, and electrolyte imbalance. TPN must be administered at a controlled rate to avoid metabolic disturbances. Halting the infusion allows the nurse to reassess and notify the provider for further instructions. Choice C reason: Adding insulin to the TPN solution is a preemptive measure used when hyperglycemia is anticipated or present. It is not a corrective action for rapid infusion and should only be done under provider orders with proper monitoring. Choice D reason: Turning the client on the left side is a maneuver used in certain emergency situations, such as air embolism, but it is not relevant to TPN infusion rate issues. It does not mitigate the risks associated with rapid nutrient delivery.
