When can a nurse change the rate of TPN infusion?

The correct response highlights the importance of adhering to protocols and maintaining patient safety when managing Total Parenteral Nutrition (TPN). Changing the rate of TPN infusion is a critical task that can significantly affect a patient's fluid balance, electrolyte levels, and overall health. Consequently, such changes should not be made arbitrarily or based solely on the patient's discomfort. Rather, any modification to the TPN infusion rate must be done under the guidance of a physician's order, which ensures that the change is medically appropriate and considers the patient's unique needs and clinical condition.

TPN is a specialized form of nutrition provided intravenously, and it typically comes with specific protocols, including prescribed rates of infusion that are calculated based on various factors, such as the patient's nutritional requirements and response to treatment. Adhering to a physician's order ensures that the nurse acts within legal and professional standards, maintaining patient safety and optimizing care.
