What action is inappropriate for the nurse to take regarding a client on TPN who reports poor feeding tolerance?

The choice to increase the TPN (Total Parenteral Nutrition) rate without a physician's order is inappropriate because any modifications to the TPN regimen must be made under the guidance of a healthcare provider. An increase in the TPN rate can lead to significant complications, including hyperglycemia, electrolyte imbalances, and fluid overload, particularly when a patient is already experiencing poor feeding tolerance.

The proper approach requires a thorough assessment and collaboration with the healthcare team to adjust the TPN rate safely, ensuring that any changes are appropriate for the client’s condition and nutritional needs. Nurses play an essential role in monitoring and reporting the patient's status, but alterations to TPN must be physician-ordered to ensure patient safety and to adhere to established protocols.
