Question

The nurse is caring for a client receiving total parenteral nutrition (TPN). The TPN has been infusing 24 hours. Which of the following findings requires intervention?

Blood sugar is 115 mg/dl

White blood cell count is 11,500

Albumin level is 3.7 g/dl

Potassium level is 3.6 mmol/l

Answer 1

The finding that requires intervention in a TPN patient is the potassium level at 3.6 mmol/L, as it is on the lower range of normal and TPN can cause electrolyte imbalances. Other values listed are within normal ranges.

Step-by-step explanation:

The nurse is caring for a client receiving total parenteral nutrition (TPN). Among the listed findings, the one that requires intervention is the potassium level at 3.6 mmol/L. While this is within the lower range of normal serum potassium levels, TPN can contribute to electrolyte imbalances, particularly in the context of high glucose solutions that can drive potassium into cells and lower serum potassium levels, which may necessitate an adjustment in the infusion. Monitoring of electrolytes is critical in patients on TPN to prevent complications such as arrhythmias related to hypokalemia. The other values, including a blood sugar of 115 mg/dl, a white blood cell count of 11,500, and an albumin level of 3.7 g/dl, are within normal ranges and do not present immediate concern.
