Question 1 of 5
Which is the most important laboratory result for the nurse to present to the primary health care provider on a client who is receiving total parenteral nutrition (TPN)?
Correct Answer: B
Rationale: Serum electrolyte levels are critical to monitor in a client receiving TPN because TPN solutions contain high concentrations of glucose and electrolytes, which can lead to imbalances such as hyperkalemia, hypokalemia, or hyponatremia. These imbalances can cause serious complications, including cardiac dysrhythmias or neurological issues. While white blood cell count, arterial blood gas levels, and hemoglobin and hematocrit levels are important, they are not as directly related to the immediate risks associated with TPN administration as electrolyte levels.
