A nurse is caring for a client who is receiving total parenteral nutrition. Which of the following laboratory results indicates a possible complication of this therapy?

A nurse caring for a client who is receiving total parenteral nutrition should identify that a serum calcium level of 12.5 mg/dL indicates a possible complication of this therapy. Total parenteral nutrition can result in electrolyte imbalances, including hypercalcemia (high levels of calcium in the blood). The other laboratory results are within normal ranges and do not indicate a complication of total parenteral nutrition. b) A BUN level of 16 mg/dL is within the normal range. c) A serum potassium level of 4.6 mEq/L is within the normal range. d) A WBC count of 8,000/mm³ is within the normal range.
