Management of Care QID 940

The nurse is reviewing the laboratory results of a client with a central venous catheter. Which result warrants immediate intervention by the nurse?

A:
Hemoglobin level of 13.5 g/dL.
B:
Potassium level of 4.2 mEq/L.
C:
Sodium level of 140 mEq/L.
D:
White blood cell count of 18,000/mm3.

Explanation

A white blood cell count of 18,000/mm3 is indicative of an infection and is a significant finding in a client with a central venous catheter, which is a potential source of bloodstream infection. The nurse should immediately assess the client for signs of infection and notify the healthcare provider. The other laboratory results are within normal limits and do not require immediate intervention.
