A 62-year-old client on a postoperative unit is being evaluated for nursing care related to osmosis and tonicity. Assessment data include laboratory results return outside the expected range for this condition. Which nursing action should the nurse take first?

Hint: Apply ABCs, client stability, and NCSBN clinical judgment steps before choosing an intervention.
