medium · NCLEX-RN Reduction of Risk Potential

The nurse is caring for a client with severe burns during the first 24 hours of resuscitation. The client's serum potassium is 5.9 mEq/L and the hourly urine output has decreased from 50 mL/hr to 15 mL/hr.

How should the nurse interpret these findings?

  1. The client needs an immediate bolus of potassium-sparing diuretics.
  2. The potassium rise is an error because burn clients are typically hypokalemic.
  3. Acute kidney injury and cellular destruction are causing hyperkalemia and oliguria.
  4. The client is successfully compensating for the fluid shift of the 'ebb' phase.
