Which of the following is the next appropriate nursing action? The nurse is caring for a client who has been in good health up to the present and is admitted with cellulitis of the hand. The client's serum potassium level was 4.5 mEq/L yesterday. Today the level is 7 mEq/L.
A client who has been in good health up to the present is admitted for cellulitis of the hands. When the serum potassium goes from 4.5 mEq/L to 7.0 mEq/L with no risk factors for hyperkalemia, false high results should be suspected because of hemolysis of the specimen. The physician would likely question results as well. Bananas are a food high in potassium. Seizures are not a clinical manifestation of hyperkalemia.
