Which fluid and electrolyte finding should be reported to the provider?

The choice of reporting potassium at 5.4 mEq/L is important due to the risks associated with higher potassium levels in the blood, a condition known as hyperkalemia. Potassium is a critical electrolyte for many body functions, especially for maintaining proper heart rhythm and muscle function. Normal potassium levels usually range from 3.5 to 5.0 mEq/L, so a level of 5.4 mEq/L is close to being elevated.

While this value may not be significantly high, it is above the upper normal limit and could pose risks for the patient, especially in individuals with renal impairment or those on medications affecting potassium levels. Sudden changes in potassium levels can lead to serious cardiac problems, which is why any value indicative of potential hyperkalemia warrants further evaluation and potential intervention by the healthcare provider.

In contrast, the other findings listed (BUN at 15 mg/dL, creatinine at 0.8 mg/dL, and sodium at 143 mEq/L) fall well within normal ranges and typically do not require immediate action or reporting. BUN and creatinine are markers used to assess kidney function, and the values given indicate normal kidney function. Sodium at 143 mEq/L is also
