What should a nurse do if a client is taking bumetanide and has a potassium level of 3.6 mEq/L?

Monitoring the potassium level closely is the most appropriate action for a client taking bumetanide, especially when the potassium level is at 3.6 mEq/L, which is within the lower end of the normal range (3.5 to 5.0 mEq/L). Bumetanide is a loop diuretic that can lead to potassium depletion, so it is important to keep an eye on the client's levels.

By choosing to monitor the potassium level, the nurse can ensure that the client's potassium remains stable and can intervene if it drops too low. Close monitoring allows for timely adjustments, whether that means administering supplements or changing the medication regimen if necessary. This is particularly critical as potassium plays a vital role in cardiac function and other physiological processes.

Adjusting the medication dosage or administering potassium supplements without reviewing the client’s lab results or their clinical status may overlook potential risks or necessary interventions. Stopping the medication suddenly could also pose risks if the client requires the diuretic for conditions such as heart failure or fluid overload. Therefore, maintaining vigilance through monitoring is the best course of action.
