What should the nurse do when a client on diuretics has a potassium level of 2.7 mEq/L?

When a client on diuretics presents with a potassium level of 2.7 mEq/L, it indicates a significant and concerning hypokalemia, as normal potassium levels generally range from 3.5 to 5.0 mEq/L. This low level can lead to serious complications such as muscle weakness, arrhythmias, or even cardiac arrest, especially in patients already on diuretics that can exacerbate potassium loss.

Notifying the healthcare provider about the potassium level being below normal is critical because it requires immediate attention and intervention. The provider may need to adjust the diuretic regimen, prescribe potassium supplements, or implement other measures to safely manage the patient's electrolyte status.

This action aligns with the standards of nursing practice, where recognizing and responding to laboratory values is essential for patient safety and effective care management. Prompt communication with the healthcare provider is necessary to prevent adverse outcomes associated with hypokalemia.
