What potassium level should prompt a nurse to contact the physician before administering furosemide?

• A. 4.5 mEq/L
• B. 3.0 mEq/L
• C. 5.0 mEq/L
• D. 6.0 mEq/L

Answer: (B)

In the context of administering furosemide, it is critical to monitor potassium levels as this diuretic can lead to significant potassium loss, which may result in hypokalemia (low potassium levels). A potassium level of 3.0 mEq/L indicates hypokalemia and would warrant immediate attention. Furosemide is particularly contraindicated when potassium levels are low because the risk of cardiac complications increases significantly. Hypokalemia can lead to serious health issues, including cardiac arrhythmias, especially in patients who may already have underlying conditions affecting heart function. The potassium level of 3.0 mEq/L is well below the normal range and should prompt the nurse to contact the physician before administration of furosemide to ensure that corrective action can be taken. This may involve administering potassium supplements or considering alternative treatments to avoid further diminishing potassium levels and causing harm to the patient.
