What should a nurse assess before administering a diuretic?

Before administering a diuretic, it is essential for the nurse to assess the patient’s electrolyte levels and kidney function. Diuretics promote increased urine production, which can lead to fluid and electrolyte imbalances. Assessing electrolyte levels is crucial because diuretics can significantly affect levels of sodium, potassium, and other electrolytes. For example, some diuretics can cause hypokalemia (low potassium levels), which can lead to serious cardiac complications.

Additionally, evaluating kidney function is vital as these medications are primarily excreted through the kidneys. Impaired renal function can affect how the body processes the diuretic, potentially leading to ineffective treatment or increased side effects. Therefore, ensuring that electrolyte levels and kidney function are stable before administration allows for safer and more effective use of diuretics, reducing the risk of complications associated with their use.
