What might a nurse monitor in a patient receiving both an ACE inhibitor and a diuretic?

Monitoring electrolyte imbalances in a patient receiving both an ACE inhibitor and a diuretic is crucial because these medications can significantly affect electrolyte levels in the body. Diuretics, commonly referred to as "water pills," increase urine production, which can lead to the loss of electrolytes such as potassium, sodium, and magnesium. Meanwhile, ACE inhibitors, while primarily used to manage blood pressure and heart failure, can also influence kidney function and electrolyte balance, potentially leading to hyperkalemia (elevated potassium levels). The combination of these two classes of medications heightens the risk of imbalances, necessitating close observation to prevent complications such as arrhythmias or muscle weakness.

While monitoring blood sugar levels, fluid retention, and heart rate are important aspects of patient care, they are not as directly impacted by the combination of an ACE inhibitor and a diuretic. Therefore, monitoring for electrolyte imbalances is particularly critical in this scenario to ensure patient safety and proper therapeutic management.
