Which of the following should a nurse monitor for a patient receiving furosemide?

Furosemide is a loop diuretic commonly used to manage conditions such as heart failure, hypertension, and edema. One of the key actions of furosemide is its ability to promote diuresis, leading to increased urine production. This increased urine output can result in significant changes in electrolyte balance, as the drug promotes the excretion of not only water but also important electrolytes such as sodium, potassium, magnesium, and calcium.

Monitoring electrolyte levels is crucial while a patient is on furosemide because imbalances can lead to serious complications. For instance, hypokalemia (low potassium) can cause cardiac arrhythmias, while hyponatremia (low sodium) can lead to neurological issues. Therefore, assessing electrolyte levels helps ensure patient safety and the effective management of any potential side effects associated with diuretic therapy.

In contrast to electrolyte monitoring, tracking blood glucose levels, cholesterol levels, or hematocrit levels are not primary concerns when administering furosemide. While alterations in blood glucose may be relevant in broader patient management, they are not directly impacted by furosemide therapy. Cholesterol levels are not an immediate concern related to furosemide’s mechanism of action. Hematocrit levels
