A client admitted to the hospital has been placed on furosemide (Lasix) for the treatment of heart failure. Which side effect should the nurse monitor for associated with furosemide (Lasix)?

Choice A reason: Hypokalemia, or low potassium levels, is a common side effect associated with furosemide. Furosemide is a loop diuretic that works by inhibiting the reabsorption of sodium and chloride in the kidneys, which leads to an increase in urine output. This process can also cause the body to lose potassium, making hypokalemia a significant risk. Patients on furosemide are often monitored closely for signs of low potassium and may require potassium supplements to maintain appropriate levels. Choice B reason: Hypertension, or high blood pressure, is not a side effect typically associated with furosemide. In fact, furosemide is often used to help lower blood pressure by reducing fluid volume in the body. As a diuretic, it helps to decrease the amount of fluid that the heart must pump, thereby reducing blood pressure. Therefore, hypertension is not a relevant side effect to monitor for in this context. Choice C reason: Hypoglycemia, or low blood sugar, is not a side effect commonly linked to furosemide. Furosemide primarily affects electrolyte and fluid balance rather than glucose metabolism. While it is important for patients with diabetes to monitor their blood sugar levels, hypoglycemia is not directly associated with the use of furosemide, making this choice incorrect. Choice D reason: Hyperkalemia, or high potassium levels, is also not typically associated with the use of furosemide. Since furosemide increases the excretion of potassium through urine, it is more likely to cause hypokalemia rather than hyperkalemia. Monitoring for signs of high potassium would not be as relevant in patients taking furosemide, which is designed to help eliminate excess potassium from the body.
