Which is true about administering furosemide?

• A. It should be given IV at a rapid rate to exert quick diuresis
• B. It can be given without potassium supplementation
• C. IV administration should be pushed slowly, not exceeding 20 mg/min
• D. It is safe to administer just before bedtime due to sleep disruption?

Answer: (C)

The main idea is that IV furosemide must be given slowly to balance fast diuresis with safety. Furosemide is a potent loop diuretic that blocks the Na-K-2Cl transporter, producing rapid fluid loss and also causing potassium and other electrolyte losses. If you push it too quickly, you risk abrupt shifts in fluid and electrolytes, which can lead to hypotension and additive risks like ototoxicity. That’s why the recommended approach is to administer IV furosemide no faster than about 20 mg per minute. For larger doses, it’s often given as a slower infusion to maintain diuresis while reducing adverse effects. Also keep in mind it can cause potassium wasting, so monitor electrolytes and consider supplementation as needed; and avoid bedtime dosing due to nocturia.
