A patient is receiving a secondary infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. The intravenous (IV) administration set delivers 10 gtt/mL. How many gtt/min should the nurse regulate the infusion?
Correct answer
42
Rationale
Infusion rate: 500 mL / 2 hr = 250 mL/hr. Drops per minute: (250 mL/hr × 10 gtt/mL) / 60 min = 41.67, rounded to 42 gtt/min. This ensures accurate delivery of azithromycin.
