Order: ceftriaxone 2 g in 100 mL of 0.9% NaCI (normal saline solution) over 30 minutes Available: Macro drip set: 15 gtt/mL Calculate the IV flow rate in gtt/min.

1. Determine the total volume to be infused: 100 mL 2. Calculate the infusion time in minutes: 30 minutes 3. Calculate the drip rate (gtt/min): Drip rate = (Total volume / Infusion time) x Drop factor Drip rate = (100 mL / 30 minutes) x 15 gtt/mL Drip rate = 50 gtt/min Therefore, the correct answer is 50 gtt/min
