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.
50 gtt/min
15 gtt/min
10 gtt/min
100 gtt/min
The Correct Answer is A
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

Correct Answer is A
Explanation
Convert the dosage to mcg per hour:
15mcg/min×60min/hr=900mcg/hr15
Convert the available nitroglycerin concentration to mcg/mL:
25mg=25,000mcg
Theconcentrationis(25,000mcg/250mL)=100mcg
Calculate the flow rate in mL per hour using the dosage and concentration:
Flowrate(mL/hr)=(900mcg/hr100mcg/mL)=9mL/hr
