by suzana123 Oct 10, '12Hi all,I'm having problem with this question:A procainamide drip is ordered (2gms in 250ml D5W) to infuse at 4 mg/min. The patient weighs 165lb. Calculate the drip rate in ml/hr for which theinfusion pump will be set at. Many thanks

Oct 10, '12 by bayouStep 1. Convert g to mg
2g =2000 mg
Step 2. How many hours will be used
2000 mg / 4 mg =500 mins = 500/60 =50/6 hrs
Step 3. 250 ml / 50/6hrs = 30 ml/hr
Patient weight no need in this case.
It can be solved in different way. - Oct 10, '12 by suzana123Thank you so much!! If it's not too much to ask what is the other way to solve this?Thanksl
- Oct 10, '12 by lavender59Here's another way to arrive at 30mL /hr using dimensional analysis.
Cross out units that are the same.
4mg/min x 1g/1000mg x 250mL/g x 60min/1hr = 60,000/2,000 =30mL/hrLast edit by lavender59 on Oct 10, '12 : Reason: typos - Oct 11, '12 by suzana123Thank you all so much,
