4 IU/kg every 12 hours, patient weighs 175 lbs.
1. Find weight in kg. Divide 175 by 2.2
2. Mulitply that weight by the # of units per kg to get dosage.
3. Once you figure the dosage...you'll know how many vials you need.

First, calculate pounds to kg. 175/2.2= 79.5 or 80 kg.
4 U/kg.. multiply 4x80= 320 Units I plan to administer, which would take 2 vials. Someone correct me if I am wrong.

To make the Benadryl calculation easier, you're giving 50ml in 15 minutes so there are (4) 15 minutes in an hour so 4 times 50ml=200 ml per hour.:wink2:
Thank you bunches!!!!!
