I'm having trouble solving this problem. Looks easy, but maybe I'm trying to put too much info to solve. Okay here it goes:

The dose of a drug for a patient is 0.8 mg/kg/hr for 12 hours. How many ml of an IV solution containing 800 mg per 100 ml would be required for a 242 lb. male over this 12 hour period.
A. 96mL
B. 132mL
C. 264mL
D. None of the above

B. 132mL

242lbs/2.2lbs/kg=110kg

0.8mg/kg/hr*12hrs=9.6mg/kg/12hrs

110kg*9.6mg/kg/12hrs=1056mg/12hrs

1056mg
------*100mL=132mL
800mg

Hmm?

What?! Where did 96mg come from?

This is the formula

0.8/kg/hr X 110kg X 100ml
800mg

That calculation gives you 11 which you multiply by 12hrs which gives you 132.
