of 0.9% normal saline with inamrinone (Inocor) 0.1 grams/100 ml at a rate of 8
,mcg/kg/minute. The client' s current weight is 183 lbs. The nurse should program

Next calculate the number of mcg/kg/minute: 8 x 83 = 664
mcg/min
Calculate the number of mcg/hour: 664 x 60 minutes = 39,840 mcg/hour
Now calculate the number of ml/hour needed to administer 39,840 mcg/hour:
100,000 mcg : 250 ml :: 39,840 mcg : X = 100,000/39,840 :: 250/X and 100,000X =
3,984,000
X = 39.84 (rounded to) 40 ml/hour
