Ordered: 8 mcg/kg/hr
Available: 0.64 mg/2 mL
Patient weighs 80 kg
What drip rate (mL/hr)? - ANSWER-8x80 = 640 mcg
0.64 = 640 mcg
(640/640)2 = 2 mL

Ordered: 24 mg over 8 hours
Available: 96 mg/4 mL
What drip rate (mL/hr)? - ANSWER-(24/96)4 = (0.25)4 = 1 mL
1 mL / 8 hrs = 0.125 mL/hr

Ordered: 400 mcg

(400/80)0.5 = 2.5 mL

Ordered: 117 mg/kg over 12 hours
Available: 260 mg/3 mL
Patient weighs 220 lbs
What drip rate (mL/hr)? - ANSWER-220 lbs/2.2 = 100 kg
117 x 100 = 11700 mg
(11700/260)3 = 45 mL over 12 hrs
45/12 = 3.75 mL/hr

Ordered: 6 mL over 12 hours
Available: 120 mg/4 mL
How many mg will the patient receive after 6 hours? - ANSWER-(6 mL/4 mL)120 mg =
180 mg over 12 hrs
Since 6 hrs is half of 12 hrs, the patient will receive half of the total mg. Thus, 180/2 =
90 mg
