Question

A patient weighs 145 lb and is receiving a medication via an IV (600 mg/500 mL) infusion at 20 mL/hr per volumetric pump. How many mcg/kg per minute is being given? (1 mcg = 1 μg).

Answer 1

In this case scenario, has to follow following formulas:

Pt weight - 145 Lb converts into kg as 66kg,

Iv Dose -600mg/500ml if we convert into micrograms, this 600mg equals to 6,00,000 mcg,

Infusion rate in volumetric infusion pump is 20ml/Hr, to achieve this find how many hrs it takes place by using following formula,

Total volume/Total time = 500ml/25hr which gives 20 ml/hr,

now, how much mg/per hr= 600/25=24 mg/hr now covert into 24 mg/min=0.4mg

Now convert 0.4mg into Micrograms is 400mcg,

   Hence, we have to be given 400 mcg/kg/ min.
