Answer #1

Ordered dose 250ml D5W with 400 mg Dopamine, run @10mcg/kg/min

Client weight is 140 pounds (63.5 kg)

So, the patient need 635mcg/min

63.5kg x 10mcg/kg/min = 635mcg/min

Quantity available 250ml D5W with 400 mg Dopamine

so, 250ml = 400mg = 0.625ml/mg

means 0.625ml contains 1mg(1000mcg)

So, 0.000625 ml contains 1 mcg of drug. 0.625ml = 1000mcg = 0.000625ml

patient needs 635mcg/min, Means Patient required 0.396 ml per minute.

0.396ml/min\times 60min=23.76ml/hr

So, Patient requires 23.76 ml per hour

0.000625ml x 635mcg = 0.39ml

Standard micro drip tubing is 60gtt/ml

Drop calculation formula is (Volumein ML + Timein Min) x Dropfactor

(23.76ml = 60min) x 60gtt/ml = 23.76gtt/min (24 drops per min)

Answer - patient requires 24 drops per minutes
