A client with hypertension who weighs 72.4 kg is receiving an infusion of nitroprusside (Nipride)
50 mg in D5W 250 ml at 75 ml/hour. How many mcg/kg/minute is the client receiving? (Enter
numeric value only. If rounding is required, round to the nearest tenth.) - CORRECT

ANSWER-3.5

,Calculate the mg/hour infusing,

50 mg : 250 ml = X : 75 ml



=250X = 3750 and X = 15 mg/hour.




Next, convert mg/hr to mcg/hour



15 mg/hour = 1 mg / 1000 mcg = 15,000 mcg/hour




then divide by 60 min

= 250 mcg/minute.

Lastly, 250 mcg/72.4 kg/min

= 3.45




= 3.5 mcg/kg/minute.




A client who weighs 70 kg is receiving a dopamine solution of 800 mg/500 ml normal saline at 5
ml/hour. How many mcg/kg/minute is the client receiving? (Enter numeric value only. If
rounding is required, round to the nearest tenth.) - CORRECT ANSWER-1.9




To change ml/hour to mcg/kg/minute, use the formula: desired rate (5 ml/hour) / volume
available (500 ml) x dose available (800 mg)

, = 8 mg/hour.



Next, convert milligrams/hour to mcg/kg/minute:

mg (8) x 1000 / kg (70) / 60 minutes

= 1.904



= 1.9 mcg/kg/minute.

infusing? (Enter numeric value only. If rounding is required, round to the nearest tenth.) -

CORRECT ANSWER-1.1



Convert grams to mg, 1 gram equals 1,000 mg.



Using ratio and proportion

1,000 mg : 250 ml :: X mg : 1ml

1000mg/250 mL = X mg/ 1 ml



=250X= 1,000
