A client with cardiogenic shock weighs 220 lb and is receiving dopamine at the rate of 3
mcg/kg/minute. The solution strength available is dopamine 400 mg in 250 ml of D5W. The
nurse should set the infusion pump to deliver how many ml/hour? (Enter numeric value only.
If rounding is required, round to the nearest tenth.) - ANSWER -11.3
First, convert pounds to kg
220 lb : X = 2.2 lb : 1 kg
= 100 kg.
Next, calculate the dosage per minute,
3 mcg/kg/min x 100 kg
= 300 mcg/min.
3(100kg) =300
Convert mcg/min to mcg/hour
300 mcg/min x 60 min
=18,000 mcg/hour.
Convert mcg/hr to mg/hour,
=18,000 mcg/hr
,= 18.0 mg/hour.
Calculate the rate,
400 mg : 250 ml = 18 mg : X ml
= 400 mg 18 mg
_____________ = ___________
250mL x mL
=400X = 4500
X = 11.25
= 11.3 ml.
So, 18 mg/11.3 ml should be infused at 11.3 ml/hour.
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.) - 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.
A client is receiving an IV solution of sodium chloride 0.9% (Normal Saline) 250 ml with
amiodarone (Cordarone) 1 gram at 17 ml/hour. How many mg/minute of amiodarone is
infusing? (Enter numeric value only. If rounding is required, round to the nearest tenth.) -
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
so X = 4 mg/ml is the solution concentration of amiodarone.
The infusion rate (ml/hour) x concentration (mg/ml) divided by 60 minutes/hour
17 ml/hour x 4 mg/ml = 68/60
= 1.13
=1.1 mg/minute.
A client who weighs 176 pounds is receiving an IV infusion with esmolol hydrochloride
(Brevibloc) at 48 ml/hour. The IV solution is labeled with the concentration of Brevibloc 10
mg/ml. How many mcg/kg/minute is the client receiving? (Enter numeric value only.) -
ANSWER -100
Convert pounds to kg by dividing 176 pounds by 2.2 pounds = 80 kg.
Convert the IV concentration from mg to mcg.
1 mg : 1000 mcg :: 10 mg : 10,000 mcg.
Infusion rate (48 ml/hour) x concentration (10,000 mcg/ml) divided by 60 minutes/hour x 80
kg = 48 x 10,000 divided by 60 x 80 = 480, = 100 mcg/kg/minute.
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.) -

=18,000 mcg/hour.
Convert mcg/hr to mg/hour,
=18,000 mcg/hr

so X = 4 mg/ml is the solution concentration of amiodarone.
The infusion rate (ml/hour) x concentration (mg/ml) divided by 60 minutes/hour
17 ml/hour x 4 mg/ml = 68/60
= 1.13
=1.1 mg/minute.
