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. 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 400x = 4500 X = 11.25 = 11.3 Ml. So, 18
Mg/11.3 Ml Should Be Infused At 11.3 Ml/Hour.




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.)
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.)
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>> Convert Grams To Mg, 1 Gram Equals 1,000 Mg. Using Ratio And Proportion - 1,000
Mg : 250 Ml :: X Mg : 1ml 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.




The Nurse Is Preparing The Change-Of-Shift Report For A Client Who Has A 265 Ml Secondary
