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 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.)
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 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.)
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 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.)

,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 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.)
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 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.)
95
85 ml x 2 hours = 170 ml has infused. 265 ml (total amount to be infused) - 170 ml (amount
infused) = 95 ml remain to be infused.
The nurse is preparing the change-of-shift report for a client who has a 265 ml secondary
infusion that was started 2 hours ago at a rate of 85 ml/hour via an infusion pump. The
nurse should report that how many ml remain to be infused by the on-coming nurse? (Enter
numeric value only.)

to a school-aged child. The vaccine is labeled, 10 mcg/ml. How many ml should the nurse
administer? (Enter numeric value only. If rounding is required, round to the nearest tenth).

30 mg (total dose) - 15 mg (dose already administered) = 15 mg that still needs to be
administered. Using the Desired/Have formula: 15 mg/15 mg = 1 tablet
A client's daily PO prescription for aripiprazole (Abilify) is increased from 15 mg to 30 mg.
The medication is available in 15 mg tablets, and the client already received one tablet
today. How many additional tablets should the nurse administer so the client receives the
total newly prescribed dose for the day? (Enter numeric value only.)
695
The tube feeding is administered at 75 ml/hour for 11 hours (0700 - 1800) and then turned
off for one hour because the residual is greater than 200 ml. 11 hours x 75 ml/hr = 825 ml.
Three doses of 20 ml of medication are administered, with 10 ml of water used to flush the
GT before and after each dose. 20 ml x 3 doses = 60 ml; 10 ml (flush) x 2 x 3 doses = 60 ml;
so 825 ml + 60 ml + 60 ml = 945 ml. 250 ml of residual is removed and not replaced. 945 ml
- 250 ml = 695 ml total fluid balance (Intake - output).
At the end of the shift, the nurse is recording the fluid balance for a client receiving a
continuous gastrostomy tube (GT) feeding. Based on the client's records, how many ml
should the nurse record for the total fluid balance (intake - output) for the shift that started
