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.) - __100% correct answer as 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.) - __100% correct answer as 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.) - __100% correct answer as 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 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.) - __100% correct answer as
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.
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.) -
__100% correct answer as 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.) -
__100% correct answer as 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.
