, A client who weighs 70 kg is receiving a dopamine 1.9
solution of 800 mg/500 ml normal saline at 5 ml/hour.
How many mcg/kg/minute is the client receiving? To change ml/hour to mcg/kg/minute, use the formula: desired rate (5 ml/hour)
(Enter numeric value only. If rounding is required, round / volume available (500 ml) x dose available (800 mg) = 8 mg/hour. Next,
to the nearest tenth.) 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 Convert grams to mg, 1 gram equals 1,000 mg. Using ratio and proportion -
0.9% (Normal Saline) 250 ml with amiodarone 1,000 mg : 250 ml :: X mg : 1ml 250X= 1,000 so X = 4 mg/ml is the solution
(Cordarone) 1 gram at 17 ml/hour. How many mg/minute concentration of amiodarone. The infusion rate (ml/hour) x concentration
of amiodarone is infusing? (Enter numeric value only. If (mg/ml) divided by 60 minutes/hour 17 ml/hour x 4 mg/ml = 68/60 = 1.13 = 1.1
rounding is required, round to the nearest tenth.) mg/minute.
A client who weighs 176 pounds is receiving an IV 100
infusion with esmolol hydrochloride (Brevibloc) at 48
ml/hour. The IV solution is labeled with the Convert pounds to kg by dividing 176 pounds by 2.2 pounds = 80 kg. Convert
concentration of Brevibloc 10 mg/ml. How many the IV concentration from mg to mcg. 1 mg : 1000 mcg :: 10 mg : 10,000 mcg.
mcg/kg/minute is the client receiving? (Enter numeric Infusion rate (48 ml/hour) x concentration (10,000 mcg/ml) divided by 60
value only.) 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 95
client who has a 265 ml secondary infusion that was
started 2 hours ago at a rate of 85 ml/hour via an 85 ml x 2 hours = 170 ml has infused. 265 ml (total amount to be infused) - 170
infusion pump. The nurse should report that how many ml (amount infused) = 95 ml remain to be infused.
ml remain to be infused by the on-coming nurse? (Enter
numeric value only.)
A male client receives a prescription for ondansetron 2
hydrochloride (Zofran) 4 mg IV to prevent
postoperative nausea after an inguinal hernia repair. The Use ratio and proportion, 4 mg : X ml = 2 mg : 1 ml 2X = 4 X = 2
medication is available in 2 mg/ml. How many ml
should the nurse administer? (Enter numeric value only.)
The nurse is preparing to administer Hepatitis B 1 or 0.5
Vaccine, Recombinant (Energix-B) 5 mcg IM to a
school-aged child. The vaccine is labeled, 10 mcg/ml. Use ratio and proportion, 5 mcg : X ml :: 10 mcg : 1ml
How many ml should the nurse administer? (Enter 10X = 5 X = 0.5 ml
numeric value only. If rounding is required, round to the
nearest tenth).
