A child who is scheduled for a kidney transplant receives a prescription for basiliximab
(Simulect) 20 mg IV 2 hours prior to surgery. The medication is available in a 20 mg vial
that is reconstituted by adding 5 ml sterile water for injection, and administered in a 50
ml bag of normal saline over 30 minutes. The nurse should program the infusion pump
to deliver how many ml/hour? (Enter the numeric value only.) - ANS110
After reconstituting the medication vial, the nurse adds the 5 ml of medication to the 50
ml of sterile water to result in a 55 ml volume to infuse in 30 minutes. Using the formula,
Volume/Time = 55 ml / 0.5 hours = 110 ml/hour
A client experiencing cardiogenic shock receives a prescription for an IV infusion of
0.9% normal saline with milrinone (Primacor) 10 mg in 100 ml at a rate of 46
mcg/minute. The nurse should program the infusion pump to deliver how many ml/hour?
(Enter numeric value only. If rounding is required, round to the nearest whole number.) -
ANS28
First calculate the number of mcg/hour: 46 mcg x 60 minutes = 2760 mcg/hour Next
calculate the number of ml/hour needed to administer 2760 mcg/hour: 10,000 mcg : 100
ml :: 2760 mcg : X 10, :: 100 / X 10,000X = 276000 X = 27.6 (rounded to) 28
ml/hour
A client has a prescription for inamrinone (Inocor) 0.75 mg/kg IV bolus to be delivered
over 3 minutes. The client weighs 80 kg. Inamrinone is available for injection 100 mg/20
ml. How many ml of inamrinone should the nurse administer? (Enter numeric value
only. If rounding is required, round to the nearest tenth.) - ANS12
First calculate the mg/kg dosage needed: 0.75 mg x 80 kg = 60 mg needed Then
calculate Desired / Have x ml 60 mg / 100 mg x 20 ml = 12 ml
A client receives a prescription for an intravenous infusion 0.45% sodium chloride 500
ml to be infused over 6 hours. The nurse should program the infusion pump to deliver
how many ml/hour? (Enter numeric value only. If rounding is required, round to the
nearest whole number.) - ANS83
Calculate using Volume/Time: 500 ml/6 hours = 83.3 ml/hour
A client who has a sinus infection is receiving a prescription for amoxicillin/clavulanate
potassium (Augmentin) 500 mg PO q8 hours. The available form is 250 mg
, amoxicillin/125mg clavulanate tablets. How many tablets should the nurse administer
for each dose? (Enter numeric value only.) - ANS2
Using Desired/Available formula: 500 mg/250 mg x 1 tablet = 2
A client who has AIDS is receiving octreotide (Sandostatin) 1,200 mcg by subcutaneous
injection every day for symptoms of diarrhea. Octreotide is available for injection in 1
mg/ml vials. How many ml should the nurse administer? (Enter the numeric value only.
If rounding is required, round to the nearest tenth.) - ANS1.2
First, to convert micrograms to milligrams, divide the number of micrograms by 1000:
1,200/1000 = 1.2 mg. Using the Desired/Have available formula: 1.2 mg/1 mg x 1 ml =
1.2 ml
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 the numeric
value only. If rounding is required, round to the nearest tenth.) - ANS1.9
To change ml/hour to mcg/kg/minute, use the formula: desired rate (5 ml/hour) / volume
available (500ml) x dose available (800mg) = 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 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.) - ANS11.3
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 receives a prescription for carteolol (Cartel) 7.5mg PO daily.
The drug is available in 2.5 mg tablets. How many tablets should the nurse administer?
(Enter numeric value only.) - ANS3
Using D/H: 7.5mg / 2.5mg = 3 tablets
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.) - ANS3.5
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
