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.) ---------CORRECT ANSWER-----------------110
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 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.) ---------CORRECT ANSWER-----------------1.9
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.
,The nurse is preparing to administer Hepatitis B Vaccine, Recombinant (Energix-B)
5 mcg IM 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). ---------CORRECT ANSWER-----------------0.5
Use ratio and proportion, 5 mcg : X ml :: 10 mcg : 1ml 10X = 5 X = 0.5 ml
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

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.) ---------CORRECT ANSWER-----------------1
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 with multiple sclerosis is prescribed Dantrolene (Dantrium) 0.1 grams PO
bid for spasticity. Dantrolene is available in 100 mg capsules. How many capsules
,should the nurse administer? (Enter numeric value only.) ---------CORRECT

Using the conversion of 1 gram = 1000 mg: 0.1 gram = 100 mg 100 mg = 1
capsule
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.) ---------CORRECT ANSWER-----------------1.2
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
The healthcare provider prescribes acetazolamide (Diamox) 600 mg/m2/day
divided into 3 doses. The nurse calculates the child's body surface area (BSA) as
0.7 m2. How many mg should the child receive per dose? (Enter the numeric
value only.) ---------CORRECT ANSWER-----------------140
Using the child's BSA, 0.7 m2, calculate the mg/dose, 600 mg x 0.7 m2 = 420
mg/day/3 doses = 140 mg/dose
, 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.) ---------CORRECT 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 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,
