A male client receives a prescription for ondansetron
hydrochloride (Zofran) 4 mg IV to prevent postoperative
nausea after an inguinal hernia repair. The medication is
available in 2 mg/ml. How many ml should the nurse
administer? (Enter numeric value only.) - Answer-2
Use ratio and proportion, 4 mg : X ml = 2 mg : 1 ml 2X = 4
X=2
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). - Answer-
1 or 0.5
Use ratio and proportion, 5 mcg : X ml :: 10 mcg : 1ml
10X = 5 X = 0.5 ml

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.) -
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
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 at 0700 and
ended at 1900? (Enter numeric value only.) (Click on each
image asset for additional information.) - Answer-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).
The nurse is administering a 250 milliliter (ml) intravenous
solution to be infused over 2 hours. How many ml/hour
should the nurse program the infusion pump? (Enter
numeric value only.) - Answer-125
250 ml : 2 hours = X ml : 1 hour 250 = 2X X = 250 divided
by 2 = 125 ml/hr
The nurse is preparing to administer 0.25 mg of
bumetanide (Bumex) IV. The medication is available in a
vial labeled 1 mg/4 ml. How many ml of medication should
the nurse administer? (Enter numeric value only.) -
Answer-1
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
, 4|Page
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.) - Answer-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.) - 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.

mcg/hour, 15 mg/hour = 1 mg / 1000 mcg = 15,000

250 mcg/72.4 kg/min = 3.45 = 3.5 mcg/kg/minute.
