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.) - Correct 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.) - 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 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.) - Correct Answer-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.)
- Correct Answer-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.)
- Correct Answer-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 = 480,000 / 4800 = 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

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 male client receives a prescription for ondansetron hydrochloride (Zofran) 4 mg IV to

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-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.) -
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
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.) - Correct 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.) - Correct 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

ml 0.25 mg/1 mg x 4 ml = 1 ml
A client with hypertension receives a prescription for carteolol (Cartel) 7.5 mg PO daily.

A 180-pound adult male is admitted to the Emergency Center after receiving thermal
burns to 60 percent of his body. Using the Parkland formula of 4 ml/kg/24 hours, the
client should receive how many ml of fluid during the first 24 hours? (Enter numeric
value only. If rounding is required, round to the nearest whole number.) - Correct
Answer-19632
Using the Parkland formula, the client's fluid requirements for the first 24 hours after
injury: 4 ml lactated Ringer's solution x Body weight (in kilograms) x Percent burn.
Convert 180 pounds to kg = 180 / 2.2 = 81.8 kg 4 ml x 81.8 kg x 60 = 19632 ml over the
first 24 hours.
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 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 loading dose of acetylcysteine (Mucomyst) 8 grams, which is available as a 20%
solution (200 mg acetylcysteine per ml) is prescribed by nasogastric tube for a client
with acetaminophen toxicity. How many ml of diluent should be added to the medication
to obtain a 1:4 concentration? (Enter numeric value only. If rounding is required, round
to the nearest whole number.) - Correct Answer-120
8 grams = 8,000 mg prescribed dose. Using the formula, D/H x Q, 8,000 mg / 200 mg x
1 ml = 40 ml of the 20% solution. Dilute the 40 ml to a 1:4 concentration for
administration using ratio and proportion, 1 : 4 solution :: 40 ml : X X= 160 ml total
volume to administer. Subtract total volume of 160 ml - 40 ml of 20% concentration =
120 ml diluent is added to obtain a 1:4 concentration.
