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 numeric value only. -
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
The nurse notes that a client is receiving an oxytocin (Pitocin) infusion via a pump that is programmed to
deliver 30 ml/hour. The available solution is Ringer's Lactated 1,000 ml with Pitocin 20 units. How many
milliunits/minute is the client receiving? (Enter numeric value only.) - ANSWER-10
,2|Page
Convert units to milliunits,
20 x 1,000 = 20,000 units.
Using D/H x Q =
30 ml/hour X/20,000 units x 1,000 ml
= 30 ml/hour (60 minutes) X/20 =30/60, reduce X/2 = 1/2, and 2X = 20, so X = 10 milliunits/minute OR
20/1,000 = 0.02 1000 : 0.02 :: 30 : X = 0.6 :: 1,000X X = 600 and 600/60 = 10 milliunits/minute.
A client is receiving Heparin Sodium 25,000 Units in 5% Dextrose Injection 500 ml IV at 1,000 unit/hour
per protocol for acute coronary syndrome (ACS). The client's partial thromboplastin time (PTT) is 76
seconds. Based on the ACS protocol, the infusion should be decreased by 100 units/hour for a PTT
between 71 to 80 seconds. The nurse should program the pump to deliver how many ml/hour? (Enter
numeric value only.) - ANSWER-18
Adjust the infusion to 900 units/hour (1,000 units/hour minus 100 units/hour per protocol). Using the
formula, D/H x Q, 900 units/1 hour divided by 25,000 units x 500 ml = 90/5= 18 ml/hour.
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.) - 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.
A child who weighs 55 pounds receives a prescription for atovaquone with proguanil (Malarone
Pediatric) 125 mg/50 mg PO daily. A drug reference states that children 11 to 20 kg should receive 1
pediatric tablet daily; 21 to 30 kg should receive 2 pediatric tablets daily; 31 to 40 kg should receive 3
pediatric tablets daily; and greater than 40 kg should receive 1 adult tablet daily with food. The drug is
available as atovaquone 62.5 mg/proguanil 25 mg pediatric tablets. How many tablets should the nurse
administer? - ANSWER-2
, 3|Page
Calculate each drug component dose, using the formula, D/H 125 mg / 62.5 mg (atovaquone) = 2
combined with 50 mg / 25 mg (proguanil) = 2. The child should receive 2 tablets.
A client receives a prescription for azithromycin (Zithromax) 500 mg PO x 3 days. Azithromycin is
available as 250 mg scored tablets. How many tablets should the nurse administer per dose? (Enter
numeric value only. - ANSWER-2
Using the formula, DO/DA
500 mg/250 mg
= 2 tablets
The healthcare provider prescribes oxytocin (Pitocin) 0.5 milliunits/minute for a client in labor. One liter
Ringer's Lactate with 10 units of oxytocin (Pitocin) is infusing. The nurse should program the infusion
pump at how many ml/hour? (Enter numeric value only.) - ANSWER-3
Using the formula, D/H x Q, 0.5 milliunits / 10,000 milliunits x 1000 ml = 0.05 ml/minute. Multiply by 60
minutes = 3 ml/hour.
Docusate sodium (Colace) 0.3 grams is prescribed for a client who has frequent constipation. Each
capsule contains 100 mg. How many capsules should the nurse administer? - ANSWER-3
Using the known equivalent, 1 gram = 1000 mg, the nurse should first convert the dose to the same unit
of measurement, which is
=0.3 gram = 300 milligram.
Using the formula, DO / DA x 1 capsule
= 300/100 x 1
= 3 capsules.
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.
