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
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?

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
Convert units to milliunits,
, 4|Page
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.
