Using the Desired/Have x Volume formula: Desired = 0.25 mg Have = 1 mg
Volume = 4 ml 0.25 mg/1 mg x 4 ml = 1 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.)

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

A client who has a gastrostomy feeding tube is receiving 3/4 strength Ensure 240 ml
every 6 hours. Full strength Ensure is available in a 240 ml can. The nurse should use
how many ml of Ensure to prepare the feeding? (Enter numeric value only. If needed,
round to the nearest whole number.)

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.)

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 who had mitral valve replacement surgery receives a prescription for
dextrose 5% in water with 0.5 grams of dobutamine in 250 ml for IV infusion at a rate
of 5 mcg/kg/minute. The client weighs 75 kg. The nurse should program the infusion
pump to deliver how many ml/hr? (Enter numeric value only. If rounding is required,
round to the nearest tenth.)

First calculate the number of mcg/kg/minute: 5 x 75 = 375 mcg/minute.
Calculate the number of mcg/hour: 375 x 60 minutes = 22,500 mcg/hour.
Next calculate the number of ml/hour needed to administer 22,500
mcg/hour: 500,000 mcg : 250 ml :: 22,500 mcg/ X ml 500,000X = 5,625,000
X = 11.25 (rounded to 11.3 ml/hour).
