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.) - ANSWER-180
240 ml Ensure : 1 :: X ml Ensure : 0.75 240/X : .75 X = 240 x 0.75 = 180 ml Ensure + 60 ml water =
240 ml
0.9% normal saline with inamrinone (Inocor) 0.1 grams/100 ml is prescribed for a client with heart

infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round
to the nearest whole number.) - ANSWER-24
,2|Page
First calculate the number of mcg/hour: 400 mcg x 60 minutes = 24000 mcg/hour. Next calculate the
number of ml/hour needed to administer 24,000 mcg/hour: 100,000 mcg: 100ml :: 24,000 mcg : X
100,000/24,000 :: 100/X 100,000X = 2,400,000 X = 24 ml/hour.
A client experiencing cardiogenic shock receives a prescription for an IV infusion of 0.9% normal saline
with milrinone (Primacor) 10 mg in 100 ml at a rate of 46 mcg/minute. The nurse should program the
infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round
to the nearest whole number.) - ANSWER-28
First calculate the number of mcg/hour: 46 mcg x 60 minutes = 2760 mcg/hour. Next calculate the
number of ml/hour needed to administer 2760 mcg/hour: 10,000 mcg : 100 ml :: 2760 mcg : X 10,000 /
2760 :: 100 / X 10,000X = 276000 X = 27.6 (rounded to) 28 ml/hour.
A client with septic shock receives a prescription for dextrose 5% in water with dopamine (Intropin) 0.6
grams/250 ml at a rate of 5 mcg/kg/minute. The client's weight is 148 lbs. 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 whole number.) - ANSWER-8
First convert the weight into kilograms: 148 pounds/2.2 kg = 67 kg. Next calculate the number of
mcg/kg/minute: 5 x 67 x 1 minute = 335 mcg/min. Calculate the number of mcg/hour: 335 x 60 minutes
= 20,100 mcg/hour. Now calculate the number of ml/hour needed to administer 20,100 mcg/hour:
600,000 mcg : 250 ml :: 20,100 mcg : X ml 600,000/20100 :: 250/X 600,000X = 5,02500 X = 8.375
(rounded to) 8 ml/hour.
A client with type 2 diabetes is receiving metformin (Glucophage) 1 gram PO twice daily. The medication
is available in 500 mg tablets. How many tablets should the nurse administer? (Enter numeric value
only.) - ANSWER-2
A client returns to the nursing unit from surgery with a prescription for Lactated Ringer's solution 1,000
ml to be infused over 10 hours. The IV administration set delivers 60 gtts/ml. The nurse should regulate
the infusion to deliver how many gtts/minute? - ANSWER-100
First convert hours to minutes: 10 hrs x 60 = 600 minutes. Using the formula Volume/Time x drop factor:
1000 ml /600 minutes = 1.66666 x 60 = 100 gtts minute.

An IV infusion of dextrose 5% in normal saline with oxytocin (Pitocin) 20 units in 1,000 ml is prescribed
for a client to control postpartum bleeding. The solution is to be administered at a rate of 2 mu/minute.
The nurse should program the infusion pump to administer how many ml/hour? (Enter numeric value
only. If rounding is required, round to the nearest whole number.) - ANSWER-6
First calculate the number of units/hour. 0.002 units/minute x 60 minutes = 0.12 units/hour. Next
calculate the number of ml/hour needed to administer 0.12 units/hour. 20 units : 1,000 ml :: 0.12 units :
X 20/0.12 :: 1,000/X 20X : 120 X = 6
The healthcare provider prescribes an IV solution of 5% dextrose in water with magnesium sulfate 4
gram/50 ml to be infused over 30 minutes for a client with preeclampsia. The nurse should program the
infusion pump to deliver how many ml/hour? (Enter numeric value only. If rounding is required, round
to the nearest whole number.) - ANSWER-100
To calculate the rate of infusion for ml/hour: 50 ml: 30 minutes :: X ml : 60 minutes 50 ml / X ml :: 30
min / 60 min 3000 = 30X X = 100 ml/hour
Using the known equivalent, 1 gram = 1000 mg, the nurse should first convert the dose to the same unit
of measurement, which is 1 gram = 1000 mg. Using the formula, Desired / Available x 1 tablets: 1000 mg
/ 500 mg x 1 = 2 tablets
A client with Mycobacterium avium complex (MAC) is receiving an infusion of 5 % dextrose in water with
amikacin (Amikin) 0.572 grams/100 ml every 12 hours. The nurse prepares the dose of amikacin using a
vial labeled, 250 mg/ml. How many ml should the nurse add to the infusion? (Enter numeric value only.
If rounding is required, round to the nearest tenth.) - ANSWER-2.3
First convert gram to milligram: 1 gm = 1000mg .572 gram x 1000 = 572 mg. Next use the formula D/H x
Q: 572/250 x 1 = 2.288 (rounded to) 2.3 ml.
A client with pericardial effusion has phrenic nerve compression resulting in recurrent hiccups. The
healthcare provider prescribes metoclopramide (Reglan) liquid 10 mg PO q 6 hours. Reglan is available
as 5 mg/5 ml. A measuring device marked in teaspoons is being used. How many teaspoons should the
nurse administer? - ANSWER-2
, 4|Page
First, using the formula, Desired dose/dose on Hand x Quantity of volume on hand (D/H x Q), 10 mg / 5
mg x 5ml = 10 ml. Next using the known conversion of 5 ml = 1 tsp: 5 ml : 1 tsp :: 10 ml : X : 1 / X
5X = 10 X = 2
A client is receiving alprazolam (Xanax) 0.75 mg PO BID for anxiety. Alprazolam is available in 0.5 mg
scored tablets. How many tablets should the nurse administer? (Enter numeric value only.) - ANSWER-
1.5
Using the conversion of 1 gram = 1000 mg: 0.1 gram = 100 mg 100 mg = 1 capsule
A client with multiple sclerosis is prescribed Dantrolene (Dantrium) 0.1 grams PO BID for spasticity.
Dantrolene is available in 100 mg capsules. How many capsules should the nurse administer? (Enter
numeric value only.) - ANSWER-1
Using the conversion of 1 gram = 1000 mg: 0.1 gram = 100 mg 100 mg = 1 capsule
A client has a prescription for inamrinone (Inocor) 0.75 mg/kg IV bolus to be delivered over 3 minutes.
The client weighs 80 kg. Inamrinone is available for injection 100 mg/20 ml. How many ml of inamrinone
should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest
tenth.) - ANSWER-12
First calculate the mg/kg dosage needed: 0.75 mg x 80 kg = 60 mg needed. Then calculate Desired /
Have x ml 60 mg / 100 mg x 20 ml = 12 ml.
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.) - ANSWER-11.3
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).
