Question:
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.
,Question:
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
,Question:
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
Question:
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
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
, Question:
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, :: 100 / X 10,000X
= 276000 X = 27.6 (rounded to) 28 ml/hour.
Question:
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
