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? (If rounding is required, enter a whole
number.)
100 gtts/minute
First convert hours to minutes:10 hrs x 60 = 600 minutesUsing the formula Volume/Time x drop
factor:1000 ml /600 minutes = 1.66666 x 60 = 100 gtts/minute
A client with hypertension receives a prescription for carteolol (Cartel) 7.5mg PO daily. The drug is
available in 2.5 mg tablets. How many tablets should the nurse administer? (Enter numeric value only,
whole number.)
3 tablets.
Using D/H: 7.5mg / 2.5mg = 3 tablets
A client with septic shock receives a prescription for dDextrose 5% in Water (D5W) 250 ml with
dopamine (Intropin) 0.6 grams/250 ml at a rate of 5 mcg/kg/minute. The client's weight is 148 pounds
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.)
,8 ml/hr
First convert the weight into kilograms: 148 pounds/2.2 kg = 67 kgNext calculate the number of
mcg/kg/minute: 5 x 67 x 1 minute = 335 mcg/minuteCalculate the number of mcg/hour: 335 x 60
minutes = 20,100 mcg/hourNow calculate the number of ml/hour needed to administer 20,100
mcg/hour: 600,000 mcg : 250 ml :: 20,100 mcg : X ml600, :: 250 / X = 600,000X = 5,02500X =
8.375 (rounded to) 8 ml/hour
A client who weighs 70 kg is receiving a solution of 0.9% Sodium Chloride (Normal Saline) 500 ml with
dopamine 800 mg at 5 ml/hour. How many mcg/kg/minute is the client receiving? (Enter the numeric
value only. If rounding is required, round to the nearest tenth.)
1.9 mcg/kg/minute
To change ml/hour to mcg/kg/minute, use the formula: desired rate (5 ml/hour) / volume available
(500ml) x dose available (800mg) = 8 mg/hour.Next, convert milligrams/hour to mcg/kg/minute: mg (8)
x 1000 / kg (70) / 60 minutes = 1.904 = 1.9 mcg/kg/minute.
A client with cardiogenic shock who weighs 220 pounds is receiving a solution of Dextrose 5% in
Water (D5W) 250 ml with dopamine 400 mg at the rate of 3 mcg/kg/minute. 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 tenth.)
11.3 ml/hour
First, convert pounds to kg, 220 lb : X = 2.2 lb : 1 kg = 100 kgNext, calculate the dosage per minute, 3
mcg/kg/min x 100 kg = 300 mcg/minuteConvert mcg/min to mcg/hour, 300 mcg/min x 60 min=18,000
mcg/hour and Convert mcg/hour to mg/hour, 18,000 mcg/hr = 18.0 mg/hourCalculate the rate, 400 mg :
250 ml = 18 mg : X ml400X = 4500 X = 1.25 = 11.3 ml. So, 18 mg/11.3 ml should be infused at 11.3
ml/hour.
A client receives a prescription for a dose of medication 300 mg IV every 6 hours. The preparation
arrives from the pharmacy diluted in a secondary infusion of 0.9% Sodium Chloride (NaCl) 50 ml. The
nurse plans to administer the dose over 20 minutes. How many ml/hour should the nurse program
the infusion pump to deliver the secondary infusion? (Enter the numeric value only, rounded to a
whole number.)
150 ml/hour
The infusion rate is calculated as a ratio proportion problem.50 ml : 20 minutes :: X ml : 60 minutes20X =
30003000/20 = 150 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, whole number.)
,10 milliunits/minutes
Convert units to milliunits, 20 units x 1,000 = 20,000 milliunits.Using D/H x Q = 30 ml/hour:X/20,000
milliunits x 1,000 ml = 30 ml/hour (60 minutes).X/20 = 30ml/60 minutes, reduce to: X/2 = 1/2, and 2X =
20, so X = 10 milliunits/minute
A client receives a prescription for an intravenous infusion of Dextrose 5% in 0.45% Sodium chloride
(D51/2 NS) 500 ml to be infused over 6 hours. 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.)
83 ml/hr
Calculate using Volume/Time: 500 ml/6 hours = 83.3 ml/hour = 83 ml/hour
An IV seondary infusion of 0.9% normal saline 100 ml with inamrinone (Inocor) 0.1 grams/100 ml is
prescribed for client with heart failure. The medication is to be delivered at a rate of 400 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.)
24 ml/hr
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

burns to 60 percent of his body. Using the Parkland formula of 4 ml/kg/24 hours, the client should
receive how many ml of fluid during the first 24 hours? (Enter the numeric value only. If rounding is
required, round to the nearest whole number.)
19632 ml over the first 24 hours
Using the Parkland formula, the client's fluid requirements for the first 24 hours after injury:4 ml
lactated Ringer's solution x Body weight (in kilograms) x Percent burnConvert 180 pounds to kg = 180 /
2.2 = 81.8 kg4 ml x 81.8 kg x 60 = 19632 ml over the first 24 hours

A. 42 gtt/min.
B. 83 gtt/min.
C. 125 gtt/min.
D. 250 gtt/min.
B. 83 gtt/min.
Ratio proportion using Dimentional analysis.Drops/ Minutes (gtt/min) = 20gtt/ml X 1000 ml/4hrs X 1
hr/60 min = 83 gtts/minute
The healthcare provider prescribes a continuous infusion of 5% dextrose in 0.45% sodium chloride at

nearest whole number.)
14 gtt/minute
Volume/Time (minutes) x drop factor (gtt/ml) =85 ml/ 60 minutes x 10 gtt/ml = 14.16 = 14 gtt/minute
