10 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.

100 Convert pounds to kg by dividing 176 pounds by 2.2 pounds = 80 kg. Convert the IV concentration from mg to mcg. 1 mg : 1000 mcg :: 10 mg : 10,000 mcg. Infusion rate (48 ml/hour) x concentration (10,000 mcg/ml) divided by 60 minutes/hour x 80 kg = 48 x 10,000 divided by 60 x 80 = 480,000 / 4800 = 100 mcg/kg/minute.

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
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.

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).
A client with cardiogenic shock weighs 220 lb and is receiving dopamine at the rate of 3 mcg/kg/minute. The solution strength available is dopamine 400 mg in 250 ml of D5W. 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 First, convert pounds to kg, 220 lb : X = 2.2 lb : 1 kg = 100 kg. Next, calculate the dosage per minute, 3 mcg/kg/min x 100 kg = 300 mcg/min. Convert mcg/min to mcg/hour, 300 mcg/min x 60 min=18,000 mcg/hour. Convert mcg/hr to mg/hour, 18,000 mcg/hr = 18.0 mg/hour. Calculate the rate, 400 mg : 250 ml = 18 mg : X ml 400X = 4500 X = 11.25 = 11.3 ml. So, 18 mg/11.3 ml should be infused at 11.3 ml/hour.
A child who is scheduled for a kidney transplant receives a prescription for basiliximab (Simulect) 20 mg IV 2 hours prior to surgery.

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.)
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.

160 Determine the total volume needed at 80 ml/hour x 4 hours = 320 ml. Use the formula, Desired strength/strength on Hand x Volume = 50/100 x 320 = 160 ml of Osmolite® enteral formula, which must be diluted to half strength. Or use ratio and proportion, Desired strength (1/2 = 1 part : 2 parts) :: Volume of full strength : Total Desire volume 1 : 2 :: X : 320 ml 2X = 320, and X = 160 ml of Osmolite® enteral formula, full strength 320 ml total volume - 160 ml of full-strength formula = 160 ml of water to create 1/2 strength or 50% concentration.

If rounding is required, round to the nearest whole number.)
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
At the end of the shift, the nurse is recording the fluid balance for a client receiving a continuous gastrostomy tube (GT) feeding. Based on the client's records, how many ml should the nurse record for the total fluid balance (intake - output) for the shift that started at 0700 and ended at 1900? (Enter numeric value only.) (Click on each image asset for additional information.)
695 The tube feeding is administered at 75 ml/hour for 11 hours (0700 - 1800) and then turned off for one hour because the residual is greater than 200 ml. 11 hours x 75 ml/hr = 825 ml. Three doses of 20 ml of medication are administered, with 10 ml of water used to flush the GT before and after each dose. 20 ml x 3 doses = 60 ml; 10 ml (flush) x 2 x 3 doses = 60 ml; so 825 ml + 60 ml + 60 ml = 945 ml. 250 ml of residual is removed and not replaced. 945 ml - 250 ml = 695 ml total fluid balance (Intake - output).
A healthcare provider prescribes a continuous infusion of 0.9% sodium chloride with pancuronium (Pavulon) 25 mg/250 ml at a rate of 0.1 mg/kg/hr for a client with coronary artery bypass grafting. The client weighs 78 kg. 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 tenth.
78 First calculate the number of mg the client will receive in 1 hour: 0.1 mg x 78 kg = 7.8 mg/hour. Next calculate the number of ml containing 7.8 mg of medication: 25 mg : 250 ml :: 7.8 mg : X 25 mg/ 7.8 mg :: 250 ml/X 25X = 1950 X = 78 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.)
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 receives a prescription for an intravenous infusion 0.45% sodium chloride 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 Calculate using Volume/Time: 500 ml/6 hours = 83.3 ml/hour
The nurse is preparing the change-of-shift report for a client who has a 265 ml secondary infusion that was started 2 hours ago at a rate of 85 ml/hour via an infusion pump. The nurse should report that how many ml remain to be infused by the on-coming nurse? (Enter numeric value only.)
95 85 ml x 2 hours = 170 ml has infused. 265 ml (total amount to be infused) - 170 ml (amount infused) = 95 ml remain to be infused.

What is the maximum safe dose the nurse should administer? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
97 Determine the maximum number of mg this client should receive in a day: 48.5 kg x 8 mg/kg/day = 388 mg/day. Next determine how many mg the nurse should deliver each dose: 388 mg/4 doses = 97 mg.
A client is receiving an IV solution of sodium chloride 0.9% (Normal Saline) 250 ml with amiodarone (Cordarone) 1 gram at 17 ml/hour. How many mg/minute of amiodarone is infusing? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
Convert grams to mg, 1 gram equals 1,000 mg. Using ratio and proportion - 1,000 mg : 250 ml :: X mg : 1ml 250X= 1,000 so X = 4 mg/ml is the solution concentration of amiodarone. The infusion rate (ml/hour) x concentration (mg/ml) divided by 60 minutes/hour 17 ml/hour x 4 mg/ml = 68/60 = 1.13 = 1.1 mg/minute.
