The healthcare provider prescribes a continuous intravenous infusion of dextrose 5% and 0.45% sodium chloride with KCl 20 mEq/1000 ml to be delivered over 8 hours. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numericvalue only. If rounding is required, round to the nearest whole number.) 125 Using the formula volume/time: 1000 ml/8 hours = 125 ml/hour 2. A client receives a prescription for an intravenous infusion 0.45% sodium chloride 500 ml tobe 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 3. A client returns to the nursing unit from surgery with a prescription for Lactated Ringer'ssolution 1,000 ml to be infused over 10 hours. The IV administration set delivers 60gtts/ml. The nurse should regulate the infusion to deliver how many gtts/minute? 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 administeredat 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.) 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 4. The healthcare provider prescribes an IV solution of 5% dextrose in water with magnesiumsulfate 4 gram/50 ml to be infused over 30 minutes for a client with preeclampsia. Thenurse should program the infusion pump to deliver how many ml/hour? (Enter numericvalue only. If rounding is required, round to the nearest whole number.) 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
