Practice Test Assessment Performance You're learning! 89% Correct Incorrect 24 Correct 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.) Rationale 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 125 The healthcare provider prescribes a continuous intravenous infusion of Dextrose 5% in 0.45% sodium chloride ((D51/2 NS) with KCl 20 mEq / 1000 ml to be infused over 8 hours. How many ml/hour should the nurse program the infusion pump? (Enter numeric value only. If rounding is required, round to the nearest whole number.) Rationale Using the formula, volume/time: 1000 ml/8 hours = 125 ml/hour 100 The healthcare provider prescribes a secondary infusion of Dextrose 5% in Water (D5W) 50 mg IV with magnesium sulfate 4 gram/50 mI 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.) Rationale Using ratio and proportion to calculate the rate of infusion for ml/hour: 50 ml: 30 minutes :: X ml : 60 minutes 50 ml / X ml :: 30 min / 60 minutes 3000 = 30X X = 100 ml/hour 11.3 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.) Rationale 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/minute Convert 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/hour Calculate the rate, 400 mg : 250 ml = 18 mg : X ml 400X = 4500 X = 1.25 = 11.3 ml. So, 18 mg/11.3 ml should be infused at 11.3 ml/hour. What action should the nurse implement when accessing an implanted infusion port for a client who receives long term IV medications? Cleanse the site with iodine solution. Insert a Huber-point needle into the port. Flush tubing with 5 ml of normal saline. Place a sterile dressing over the port. Rationale An implanted infusion port needs to be accessed using a Huber-point needle (noncoring) to be prevent damage to the self-sealing septum of the port. The other actions are not necessary when accessing an implanted infusion port.
