HESI Dosage Calculations Practice Exam With Complete Solutions Using the conversion of 1 gram = 1000 mg: 0.1 gram = 100 mg 100 mg = 1 capsule A client has a prescription for inamrinone (Inocor) 0.75 mg/kg IV bolus to be delivered over 3 minutes. The client weighs 80 kg. Inamrinone is available for injection 100 mg/20 ml. How many ml of inamrinone should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.) - 12 First calculate the mg/kg dosage needed: 0.75 mg x 80 kg = 60 mg needed. Then calculate Desired / Have x ml 60 mg / 100 mg x 20 ml = 12 ml. 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. The client weighs 75 kg. The nurse should program the infusion pump to deliver how many ml/hr? (Enter numeric value only. If rounding is required, round to the nearest tenth.) - 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 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 scheduled for surgery is to receive an IV infusion of 0.9% sodium chloride with prochlorperazine edisylate (Compazine) 10 mg/50 ml over 30 minutes. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only.) - 100 Calculate: 50 ml : 30 minutes :: X ml : 60 minutes 50/X :: 30/60 3000 = 15X X = 100 ml

HESI Dosage Calculations Practice Exam, Hesi Pharmacology Review 300 QUESTIONS AND ANSWERS GRADED A LATEST 2023/2024 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.) - CORRECT ANSWER 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 client with hypertension who weighs 72.4 kg is receiving an infusion of nitroprusside (Nipride) 50 mg in D5W 250 ml at 75 ml/hour. How many mcg/kg/minute is the client receiving? (Enter numeric value only. If rounding is required, round to the nearest tenth.) - CORRECT ANSWER 3.5 Calculate the mg/hour infusing, 50 mg : 250 ml = X : 75 ml 250X = 3750 and X = 15 mg/hour. Next, convert mg/hr to mcg/hour, 15 mg/hour = 1 mg / 1000 mcg = 15,000 mcg/hour, then divide by 60 min = 250 mcg/minute. Lastly, 250 mcg/72.4 kg
