The fluconazole is dissolved in 100 mL of NS and is to be infused over 45 minutes. Using an IV controller, how many milliliters per hour should the fluconazole be infused? __ 100 ml/ .75 hr = 133.3 Linezolid 600 mg IV once a day is ordered for a patient.

Using tubing with a drop factor of 10 gtt/mL, how many drops per minute should the linezolid be infused? __ (300x 10 )/ 60min = 50 A patient on a ventilator has an order for a continuous midazolam drip at 4 mg/h. The midazolam concentration is 50 mg/50 mL of NS. Using an IV controller, how many milliliters per hour should the midazolam be infused? __ 50 mg/ 50 ml = 1 mg/ml 4 mg/ hr = 4 ml/4mg The patient has levofloxacin 500 mg ordered once daily. The levofloxacin is available in 100 mL of NS and should infuse over 60 minutes. Using an IV pump, how many milliliters per hour should the levofloxacin be infused? __ 100 ml of NS infused over 60 mins 100 The patient has vancomycin 750 mg ordered once daily. The vancomycin is available in 250 mL of NS and should infuse over 1 hour. Using tubing with a 10 gtt/mL drop factor, how many drops per minute should the vancomycin be infused? __ (250 x 10 ) / 60 = 41.7 = 42 ROUND TO WHOLE NUMBER FOR DROPS Linezolid 600 mg IV once a day is ordered for a patient. The linezolid is dissolved in 300 mL of NS and should infuse over 90 minutes. Using an IV controller, how many milliliters per hour should the linezolid be infused? __ 60mins/90mins = .6666667 300 x .6666667 = 200 An end-of-life patient has an order for fentanyl IV at 50 mcg/h. The fentanyl concentration is 10 mcg/mL. Using an IV controller, how many milliliters per hour should the fentanyl be infused? __ 10 mcg / ml 50 mcg/ 10 mcg = 5 5 ml/ hr Order: Begin a heparin drip per the facility’s protocol. The patient’s weight is 154 lb. Heparin Protocol Bolus: Heparin 80 units/kg. Bolus vial contains 1,000 units per mL. Infusion: Heparin 18 units/kg/h using a concentration of heparin 25,000 units in 250 mL of NS (100 units/mL). Calculate the number of mL/hr required to deliver continuous infusion. 154 lb / 2.2 kg= 70 18 x 70 kg = 1,260 units per hr 250 ml/25,000 = x ml/ 1,260 315,000 = 25,000x x= 12.6 Order: Begin a heparin drip per the facility’s protocol. The patient’s weight is 96 kg. Heparin Protocol Bolus: Heparin 80 units/kg. Bolus vial contains 1,000 units per mL. Infusion: Heparin 18 units/kg/h using a concentration of heparin 25,000 units in 250 mL of normal saline. Calculate the milliliters per hour of heparin required for the continuous infusion ____ 18 x 96 kg = 1728 units per hr 250 ml/25,000 = x ml/ 1728 x= 17.3 Begin a heparin drip per the facility’s protocol. The patient’s weight is 96 kg. Heparin Protocol Bolus: Heparin 80 units/kg. Bolus vial contains 1,000 units per mL. Infusion: Heparin 18 units/kg/h using a concentration of heparin 25,000 units in 250 mL of NS (100 units/mL). What is the number of units that will be given for the initial bolus dose? ___ 96 x 80 7,680 Order: Begin a heparin drip per the facility’s protocol. The patient’s weight is 154 lb. . . . . . . . .
