Ordered: heparin infusion 1000 units per hour Available: heparin 20,000 units in 1000 mL 0.9 NaCl solution How many mL/hr will the nurse run the infusion? - Answer 1000ml/20000units x 1000units/hr= 50 remember when ever the unit answer reads like mcg/kg/min the last part of the equation will always be the persons weight. - Answer Ordered: heparin infusion 750 units per hour Available: heparin 25,000 units in 500 mL How many mL/hr will the nurse run the infusion? (Round answer to the nearest whole number.) - Answer 500ml/25000units x 750units/1hr = 15 A 400 mg in 250 mL solution is ordered for a 89.7 kg patient to titrate between 4 and 10 mcg/kg/min. What is the maximum infusion rate (ml/hr)? (Round answer to the nearest whole number.) - Answer 250ml/400mg x 1mg/1000mg x 10mcg/1hr x 60min/1hr x 89.7kg = 33.63 = 34 A child weighing 19.3 kg is to receive 7.5-9 mg/kg/dose. Each dose is to infuse over 50 minutes. The supply is labeled 10 mg/mL. What is the recommended "maximum" dose (mg)? (Round answer to the nearest whole number.) - Answer 9mg x 19.3kg = 173.7 = 174 A child weighing 25 kg is to receive 7.5-9 mg/kg/dose. Each dose is to infuse over 60 minutes. The supply is labeled 25 mg/mL. What is the recommended "minimum" dose (mg)? (Round answer to the nearest whole number.) - Answer 7.5mg x 25kg = 187.5 = 188 A child weighing 35 kg is to recieve Tegretol elixir 30 mg BID. How many mL will be administered per dose? pic of bottle- label reads 100mg/5ml - Answer 30mg divided by 100mg x 5ml = 1.5 A patient is receiving an infusion at 75 mL/hr. How many mg/min is the patient receiving if the solution strength is 1 g in 500 mL and the patient weighs 73 kg? ( Round answer to nearest tenth.) - Answer forget about the weight, it doesn't mater in this convert g to mg 1000mg/500ml x 75ml/1hr x 60min/1hr = 2.5 A solution of 500 mg in 1000 mL is infusing at 5 mL/hr. The order reads titrate infusion between 0.4 and 0.8 mcg/kg/min. Is the current infusion within ordered limits if the patient weighs 61.4 kg? - Answer mcg/kg/min 1000mcg/1mg x 500mg/1000mg x 5ml/1hr x 1/hr x 1/61.4kg = 0.678 A solution of 4 g in 250 mL is ordered to infuse at 60 mcg/kg/min for a patient weighing 82.7 kg. How many mL/hr will the nurse administer the infusion? ______ mL/hr (Round answer to the nearest whole number.) - Answer ml/hr 250ml/4000mg x 1mg/1000mcg x 60mcg/kg-min x 60min/1hr x 82.7kg= 18.6 = 19 A 10 mcg/kg/min dosage is ordered for an adult weighing 61 kg. The solution available is 500 mg in 250 mL. How many mL/hr will the nurse administer the infusion? _______ mL/hr (Round answer to the nearest whole number.) - Answer ml/hr 250ml/500mg x 1mg/1000mcg x 10mcg/1min x 60/1hr x 61 = 18.3 = 18 An Heparin IV bag of 25,000 units in 500 mL NS is infusing at 40 ml/hr. How many units/hr are infusing? - Answer units/hrs 25000units/500ml x 40ml/1hr =2000
