Heparin protocol is prescribed for a client weighing 90 kg. Per protocol, the heparin loading dose is 60 units/kg IV rounded to the nearest 100 units, with a maximum loading dose of 4,000 units. The heparin vial is labeled 5,000 units/ml. How many ml should the nurse administer? (Enter the numeric value only. If rounding is required, round to the nearest tenth.) false Item 51164 By Sheila Duncan Heparin Protocol: Heparin loading dose: 60 units/kg IV, rounded to the nearest 100 units, followed by a maintenance infusion of 12 units/kg/hr, rounded to the nearest 100 units/hr. The maximum bolus is 4,000 units and the maximum initial infusion is 1000 units/hr. Determine the client loading dose: 60 units x 90 kg = 5,400 unit. Per protocol, use the maximum loading dose of 4,000 units, and calculate the client's dose using the formula D/H x Q = 4,000 units / 5,000 units x 1 ml = 4/5 = 0.8 ml or Use ratio and proportion: 5,000 : 1 ml :: 4,000 : X X = 0.8 ml A child weighing 28.4 kg is in hypertensive crisis. The healthcare provider prescibes methyldopa (Aldomet) 40 mg/kg/day IV in 4 divided doses. The pharmacy provides a 50 mg/ml injection vial. How many ml should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.) First calculate the total mg dose/day: 40 mg x 28.4 kg = 1136 mg/day Next divide the total mg into the 4 dosages for the day: 1136 mg/4 doses = 284 mg/dose Using the Desired/Have formula: 284 mg/50mg x 1 ml = 5.68 ml/ dose, rounded to 5.7 ml. A client with multiple sclerosis and muscle spasms receives a prescription for baclofen (Kemstro) 30 mg PO daily. The medication is supplied from the pharmacy in 20 mg scored tablets. How many tablets should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.) Use ratio and proportion, 30 mg : X tablets = 20 mg : 1 tablet 20X = 30 X = 1.5 A client with dehydration receives a prescription for an IV of Lactated Ringer's 1,000 ml to be administered over 8 hours. The nurse should program the infusion pump to deliver how many ml/hour? (Enter numeric value only, using whole number.)
