HESI: Dosage Calculations Assignment Quiz (Answered) 100% Correct
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. {{Answer:- 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.) {{Answer:- 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.
