false Item 51164 By Sheila Duncan Heparin Protocol:
Heparin loading dose: 60 units/kg IV, rounded to the nearest 100 units, followedby
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'sdose
using the formula D/H x Q = 4,000 units / 5,000 units x 1 ml = 4/5 = 0.8 ml
