Expert Solution

Option A - 51 is correct.

Physician's order: heparin sodium IV bolus of 80 units/kg.

Maintenance drip rate set at 14 units/kg/hour

Patient's weight: 200lb

Dose available: 25,000 units of heparin in 1000mL D5W

Weight in kg = 91kg

Total dose of heparin to be administered = 14 x 91/hour

= 1,274 units/hour.

Here 1000ml = 25,000units.

'X' ml = 1274 units. Apply cross multiplication principles.

=25,000X = 1274 x 1000

X = (1274 x 1000) / 25,000 = 50.96

= 51(round off value)

So infusion rate of heparin should be set at 51ml/hr.
