NUR 119 Unit 3 Brain Exercise

Continuous heparin infusion is running at 13.4 ml\hr.  Heparin protocol states the infusion should be increased by 200 units/hr.  The heparin bag contains 10000 units in 500 ml 5% dextrose.

What would the new rate be in ml\hr?

Mathematical Equivalence

ON

Answer explanation

You need to add the newly calculated rate + the fluids are already running (continuous rate). So 10 + 13.4 = 23.4 mL/ hr.

Heparin supplied 25,000 units per 250ml (100 units/ml)

Bolus dose of 80 units/kg

Begin infusion of Heparin at 14 units/kg/hr

Patient’s weight is 52 kg

At what rate (mL/hr) would you begin the heparin infusion? Round answer to nearest tenth.

Answer explanation

7.28 must be rounded to the nearest tenth so 7.3 mL/hr

Patient's IV pump is running at 9 mL\hr.  The medication concentration is 100 units in 100 ml of 0.9% NS.

 

How many units per hour is the patient receiving? Round your answer to the whole number.
