you're asked to start a CRI of 3mg/kg/hr to last 24 hours for an 82 pound patient receiving IV fluids at a rate of 100 ml/hr. The drug concentration is 50 mg/mL. How many milliliters must you add to each liter of fluids? show calculations
CRI to start is 3mg/kg/hr
The iv fluid rate is 100ml/hr
Drug concentration is 50mg/ml
Now convert pounds to kg each pound is 2.2kg
So 82/2.2= 37.2 so 37kg
Now take the kg and multiply by dose
37×3 mg= 111mg/hr
Now divide the no of hours in a day to get per hour rate
111mg/day/ 24hrs/day = 4. 62 so round it to 5mg/hour
Next divide the concentration
5mg/hour/50 mg/ml = 0.1/hour
Now divide how many hours this bag will last based by taking the amount of fluid in the bag divided by current fluid rate
1000ml/100ml=10hours of iv fluids/bg
Lastly take the number of hours this bag will last and multiply by the ml/hour
10hours× 0.1ml = 1ml
Therefore 1ml /1000ml to be added.
