Study Notes
Dosage Calculations in Medical Practice
- Lasix prescribed at 20 mg IV for a 34 lbs child calculated to 15.5 mg (requires a safe dose of 1 mg/kg).
- For Diphenhydramine, to administer 25mg from a 50mg/1ml vial, 0.5ml is needed using the proportion x=25/50.
- Initial Lidocaine dose of 1.5mg/kg for a 176 lbs patient results in 6ml (120 mg needed from a vial of 100mg/5ml).
- Second dose of Lidocaine calculated at 0.75mg/kg leads to 3ml administration (60 mg from 100mg/5ml).
- Morphine sulfate dosage for a 75-year-old male patient requires 1.25ml (5mg IV from 4mg/ml vial).
- Diazepam for a seizing patient calls for 0.8ml (4mg from 5mg/ml stock).
Infusion Rates
- Amiodarone protocol mix requires a calculation of drip rate; for 150mg in 100cc over 10 minutes with a microdrip set, it equals 600 gtts/min.
- Using a macrodrip set for Amiodarone yields a drip rate of 100 gtts/min for the same infusion.
- Lidocaine drip for a 154 lbs patient dictates a rate of 30 gtts/min calculated based on mg/min dosing from a 500ml NS solution.
- Dopamine administration for a 187 lbs patient requires 31.875 gtts/min from an 800mg/500ml bag, emphasizing dose in mcg/kg/min.
Drip Sets
- Micro drip set utilizes a factor of 60 gtts (drops) per ml.
- Macro drip set has a conversion factor of 10 gtts per ml.
