The physician orders a Lidocaine drip to infuse at 2 mg/min. The drug is available as 2 gm in 500 ml of fluid. Solve for ml/hr.
The Correct Answer is ["3"]
Lidocaine infusion calculation:
- Lidocaine dose ordered: 2 mg/min
- Lidocaine concentration: 2 gm in 500 mL
- Conversion factor: 1 mg = 1000 mcg
Calculations:
- Convert Lidocaine dose to mcg/min: 2 mg/min × 1000 mcg/mg = 2000 mcg/min
- Lidocaine concentration is 2 gm in 500 mL, which equals 4000 mcg/mL.
- Calculate mL/hr:
- mL/hr = (2000 mcg/min × 60 min/hr) / 4000 mcg/mL = 3 mL/hr
Answer:
- mL/hr: 3 mL/hr
