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.

Answer and Explanation

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
