Calculation
A nurse is preparing to administer lidocaine 50 mg IV bolus. Available is lidocaine 200 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
The ordered dose is 50 mg, and the available concentration is 200 mg/mL. To calculate the volume to administer: 50 mg ÷ 200 mg/mL = 0.25 mL. The nurse should administer 0.25 mL to provide the correct dose.
