A nurse is preparing to administer lidocaine 200 mg IM stat and repeat in 60 min. Available is lidocaine injection 300 mg/3 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Here's the calculation to determine the volume to administer per dose: 1. Lidocaine concentration per milliliter (mL): Concentration (mg/mL) = Total lidocaine (mg) / Volume (mL) Concentration (mg/mL) = 300 mg / 3 mL Concentration (mg/mL) = 100 mg/mL 2. Volume to administer for 200 mg dose: Dosage (mg) / Concentration (mg/mL) = Volume (mL) 200 mg / 100 mg/mL = 2 mL Therefore, the nurse should administer 2 mL of lidocaine injection per dose.
