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.)

1. Identify the desired dose: The physician has ordered lidocaine 200 mg per dose. 2. Identify the concentration of the available medication: The available lidocaine injection is 300 mg in 3 mL. This means the concentration is 300 mg / 3 mL. 3. Calculate the volume needed to deliver the desired dose using the formula: Desired Dose (mg) / Available Concentration (mg/mL) = Volume to Administer (mL) 4. Calculate the available concentration in mg/mL: Available Concentration = 300 mg / 3 mL = 100 mg/mL 5. Plug the values into the formula: Volume to Administer = 200 mg / 100 mg/mL 6. Solve for the volume to administer: Volume to Administer = 2 mL 7. Round the answer to the nearest whole number: The calculated volume is already a whole number (2). 8. Apply leading zero if it applies: A leading zero is not needed as the answer is a whole number greater than or equal to 1. 9. Ensure no trailing zero is used: The answer is 2, with no trailing zero. Answer: The nurse should administer 2 mL per dose.
