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
Desired dose = 50 mg. Available concentration = 200 mg/mL. Calculate the volume to administer. Volume (mL) = Desired dose (mg) / Available concentration (mg/mL) = 50 mg / 200 mg/mL = 0.25 mL. Round the answer to the nearest tenth. = 0.3 mL.
