A nurse is preparing to administer olanzapine 210 mg IM to a client who has schizophrenia Available is olanzapine 300 mg/2 mL How many mL the nurse administer? (Round to the nearest tenth. Use a leading zero if it applies: Do not use a trailing zero)

Determine the concentration of the olanzapine injection: Available concentration: 300 mg / 2 mL Calculate the volume (in mL) needed for a 210 mg dose: Use the concentration as a conversion factor: Volume (mL) = Ordered dose (mg) / Concentration (mg/mL) Volume (mL) = 210 mg / (300 mg / 2 mL) Simplify the complex fraction: Volume (mL) = 210 mg x (2 mL / 300 mg) Calculate: Volume (mL) = (210 x 2) / 300 = 420 / 300 = 1.4 mL
