A nurse is preparing to administer olanzapine 10 mg IM to a client who has schizophrenia. Available is olanzapine 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Desired dose: 10 mg Available concentration: 5 mg/mL To determine the volume to administer, we can use the following formula: Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL) Volume to administer = 10 mg / (5 mg/mL) = 2 mL Therefore, the nurse should administer 2 mL of olanzapine.
