A nurse is preparing to administer haloperidol decanoate 75 mg IM to a client who has schizophrenia. Available is haloperidol decanate injection 50 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Identify the Desired Dose and Available Concentration: Desired Dose: 75 mg of haloperidol decanoate Available Concentration: 50 mg/mL (This means there are 50 mg of haloperidol decanoate in every 1 mL of solution) Set up the Calculation: We need to find the volume (in mL) that contains the desired dose of 75 mg. We can use the following formula: Volume (mL) = Desired Dose (mg) / Available Concentration (mg/mL) Plug in the Values and Calculate: Volume (mL) = 75 mg / 50 mg/mL Volume (mL) = 1.5 mL Round to the Nearest Tenth : 1.5 mL
