A nurse is preparing to administer risperidone 25 mg IM to an older adult client who has schizophrenia. Available is risperidone injection 25 mg/2 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero fit applies. Do not use a trailing zero.)

Identify the Desired Dose and Available Concentration: Desired Dose: 25 mg of risperidone Available Concentration: 25 mg/2 mL (This means there are 25 mg of risperidone in every 2 mL of solution) Set up the Calculation: We need to find the volume (in mL) that contains the desired dose of 25 mg. We can use the following formula: Volume (mL) = (Desired Dose (mg) / Available Concentration (mg)) x Volume of Available Solution (mL) Plug in the Values and Calculate: Volume (mL) = (25 mg / 25 mg) x 2 mL Volume (mL) = 1 x 2 mL Volume (mL) = 2 mL Round to the Nearest Whole Number : 2 mL
