A nurse is preparing to administer risperidone 1.5 mg PO every 12 hr to a client who has schizophrenia. Available is risperidone solution 1 mg/mL. What is the total daily dose in mL the nurse should administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

tep-by-Step Solution Understanding the Problem The client needs risperidone 1.5 mg every 12 hours. We have risperidone solution 1 mg/mL. We need to find the total daily dose in mL. Step 1: Calculate the total daily dose in mg The client receives 1.5 mg every 12 hours. There are 2 doses in a day (every 12 hours). So, the total daily dose in mg is 1.5 mg/dose X 2 doses = 3 mg. Step 2: Convert mg to mL We know that 1 mg of risperidone is in 1 mL of solution. We have a total daily dose of 3 mg. So, to find the volume in mL, we can set up a proportion: 1 mg / 1 mL = 3 mg / x mL Step 3: Solve for x Cross-multiply: 1 mg X x mL = 1 mL X 3 mg Simplify: x mL = 3 mL Therefore, the nurse should administer a total daily dose of 3 mL.
