A nurse is preparing to administer haloperidol lactate 12 mg PO for a client who has schizophrenia and who cannot swallow tablets. Available is haloperidol 2 mg/mL oral solution. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies.)

Step 1 is to determine the amount of haloperidol lactate that needs to be administered, which is 12 mg. Step 2 is to calculate the volume of the haloperidol oral solution needed to deliver this dose. This is done using the formula: Dose (mg) ÷ Concentration (mg/mL) Given that the available concentration is 2 mg/mL, we calculate: 12 mg ÷ 2 mg/mL = 6 mL Therefore, the nurse should administer 6 mL of the haloperidol oral solution.
