A nurse is preparing to administer haloperidol 0.5 mg by mouth to an older adult client. The amount available is haloperidol oral concentrate 2 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the amount of haloperidol oral concentrate the nurse should administer, we can use the following equation: Volume (mL) = Dose (mg) / Concentration (mg/mL) In this case, the dose is 0.5 mg and the concentration of the haloperidol oral concentrate is 2 mg/mL. Volume (mL) = 0.5 mg / 2 mg/mL Volume (mL) = 0.25 mL
