A nurse is preparing to administer haloperidol lactate 7 mg PO to a client who has psychosis. Available is haloperidol lactate 2 mg/mL oral solution. How many mL should the nurse plan to administer? (Round to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Step 1: Identify the dose prescribed. Prescribed dose = 7 mg Step 2: Identify the concentration of the available medication. Available concentration = 2 mg per 1 mL Step 3: Determine the volume needed using division. Volume needed = prescribed dose ÷ concentration Volume needed = 7 mg ÷ (2 mg ÷ 1 mL) Step 4: Perform the division. 7 ÷ 2 = 3.5 Step 5: State the final answer with correct rounding and formatting. The nurse should administer 3.5 mL.
