A nurse is preparing to administer haloperidol 3 mg IM. Available is haloperidol injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Determine the desired dosage: The nurse needs to administer 3 mg of haloperidol. Determine the volume per dose: The haloperidol injection contains 5 mg per 1 mL. The nurse needs to administer 3 mg per dose. To find the volume per dose: 5 mg / 1 mL = 3 mg / x mL Cross-multiplying gives us: 5x = 3 Dividing both sides by 5, we get: x = 0.6 mL
