A child weighing 67 pounds (30.5 kg) receives a prescription for benztropine 0.61 mg intravenous (IV) every 12 hours. This medication is available as 1 mg/mL ampules. How many mL should the nurse administer? (Enter the numeric value only. If rounding is required, round to the nearest hundredth.)

The calculation for this question involves converting the prescribed dose from milligrams (mg) to millilitres (mL) using the available concentration of the medication. Given: Prescribed dose of benztropine: 0.61 mg Medication concentration: 1 mg/mL To calculate the volume (mL) to administer, use the formula: Volume (mL) = Prescribed dose (mg) / Medication concentration (mg/mL) Volume (mL) = 0.61 mg / 1 mg/mL = 0.61 mL Therefore, the nurse should administer 0.61 mL of benztropine.
