A client with an extrapyramidal reaction receives a prescription for diphenhydramine 35 mg IM. The medication is supplied as 50 mg/mL in a 1 mL prefilled single use syringe. How many mL should the nurse give? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)

The nurse should administer 0.7 mL of diphenhydramine. Here's the calculation: Medication dosage: 35 mg (diphenhydramine) Medication concentration: 50 mg/mL (given on the syringe label) We need to find the volume (mL) containing the prescribed dose (35 mg) of diphenhydramine. Volume to administer (mL) = Dose (mg) / Concentration (mg/mL) Volume to administer (mL) = 35 mg / 50 mg/mL Volume to administer (mL) = 0.7 mL (round to nearest tenth) Therefore, the nurse should administer 0.7 mL of diphenhydramine
