A nurse is preparing to administer ceftriaxone 250 mg IM to an adult client who has a gonococcal infection. The label on the vial indicates to reconstitute each vial with 2.1 mL of sterile water to yield ceftriaxone 350 mg./mL. How many mL of the reconstituted medication should the nurse administer? (Round the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.)

Determine the total dosage: The client is prescribed 250 mg of ceftriaxone. Calculate the volume per dose: The ceftriaxone solution contains 350 mg per mL. The nurse needs to administer 250 mg per dose. To find the volume per dose: 350 mg / 1 mL = 250 mg / x mL 350x = 250 Dividing both sides by 350, we get: x = 0.714 mL Round the answer to the nearest hundredth: Rounding 0.714 to the nearest hundredth gives us 0.71 mL.
