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.)
