A nurse is preparing to administer ceftriaxone 250 mg IM to a client. Available is ceftriaxone 500 mg powder. The package insert instructs reconstituting with 1 mL sterile water to yield ceftriaxone 350 mg/mL. How many mL of reconstituted solution should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
