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 sterile water 2.1 mL to yield ceftriaxone 350 mg/mL. How many mL of the reconstituted medication should the nurse administer? (Round the answer to the nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.) ________ mL

Step 1 is to identify the ordered dose and the available concentration Ordered Dose: 250 mg Available Concentration: 350 mg / 1 mL Step 2 is to calculate the volume to administer in milliliters (mL) Volume = (Ordered Dose ÷ Available Dose) × Available Volume Volume = (250 ÷ 350) × 1 250 ÷ 350 = 0.7142... 0.7142... × 1 = 0.7142... Step 3 is to round to the nearest hundredth 0.7142... ≈ 0.71 Answer: 0.71 mL
