A nurse is preparing to administer hydrocortisone 100 mg IM daily to a client. Available is hydrocortisone 250 mg/2 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Calculation: Identify the ordered dose and available concentration Ordered Dose: 100 mg Available Concentration: 250 mg/2 mL Convert concentration to mg/mL 250 mg ÷ 2 mL = 125 mg/mL Calculate the volume to administer Volume (mL) = Ordered Dose ÷ Concentration Volume = 100 ÷ 125 = 0.8 mL
