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

Given: Ordered dose of hydrocortisone: 100 mg Concentration of hydrocortisone: 250 mg/2 mL Step 1: Set up the proportion: Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL) Step 2: Substitute the values: 100 mg / Volume = 250 mg/2 mL Step 3: Solve for the unknown volume: Volume = 100 mg / (250 mg/2 mL) Volume = 100 mg x (2 mL / 250 mg) Volume = 0.8 mL
