Calculation
A nurse is preparing to administer hydrocortisone 60 mg IV bolus to a child. The amount available is hydrocortisone 100 mg powder. Reconstituting with 2 mL of bacteriostatic water yields hydrocortisone 50 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
mL
Explanation & Rationale
Calculation: Desired dose = 60 mg. Determine the concentration of the medication after reconstitution. The reconstituted concentration is 50 mg/mL. Calculate the volume in milliliters (mL) to administer. Volume (mL) = Desired dose (mg) / Concentration (mg/mL) = 60 mg / 50 mg/mL = 1.2 mL.
