    Calculation

    A nurse is preparing to administer ketorolac 15 mg IM every 6 hr PRN for pain to a client who is postoperative following a cesarean birth and reports pain. Available is ketorolac injection 30 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

    Volume (mL) = Dose (mg) / Concentration (mg/mL) Given: Dose = 15 mg Concentration = 30 mg/mL Volume = 15 mg / 30 mg/mL = 0.5 mL Therefore, the nurse should administer 0.5 mL of ketorolac.
