    Calculation

    A nurse is preparing to administer acetaminophen 320 mg PO every 4 hr PRN for pain. The amount available is acetaminophen liquid 160 mg/5 mL. How many mL should the nurse administer per dose? Round the answer to the nearest tenth and use a leading zero if it applies. Do not use a trailing zero.

    ml

    Explanation & Rationale

    Step 1 is 320 mg ÷ 160 mg × 5 mL. Step 2 is 2 × 5 mL. Step 3 is 10.0 mL. The final calculated answer is 10 mL.
