A nurse is preparing to administer acetaminophen 56 mg PO to a newborn. Available is acetaminophen oral solution 160 mg/5 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.)

Formula: Dose to administer (mL) = (Ordered dose (mg) / Available dose (mg)) × Available volume (mL) Given: Ordered dose: 56 mg Available dose: 160 mg/5 mL Volume (mL) = (56 mg / 160 mg) × 5 mL = 0.35 × 5 mL = 1.75 mL Rounded to the nearest tenth: 1.8 mL. The nurse will administer 1.8 mL of acetaminophen.
