A nurse is preparing to administer hydrocodone/acetaminophen 5 mg PO every 6 hr for pain. The amount available is hydrocodone/acetaminophen 7.5 mg/500 mg/15 mL elixir. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero. )

Identify the desired dose and the available concentration: Desired dose: 5 mg of hydrocodone Available concentration: 7.5 mg of hydrocodone in 15 mL of elixir Calculate the volume needed for the desired dose using the formula: Volume (mL)=(Desired dose (mg)/Available concentration (mg/mL)) Determine the available concentration in mg/mL: Available concentration=(7.5 mg/15 mL)=0.5 mg/mL Calculate the volume needed for a 5 mg dose: Volume (mL)=(5 mg/0.5 mg/mL)=10 mL
