    A patient on chronic Dilaudid (hydromorphone) therapy tests negative for opioids on a urine drug screen. The patient claims to be using medicine as prescribed. The appropriate next step would be to:

  3. Taper and discontinue opioid therapy

  4. Refer the patient to a detoxification/rehabilitation program

  5. Notify law enforcement

Answer choice from original test was changed from hydromorphone to oxycodone, because hydromorphone is now a recognized metabolite of morphine and heroin [8].
