A nurse in an outpatient clinic is teaching a client who has a new prescription for oxycodone. Which of the following instructions should the nurse include in the teaching?

A. "You should take a stool softener while taking this medication.": Oxycodone is an opioid that commonly causes constipation by slowing gastrointestinal motility. Taking a stool softener or other bowel regimen helps prevent discomfort and promotes regular bowel movements. B. "You should minimize exposure to sunlight while taking this medication.": Photosensitivity is not a typical adverse effect of oxycodone. Limiting sun exposure is unnecessary unless the client is taking other medications that increase photosensitivity. C. "You should take this medication on an empty stomach.": Oxycodone can be taken with or without food. Taking it on an empty stomach may increase gastrointestinal discomfort rather than improve absorption. D. "You might urinate more frequently while taking this medication.": Opioids like oxycodone often cause urinary retention, not increased urination. This statement does not reflect the expected pharmacologic effect.
