A nurse is providing teaching to a client who has a new prescription for hydrocodone for pain management. Which of the following instructions should the nurse include?

The correct answer is A: Increase dietary fiber to prevent constipation. Hydrocodone is an opioid analgesic that can cause constipation as a common side effect. Increasing dietary fiber can help prevent constipation by promoting regular bowel movements. The other options are incorrect because: B: Grapefruit juice can actually inhibit the absorption of many medications, including hydrocodone. C: Driving restrictions are not necessary with hydrocodone unless the client experiences drowsiness or dizziness. D: Hydrocodone is a central nervous system depressant, so it is more likely to cause drowsiness or sedation rather than increased energy levels.
