Final answer:
Patients who have advance directives may receive pain medication when needed.
Step-by-step explanation:
The statement 'Patients who have advance directives may receive pain medication when it is needed' is True.
Advance directives are legal documents that allow individuals to express their healthcare preferences and make decisions about their medical treatment in case they become unable to communicate their wishes. These documents include information about pain management and the use of pain medication.
Healthcare providers need to honor the patient's wishes as outlined in their advance directives, including providing pain medication when necessary.
