Final answer:
The last sense to leave a dying patient is hearing.
Step-by-step explanation:
The last sense to leave a dying patient is hearing. When someone is unconscious or in a coma, they may not be able to respond to touch, see, or smell, but studies have shown that even when unconscious, patients can still hear and process sounds around them. This means that the person providing palliative care should continue to speak to the patient, offer reassurance, and provide comfort through soothing words.
