Answer:
a) "You must avoid hyperextending your neck after surgery."
Step-by-step explanation:
After this type of surgery, it’s important to rest.
If a person expands their neck, the wound might take more time to heal or maybe cause additional problems, like infection, heavy bleeding or something else.
It might take some time, but at least, a person will feel safe and it will take less time to heal before they can get back to their regular activities.
