Final answer:
A Certified Nursing Assistant should assist a resident with a weak side by positioning themselves on the weak side and having the resident move their strong side first during ambulation.
Step-by-step explanation:
When assisting a resident to ambulate who has a weak side, the Certified Nursing Assistant (CNA) should position themselves on the weak side of the resident and have the resident move their strong side first.
This practice ensures better support and balance for the resident during ambulation. It's essential that the CNA remains vigilant and ready to provide assistance if the resident begins to falter or lose balance, to prevent falls and ensure safety.
