Correct Answer is A

Explanation

A. This option is correct. Rehabilitative care often involves educating the primary caregiver on how to assist the client in their recovery process.

C. This option refers to the initiation of services, which may not specifically pertain to rehabilitative care.

D. This option incorrectly associates rehabilitative care exclusively with long-term care facilities. While rehabilitative care may occur in such facilities, it can also occur in other settings.

B. Vitamin E is an antioxidant that helps protect cells from damage. While it is important for overall health, it is not specifically known for wound healing.

C. Folate (also known as vitamin B9) is essential for DNA synthesis and repair, as well as cell division. It is important for overall health, but it is not as directly associated with wound healing as vitamin C.
