A nursing instructor is teaching the class about community-based nursing. The instructor determines the session is successful when the students correctly choose which activity as an example of tertiary prevention?

By creating support groups that allow members to share strategies for living well.

Explanation:

Tertiary prevention is about reducing the impact of an ongoing illness or injury that has lasting effects on the patient. This can be done by helping people manage long-term health problems and injuries like chronic diseases, permanent impairments, just to mention a few in order to improve their ability to function, their quality of life and even their life expectancy.

Meaning that the support groups created by the nurses would serve as a medium for disseminating quality information about lifestyle improvements and also allows communication of ideas.
