Step-by-step explanation:
The most effective focus for intervention from an SLP for a nursing-home resident in a late stage of progressive dementia would be assisting in communication routines.
At this stage of dementia, the ability to engage in conversational speech, recall vocabulary, and comprehend social discourse may be severely impaired. However, assisting the resident in communication routines can help maintain functional communication abilities and enhance their overall quality of life.
For example, establishing a consistent communication routine, such as using visual supports or familiar gestures, can help the resident express their basic needs, make choices, and engage in simple conversations.
