Which action might indicate a decline in cognitive skills during an assessment of an older adult?

Choosing to highlight constant checking for correctness in actions as an indicator of decline in cognitive skills makes sense because it suggests an increased level of uncertainty and anxiety about tasks that were previously managed with confidence. This behavior can indicate a lack of trust in one's own cognitive processes, which may stem from difficulties in judgment, memory, or decision-making.

In older adults, a decline in cognitive skills can manifest as confusion or hesitation in everyday situations, where they may second-guess their decisions and actions. The need for reassurance or validation can highlight a struggle with cognitive processes that used to operate more smoothly, reflecting a decline in the ability to process information or make decisions independently.

The other options represent behaviors that typically indicate intact or robust cognitive functioning. For example, being able to hold a coherent conversation, quickly naming objects, and maintaining attention for extended tasks all reflect cognitive skills that are functioning well. Thus, while certain behaviors may signal cognitive decline, the act of constantly seeking correctness points specifically to an underlying cognitive struggle.
