A healthcare provider is assessing the pain level of a client who has dementia and difficulty communicating. Which pain assessment technique should the healthcare provider use?

In clients with dementia and difficulty communicating, using behavioral indicators such as agitation and restlessness is more reliable for assessing pain than relying on verbal self-report, pain scales, or observing facial expressions. Verbal self-report may not be possible due to communication challenges, pain scales may be difficult for the client to comprehend, and observing facial expressions alone may not provide a comprehensive assessment of pain in individuals with dementia.
