Which of the following is not a key measure in the assessment of critically injured patients for delirium prevention?

Providing entertainment is not considered a key measure in the assessment of critically injured patients for delirium prevention. The focus in managing critically injured patients is on addressing their medical, psychological, and environmental needs to minimize the risk of delirium.

Regular exercise improves physical status and can play a significant role in preventing physical complications that might exacerbate cognitive issues. Effective communication is vital in ensuring that patients understand and are engaged in their care, which is important for cognitive function. Environment modification, such as reducing noise, ensuring proper lighting, and maintaining a familiar surroundings, is critical for creating a calm setting that can help prevent confusion and agitation.

In contrast, while providing entertainment may help ease boredom or anxiety, it does not directly address the underlying factors that contribute to the development of delirium in critically injured patients. Therefore, it is not seen as a fundamental measure in delirium prevention protocols.
