What is the primary purpose of using the RASS in ICU care and PT planning?

• A. To diagnose delirium
• B. To guide sedation and activity planning
• C. To monitor nutrition
• D. To track infection

Answer: (B)

The main idea behind using the RASS is to quantify how awake or agitated a patient is so you can tailor sedation and plan rehabilitation. In the ICU, the level of arousal directly affects safety and participation in physical therapy. If a patient is too agitated, they may disrupt therapy or require restraint; if they’re too deeply sedated, they won’t cooperate or benefit from mobilization. By assigning a standardized level of agitation or sedation, clinicians can titrate medications to reach a light, cooperative state that permits safe and effective therapy sessions. This makes PT planning more precise and consistent across the care team.

RASS isn’t a tool for diagnosing delirium, which is assessed with other screens, and it isn’t used to monitor nutrition or track infection. The emphasis here is on guiding sedation to optimize movement and participation in rehab.
