Which scale is commonly used to assess agitation in critically ill patients?

• A. Ramsey Scale
• B. Glasgow Scale
• C. Reaction Level Scale
• D. Riker Sedation-Agitation Scale

Answer: (D)

In critical care, you need a simple, reliable way to quantify how agitated or sedated a patient is so you can titrate meds and monitor changes. The Riker Sedation-Agitation Scale (RASS) does this best because it covers the full spectrum—from combative agitation to deep unresponsiveness—and is quick to apply at the bedside. This makes it ideal for guiding sedation targets and ensuring consistent assessment across caregivers. It’s also well-validated in ICU populations, supporting consistent decision-making. By contrast, the Ramsey scale focuses mainly on sedation depth without capturing agitation, the Glasgow Coma Scale assesses neurological status and level of consciousness rather than agitation specifically, and the Reaction Level Scale is less commonly used in ICU practice for ongoing sedation–agitation management.
