What does the acronym RASS stand for?

• A. Richmond Agitation Sedation Scale
• B. Rapid Assessment of Sedation Score
• C. Respiratory Assessment for Sedation Scale
• D. Rating of Anxious Sedation Scale

Answer: (A)

The key idea here is recognizing the name of the ICU scale used to rate a patient’s level of arousal and agitation to guide sedation. The correct expansion is Richmond Agitation Sedation Scale. In practice, clinicians use this scale to determine how awake or calm a patient is, which helps tailor sedation to light levels and avoid deep or oversedation. The scale ranges from positive values indicating agitation to a zero or negative values indicating varying degrees of sedation, with specific descriptors for each level. This standardization makes communication and titration more precise among the care team.

The other phrases don’t correspond to the established ICU tool: they either describe a nonstandard or incorrect concept or mix respiratory or anxious factors with sedation, rather than the validated Richmond Agitation Sedation Scale.
