When performing an across-the-room assessment, the triage nurse primarily uses:
B. Sight and hearing.
In an across-the-room assessment, the nurse observes the patient from a distance and relies on their visual perception to assess physical appearance, behavior, signs of distress, and any obvious abnormalities. Hearing is also used to gather information about the patient's speech, breathing sounds, or any audible cues that may indicate potential issues. The nurse does not typically rely on touch, taste, or smell during an across-the-room assessment.
