Mental instability is associated with which code?

• A. Code 18
• B. Code 19
• C. Code 20
• D. Code 21

Answer: (B)

This item hinges on recognizing the quick-communication code used to flag mental status during response operations. When someone is mentally unstable, the corresponding code is Code 19. Using this label immediately signals responders to initiate mental-health assessment and safety precautions, ensuring rapid involvement of trained personnel and appropriate actions to protect everyone involved. It directs the next steps—such as monitoring the person, removing hazards, and contacting medical staff—so they can address the situation without delay. Other codes point to different conditions and trigger their own procedures, which is why Code 19 is the correct match for mental instability.
