Which code indicates a medical emergency?

• A. Code 100
• B. Code Black
• C. Code Blue
• D. Code Red

Answer: (A)

A medical emergency notification is a signal that summons the rapid-response team to a patient in immediate danger and prompts immediate lifesaving actions. In this set of codes, the option described as that medical emergency alert is the one that should be activated right away, which is why it’s the best choice. It directly signals the need for urgent medical intervention.

Context helps: Code Red typically means fire, Code Black can indicate a security threat or other disaster, and in many places Code Blue signals a medical emergency too. But the exact meaning of codes can vary by facility, so the correct option here is the one that corresponds to the medical emergency alert within this particular coding scheme.
