Which of the following is NOT a category in the B-NICE mnemonic?

• A. Radiologic
• B. Biologic
• C. Nuclear
• D. Explosive

Answer: (A)

The idea behind the B-NICE mnemonic is to categorize the major threat types EMS responders plan for at mass‑casualty incidents. The categories it covers are Biological, Nuclear, Incendiary, Chemical, and Explosive. Radiologic isn’t included in this list, so Radiologic is the correct choice for what is NOT a category in B-NICE. This helps you focus on those five threat types when planning initial PPE, decontamination, and incident priorities under this mnemonic. If a radiologic threat is encountered, you’d apply radiological/nuclear response principles outside of B-NICE, rather than treating Radiologic as one of the B-NICE categories. The remaining options—Biologic, Nuclear, and Explosive—are explicitly part of B-NICE, so they belong in the mnemonic.
