Category 9 · Within Safety & Infection Control of the exam
Emergency Preparedness & Bioterrorism
Recognizing and responding to biological, chemical, and radiological events, and the nurse's role in disaster response.
Client need · Safe and Effective Care Environment
Falls under Safety and Infection Control: emergency response planning, security plans, and protecting clients and staff from environmental hazards, including biological, chemical, and radiological events.
Learning objectives
- ✓Identify the Category A bioterrorism agents and their hallmark signs
- ✓Select the correct isolation precaution for each agent
- ✓Apply mass casualty triage categories (START) correctly
- ✓Describe decontamination steps and the nurse's surveillance and reporting role
- ✓Recognize chemical (nerve agent) and radiation exposure syndromes
3-day lesson plan
Day 1
Learn
Read the agent tables. Make flashcards: agent → key signs → precautions → treatment. Memorize SLUDGE and the triage colors.
Day 2
Apply
Practice triage scenarios: sort 10 mock victims into red/yellow/green/black. Drill which agents are person-to-person.
Day 3
Check
Take the lesson questions and a mixed safety quiz. Redo any missed triage or precaution items.
Study checklist
Category A agents at a glance
| Agent | Key signs | Precautions | Treatment |
|---|---|---|---|
| Anthrax (inhalation) | Flu-like illness → severe respiratory distress, widened mediastinum | Standard (not person-to-person) | Ciprofloxacin or doxycycline |
| Botulism | Descending flaccid paralysis, cranial nerve palsies | Standard (not contagious) | Antitoxin, ventilatory support |
| Pneumonic plague | Fever, cough, bloody sputum, rapid pneumonia | Droplet until 48–72 h of antibiotics | Streptomycin or doxycycline |
| Smallpox | Rash all in same stage, starts on face/extremities | Airborne + contact | Supportive; vaccination for contacts |
| Viral hemorrhagic fevers (e.g., Ebola) | Fever, bleeding, multisystem failure | Contact + droplet, strict PPE | Supportive care |
Mass casualty triage colors
| Color | Meaning | Example |
|---|---|---|
| Red — Immediate | Life-threatening but survivable with prompt care | Respiratory distress, uncontrolled bleeding |
| Yellow — Delayed | Serious but can wait | Stable fractures, burns without airway involvement |
| Green — Minimal | Walking wounded | Minor cuts and sprains |
| Black — Expectant | Deceased or injuries incompatible with survival given resources | Cardiac arrest in a mass casualty event |

Must know
- ●Only pneumonic plague and smallpox among the Category A agents spread person-to-person easily — know the isolation category for each.
- ●In a mass casualty event, do the greatest good for the greatest number: a client in cardiac arrest is tagged expectant (black), not immediate.
- ●Nerve agent exposure: remember SLUDGE and treat with atropine.
- ●An unusual cluster of similar severe illnesses should trigger reporting to infection control and public health — nurses are the front line of detection.
NCLEX tip
Smallpox lesions are all in the SAME stage; chickenpox lesions appear in DIFFERENT stages — a classic exam distinction.
