Disaster Nursing - 2026 Emergency Response: Practice Test 2
(Units 8-13) - Questions with Correct Answers
100 questions
1. A radiological dispersal device ("dirty bomb"):
A. Is a nuclear detonation
B. Causes mass radiation deaths in all cases
C. Combines conventional explosives with radioactive material, with most casualties caused by
the blast
D. Contains no explosives
Correct Answer: C. Combines conventional explosives with radioactive material, with most
casualties caused by the blast
Rationale: Radiation doses are usually low. Fear and contamination concerns are major issues.
2. Pregnant staff caring for radioactively contaminated patients:
A. Can be reassigned when possible, though risk from standard precautions is low
B. Must always care for them
C. Face high risk always
D. Have no considerations
Correct Answer: A. Can be reassigned when possible, though risk from standard precautions is
low
Rationale: Fetal dose limits are lower. Reassignment reduces concern.
3. The radiation trefoil symbol indicates:
A. Biological hazard
B. Chemical hazard
C. The presence of radiation or radioactive material
D. Fire hazard
Correct Answer: C. The presence of radiation or radioactive material
Rationale: Recognizing symbols helps identify hazards. Biohazard symbols differ.
,4. A nuclear detonation causes:
A. Only noise
B. Only contamination
C. Blast, thermal burns, prompt radiation and radioactive fallout
D. No injuries
Correct Answer: C. Blast, thermal burns, prompt radiation and radioactive fallout
Rationale: Sheltering in place reduces fallout exposure. "Get inside, stay inside, stay tuned" is
the guidance.
5. The Radiation Emergency Assistance Center/Training Site (REAC/TS) provides:
A. Radiation therapy
B. 24/7 expert consultation on radiation emergencies
C. Nuclear power
D. Billing support
Correct Answer: B. 24/7 expert consultation on radiation emergencies
Rationale: It is operated for the US Department of Energy. Clinicians can call for guidance.
6. Personal dosimeters worn by responders:
A. Protect against radiation
B. Detect chemicals
C. Measure the cumulative radiation dose received
D. Measure heart rate
Correct Answer: C. Measure the cumulative radiation dose received
Rationale: Dose limits guide work time. Records are maintained.
,7. Radiation population monitoring centers after an incident provide:
A. Screening for contamination, decontamination and registry of affected people
B. Surgery
C. Radiation therapy
D. Billing
Correct Answer: A. Screening for contamination, decontamination and registry of affected
people
Rationale: Community reception centers reduce hospital crowding. Public health leads them.
8. Nuclear power plant emergency planning zones extend about:
A. 1 mile
B. 100 feet
C. 500 miles
D. 10 miles for plume exposure and 50 miles for ingestion pathway
Correct Answer: D. 10 miles for plume exposure and 50 miles for ingestion pathway
Rationale: Planning zones guide evacuation and food controls. KI may be distributed within
zones.
9. Nurses caring for patients after radiation exposure should anticipate:
A. No complications
B. Immediate recovery
C. Only skin issues
D. Infection risk from immunosuppression, bleeding risk and fluid and electrolyte needs
Correct Answer: D. Infection risk from immunosuppression, bleeding risk and fluid and
electrolyte needs
Rationale: Neutropenic precautions may be required. Supportive care improves survival.
, 10. Radiation Emergency Medical Management (REMM) is:
A. An HHS online resource providing guidance on diagnosis and treatment of radiation injuries
B. A treatment drug
C. A dosimeter
D. A shelter
Correct Answer: A. An HHS online resource providing guidance on diagnosis and treatment of
radiation injuries
Rationale: It includes dose estimation tools. Clinicians use it during events.
11. After a nuclear detonation, the public is advised to:
A. Drive away immediately
B. Go outside to look
C. Get inside a sturdy building, stay inside and stay tuned for instructions
D. Stand by windows
Correct Answer: C. Get inside a sturdy building, stay inside and stay tuned for instructions
Rationale: Fallout is most dangerous in the first hours. Interior rooms provide the best
protection.
12. Colony-stimulating factors such as filgrastim are used in ARS to:
A. Remove radioactive material
B. Block thyroid uptake
C. Treat burns
D. Stimulate white blood cell recovery
Correct Answer: D. Stimulate white blood cell recovery
Rationale: Several are FDA-approved for hematopoietic ARS. Early use is recommended.
