Chapter 73 : Terrorism, Mass Casualty, and Disaster Nursing Questions
Question 1 of 5
A patient has been exposed to a nerve agent in a biochemical terrorist attack. This type of agent bonds with acetylcholinesterase, so that acetylcholine is not inactivated. What is the pathologic effect of this type of agent?
Correct Answer: A
Rationale: Nerve agents cause continuous nerve hyperstimulation by preventing acetylcholine breakdown. Deactivation, binding, or destruction do not occur.
Question 2 of 5
A group of military nurses are reviewing the care of victims of biochemical terrorist attacks. The nurses should identify what agents as having the shortest latency?
Correct Answer: B
Rationale: Nerve agents produce symptoms within seconds, having the shortest latency. Viral, pulmonary, and blood agents have longer latency periods.
Question 3 of 5
A nurse is giving an educational class to members of the local disaster team. What should the nurse instruct members of the disaster team to do in a chemical bioterrorist attack?
Correct Answer: C
Rationale: Most chemical agents are heavier than air, so standing up minimizes exposure. Covering eyes, masking, or crawling increases exposure risk.
Question 4 of 5
The nurse manager in the ED receives information that a local chemical plant has had a chemical leak. This disaster is assigned a status of level II. What does this classification indicate?
Correct Answer: B
Rationale: Level II disasters require regional support as local resources are overwhelmed, but state or federal aid is not typically needed. Evacuation is not inherently indicated by this level.
Question 5 of 5
A workplace explosion has left a 40-year-old man burned over 65% of his body. His burns are second- and third-degree burns, but he is conscious. How would this person be triaged?
Correct Answer: D
Rationale: Extensive burns over 65% of the body indicate a low survival likelihood, warranting a black triage tag to prioritize resources for those with better prognosis.
