Question 1 of 5
A nurse has had contact with a patient who developed smallpox and became febrile after a terrorist attack. This nurse will require what treatment?
Correct Answer: C
Rationale: Vaccination within 4 days of smallpox exposure prevents infection in contacts. Waiting, CSFs, or antibiotics are ineffective.
Question 2 of 5
The emergency response team is dealing with a radiation leak at the hospital. What action should be performed to prevent the spread of the contaminants?
Correct Answer: D
Rationale: Sealing air ducts and vents prevents radiation spread through ventilation. Bleach, incineration, or ventilation deactivation are less effective.
Question 3 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 4 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 5 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.
