Question 1 of 5
A group of medical nurses are being certified in their response to potential bioterrorism. The nurses learn that if a patient is exposed to the smallpox virus he or she becomes contagious at what time?
Correct Answer: C
Rationale: Smallpox patients become contagious when a rash appears, typically on the face and forearms, not immediately or only with pustules or fever.
Question 2 of 5
A patient is being treated in the ED following a terrorist attack. The patient is experiencing visual disturbances, nausea, vomiting, and behavioral changes. The nurse suspects this patient has been exposed to what chemical agent?
Correct Answer: A
Rationale: Nerve agents cause neurological symptoms like visual disturbances, nausea, and behavioral changes due to acetylcholinesterase inhibition.
Question 3 of 5
A patient is admitted to the ED who has been exposed to a nerve agent. The nurse should anticipate the STAT administration of what drug?
Correct Answer: D
Rationale: Atropine counteracts nerve agent effects by blocking acetylcholine, alleviating hyperstimulation symptoms. Other drugs are for different agents or ineffective.
Question 4 of 5
A patient was exposed to a dose of more than 5,000 rads of radiation during a terrorist attack. The patients skin will eventually show what manifestation?
Correct Answer: D
Rationale: High radiation doses (>5,000 rads) cause skin necrosis within days to months. Lower doses cause erythema or desquamation, and ecchymosis is unrelated.
Question 5 of 5
There has been a radiation-based terrorist attack and a patient is experiencing vomiting, diarrhea, and shock after the attack. How will the patients likelihood of survival be characterized?
Correct Answer: C
Rationale: Symptoms like vomiting, diarrhea, and shock indicate high radiation exposure (>800 rads), making survival improbable due to severe systemic damage.
