Nerve agents produce their effect by interfacing with normal transmission of nerve impulses.
Correct Answer
A. TRUE
Explanation
Nerve agents are highly toxic substances that interfere with the normal transmission of nerve impulses in the body. They inhibit the activity of an enzyme called acetylcholinesterase, which is responsible for breaking down the neurotransmitter acetylcholine. By inhibiting this enzyme, nerve agents cause an excessive accumulation of acetylcholine in the synapses, leading to overstimulation of the nervous system. This disruption in nerve impulse transmission can result in a wide range of symptoms, including paralysis, convulsions, respiratory failure, and even death. Therefore, the statement that nerve agents produce their effect by interfacing with normal transmission of nerve impulses is true.

This characteristic is important in various contexts, such as warfare or pest control, where the agent needs to have a lasting impact on the target. Lethality refers to the ability to cause death, volatility refers to the tendency to evaporate or vaporize quickly, and permeability refers to the ability to pass through or penetrate a substance.
4.
Inhalation of nerve gas characteristically results in which of the symptoms listed below?
Correct Answer
C. Pinpoint pupils
Explanation
Inhalation of nerve gas can cause pinpoint pupils as one of the symptoms. This is because nerve gases, such as sarin or VX, can affect the autonomic nervous system and disrupt the normal functioning of the pupils. Pinpoint pupils, also known as miosis, occur when the muscles in the iris constrict, causing the pupil to become very small. This symptom is a result of the nerve gas interfering with the neurotransmitters that regulate pupil size, leading to a constricted or pinpoint appearance.
5.
In a definitive care facility, the indicated treatment of a nerve agent victim includes which of the following therapies?

First aid treatment for blood agents is amyl nitrite ampules followed by which of the compounds listed below?
Correct Answer
D. Intravenous sodium thiosulfate
Explanation
The correct answer is intravenous sodium thiosulfate. Blood agents are toxic substances that interfere with the body's ability to use oxygen, such as cyanide. Amyl nitrite ampules are used as a first aid treatment to help counteract the effects of blood agents. However, amyl nitrite alone is not sufficient, and it needs to be followed by the administration of intravenous sodium thiosulfate. Sodium thiosulfate helps to detoxify cyanide by converting it into a less toxic form that can be eliminated from the body. Oral potassium chloride and oral sodium thiosulfate are not as effective as intravenous administration in treating blood agents.
