Q

anthrax

A

A disease caused by deadly bacteria (Bacillus anthracis) that lay dormant in a spore (protective shell); the germ is released from the spore when exposed to the optimal temperature and moisture. The routes of entry are inhalation, cutaneous, and gastrointestinal (from consuming food that contains spores).

A

The area of the lymphatic system where infection-fighting cells are housed

28

A

A passive circulatory system that transports a plasmalike liquid called lymph, a thin fluid that bathes the tissues of the body

29
Q

Mark 1 Nerve Agent Antidote Kit (NAAK)

A

A nerve agent antidote kit containing two auto-injectors containing atropine and pralidoxime chloride

30
Q

miosis

A

Excessively constricted pupil; often bilateral after exposure to nerve agents

31
Q

mutagen

A

A substance that mutates, damages, and changes the structure of DNA in the body’s cells

32
Q

nerve agents

A

A class of chemical called organophosphates; they function by blocking an essential enzyme in the nervous system, which causes the body’s organs to become overstimulated and burn out

33
Q

neurotoxins

A

Biologic agents that are the most deadly substances known to humans; they include botulinum toxin and ricin

34
Q

neutron radiation

A

The type of energy that is emitted from a strong radiologic source; neutron particles are among the most powerful forms of radiation. Neutrons easily penetrate through lead and require several feet of concrete to stop them.

Q

off-gassing

A

The emitting of an agent after exposure, for example from a person’s clothes that have been exposed to the agent

36
Q

persistency

A

Term used to describe how long a chemical agent will stay on a surface before it evaporates

37
Q

phosgene

A

A pulmonary agent that is a product of combustion, such as might be produced in a fire at a textile factory or house or from metalwork or burning Freon. Phosgene is a very potent agent that has a delayed onset of symptoms, usually hours.

38
Q

phosgene oxime (CX)

A

A blistering agent that has a rapid onset of symptoms and produces immediate, intense pain and discomfort on contact

39
Q

pneumonic plague

A

A lung infection, also known as plague pneumonia, that is the result of inhalation of plague-causing bacteria

The monitoring, usually by local or state health departments, of patients presenting to emergency departments and alternative care facilities, the recording of EMS call volume, and the use of over-the-counter medications

55
Q

tabun (GA)

A

A nerve agent that is one of the G agents; is 36 times more persistent than sarin and approximately half as lethal; has a fruity smell and is unique because the components used to manufacture the agent are easy to acquire and the agent is easy to manufacture

56
Q

tertiary blast injury

A

An injury from whole body displacement and subsequent traumatic impact with environmental objects

A

One of the G agents; it is a clear oily agent that has no odor and looks like baby oil; more than 100 times more lethal than sarin and is extremely persistent

58
Q

vapor hazard

A

An agent that enters the body through the respiratory tract

59
Q

viral hemorrhagic fevers (VHF)

A

A group of diseases caused by viruses that include the Ebola, Rift Valley, and yellow fevers, among others. This group of viruses causes the blood in the body to seep out from the tissues and blood vessels.

Q

viruses

A

Germs that require a living host to multiply and survive

61
Q

volatility

A

A term used to describe how long a chemical agent will stay on a surface before it evaporates

Q

weapon of mass casualty (WMC)

A

Any agent designed to bring about mass death, casualties, and/or massive damage to property and infrastructure (bridges, tunnels, airports, and seaports); also known as a weapon of mass destruction (WMD)

63
Q

weapon of mass destruction (WMD)

A

Any agent designed to bring about mass death, casualties, and/or massive damage to property and infrastructure (bridges, tunnels, airports, and seaports); also known as a weapon of mass casualty (WMC)

64
Q

A

The creation of a weapon from a biologic agent generally found in nature and that causes disease; the agent is cultivated, synthesize, and/or mutated to maximize the target population’s exposure to the germ
