While at the scene of an incident in which several patients were possibly exposed to lewisite, you are informed that an unresponsive patient with multiple blisters on his body and inadequate breathing is being brought to you for treatment. You should:
- have the appropriate antidote ready and notify the burn center of the situation.
- don the appropriate personal protective equipment to avoid cross-contamination.
- prepare your intubation equipment and set up two IV lines of normal saline.
- ensure that the patient has been decontaminated before initiating any treatment.
ensure that the patient has been decontaminated before initiating any treatment.
What do tabun, sarin, soman, and VX agent all have in common?
- They all enter the body through the respiratory tract.
- They all possess the same level of volatility and persistence.
- The onset of symptoms following exposure is immediate.
- They are all colorless and odorless chemical nerve agents.
The onset of symptoms following exposure is immediate.
Sarin has an LD50 of 1,700 mg/70 kg. This means that:
- 50% of this dose will kill most people who are exposed to it.
- all people older than 50 years of age will die from this dose.
- this dose will kill 50% of people who are exposed to it.
- most people younger than 50 years of age will survive this dose.
this dose will kill 50% of people who are exposed to it.
The hazardous materials team has deemed it safe for you to enter and remove patients from an office building that exploded. As you are moving the patients, it is most important to:
- remain alert to the possibility of a secondary explosive device.
- provide only immediate lifesaving care inside the building.
- quickly identify the patients who appear to be the most critical.
- get them out of the building before you begin the triage process.
remain alert to the possibility of a secondary explosive device.
You are at the scene of an explosion at an office complex. There are a total of 15 casualties, including 2 deaths. In addition to injuries experienced by the explosion, most of the victims are complaining of nausea, vomiting, and diarrhea. When caring for any of these victims, you must:
- recall that a dirty bomb does not cause radiation contamination.
- ensure that they have been properly decontaminated first.
- wear a lead shield or apron to protect yourself adequately.
- immediately treat those with life-threatening injuries.
ensure that they have been properly decontaminated first.
In contrast to volatile chemical agents, nonvolatile chemical agents:
- include sarin and will turn from liquid to gas within seconds to minutes.
- include all nerve gases and remain in the environment for weeks to months.
- can remain on surfaces for long periods of time, usually longer than 24 hours.
- evaporate fast when left on a surface in the optimal temperature range.
can remain on surfaces for long periods of time, usually longer than 24 hours.

Oklahoma City bombing
Which of the following is/are the fastest and most powerful form of radiation and can easily penetrate through lead?
- Gamma rays
- Neutron energy
- Beta rays
- Alpha rays

The likelihood of a nuclear attack on the United States is:
- high, because many other nations have developed nuclear weapons and are able to deliver them via a missile.
- remote, because other nations do not have the ability to deliver a nuclear weapon via missile or bomb.
- impossible, because no other nations have the resources or funding to build an effective nuclear weapon.
- probable, because the whereabouts of many small nuclear devices from the former Soviet Union is unknown.
remote, because other nations do not have the ability to deliver a nuclear weapon via missile or bomb.
A terrorist would most likely disseminate smallpox via:
- aerosolization.
- an explosion.
- a dirty bomb.
- a powder.
aerosolization.
Biologic agents are:
- synthetically manufactured and weaponized by mixing the synthetic component with an organism.
- naturally occurring organisms that are cultivated, synthesized, and mutated in a laboratory.
- the ideal weapons of mass destruction if the terrorist’s objective is to affect a small geographic area.
- least preferred by terrorists because they are difficult to disseminate over a large population.
naturally occurring organisms that are cultivated, synthesized, and mutated in a laboratory.
Which of the following should make you the most suspicious of a terrorist attack or an incident involving a weapon of mass destruction?
