A nurse is investigating a mumps outbreak among school-age children.
Using the epidemiological triangle, the nurse should identify which of the following as the host?
The virus.
The vaccine.
The school.
The children.
The Correct Answer is D
Choice A rationale
In the epidemiological triangle, the virus is considered the agent, not the host.
Choice B rationale
The vaccine is a form of intervention to prevent the disease, not the host.
Choice C rationale
The school could be considered the environment in which the host (the children) and the agent (the virus) interact, but it is not the host itself.
Choice D rationale
This is the correct answer. In the context of a mumps outbreak among school-age children, the children are the hosts. They are the ones who can become infected with the mumps virus.

Correct Answer is B
Explanation
Choice A rationale
While manic behavior can be disruptive and may require intervention, it is not typically life- threatening. Therefore, this client would not be the highest priority in a triage situation following a bombing incident.
Choice B rationale
A rigid abdomen with manifestations of shock could indicate serious internal injuries, such as bleeding or organ damage. This client would be a high priority for treatment due to the potential for rapid deterioration and life-threatening complications.
Choice C rationale
Superficial partial thickness burn injuries over 5% of the body, while painful and requiring treatment, are not typically immediately life-threatening. This client would be a lower priority compared to a client with signs of shock and potential internal injuries.
Choice D rationale
A femur fracture with a 2+ pedal pulse indicates that the client has a serious injury, but it is not immediately life-threatening. The presence of a 2+ pedal pulse suggests that circulation to the foot is still intact. This client would be a lower priority compared to a client with signs of shock and potential internal injuries.
Correct Answer is D
Explanation
Choice A rationale
Evaluating the effectiveness of local disaster-preparedness drills is an important step in disaster management. However, it is not the first action to take when developing a disaster- preparedness plan. This step usually comes later, after identifying the community’s risks and capabilities, assembling a team, and providing education.
Choice B rationale
Assembling an emergency disaster response team is crucial in disaster management. However, before assembling a team, it is important to first identify the community’s risks and capabilities. This will help in determining the composition and roles of the team members.
Choice C rationale
Providing education about first aid and triage is an essential part of disaster preparedness. However, this is not the first step. Before providing education, it is important to first understand the community’s risks and capabilities.
Choice D rationale
Identifying the community’s risks and capabilities is the first action to take when developing a disaster-preparedness plan. This involves determining what natural disasters the community is likely to face and the community’s capacity to respond to these disasters.
