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 C
Explanation
Choice A rationale
The Local Red Cross chapter is not responsible for reporting cases of Lyme disease to the CDC. The Red Cross is primarily involved in disaster response, blood donation, health and safety training and education, and support to military families.
Choice B rationale
The Hospital infection control department is not responsible for reporting cases of Lyme disease to the CDC. While hospital infection control departments play a crucial role in preventing and controlling infections within healthcare settings, they do not typically report cases of diseases like Lyme disease to national public health agencies.
Choice C rationale
The State health department is responsible for reporting cases of Lyme disease to the CDC. Reports of Lyme disease are routinely collected and verified by state and local health departments in accordance with their legal mandate and surveillance practices. After removal of personal identifiers, selected information on cases is shared with the CDC through the National Notifiable Diseases Surveillance System (NNDSS)4.
Choice D rationale
The Office of the Surgeon General is not responsible for reporting cases of Lyme disease to the CDC. The Office of the Surgeon General provides leadership and coordination of U.S. Public Health Service commissioned corps and communicates the best available scientific information to advance the health of the nation.
Correct Answer is B
Explanation
Choice A rationale
Storing used syringes in a biohazard bag before discarding is not the recommended method for disposal of insulin syringes. Used needles and other sharps are considered medical waste and should be placed in FDA-cleared sharps disposal containers.
Choice B rationale
This is the correct answer. Used syringes should be discarded in a hard, plastic container, such as a detergent bottle or a sharps container. These containers prevent needle-stick injuries during the disposal process.
Choice C rationale
Taking containers of used syringes to the local recycling center is not a safe or recommended method for disposal of insulin syringes. Used needles and other sharps are considered medical waste and should not be recycled.
Choice D rationale
While wearing gloves can provide an extra layer of protection when handling used syringes, it is not a sufficient method for safe disposal. Used syringes should be immediately placed in a hard, plastic container after use.
