A nurse is assessing an outbreak of mumps among school-age children. Using the epidemiological triangle, the nurse should recognize that which of the following is the host?
The school
The vaccine
The virus
The children
The Correct Answer is D
The correct answer is choice D, the children. The epidemiological triangle is a model that helps in identifying and analyzing the causative factors of disease outbreaks. It consists of three elements: host, agent, and environment. In this case, the children are the host, as they are the ones who have contracted the disease. The virus (choice C) is the agent, as it is the causative factor of the disease. The school (choice A) and vaccine (choice B) are not the host or agent, but rather part of the environment. The school may be a setting where the outbreak occurred, while the vaccine is a preventive measure but is not directly involved in causing or treating the disease. Therefore, the correct answer is choice D, the children.

Correct Answer is C
Explanation
The correct answer is Choice C because, "Evaluate the client's home environment." Since the client has a new prosthesis, the priority is to evaluate the client's home environment for safety and accessibility.

Determining eligibility for a skilled nursing facility (Choice B is wrong because) and asking about insurance coverage for home health services (Choice D is wrong because) are important considerations, but not the priority assessment in this situation.
