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 vaccine.
The virus.
The school.
The children.
The Correct Answer is D
Choice A reason: The vaccine is not the host, as it is not a living organism that can be infected by the virus. The vaccine is a preventive measure that can reduce the risk of contracting mumps by stimulating the immune system to produce antibodies against the virus.
Choice B reason: The virus is not the host, as it is the agent that causes the disease. The virus is a microscopic particle that can only replicate inside the cells of a living host.
Choice C reason: The school is not the host, as it is the environment that facilitates the transmission of the virus. The school is a place where many children gather and interact, which increases the exposure and contact with the virus.
Choice D reason: The children are the host, as they are the living organisms that can be infected by the virus. The children are susceptible to the virus because they may not have been vaccinated or have not developed immunity from previous exposure. The children can also spread the virus to others through respiratory droplets or saliva.

Correct Answer is A
Explanation
Choice A reason: Collecting data to identify barriers to learning is the first action that the nurse should take. This is based on the principle of assessment, which states that the nurse should gather information about the needs, interests, and characteristics of the target population before planning any intervention. The nurse should assess the barriers that may prevent the adolescents from participating in or benefiting from the program, such as lack of knowledge, motivation, access, or support.
Choice B reason: Establishing methods to evaluate program outcomes is not the first action that the nurse should take. This is based on the principle of evaluation, which states that the nurse should measure the effectiveness and impact of the intervention after implementing it. The nurse should determine the criteria and indicators that will be used to evaluate the program outcomes, such as changes in knowledge, attitudes, behaviors, or health status.
Choice C reason: Obtaining visual aids that feature adolescents is not the first action that the nurse should take. This is based on the principle of implementation, which states that the nurse should deliver the intervention using appropriate strategies and resources. The nurse should obtain visual aids that are relevant, accurate, and appealing to the adolescents, and that can enhance the learning process and the message delivery.
Choice D reason: Providing computer-based education is not the first action that the nurse should take. This is based on the principle of implementation, which states that the nurse should deliver the intervention using appropriate strategies and resources. The nurse should provide computer-based education if it is feasible, accessible, and preferred by the adolescents, and if it can facilitate the learning objectives and outcomes.
Correct Answer is D
Explanation
Choice A reason: Determining potential funding sources for the program is an important action, but not the first one. The nurse should first assess the needs of the target population, such as the number of older adults who need the service, their nutritional status, their preferences, and their barriers to access food.
Choice B reason: Inquiring about the availability of volunteers is an important action, but not the first one. The nurse should first assess the needs of the target population, and then plan the resources and personnel needed to implement the program.
Choice C reason: Identifying alternative solutions to address concerns is an important action, but not the first one. The nurse should first assess the needs of the target population, and then identify the possible challenges and solutions to deliver the service effectively and efficiently.
Choice D reason: Performing a needs assessment is the first action that the nurse should take, as it provides the basis for planning, implementing, and evaluating the program. A needs assessment involves collecting and analyzing data about the health status, needs, and resources of the target population and the community. It helps to identify the gaps, priorities, and goals of the program.
