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 B
Explanation
Choice A reason: Demographics is not the priority information for the community health nurse to obtain from each client, as it is not directly related to the transmission or treatment of tuberculosis. Demographics is the statistical data of a population, such as age, gender, race, or income. The nurse may collect this information for surveillance or research purposes, but it is not essential for the immediate care of the client.
Choice B reason: Household members is the priority information for the community health nurse to obtain from each client, as it is crucial for the prevention and control of tuberculosis. Household members are the people who live with or share the same living space with the client. They are at high risk of being exposed to or infected with tuberculosis, as the disease is spread through respiratory droplets from coughing or sneezing. The nurse should identify and screen the household members for tuberculosis, and provide them with prophylactic antibiotics if needed.
Choice C reason: Occupation is not the priority information for the community health nurse to obtain from each client, as it is not directly related to the transmission or treatment of tuberculosis. Occupation is the type of work or profession that the client does. The nurse may collect this information for occupational health or social support purposes, but it is not essential for the immediate care of the client.
Choice D reason: Health history is not the priority information for the community health nurse to obtain from each client, as it is not directly related to the transmission or treatment of tuberculosis. Health history is the record of the client's past and present medical conditions, medications, allergies, or surgeries. The nurse may collect this information for diagnosis or management purposes, but it is not essential for the immediate care of the client.
Correct Answer is B
Explanation
Choice A reason: People who have substance use disorders are not the fastest growing segment of the homeless population, although they are a significant and vulnerable group. Substance use disorders may contribute to or result from homelessness, but they are not the primary cause of the increase in homelessness.
Choice B reason: Families who have children are the fastest growing segment of the homeless population, according to the U.S. Department of Housing and Urban Development (HUD). The number of homeless families with children increased by 9% from 2019 to 2020, and they accounted for 34% of the total homeless population in 2020. The main causes of family homelessness are lack of affordable housing, poverty, unemployment, domestic violence, and health problems.
Choice C reason: Adolescent runaways are not the fastest growing segment of the homeless population, although they are a high-risk and underserved group. Adolescent runaways may face challenges such as abuse, exploitation, mental health issues, and lack of education and employment opportunities. However, the number of homeless youth is difficult to estimate due to their hidden and transient nature.
Choice D reason: Men who are unemployed are not the fastest growing segment of the homeless population, although they are a large and diverse group. Men who are unemployed may face barriers such as low wages, lack of skills, discrimination, and health problems. However, the number of homeless men has decreased by 5% from 2019 to 2020, and they accounted for 60% of the total homeless population in 2020.
