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 children.
The virus.
The Correct Answer is C
The epidemiological triangle is a model that is used to understand infectious disease outbreaks. It consists of three components: the host, the agent, and the environment. The host is the individual or population that is affected by the disease. In this case, the host is the school-age children who have contracted mumps. The agent is the microbe that causes the disease, which in this case is the mumps virus.
The environment includes the physical and social factors that influence the spread of the disease, such as the school setting where the outbreak is occurring.
The vaccine is not the host, but rather a preventive measure that can help reduce the spread of the disease by providing immunity to the virus.

Regular exercise is an essential component of health promotion for older adults. Exercise helps to maintain and improve physical function, mobility, and independence, reduces the risk of falls, and helps to prevent chronic conditions such as diabetes, cardiovascular disease, and osteoporosis. Exercise also has mental health benefits, such as reducing depression and anxiety.
Scheduling annual dental examinations for the clients (A) is important but is not the best health promotion strategy for older adults at an assisted living facility. While dental health is important, exercise is a more comprehensive strategy that addresses multiple aspects of health.
Providing the clients with a low-fat diet (B) is also important for health promotion, but it is not as effective as exercise in promoting physical and mental health.
Immunizing the clients against influenza (D) is important to prevent infection, but it is not a health promotion strategy that addresses overall health and wellbeing.

Hemianopsia is a visual field defect in which there is a loss of vision in half of the visual field of one or both eyes. It is a serious finding that can significantly impact a person's ability to perform daily activities and can indicate a neurological problem. The nurse should report this finding to the provider immediately to ensure prompt evaluation and management.
Conjunctivitis (A) is an inflammation of the conjunctiva and is not typically an urgent finding, although it may require treatment depending on the underlying cause.
Decreased near vision (B) is a common finding in older adults and can often be addressed with corrective lenses or other interventions. While it should be noted and addressed, it is not a priority finding that requires immediate reporting to the provider.
Increased sensitivity to glare (C) is also a common finding in older adults and can be addressed with interventions such as sunglasses or tinted lenses. While it should be noted and addressed, it is not a priority finding that requires immediate reporting to the provider.
