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.

Correct Answer is D
Explanation
Bending at the waist to lift heavy objects can increase the risk of back injury, even when wearing a back brace. The nurse should advise this worker to bend at the knees and keep the back straight when lifting heavy objects. The worker who is standing with a wide base of support when pulling a cart toward himself is using proper body mechanics, which helps reduce the risk of injury.
The worker who is 7-weeks postoperative following rotator cuff surgery and is labeling boxes should avoid lifting heavy objects or performing tasks that require excessive use of the affected arm. The worker who is standing in place for extended periods and rests one foot on a box may experience fatigue or discomfort, but is not necessarily at an increased risk for injury.
Correct Answer is A
Explanation
According to the Centers for Disease Control and Prevention, motor vehicle crashes are the leading cause of death among adolescents aged 15-19 in the United States. Therefore, it is crucial for the school nurse to prioritize motor vehicle safety education, including the dangers of distracted driving, seatbelt and helmet use, and avoiding impaired driving.
Substance abuse prevention is also important, but it is not the leading cause of death for this age group.
Sports injury prevention and gun safety are also important topics, but they are not the leading cause of death for adolescents.
