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 A
Explanation
The correct answer is Choice A because, "Low literacy." Low literacy is a client-related barrier to learning because clients with limited reading and writing skills may have difficulty understanding written educational materials.
Choice B is wrong because, "Limited experience," is not the correct answer because it is not a client-related barrier to learning. Choice C is wrong because, "Lack of credibility," is also not the correct answer because it is not a client-related barrier to learning. Choice D is wrong because, "Fear of public speaking," is not the correct answer because it is not a clientrelated barrier to learning but rather a psychosocial barrier to learning.
Correct Answer is A
Explanation
The correct answer is Choice A because "Assess the client's need for wound care supplies." Planning for wound care supplies is essential for a client who has a major burn injury. Wound care is crucial to prevent complications such as infection, and the case manager must ensure that the client has access to the appropriate wound care supplies.
Choice B is wrong because, "Provide physical and occupational therapy for the client in her home," is not the correct answer because physical and occupational therapy are interventions provided by therapists and not case managers. Choice C is wrong because, "Deliver family counseling to members of the client's household," is an example of psychosocial support and is not the primary responsibility of the case manager. Choice D is wrong because, "Administer personal care with bathing, dressing, and meal preparation for the client," is an intervention that is typically provided by home health aides and not case managers.
