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 D

Choice Bis wrong because is incorrect because researching the species of mosquito responsible for the outbreak is not an activity that the nurse should perform to implement mosquito control strategies.
Choice Ais wrong because is incorrect because reviewing morbidity rates of encephalitis within the last 6 months is not an activity that the nurse should perform to implement mosquito control strategies.
Choice C is wrong because is incorrect because identifying the number of cases resulting in disability from encephalitis is not an activity that the nurse should perform to implement mosquito control strategies.
Correct Answer is C
Explanation
The correct answer is Choice C because, "Review the immunization records of the child's classmates." Koplik spots are a sign of measles, a highly contagious viral illness. Reviewing the immunization records of the child's classmates can help determine if there is an outbreak and assist in preventing further spread of the illness. Checking the child's classmates for parotid gland enlargement (Choice A is wrong because) is not relevant because it is a sign of mumps, a different illness. Asking the caregivers if the child recently used alcohol-based mouthwash (Choice B is wrong because) and instructing the caregivers to increase the child's Vitamin B12 intake (Choice D is wrong because) are not relevant because they do not relate to the presence of Koplik spots.
Choice A is wrong because: Checking the child's classmates for parotid gland enlargement is not relevant because it is a sign of mumps, not measles.
Choice B is wrong because: Asking the caregivers if the child recently used alcohol-based mouthwash is not relevant to the presence of Koplik spots.
Choice D is wrong because: Instructing the caregivers to increase the child's Vitamin B12 intake is not relevant to the presence of Koplik spots.
