Question

a community health nurse is providing teaching to a group of college students who are preparing for a cultural immersion trip to a country where malaria is endemic. the nurse recommends the students spray a mosquito insecticide in their sleeping quarters before bedtime each night. which of the following parts of the epidemiologic triangle does the nurses recommendation reflect? host environment vector agent

Explanation:

The epidemiologic triangle consists of host, agent, and environment. The environment includes factors that affect the spread of disease, like the setting where exposure occurs. Spraying insecticide in sleeping quarters modifies the environment to reduce mosquito (vector) presence, so this targets the environment component. Host refers to the organism (students) at risk, vector is the mosquito (the carrier), and agent is the pathogen (malaria parasite). The nurse's action is altering the environment.

Answer:

B. Environment
