A nurse is caring for a client who has a new diagnosis of whooping cough. Based on the epidemiological triangle, which of the following is considered the environment for this situation?

Human population distribution

Pertussis virus

Immunization status

Decreased disease resistance

Answer and Explanation

The Correct Answer is A

Choice A reason: In the epidemiological triangle, the environment refers to external factors that cause or allow disease transmission. Human population distribution affects how diseases like whooping cough spread, as high- density areas can facilitate faster transmission.

Choice B reason: The Pertussis virus is the agent in the epidemiological triangle, not the environment.

Choice C reason: Immunization status is a factor that can influence the course of the disease but is not considered the environment in the epidemiological triangle.

Choice D reason: Decreased disease resistance may be a characteristic of the host, which is another corner of the epidemiological triangle, not the environment.

Explanation

Choice A reason: Euphoria is a common effect of heroin use due to its action on the brain's reward system.

Choice B reason: Nystagmus, or rapid involuntary movements of the eyes, is not typically associated with heroin use.

Choice C reason: Tachypnea, or rapid breathing, is not a common finding after heroin use; respiratory depression is more likely.

A. A mentoring program for new staff members B. A zero-tolerance policy by the employer C. Regular social activities for employees D. Training sessions about assertive communication

Correct Answer is B

Explanation

Choice A reason: While mentoring can be supportive, it does not directly address the prevention of workplace violence.

Choice B reason: A zero-tolerance policy sets a clear standard and expectation that violence will not be tolerated, which is essential for prevention.

Choice C reason: Social activities may improve morale but do not directly prevent workplace violence.

Choice D reason: Assertive communication training can help in managing conflict but may not be sufficient to prevent violence.
