What 3 components make up the epidemiologic triangle?

A.

Agent, Host, Environment.

B.

Agent, Condition, Variable

C.

Agent, Host, Condition

D.

Agent, Host, Disease

Answer and Explanation

The Correct Answer is A

A. Agent, Host, Environment: The epidemiologic triangle consists of:

    • Agent – The cause of disease (e.g., bacteria, viruses, toxins).

    • Host – The person or animal affected by the disease.

    • Environment – External factors that influence disease transmission (e.g., climate, sanitation, population density).

B. Agent, Condition, Variable: "Condition" and "Variable" are not standard components of the epidemiologic triangle. The correct term is host (the affected person or animal).

C. Agent, Host, Condition: "Condition" is not part of the triangle. The environment is a crucial factor that influences the spread of disease.

D. Agent, Host, Disease: "Disease" is an outcome rather than a component of the epidemiologic triangle. The triangle focuses on the factors that contribute to disease spread, including the environment.

Correct Answer is A

Explanation

A. Veracity: Veracity refers to truthfulness and honesty. The nurse is ethically obligated to report medication errors, regardless of whether harm occurred. Failing to complete an incident report violates this principle.

B. Autonomy: Autonomy refers to respecting a client's right to make informed decisions. This situation involves an error in practice, not a violation of client autonomy.

C. Beneficence: Beneficence refers to promoting the well-being of clients. While not reporting the error may seem like an attempt to avoid unnecessary distress, it is more directly a violation of veracity.

D. Confidentiality: Confidentiality involves protecting a client’s private health information. The failure to report a medication error does not violate confidentiality but does compromise transparency and accountability.


Correct Answer is D

Explanation

A. Answering parents' questions about the safety and importance of vaccines today: While educating parents is essential, it relies on voluntary compliance and does not have the same large-scale impact as mandatory immunization laws.

B. Offering all immunizations to all children for a small fee: Improving vaccine access is important but does not guarantee that parents will vaccinate their children.

C. Educational campaigns to all health care providers about the importance of immunizations whenever a child is seen: While provider education is valuable, it does not enforce vaccinations on a broad population level like school-entry laws do.

D. "No shots, no school" legislation, which legally requires children be immunized before school: School immunization mandates have played a significant role in increasing vaccination rates and reducing outbreaks of preventable diseases such as measles, mumps, and pertussis. These laws ensure high vaccine compliance before children enter school, making them one of the most effective public health measures.
