What 3 components make up the epidemiologic triangle?
Agent, Host, Environment.
Agent, Condition, Variable
Agent, Host, Condition
Agent, Host, Disease
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 B
Explanation
A. Hepatitis B: Hepatitis B is a bloodborne disease, primarily spread through contact with infected bodily fluids, not through a vector.
