Correct Answer is A

Explanation

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.

A. Legislative branch of government B. Constitutional branch of government C. Executive branch of government D. Judicial branch of government

Correct Answer is A

Explanation

A. Legislative branch of government: The legislative branch (e.g., Congress, Senate) is responsible for making laws and passing bills. Lobbying for healthcare funding directly involves the legislative process.

B. Constitutional branch of government: There is no specific constitutional branch of government. The U.S. government consists of the legislative, executive, and judicial branches.

C. Executive branch of government: The executive branch (e.g., the President, state governors) enforces laws but does not make them. The nurse is lobbying lawmakers, not the President.

D. Judicial branch of government: The judicial branch (courts, judges) interprets laws and ensures their constitutionality. It does not pass legislation.
