Choice C reason: Referral is tertiary, managing lead toxicity. Screening fits, per nursing. This errors in level. It’s universally distinct, treatment-based.

Correct Answer is C

Explanation

Choice A reason: Tertiary prevention treats obesity, not identifies it. Assessment spots issues. This errors per public health standards. It’s universally distinct, a later step.

Choice B reason: Policy development follows identification, not the spotting itself. Assessment fits. This misaligns with nursing core functions. It’s universally distinct, not first.

Choice C reason: Assessment identifies health problems like obesity in communities. This aligns with public health standards. It’s universally applied, distinctly the initial function here.

Choice D reason: Assurance ensures services, not problem identification. Assessment precedes it. This errors per nursing standards. It’s universally distinct, a subsequent action.

A. Environment B. Agent and host C. Host D. Agent

Correct Answer is D

Explanation

Choice A reason: Environment is setting; bacteria are the agent causing infection. This errors per epidemiology standards. It’s universally distinct, not causative.

Choice B reason: Agent and host combine; bacteria alone are agent. This misaligns with triangle definitions. It’s universally distinct, overly broad.

Choice C reason: Host is the infected person, not bacteria. Agent fits, per nursing. This errors in role. It’s universally distinct.

Choice D reason: Agent is the bacteria causing vaginal infection, per epidemiology. This aligns with nursing standards. It’s universally applied, distinctly accurate.
