The public health nurse identifies that childhood obesity is a significant problem at the local elementary school. This is an example of which public health core function?

Tertiary Prevention

Policy Development

Assessment

Assurance

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is A

Explanation

Choice A reason: HPV causes warts with a cauliflower-like, elevated growth due to viral-induced epidermal hyperplasia. Types 6 and 11, for instance, trigger keratinocyte proliferation, forming rough, clustered lesions, a hallmark distinguishing them from other skin infections biologically and clinically in appearance consistently.

Choice B reason: Vesicles ulcerating in 1-4 days describe herpes simplex, not HPV. Herpes viruses cause fluid-filled blisters that burst and crust rapidly due to viral cytopathic effects, differing from HPV’s chronic, proliferative growth pattern without ulceration typically seen in lesions.

Choice C reason: Thin-walled pustules with honey-colored crusts typify impetigo, a bacterial infection from Staphylococcus or Streptococcus. Unlike HPV’s viral, warty growths, these result from pus-filled lesions rupturing, lacking the proliferative, cauliflower-like structure HPV induces in skin tissue distinctly over time.

Choice D reason: Solitary growths with elevated borders and central depression suggest basal cell carcinoma, not HPV. This cancer arises from UV-damaged basal cells, forming a pearly nodule, contrasting HPV’s viral, multi-clustered warts without malignant transformation or central depression typically observed clinically.

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.
