A migrant farmworker presents to the clinic reporting an acute onset dizziness, intense thirst, vomiting, fatigue, and headache with difficulty concentrating. Which of the following conditions would cause such symptoms?

Appendicitis

Bacterial gastroenteritis

Viral illness

Pesticide poisoning

Answer and Explanation

The Correct Answer is D

Choice A reason: Appendicitis causes abdominal pain, not farmworker symptoms broadly. Pesticide fits, per nursing standards. This errors in symptom match. It’s universally distinct.

Choice B reason: Gastroenteritis lacks dizziness, concentration issues; pesticide covers all. This misaligns with occupational health. It’s universally distinct, incomplete symptom fit.

Choice C reason: Viral illness is vague; pesticide explains farmworker exposure symptoms. This errors per nursing specificity. It’s universally distinct, less likely here.

Choice D reason: Pesticide poisoning causes dizziness, thirst, vomiting, fatigue, headache in farmworkers. This aligns with occupational health standards. It’s universally distinct, accurate.

Correct Answer is A

Explanation

Choice A reason: Prevalence measures all cases (new and existing) of a disease in a population at a given time. This formula captures total burden, like diabetes cases, divided by population, adjusted by a base (e.g., 1000), reflecting overall disease presence accurately.

Choice B reason: This formula calculates sensitivity, not prevalence. It’s used in diagnostics to assess true positive rates for diseases like cancer against missed cases, focusing on test accuracy, not the total number of affected individuals in a population over time.

Choice C reason: This represents specificity, evaluating true negatives in diagnostic testing, not prevalence. It’s relevant for ruling out disease, like tuberculosis, but doesn’t quantify how many people currently have it within a population, missing the broader epidemiological scope entirely.

Choice D reason: This defines incidence, not prevalence, counting only new cases over time, like annual flu cases. It excludes existing cases, underrepresenting the total disease load in a population, which prevalence aims to capture comprehensively for health planning.

A. Giving direct care to ill individuals within their family setting B. Providing care to manage acute or chronic conditions C. Providing care to individuals and families D. To preserve, protect, promote, or maintain health and prevent disease

Correct Answer is D

Explanation

Choice A reason: Direct care is narrow; community nursing aims broader prevention. This errors per public health standards. It’s universally distinct, not the overarching goal.

Choice B reason: Managing conditions is part, not the full community goal. Prevention is key. This misaligns with nursing scope. It’s universally distinct, too limited.

Choice C reason: Individual/family care is included, but prevention is the goal. This errors per nursing standards. It’s universally distinct, lacks preventive focus.

Choice D reason: Preserving, promoting health, and preventing disease define community nursing. This aligns with public health standards. It’s universally recognized, distinctly comprehensive in scope.
