A community hit by a hurricane has suffered mass destruction and flooding. Sewage facilities are non-functioning, and water is contaminated in the area. The practical nurse (PN) is assisting with the plan of care for clients diagnosed with cholera after an outbreak. Which intervention has the highest priority?

The correct answer is choice D: Provide fluid and electrolyte replacement. Choice A rationale: Isolating all infectious diarrhea victims is not the highest priority in this situation. While it is essential to prevent the spread of cholera, immediate medical intervention to treat those affected takes precedence. Choice B rationale: Administering prophylactic antibiotics as prescribed is not the highest priority because it focuses on prevention rather than treatment. In the case of a cholera outbreak, it is more critical to address the immediate needs of those already diagnosed. Choice C rationale: Administering cholera vaccines may be part of a preventive strategy, but it is not the highest priority during an active cholera outbreak. Vaccination takes time to develop immunity, and the focus should be on treating those already affected. Choice D rationale: Providing fluid and electrolyte replacement is the highest priority in managing cholera. Cholera is characterized by severe diarrhea and dehydration, which can lead to life-threatening complications. Promptly restoring fluids and electrolytes helps prevent shock and organ failure.
