A public health nurse is responding to a newly identified cluster of active tuberculosis (TB) cases within a crowded metropolitan homeless shelter. To effectively manage the outbreak and apply principles of disease prevention, arrange the following nursing actions in the most appropriate sequence of priority from first to last.
- 1Isolate the individuals demonstrating active respiratory symptoms in negative-pressure environments.
- 2Notify the local public health department regarding the cluster of communicable disease cases.
- 3Initiate contact tracing and administer interferon-gamma release assays (IGRA) to exposed residents.
- 4Facilitate the administration of prophylactic isoniazid (INH) therapy to residents identified with latent TB infection.
- 5Implement a shelter-wide educational campaign regarding respiratory hygiene and early symptom recognition.
Answer
The correct sequence prioritizes immediate infection control, followed by legal reporting, targeted screening, prophylactic treatment, and finally, broad population-based education.
In an acute outbreak of a highly contagious airborne pathogen, the nurse must prioritize actions based on the severity of the immediate threat. The sequence begins with immediate source control (isolation) to halt transmission. Once the immediate environment is secured, legal mandates dictate reporting the outbreak to public health authorities. Subsequently, the focus shifts to secondary prevention (screening exposed individuals) and targeted intervention (treating latent infections). Finally, broad primary prevention strategies (education) are deployed to mitigate future risks.
