HESI Registered Nurse EXIT Practice Exam

Which lab report is most urgent for the nurse to report to public health?

1. An infant with a positive culture of stool for Shigella

2. An elderly factory worker with a lab report that is positive for acid-fast bacillus smear

3. A young adult commercial pilot with a positive result for Pneumocystis carinii

4. A nurse with varicella-zoster virus and active vesicles

The correct answer is: An elderly factory worker with a lab report that is positive for acid-fast bacillus smear

The most urgent lab report for the nurse to report to public health is the positive result for acid-fast bacillus smear in the elderly factory worker. This finding is critical because it indicates the potential presence of tuberculosis (TB), a communicable disease that poses a significant public health risk due to its ability to spread through airborne particles. In the context of control and prevention efforts, immediate notification to public health authorities is essential to initiate contact tracing, community education, and appropriate isolation protocols to protect the broader population. The urgency stems from the need to manage contagious infectious diseases effectively, especially in settings like factories where individuals may be in close contact with each other. Rapid reporting enables timely intervention strategies to prevent outbreaks, especially considering that TB is a preventable and treatable disease. In comparison, while the other conditions presented also have public health implications, they may not require the same level of immediate action. For example, Shigella, although important, is often managed with containment within the affected community and doesn't have the same level of widespread risk as TB. Pneumocystis carinii typically affects immunocompromised individuals and doesn't generally invoke immediate public health reporting unless it is part of a larger outbreak. Varicella zoster, while contagious, is managed
