During a busy night shift in the intensive care unit, a medical intern accidentally sustains a percutaneous needlestick injury to the index finger with a hollow-bore needle while securing an arterial line. The source patient's bloodborne pathogen status is currently unknown.
Arrange the following occupational health and post-exposure management steps in the correct chronological order according to standard infection control protocols.
- 1Immediately wash the puncture site with soap and water.
- 2Report the exposure incident to the occupational health department or designated shift supervisor.
- 3Evaluate the source patient and obtain informed consent for rapid bloodborne pathogen testing.
- 4Initiate multi-drug antiretroviral post-exposure prophylaxis (PEP) for the intern, if indicated.
- 5Schedule baseline and longitudinal follow-up serologic testing for the exposed intern.
Cevap
The correct sequence is: wash the wound, report the incident, test the source patient, initiate PEP if indicated, and finally schedule longitudinal follow-up.
In the event of an occupational percutaneous exposure to bloodborne pathogens, the chronological standard of care focuses first on immediate physical risk reduction, followed by systemic evaluation and appropriate treatment.
1. First aid (washing the site with soap and water) must occur immediately to reduce the viral inoculum at the entry site.
2. Reporting the incident comes next, as the healthcare worker must step away from clinical duties and activate the institutional protocol.
3. Source testing is then coordinated by a neutral provider (not the exposed worker) to assess the actual risk of HIV, HBV, and HCV transmission.
4. Post-exposure prophylaxis (PEP) is initiated based on the source testing results (or empirically if results are delayed and risk is high). PEP is time-sensitive but logically follows the initial risk assessment.
5. Finally, because seroconversion can take weeks to months, a schedule for baseline and longitudinal follow-up testing must be established before the worker concludes their initial occupational health visit.

Adım Adım Çözüm
Anahtar Kavram
The standard protocol for an occupational needlestick exposure prioritizes immediate first aid (washing), followed by institutional reporting, objective risk assessment (source testing by a third party), timely pharmacological intervention (PEP), and longitudinal monitoring.
