A 24-year-old medical student accidentally sustains a percutaneous needlestick injury from a hollow-bore needle immediately after drawing blood from a hospitalized patient. The source patient's human immunodeficiency virus (HIV), hepatitis B, and hepatitis C statuses are currently unknown. Arrange the following steps in the most appropriate chronological sequence for the immediate management of this occupational exposure.
- 1Wash the exposed area immediately with soap and water.
- 2Report the incident to the occupational health or infection control department.
- 3Obtain baseline HIV, HBV, and HCV serologies from both the source patient and the student.
- 4Initiate antiretroviral post-exposure prophylaxis (PEP) if indicated by the source's risk profile.
Cevap
The correct sequence is to first wash the wound, then report the incident, followed by obtaining baseline serologies, and finally initiating post-exposure prophylaxis if indicated.
The standard protocol for a needlestick injury prioritizes immediate mechanical decontamination (washing with soap and water). This is followed immediately by reporting the incident to occupational health, which orchestrates the clinical pathway. Occupational health then facilitates rapid baseline serological testing of both the source and the exposed individual. Finally, based on the testing results or the epidemiological risk of the source, targeted post-exposure prophylaxis (PEP) is initiated. This sequence ensures safety, compliance, accurate risk stratification, and timely medical intervention.

Anahtar Kavram
The chronological management of an occupational needlestick exposure involves immediate decontamination, prompt reporting, risk stratification via serological testing, and initiation of targeted post-exposure prophylaxis if indicated.
