Final answer:
The first action a phlebotomy technician should take after receiving a needlestick injury is to wash the puncture site with soap and water, followed by reporting the incident and seeking medical evaluation.
Step-by-step explanation:
According to OSHA guidelines, if a phlebotomy technician receives a needlestick injury, the first action that should be taken is to wash the puncture site with soap and water. This is important to minimize the introduction of any potential pathogens into the body and prevent infection. Subsequently, the technician should report the incident to their supervisor and go to a medical facility for further evaluation and treatment as necessary. Immediate washing is a crucial step in the containment and prevention protocol for healthcare workers exposed to potentially infectious materials.
