7:40 p.m. Needlestick, an Unresponsive Source, and an Overfilled Sharps Container
At 7:40 p.m., a phlebotomist finishes a draw on a 34-year-old ED patient with altered mental status. A call light startles her and the 21-gauge needle passes through her glove into the pad of her left index finger, drawing blood. The chart documents no infectious history and the patient cannot answer questions. Her hepatitis B vaccination series was completed eight years ago, but no post-vaccination anti-HBs titer is on file. The source patient's EDTA tube sits in the rack with enough volume for testing. The sharps container in the room is filled past the visible fill line and is wall-mounted at chest height. The supervisor left at 5 p.m.; the exposure control plan is in a binder in her office.
1. List your immediate actions in order for the first 30 minutes, and state what you would not do.

- Wash the wound with soap and running water for about 15 seconds. Do not scrub, do not milk or squeeze the site, and do not apply bleach or caustic agents - there is no evidence they help and bleach damages tissue.
- Report immediately to the charge nurse or on-call supervisor and start the exposure report while the details are fresh: device, gauge, hollow-bore, depth, glove status, source patient, time.
- Go for evaluation now, do not finish the shift's draws. Occupational health/ED manages the source evaluation and the exposed worker's baseline serology (HIV, HBV with anti-HBs, HCV per protocol).
- HIV post-exposure prophylaxis decisions should be made within hours, ideally immediately; PEP is most effective started as early as possible and is generally not offered beyond 72 hours.
- Hepatitis B: a completed series without a documented anti-HBs is an unknown status, not a protected status. Draw anti-HBs; if non-responder, HBIG plus a booster dose is the usual course - that decision belongs to the evaluating clinician, but flagging the missing titer is the lab's job.
What I would not do: I would not run HIV or HCV testing on the leftover EDTA tube on my own initiative. Testing of a source patient requires consent or a documented legal exception under state law and an order from a provider; the laboratory executes the order, it does not create it.
2. The patient cannot consent. The tech in the core lab says, 'There's plenty of blood in the rack, just run it.' How do you handle that?

I would stop it, and explain why in operational terms rather than policy language: the barrier is not specimen availability, it is authorization. Source-patient testing after an exposure is governed by state law and institutional policy, which typically require the patient's informed consent or a documented exception (for example, a provider-directed process when the source cannot consent). A result generated without that authorization is not usable for the exposure decision anyway, and it exposes the lab and the individuals involved to legal and regulatory consequences.
The correct path: the treating physician or ED provider orders source testing through the exposure protocol; the lab then performs it on the available specimen or a fresh draw, and reports it through the designated channel to occupational health - not to the exposed worker's personal knowledge, and not to the general chart without following the disclosure rules. If the exposure protocol allows testing of an existing specimen, the lab documents the authorization reference on the order. My role is to make the process fast, not to bypass it - a call to the on-call supervisor and the ED attending typically resolves this within minutes.
3. What do you do about the sharps container, and why does it belong in the exposure report?
Read the worked answer
Replace it now with a container filled no more than about three-quarters full, and get the overfilled one into the waste stream. A container filled past its fill line forces users to push devices in, and that is a recognized mechanism of injury; standard practice is to replace at the 3/4 mark, not when it is full.
Height matters too: chest-height wall mounting on a startled or hurried user puts the opening in a poor sight line and awkward reach, and containers should be placed at a height that lets the user see the opening and reach it without stretching - below eye level and convenient to the point of use.
Why it belongs in the report: the injury had a contributing engineering condition, not just a startled moment. Reporting it under the Bloodborne Pathogens Standard's sharps injury log lets the site fix the condition (mounting height, replacement schedule, room-by-room checklist) rather than retraining one phlebotomist about 'being more careful.' If the log shows this room recurring, the container placement - not the staff - is the corrective action. Document the container condition, the mounting height, and the replacement in the exposure record and notify the safety officer in the morning.
