A Suture Needle, a Refused Source Test, and a Friday Clock
At 4:40 on a Friday afternoon, a dental assistant is helping the dentist close after a surgical extraction on a 28-year-old whose health history is blank. While the dentist hands her a loaded needle holder, a distraction at the doorway makes her shift her hand, and the suture needle passes through the thenar eminence of her left palm. It bleeds freely. She is wearing exam gloves. She completed a hepatitis B vaccine series in school but has never had a titer drawn and has no documentation with her. When the dentist asks the patient's permission to test his blood, the patient says he 'would rather not' and asks to leave. The practice closes in 20 minutes; the oral surgeon next door is still operating.
1. State the immediate wound care and everything the employer owes her before the weekend. Justify the timing.

Wound care. Wash the wound with soap and water. Do not squeeze or milk the site, and do not apply bleach or other caustic agents - there is no evidence they reduce transmission and they may damage tissue. Flush thoroughly; if a splash had reached eyes or mouth, irrigate with water or saline. Cover the wound, control bleeding, and stop treating patients with that hand until it is secured.
Employer obligations. Report the incident immediately. The employer must make a confidential medical evaluation and post-exposure follow-up available at no cost, by a licensed healthcare professional, at a reasonable time and place, including prophylaxis when indicated. The evaluation cannot be deferred to Monday as a convenience: HIV prophylaxis should begin as soon as possible, ideally within about 2 hours and generally not later than 72 hours, and hepatitis B immune globulin is most effective within 24 hours of exposure.
Source issues. Attempt to obtain the source patient's consent for testing under state law. If he refuses, document the refusal - that documentation is itself required - and manage the exposure as if the source were potentially infectious.
Her status. A completed vaccine series without a documented titer does not prove protection; the evaluating clinician determines whether testing, additional vaccine, or immune globulin is indicated.
2. The office manager asks which records must be created or updated. Is the sharps injury log required here?
Read the worked answer
Sharps injury log - yes. This is a percutaneous injury from a contaminated sharp, so it belongs in the sharps injury log. Required entries are the type and brand of device involved, the department or work area where it occurred, and an explanation of how the incident happened. It is kept confidential and separate from the personnel file, and entries are made promptly (within about 14 days of when the employer learns of the incident).
Medical record. A confidential medical record is established for this employee and retained for the duration of employment plus 30 years.
Written opinion. The employer must obtain from the evaluating healthcare professional - and give the employee a copy of - a written opinion limited to whether hepatitis B vaccination is indicated and whether the employee received it, and whether HIV prophylaxis is indicated and any follow-up recommendations.
Source documentation. The refusal of the source patient to be tested must be recorded.
Training records are separate and retained 3 years; this event may also trigger a review of the exposure control plan if it exposes a gap in technique or equipment.
Recording on the OSHA 300 log depends on whether prophylaxis constitutes medical treatment beyond first aid; if recordable, it is entered as a privacy case with the name withheld.
3. A colleague says the real mistake was not recapping the needle. Assess that explanation and describe what should change in the transfer technique.
Read the worked answer
Recapping is not the issue here - no recapping occurred. The injury happened during a two-person transfer of a loaded needle holder, which is a recognized high-risk moment because the sharp changes hands while the receiver's attention and grip are divided.
The fix is not a lecture about recapping, but a change in the procedure:
- Use a neutral or safe zone (a designated tray or bracket table area) so the sharp is set down and picked up rather than passed hand to hand.
- Announce the transfer and make eye contact before moving the instrument; no simultaneous conversation with someone at the doorway during a sharp transfer.
- Keep the sharp end oriented away from the receiver's hand, and never hold a loaded needle holder pointing toward another person.
- Keep the sharps container within arm's reach, replace it at three quarters full, and never overfill or force a device into it.
A colleague's after-the-fact 'you should have recapped' explanation is also wrong on its own terms: if recapping were necessary, it must be done with a one-handed scoop technique or a recapping device, never with two hands. Blaming technique without examining the transfer design lets the same injury happen again.
