The Torn Glove, the Liquid Bandage, and One Spare Pair
On a Wednesday afternoon, a dental hygienist is 40 minutes into full-mouth periodontal debridement on a 55-year-old patient whose chart lists treated hepatitis C and type 2 diabetes. While repositioning the suction, she notices a 1 cm tear across the palmar surface of her right index glove, and a smear of the patient's blood sits against the skin underneath. Three days ago she nicked that same finger with a paper clip, and the spot is covered with a liquid bandage. She also wears a gel nail extension on the right thumb and a ring with a raised setting on her left hand. Glove supply in the room is down to one pair. Three more patients are booked this afternoon, and the front desk says the schedule is already running 20 minutes behind.
1. Walk through her actions from the moment she sees the tear to the end of the appointment. Is this an exposure incident?

Stop and secure the site. She should stop instrumentation, remove both gloves (not just the torn one), and perform hand hygiene with soap and water - not hand rub - because the skin is visibly contaminated with blood. Wash for at least 20 seconds, dry with disposable towels, then inspect the finger under good light.
Exposure determination. An exposure incident is contact of blood or other potentially infectious material with non-intact skin, mucous membranes, or through a percutaneous injury. A three-day-old cut is non-intact skin, and a liquid bandage is a film, not a verified intact barrier. If inspection shows blood reached the break, this is an exposure incident: report it to the employer immediately and let the evaluating healthcare professional decide about source testing and post-exposure follow-up. She should not make that determination herself, and she should not wait until the end of the day.
Resume safely. Cover the site with a fresh waterproof dressing if needed, don new gloves, and continue only if bleeding is controlled and she can work effectively. The single spare pair is not a reason to keep working in a torn glove: she must restock before the next patient, and if she cannot, the appointment waits.
Document the event per the office exposure control plan.
2. The assistant suggests she just rub alcohol-based hand rub on her hands under new gloves, 'since the blood is on the outside.' Evaluate that advice.

The advice fails on two counts.
Wrong agent for the condition of the hands. Alcohol-based hand rub is indicated for routine decontamination when hands are not visibly soiled. Blood is visible organic material; alcohol is rapidly inactivated by proteinaceous material and does not remove soil. Soap and water is required whenever hands are visibly contaminated with blood or body fluids.
Wrong sequence. Hand hygiene is performed before donning gloves and after doffing them. Hand rub applied under gloves is not a substitute for either, and alcohol left against skin under an occlusive glove is irritating and degrades the glove material.
The correct reasoning is not 'the blood is outside, so it does not count.' The tear means the barrier failed; whatever was on the outside of the glove reached the skin. That converts the moment into a hand hygiene event plus an exposure evaluation, not a quick re-glove.
3. What do standard practice and most office policies require regarding her nail extension and ring, and why does it matter here?
Read the worked answer
Nails. CDC guidance advises against artificial nails and extenders for staff providing direct patient care to high-risk patients, and many state boards and office policies extend that to all patient care. Artificial and extended nails carry higher microbial loads, are harder to clean under and around, and are associated with lower hand hygiene adherence and more glove tears. Natural nail tips should be kept short (under about one quarter inch), and polish should be intact. Her gel extension should come off before she returns to patient care.
Jewellery. Rings with raised settings and stones create crevices that retain organisms and interfere with effective hand washing and glove fit; the standard is to remove all hand jewellery before hand hygiene and patient care, not to wash around it.
Why it matters here: she has just had a barrier failure over a break in the skin on a patient with a bloodborne pathogen. Every factor that reduces the effectiveness of hand hygiene or increases the chance of another tear raises her risk for the rest of the afternoon. The correct response is to fix the nails and remove the ring now, not at the end of the shift, and to note it in the exposure documentation.
