The Torn Glove, the Scraped Forearm, and the Overfilled Sharps Container
06:40 on a medical floor. You are collecting a lactic acid and two sets of blood cultures from Mr. P, a 71-year-old inpatient in contact precautions for MRSA. He is confused and pulls at his lines. His left antecubital fossa holds the only usable vein. You cleanse the site with chlorhexidine and wait for it to dry, but as you re-palpate, your left glove tears at the thumb and you feel a small wet spot of blood on the skin of your right forearm, which has a healing 2 cm scrape from yesterday. The sharps container mounted outside his door is at its fill line, with a needle hub protruding past the flap. You are already five draws behind.
1. The site is already prepped and your glove is torn. Walk through exactly what you do before you make the puncture.

Stop and reset; do not puncture with a torn glove.
- Withdraw your hand from the field. Remove the torn glove, perform hand hygiene, and don a new pair. Gloves are single-use; a breach ends their usefulness.
- Because the torn thumb re-contacted skin that chlorhexidine had already disinfected, the prep is no longer valid. Re-cleave? No - re-clean the site with a fresh chlorhexidine applicator and let it dry completely (about 30 seconds, until the skin looks dry, not shiny).
- Do not re-palpate afterward. If you must locate the vein again, palpate before prep and mark the spot with the cap of the needle guard resting beside - not on - the site, or palpate with a gloved finger and re-clean once more.
Reasoning: the antiseptic must be the last thing to touch the skin. The temptation is to 'just go' because the vein is found and the patient is agitated, but a contaminated puncture site defeats the entire prep and can seed a bloodstream infection in a patient already colonized with MRSA.
2. Is the blood on your right forearm a reportable exposure? Justify your answer and outline the next steps in order.
Read the worked answer
Yes - it is reportable, because the skin was not intact.
The general rule is that blood on intact skin is not a portal of entry and does not require post-exposure prophylaxis; washing with soap and water and documenting is enough. Here the blood landed on a 2 cm healing scrape. Non-intact skin is a recognized route of transmission, so this is treated as an exposure, not a spill.
Sequence:
- Immediately: wash the area with soap and water. Do not scrub, do not use bleach, do not squeeze the wound.
- Within the hour: report to your supervisor and occupational health, and complete the exposure form while details are fresh (time, source, body fluid, route, glove status).
- Source is a known inpatient, so source testing can be requested per policy. HIV PEP, if indicated, is most effective started within hours and generally not later than 72 hours.
- Baseline testing and follow-up scheduling are part of the same visit.
Contrast this with a splash on unbroken skin - the decision hinges on the skin's integrity, not on how much blood there was.
3. You still need the specimens. What is your plan for sharps disposal, and what is the reasoning?
Read the worked answer
Do not use the overfilled container, and never force a device into it.
- Carry a replacement container to the point of use; most policies require the container to be within arm's reach during the procedure so the device can be activated and dropped immediately, one-handed, without walking.
- The protruding hub is a hazard to everyone on the corridor. Do not attempt to push it in or retrieve it by hand. Seal the full container, tag it as full, and notify the charge nurse or environmental services so it is removed intact.
- Activate the safety device immediately after the draw, before standing up, and never recap.
Reasoning: overfilling is one of the leading causes of sharps injury, and the injury risk is highest in the seconds right after venipuncture, when the device is uncapped and the phlebotomist is distracted by tubes, tourniquet, and cotton. Solving the container problem first is not a delay - it is the control that makes the draw safe.
