The nurse is at highest risk for blood-borne exposure during which situation?

The important idea is that blood-borne exposure is most likely when a barrier that is contaminated with blood is breached by a sharp. In this scenario, the nurse’s glove is already contaminated with patient blood, and a clean needle sticks through that blood-soiled glove. When the barrier is punctured by a sharp in contact with contaminated material, there's a direct route for blood to reach the nurse’s skin, increasing the chance of transmitting blood-borne pathogens even if the needle itself is clean. The other situations involve sharps or movements that could cause a stick, but without the added factor of breached barrier with contaminated blood. A needle penetrating through a contaminated glove combines both the presence of infectious material and a compromised barrier, making it the highest-risk exposure scenario.
