When mercury is spilled from a dropped thermometer, what should the patient care technician do first?

In the event of a mercury spill, the most critical action is to ensure the safety of everyone in the vicinity, which involves evacuating the room. Mercury is a hazardous substance, and exposure can lead to serious health risks. Evacuating the room minimizes the risk of inhaling toxic mercury vapors or coming into contact with the substance, protecting both the patient care technician and any patients present.

Once the area is clear, the technician can assess the situation and follow proper safety protocol, which typically includes notifying a supervisor who can then manage the spill appropriately and ensure that the correct cleanup procedures are followed. This tiered approach prioritizes safety before addressing the spill itself, thus adhering to best practices in a healthcare setting.
