Step-by-step explanation:
If a sharps container is overflowing when the phlebotomist comes on shift, they should follow proper procedures to ensure safety and prevent the spread of infections.
The phlebotomist should not attempt to force any additional items into an overflowing sharps container, as it can lead to injuries and contamination. Instead, they should notify the appropriate personnel, such as a supervisor or the hospital's infection control department, so that the container can be replaced or emptied in a safe manner.
