Why should a puncture device with a broken seal not be used?

It is no longer sterile
The color coding will not match the size
The needle may contain a barb
There may be a manufacturing defect

The correct answer is: It is no longer sterile

A puncture device with a broken seal should not be used because it is no longer sterile. Sterility is crucial in phlebotomy to prevent infections and ensure patient safety. A broken seal indicates that the device has been compromised and could be exposed to contaminants, which poses a risk of introducing pathogens into the patient's bloodstream during the procedure. Maintaining sterility is a fundamental aspect of phlebotomy practices, as it directly impacts the health outcomes for patients. Using instruments that have broken seals could lead to infections or other complications post-procedure, making it essential to always utilize devices that are sealed and sterile.
