Final answer:
A puncture device with a broken seal should not be used because it is no longer sterile. It is important to use sterile instruments to ensure patient safety and prevent the spread of infections. Procedures that involve penetrating sterile tissues require a sterile field maintained by proper aseptic technique.
Step-by-step explanation:
A puncture device with a broken seal should not be used because it is no longer sterile. When the seal is broken, the device can be contaminated with bacteria or other microorganisms, which can increase the risk of infection. It is important to use sterile instruments to ensure patient safety and prevent the spread of infections.
In medical settings, sterile instruments are crucial for procedures that involve penetrating sterile tissues or coming into contact with mucous membranes. These procedures require a sterile field maintained by proper aseptic technique. Maintaining a sterile field involves practices such as wearing gloves, using sterile equipment, and implementing techniques to prevent contamination.
