Which of the following is most likely to cause airborne contamination in an operating room?

Dust particles are indeed the most likely cause of airborne contamination in an operating room. Airborne contamination refers to the presence of infectious agents or particulate matter that can be inhaled or settle on sterile surfaces during surgical procedures. Dust particles can carry bacteria, fungi, and other microorganisms, which can lead to post-operative infections if they contaminate the surgical site.

In an operating room, a sterile environment is crucial for patient safety. Dust can be generated from various sources, such as unclean equipment, foot traffic, or the use of non-sterile materials. Adequate cleaning protocols and the use of appropriate air filtration systems are essential to reduce dust accumulation and maintain a sterile environment.

Understanding airborne contamination is key in intraoperative monitoring, as it emphasizes the importance of maintaining sterile conditions to prevent surgical site infections and other complications during procedures.
