When intra-op X-ray is needed, what should the surgical technologist do to prevent contamination?

The correct approach is to cover the X-ray cassette with a sterile cover. This is essential because the X-ray cassette can come into contact with the sterile field during surgery. To maintain a sterile environment and prevent contamination, it's crucial that any equipment that may enter or be near the sterile field is properly covered. By using a sterile cover, the surgical technologist ensures that no bacteria or contaminants from the cassette can transfer to the surgical site, preserving the integrity of the sterile field and reducing the risk of post-operative infections.

Using non-sterile covers would not adequately protect against contamination, as they do not meet the requirements for maintaining sterility. Performing X-ray without any covers would directly expose the surgical instruments and site to potential contaminants from the cassette. While having the patient wear a lead apron is important for radiation safety, it does not address the need to maintain the sterility of the surgical field during the X-ray procedure. Therefore, covering the X-ray cassette with a sterile cover is the best practice in this scenario.
