Which of the following contains a radiopaque strand and is used as a sponge stick for routine surgical cases?

The correct choice is Raytecs because they are specifically designed surgical sponges that contain a radiopaque marker, which makes them visible on X-ray and helps prevent retention in the surgical site. The presence of the radiopaque strand is crucial for ensuring that all sponges are accounted for before closing the wound, thereby reducing the risk of complications such as sponges being left inside the patient.

Raytecs are generally thinner and are ideal for use in smaller surgical areas or for handling finer tissues. They are versatile and often used in various procedures, making them a routine choice in many surgical settings. In contrast, lap sponges, Kittners, and Adson sponges have different functions or structures that do not typically include a radiopaque marker. While these other sponges serve their specific purposes — such as larger areas, dissection, or grasping tissues — they do not meet the criteria of being routine sponges with radiopaque features.
