Final answer:
The nonadherent, nonpermeable, occlusive surgical dressing among the listed options is Tegaderm. It offers a sterile barrier that is transparent and does not allow air or fluids to pass through, suitable for wound management.
Step-by-step explanation:
The correct answer to which of the following is a nonadherent, nonpermeable, occlusive surgical dressing is D. Tegaderm. Tegaderm is a brand of transparent dressing known for creating an occlusive environment, which means that it does not allow air or fluids to pass through. It's designed to be placed over wounds and provide a sterile barrier, protecting the site from infection and allowing for visual monitoring without removing the dressing. In contrast, Telfa is known to be nonadherent but it is not occlusive. Tegasorb, while highly absorptive and semi-occlusive, is also not completely nonpermeable. Xeroform is a petrolatum-based dressing that may be occlusive but also adheres to some extent due to its composition.
