After removing a client's dressing that is saturated with sanguineous drainage, where should the nurse place the dressing?

A. Place in a red biohazard container: Dressings saturated with sanguineous (bloody) drainage are considered regulated medical waste. They must be disposed of in a properly labeled red biohazard container to prevent contamination and comply with infection control standards. B. Place in a regular trash container with a red liner: While a red liner may indicate medical waste, without a biohazard label and designated container, it does not meet safe disposal protocols for blood-contaminated materials. C. Discard into a sink: Disposing of contaminated dressings in a sink is unsafe, violates standard precautions, and poses a serious infection control hazard due to potential contamination of plumbing and surfaces.
