A nurse caring for a client who has an infected wound removes a dressing saturated with blood and purulent drainage. How should the nurse dispose of the dressing material?

The correct answer is D: Dispose of the dressing in a biohazardous waste container. This is the appropriate method of disposal for contaminated materials like blood and purulent drainage. Biohazardous waste containers are specifically designed to safely contain and dispose of potentially infectious materials. Double-bagging the dressing (option B) is a good practice for some situations but may not be sufficient for highly contaminated materials. Enclosing the dressing in a single clear plastic bag (option A) or discarding it in the bedside trash receptacle (options A and C) does not provide adequate containment for potentially infectious materials and could pose a risk of exposure to healthcare workers and others.
