What is the physiological effect of moist heat on the treated area?

Choice A rationale
Sanguineous drainage is indicative of active bleeding and is typically bright red due to the presence of red blood cells. This type of drainage is not yellow-red and is not consistent with the description provided.

Choice B rationale
Serous drainage is clear and watery, and it is the fluid that is seen in blisters. It does not have a yellow-red color, so it does not match the description of the drainage observed.

Choice C rationale
Serosanguineous drainage is a mixture of serous and sanguineous drainage. It is typically light red or pink in color, which corresponds with the moist yellow-red stain described, indicating the presence of both plasma and red blood cells.
Choice D rationale
Purulent drainage is thick and opaque, usually yellow, green, or brown, and is associated with infection. The description of a yellow-red stain does not suggest that the drainage is purulent.

Choice A rationale
Wrapping the dressing in a clear plastic bag and discarding it in the bedside trash receptacle is not appropriate because the dressing is saturated with potentially infectious material.

Choice B rationale
Double bagging and labeling the dressing as “biohazard” is part of the correct procedure, but sending it for decontamination is not typically done for soiled dressings; they should be disposed of properly.

Choice C rationale
Simply discarding the dressing in the bedside trash receptacle does not follow proper infection control protocols for handling potentially infectious materials.

Choice D rationale
Placing the dressing in a biohazardous waste container is the correct method as it ensures safe disposal and prevents the risk of infection transmission.
