Final answer:
Saline-soaked gauze does not prevent edema in a medical emergency situation such as evisceration.
Step-by-step explanation:
The statement is True. Saline-soaked gauze does not prevent edema. Edema is the swelling caused by the accumulation of excess fluid in the body's tissues. While the immediate application of sterile gauze soaked in sterile saline over the extruding tissues helps to prevent bacterial invasion, infection, and drying of the tissues, it does not have a direct effect on preventing edema.
