Final answer:
A saturated dressing may allow germs to enter the wound, thus it is important to keep dressings dry to prevent wound infections.
Step-by-step explanation:
When a dressing becomes saturated, it is true that germs can enter the wound from the outside. A saturated dressing can lose its ability to effectively act as a barrier to bacteria and other pathogens. It is crucial to keep dressings dry and intact to help prevent wound infections and ensure proper healing. Pathogens can enter the body through breaches in the skin, and an effective barrier is necessary to prevent this from occurring. Furthermore, medical devices that are inserted into the body can become contaminated with biofilms of microorganisms, making strict sterilization and dressing protocols essential in healthcare settings.
