Caring for wounds is a critical task that often requires the expert hands of a licensed nurse to ensure that treatments are performed safely and effectively. This is particularly important when dealing with various types of wounds – from common ulcers and burns to more complex conditions such as pressure sores, surgical incisions, fistulas, tube insertion points, and the raw areas caused by tumors. 

Wounds can differ greatly – in their size, how deep they are, the type of discharge they produce (which could vary in color, smell, texture, and amount), and even the state of the skin surrounding the wound. These characteristics must be carefully documented and assessed by a nurse, as they are crucial to understanding the extent of the wound and the specific nursing care it requires.
