Also keep in mind the idea of improvisation. I had to dress a wound once where I only had a couple pads of gauze to dress with because the supplied first aid kid was not very well supplied. There was a new package of toilet paper next to the first aid kit, though! The gauze kept it sterile; the toilet paper kept it absorbent and comfortably soft. Taped it all in place and the hospital got to deal with a ghetto dressing.

But it worked!
