While cutting my nails I accidently cut off a chunk of skin and it is now bleeding, but I already asked my mom to put a dressing on it to make the bleeding stop. この表現は自然ですか？

@Eduardoakaedu I've never heard it used nowadays, it's a pretty old idiom. "Put a bandage on" is used now. (Though bandaids (a brand) are very popular and many people don't know the difference, so "Put a bandaid on" is even more casual.)
