my 3 months old scratched me, what should i do?

i have a 3 month old cat, she's never around any other cat, totally on her own in our home. She's starting to scratch people and just 3 hours ago, she scratched me and it bled. It bled but it didn't reach the point of like dripping out her scratch is closely similar to a graze in an unfinished block. Are there any precautions that should be done?
