Yes, they might need their claws clipped as they age. You can do it with a nail clipper or nail scissors. Just nip the tip off. It doesn't take much and is much less traumatizing than taking her to a vet or groomer.
lol In that case, leave it to the pros.
Take her to a vet, they should be able to clip her claws without worries ^.^
Yes, she can pull a nail and that would be painful.
All cats are different. One of my dogs need his nail cut more often.
Do you have a scratch post? Supposed to wear them down themselves if they have somewhere to do it.
Might be too late but couldn't hurt for next time.
