First of all, look at her behavior...is she content and happy? Sometimes a short nap is all they need. It sort of messes up the day, but that's par for the course pretty much.
PU/PD and pat/shh are only used when a baby is crying out for you. If she's content playing in her crib, as hard as it is, you might just want to let her be, assuming she's a self-soother and can put herself to sleep if she needs to.
