Yes, Caroline compelled the nurse wihout knowing it. (S2ep2 if I'm not mistaken)

Scarlett22 - I always thought she knew what she was doing, she just didn't k ow what it was called.

Contributor - I think the sire bond and compulsion are two different things with the same outcome. Not quite the same but with the same result.

No, she's freaking out and says something (my memory doesn't serve me right atm) to the nurse and the nurse obeys. I should be watching that episode tomorrow.
