I think she is being polite since she does view Ranma as an equal in
terms of her blood. 

"Sama" isn't for equals.  It's for superiors.  "Dono" is the respectful, 
but not subservient form of address, used by Washu for Tenchi and 
Cologne for Ranma.  

 Remember according to the blood scan (or something

close to that) in a previous chapters Ranma is part of the Jurai Royal
family. ^_^
