In Romeo and Juliet, the word that could be used to describe the Nurse is: fickle.

While the Nurse is caring of Juliet, she acts fickle towards the end of the play by switching her position and urging Juliet to marry Paris even though she is married to Romeo ("I think you are happy in this second match,/ For it excels your first...").
