What a great question to consider! To answer this, you obviously need to have studied and analysed her character as it is presented in the play and come to your own conclusions about the sort of person she is and how she would introduce herself today. For me, a key scene for you to study in Act I scene 3, which is when we first meet the Nurse, and we are given a key insight into her character. Consider the following quote and what it tells us about her:
Peace, I have done. God mark thee to his grace!
Thou wast the prettiest babe that e'er I nursed.
And I might live to see thee married once,
I have my wish.
Obviously, character is impacted a lot by each director's way of presenting and the series of choices that they need to make, however from a study of the text itself, we can see that perhaps the most important characteristics of the Nurse are that she is very talkative, she loves Juliet a lot and she is very keen to see her charge (Juliet) become romantically attached, perhaps too keen. In this sense we need to remember that she adds great comedy value to the play, but also could be part of the tragedy, because she encourages Juliet in her relationship with Romeo and acts as a go-between for them.
