Need help writing an objective on my resume can you help me?

hello,

wondering if you can help me write my objective on my resume...
i am looking to become a nurse and to get back into the medical field.
i have direct patient care as an ma in the past. what can i say to stress my objective?
any ideas? thanks so much!
It should be short and sweet. They won't be looking for why you became a nurse, but why you are applying for that job. For instance...To work as a Registered Nurse in a critical care setting that will allow me to learn and continue to develop my clinical skills.
