Hi Pam, My daughter is just starting nursing. It is a Great career. The most important is keeping your grades up. Getting into nursing school is the hard part. Stay determined and don't give up. In the end it will all be worth it.
In practice it can also be difficult: dealing with patients at a very vulnerable time, dealing with difficult family members, keeeping up to date on latest developments inf procedures ormedications.
Finally it can also be physically demanding. Increasingly obese patients need more help transferring to and from hospital beds.
No matter what career you choose its going to take hard work and dedication. Stay focused, determined and committed to keeping up your grades. In order to become a registered nurse you will need to get into a nursing program at a university or college, take and pass an exam and obtain a state license. I have provided the link below so that you can take a look at some of the requirements and courses you will need. I hope this information helps good luck.
