A great way to start any problem essay is to give a story about someone experiencing the problem. It can be a personal experience or a typical situation. In the case of the nursing shortage, you can either use the experience of a typical nurse who has too many patients to care for and is feeling stressed or doesn't have the time to do a good job, or it can be a patient who has to wait too long, or has the nurse miss some important health information because they don't have the time to spend with them. Perhaps the patient is thirsty or has to go to the bathroom and has too wait too long for help and soils themselves. After you tell a dramatic story illustrating the problem, it is also most effective if you give some statistics showing the extent of the problem. Use your statistics or statements from an authority to convince the reader that your story is not just an isolated incident, but is actually a common situation that needs correcting.
