There is a right job for everyone in the world and before planning a new career or if you just want a new job then you need to strongly consider if you can handle a job in healthcare because it can sometimes be gruesome work but so can the schedule of shifts.
Once you are aware that you are experienced enough to apply then I would suggest filling in the application form and posting it as soon as possible. There is no harm in doing so and if you later change your mind or find alternative employment, this will not have any bad bearings on you, they would rather be told the truth.
You never know what jobs are going to appear in the future so if necessary get training where you can in your chosen field and this will strengthen any application submitted for possible employment. Whilst experience is not always necessary if you can present evidence of gained knowledge then this shows you are willing to learn and dedicate yourself to colleagues and patients.
It is guaranteed competition will be fierce but do the best you can and most importantly if you do secure an interview, well done but remember to be yourself. Fake sincerity will show through.
