Dear Prashanthi,
Nursing is one of the noblest professions. It is a profession that need lot of patience, responsibility and dedication. If you are kind at heart and have love and concern for the sick and needy people, they go for it. But with 10th standard, you won't get admission to nursing. You have to complete your +2 with science subject and can write the entrance examination for b.sc. nursing which has more scope. Or can join for general nursing.

All the best
