Hi, Ph.D itself is a program which is pursued after MS. There are integrated programs too.But first you must complete your Masters and then choose your Ph.D area, it has to be decided by you because it's a research-based program and no one else can decide on your behalf.Decide in which area of nursing you want to do your research in, visit University websites for the same. You will understand these a lot better when you do your Masters.

You need to prepare well for the exam so that you can crack this exam and try to focus on your optional subject and general knowledge which is a main focus for this exam.
All the best.
