Good morning, my name is Martha. I work as an acute care dialysis nurse and plan to take the CDN exam in March. I'm looking for anyone who has taken the CDN exam and would be willing to give me some pointers/ideas on the test. As the date gets closer the more my anxiety increases. I'm in my tenth year of dialysis and at this time feel like I know nothing. If anyone can help I would certainly appreciate it. Have a great day.
