Seems like this question has been asked as I remember telling my story before. But I'll add my 2 cents for what they are worth.
Alot of my fellow students were talking about taking a CNA course in the summer before nursing school started. I spoke with a nurse who had been acting as my mentor. Her advice was to take the summer off and spend time with my family and just relax as I was about to start the most stressful time of my life.
One of my friend's started the course but quit so she could spend time with her grandkids.
The first semester of nursing school, we learned about direct patient care stuff . . . making beds, taking vitals, giving baths, etc. So, you will learn it anyway.
I always make it a point to think of what I do as being part of a team . . .I help the CNA's - while they shower a patient, I make the bed. I empty urinals (I hate it when a nurse is in the room and a patient asks for a urinal to be emptied and the nurse LEAVES the room to get the CNA - geez, just empty it!), help a patient up to the bedside commode, etc. Taking a CNA class won't necessarily make you a better nurse . . character and a good work ethic is something you have or you don't.
I think I'm a good nurse and work well with my CNA's without having to take the class.
And I'm grateful for that summer. My poor family suffered once I started school.
Good luck and hang on to your hat . . . you're in for a ride!
