I'm starting a CNA class at a hospital next month (yay!), and I'm wondering if I need to/should buy a stethoscope before the class starts. I realize if I was required to, they would have told me, but I'm wondering if it would be worth it just so I could practice BP at home on my hubby (haven't told him yet he'll be my guinea pig!). I've heard manual BP is one of the harder skills to learn, and the better the stethoscope, the easier it would be. So, before I drop a bunch of money, I wanted to get some advice from other CNA's, especially on what kind would be good if I do get one. And does the type of cuff matter, or are those all pretty much the same? Thanks for your advice!!
