I always have 2 stethoscopes for use. the "expensive" ones might not be "all they're cracked up to be" because I've learned it's not how much money you put into the scope that matters, it's how well you can HEAR or LISTEN that matters. Having said that, I had a "el cheapo" sprauge dual tube scope (20 bucks) that was the worst one I've ever used, but carry 2 ten - dollar single tube ones now , and can hear best with those, even outdoing the littman's I've borrowed. It boils down to a matter of affordability, practice, and knowing your own preferences. In the hospital, there are supposed to be disposable scopes available for the Isolation Carts so in a pinch, I'd rob that if I had to. I started out as a Medic, worked as Patient Care Tech in over 3 hospitals, and can say this. A Nurse may or may NOT have her scope with her, and may only have one, but ask ANY Nurse, and they'll tell you the GOOD nurses are the ones who ALWAYS have a good scope with them. You never know when you're going to need it. My scope is multi purpose. It carries tape, a tourniquet, and is a good scope, and helps to identify me from the professional that I am from the "daily housekeepers." I won't ever be found without a GOOD one, especially as a Student Nurse..
