What is the single piece of equipment that makes a patient perceive a doctor nurse as more trustworthy?
This tool that is now synonymous with the practice of medicine is a well designed tool that have helped doctors and nurses listen to the body's internal functions for well over a century.
The design of this instrument is almost intuitively easy to use, or perhaps it's simply been around for so long that everyone grows up knowing how they are meant to use it. If only all medical devices could be this simple and intuitive to use--you know, like our BlackJack cables (sorry, can't help bragging).
