1. A simulation system for teaching patient care, the system comprising: a simulator having a body sized and shaped to simulate at least a portion of a natural human body; at least one sensor secured to the body of the simulator, the at least one sensor including a radiofrequency identification (RFID) tag and a coil operably connected to the RFID tag such that the at least one sensor emits a signal comprising a unique train of frequencies when interrogated; and a virtual instrument for use with the simulator in performing a simulated patient care activity, the virtual instrument configured to interact with the at least one sensor coupled to the body in performing the simulated patient care activity, the virtual instrument including an acquisition coil configured to interrogate the at least one sensor to cause the at least one sensor to emit the signal comprising the unique train of frequencies.
