Hot objects have fast-moving energy particles. Cold object's energy particles are slower. If the Nurse places the cold stethoscope (A) on the warm Patient (B), the fast-moving particles of B transfer energy to the slower-moving particles of A resulting in B's jump through the roof. Because B particles now lose some of their kinetic energy to A particles, B particles start to move more slowly. This causes the temperature of B to fall and suddenly plunge back to the bed. Before long, A and B have the same temperature.
It all boils down (no pun intended) to this: Don't touch your patient, who is already in pain, with a cold stethoscope because it can ruin the tiles on the ceiling.
What results have you seen when dealing with a patient's pain and the application of cold objects?
