Any suggestions on how I could truly prevent a surge danger for under $100 bucks
so that I can safely use the stethoscope and the powered speaker system?

Don't use the wired speakers. You're correct that they may constitute
a shock hazard.

There are various wireless adapters for the iPod.

The iPod transmits the audio to a common FM receiver. The wireless
provides the necessary isolation. Note that the various models are
specific to whichever model iPod you're using. It appears that the
transmitter covers up the microphone hole, so you may need to play
with some adapters. Worst case, you can use the iPod as a recorder
with the microphone attached, and then plug in the FM transmitter when
playing back the recording.
