Final answer:
A person on an IV can indeed be sensitive to microshock because the IV bypasses the skin's resistance, substantially lowering the body's threshold for electrical shock.
Step-by-step explanation:
Yes, a person on an intravenous infusion (IV) can be microshock sensitive. This is because the skin's resistance is bypassed by the IV, leading to a lower threshold for electrical shock.
Given that the body's interior has a much lower resistance than dry skin due to the presence of ionic solutions and fluids, an IV can further reduce this resistance. Therefore, currents significantly smaller than the usual shock threshold can produce similar harmful effects in a person with an IV.
