Final answer:
The AC area should be avoided for IVs because it is more sensitive to microshocks, which can cause harm when the body's resistance is bypassed. Healthcare professionals choose alternative sites for IV insertion to reduce the risk of microshocks.
Step-by-step explanation:
When administering intravenous (IV) fluids or medications, it is generally recommended to avoid the AC (antecubital) area, which is the bend of the elbow, for IV insertion. This is because the AC area is more sensitive to microshocks, which are small electrical currents that can cause harm to the body.
Most of the body's resistance is in its dry skin. When the skin is wet, its resistance decreases significantly. If the skin resistance is bypassed, such as by an IV infusion, a person becomes microshock sensitive, meaning that even smaller electrical currents can have a greater effect on the body. The AC area, being more exposed and sensitive, increases the risk of microshocks.
For this reason, healthcare professionals typically choose alternative sites for IV insertion, such as the veins in the lower arm or hand, where the risk of microshocks is lower. These areas may still require precautions and sterilization, but they are generally considered safer for IV administration.
