Final answer:
A common sign or symptom associated with an epigastric hernia during inspection is a visible bulge or lump in the upper abdominal area.
Step-by-step explanation:
A common sign or symptom associated with an epigastric hernia during inspection is a visible bulge or lump in the upper abdominal area. Epigastric hernias occur when fat or tissue pushes through a weak area in the upper abdominal muscles, resulting in a bulge or lump that can be seen and felt. This bulge or lump is typically located in the epigastric region, which is the area between the belly button and the lower part of the sternum.
