Which descriptor best describes a normal abdominal inspection?

A normal abdominal inspection is characterized by the abdomen appearing symmetric and flat. This indicates that there are no visible abnormalities such as swelling or distension, which can suggest underlying medical issues. A symmetric abdomen means that both sides are equal in shape and size, with no noticeable bulges or asymmetries that might indicate a problem like organ enlargement or fluid accumulation.

Other descriptors present different clinical scenarios. Distension and pain suggest possible conditions such as obstruction or inflammation, which are not indicative of normal findings. An asymmetric and contracted abdomen may point toward muscle tension or an unusual anatomy that could warrant further investigation. A swollen and tense abdomen can indicate acute issues such as severe inflammation, ascites, or other medical emergencies. Hence, the descriptor of a normal abdomen being symmetric and flat correctly reflects the absence of these concerns.
