Question 23

To determine the meaning of "trache/os/tom/y", we analyze the word parts: "trache" relates to the trachea (throat), "os" can relate to opening, and "tomy" means incision or creation of an opening. The option "creation of an artificial mouth - like opening in the throat and neck" matches this breakdown. The first option refers to a scope (for examination), the second to lung expansion, and the last to a neck incision without the opening context.

"Pleuro - " refers to the pleura (related to the side of the chest/rib area) and "Costo - " refers to ribs. The option "Rib, Side" aligns with the meanings of these prefixes. "Chest" is too broad, "Rough or Windpipe" is incorrect, and "Lung" is not the meaning of these prefixes.

Answer:

creation of an artificial mouth - like opening in the throat and neck
