The Advanced eClinical Training Practice Test

Think about where each organ sits in the abdomen. The right lower quadrant houses the appendix, a small finger-like pouch attached to the cecum of the large intestine. The liver is primarily in the right upper quadrant (though it extends across a bit, it’s not in the lower right). The spleen is located in the left upper quadrant. The left kidney sits on the left side as well. So, among the options, the organ in the right lower quadrant is the appendix. (A helpful clinical note: appendicitis pain often starts around the umbilicus and then localizes to the RLQ near McBurney’s point.)
