A patient shot in the abdomen has an entry wound in the right upper quadrant and an exit wound in the lower right back. Which organs may have been injured?

The correct answer is B because the bullet's trajectory through the abdomen, entering at the right upper quadrant and exiting at the lower right back, suggests that it could have traveled through several key organs located in that area of the body.

The right upper quadrant contains the liver, gallbladder, right kidney, and portions of the small intestine and pancreas. Given the entry and exit points described, it's possible for the bullet to have damaged the liver, which is a large organ situated in the upper right abdomen. The gallbladder lies just beneath the liver and could also be affected. Similarly, the right kidney is positioned toward the back in the right flank area, making it susceptible to injury from a trajectory that exits in the lower right back area.

In contrast, the other options include organs that do not align with the entry and exit points provided. For instance, option A includes the appendix and spleen, neither of which aligns with the path indicated, as the spleen is located in the left upper quadrant. Option C lists the stomach and diaphragm, which are also not consistent with the injury path through the right upper quadrant to the lower right back. Lastly, option D references the right lung and colon, where the right lung is too far up
