An 8-Year-Old Boy Was Admitted to the Hospital with a Temperature

An 8-year-old boy was admitted to the hospital with a temperature of $101^{\circ} \mathrm{F}$ , a furred tongue, and pain in the right lower quadrant. On examination, the skin on the right lower quadrant was tender to the touch, and the abdominal muscles were contracted and rigid. A diagnosis of acute appendicitis was made.
-The symptoms and signs displayed by this patient can be explained by the following statements except which?

A) An acutely inflamed appendix produces an inflammation of the peritoneal coat covering it.
B) Should the inflammatory process spread, for example, if the appendix should rupture, the parietal peritoneum would become involved.
C) The parietal peritoneum, the abdominal muscles, and the overlying skin are supplied by the same segmental spinal nerves.
D) The segmental nerves supplying the right lower quadrant of the abdominal wall are T7, T8, and T9.
E) The pain in the right lower quadrant and the regional contraction of the abdominal muscles is an attempt by the body to keep the inflamed appendix immobile so that the inflammatory process remains localized.
