A client with peritonitis develops an elevated white blood cell count. The nurse recognizes this laboratory finding as indicative of:

Choice A reason:

Rebound tenderness refers to increased pain upon release of pressure during palpation and is not related to the finding of a rigid, board-like abdomen.

Choice B reason:

Paralytic ileus refers to a condition in which the intestines stop functioning, causing a lack of bowel sounds and distension, but it is not directly related to the rigid abdomen finding.

Choice C reason:

Abdominal compartment syndrome may cause abdominal distension and increased intra-abdominal pressure, but it does not necessarily result in a rigid, board-like abdomen.

Choice D reason:

The finding of a rigid, board-like abdomen upon palpation is known as guarding, which is a protective response of the abdominal muscles in peritonitis to minimize movement and protect the inflamed peritoneum.

Choice A reason:

Abdominal distension and decreased bowel sounds are classic signs of paralytic ileus, a common complication of peritonitis.

Choice B reason:

Gastroenteritis is inflammation of the gastrointestinal tract and may cause diarrhea and abdominal pain but is not related to the specific symptoms described.

Choice C reason:

Appendicitis is inflammation of the appendix and is not related to abdominal distension and decreased bowel sounds.

Choice D reason:

Constipation may cause abdominal distension, but decreased bowel sounds are not characteristic of constipation.
