A client with peritonitis is prescribed a nasogastric (NG) tube for decompression. The nurse understands that the primary purpose of the NG tube is to:

Choice A reason:

Chest pain is not a typical symptom of peritonitis, as the condition primarily affects the abdomen.

Choice B reason:

A severe headache is not a characteristic symptom of peritonitis.

Choice C reason:

Abdominal pain and tenderness are hallmark symptoms of peritonitis, resulting from inflammation of the peritoneum lining the abdominal cavity.

Choice D reason:

Shortness of breath is not a common symptom of peritonitis unless there is an associated respiratory complication.

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.
