Correct Answer is D
Explanation
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.
Correct Answer is B

Choice A reason:
Inserting a catheter into the bladder to collect urine is not related to diagnostic paracentesis for peritonitis.
