causes swelling of tissue resulting to inflammation of appendix S/S: abdominal pain, fever, and increase swelling of appendix. Vomiting and loss of appetite

Pain- located @ RLQ, causing Guarding, Vomiting & loss of appetite

inflammation and infection spread
through the wall of the appendix
causing death of tissue.
The appendix ruptures due

Appendectomy, pain medications

Appendectomy with explore laparotomy
Pain and Antibiotic medications

Perforation (formation of a hole in an organ), fecal materials exits to peritoneal cavity causing formation of abscesses (periappendiceal abscess). Infection can spread throughout the abdomen (peritoneal cavity)
