Final answer:
The doctor may order tests, such as CT scans and blood work, to diagnose acute abdomen complications and determine the appropriate treatment.
Step-by-step explanation:
For acute abdomen complications, the doctor may order various tests and treatments depending on the underlying cause. In the case of peritonitis, which is inflammation of the peritoneum, emergency surgery and intensive antibiotic therapy are usually required. Appendicitis can be ruled out using a CT scan, and if present, surgery may be needed. Diverticulitis can also be diagnosed with a CT scan, and the treatment may range from oral antibiotics and liquid diet for mild cases to intravenous antibiotics and hospitalization for severe cases.
