A client is suspected to have colorectal cancer (CRC). Which complications should the nurse monitor for?

The correct answer highlights bowel perforation as a critical complication to monitor in a client suspected of having colorectal cancer (CRC). This concern arises from the fact that CRC can lead to the obstruction of the bowel and the weakening of the intestinal wall due to tumor growth or invasion. When a tumor grows extensively, it can compromise the structural integrity of the bowel, increasing the risk of perforation. If the bowel perforates, it can result in the leakage of intestinal contents into the abdominal cavity, leading to peritonitis and a life-threatening condition.

In the context of colorectal cancer, this complication is particularly significant because it not only reflects the severity of the disease but also requires immediate medical intervention to prevent further complications and stabilize the patient. Monitoring for signs of bowel perforation, such as abdominal pain, fever, and changes in bowel habits, is essential for timely diagnosis and treatment.

Other possible complications, like sepsis or diarrhea, can occur, but they are less directly tied to the immediate risks associated with CRC itself. Cholecystitis, which is inflammation of the gallbladder, does not have a direct connection to colorectal cancer and is therefore less relevant in this scenario.
