Final answer:
Patients with terminal disseminated malignancy often face complications like metastasis, DIC, multiple organ failure, and superinfections due to weakened immunity, which can lead to kidney failure and increased mortality.
Step-by-step explanation:
The most common complication for a patient with terminal disseminated malignancy includes a range of severe health issues. Disseminated malignancy implies that cancer cells have metastasized, traveling from the primary tumor through the bloodstream to form new cancers at distant sites. This can lead to multiple organ failure and a variety of symptoms such as fever, hypotension, and disseminated intravascular coagulation (DIC), often causing kidney failure and ultimately, death. In immunocompromised individuals, such as those with malignant conditions, the risk of superinfection also increases due to their weakened immune system, and this can further complicate the clinical picture.
