The patient is admitted with acute pancreatitis and is demonstrating severe abdominal pain, vomiting, and ascites. Using the Ranson classification criteria, the nurse determines that this patient:
a. has a 99% chance of survival.
b. has a 15% chance of dying.
c. has a 40% chance of dying.
d. has no chance of survival.
B
Patients with acute pancreatitis can develop mild or fulminant disease. As a consequence, research has addressed criteria for predicting the prognosis of patients with acute pancreatitis. The early classification criteria were developed by Ranson, who suggested that the number of signs present within the first 48 hours of admission directly relates to the patient's chance of significant morbidity and mortality. In Ranson's research, patients with fewer than three signs had a 1% mortality rate, those with three or four signs had a 15% mortality rate, those with five or six signs had a 40% mortality rate, and those with seven or more signs had a 100% mortality rate.
