Final answer:
The clinical manifestation of acute pancreatitis being asked about is Turner's sign (bluish discoloration of the flanks). Jaundice is also a common sign of pancreatitis. Various diagnostic tools are used for prompt diagnosis and treatment.
Step-by-step explanation:
A clinical manifestation of acute pancreatitis can be jaundice, which is the yellowing of the skin and whites of the eyes. Other common signs include intense pain in the central abdomen that may radiate to the back, pale stools, and dark urine. The correct answer to the question is: B) Turner's sign (bluish discoloration of the flanks). Although not as common as jaundice, Turner’s sign can occur in acute pancreatitis when hemorrhagic fluid tracks around the flank areas. This is different from the Cullen's sign, which is a light blue discoloration around the umbilicus. It's important to diagnose and treat acute pancreatitis promptly, and diagnostic tools such as abdominal ultrasound, blood tests, and computed tomography (CT) scan with contrast dye can be utilized.
