When evaluating a patient with acute pancreatitis, which of the following physical or diagnostic findings is an ominous finding that indicates a seriously illpotentially moribund patient?
Correct Answer: C
Rationale: The Grey Turner sign is characterized by bruising in the flanks and is a rare finding associated with acute pancreatitis. It indicates retroperitoneal bleeding and is considered an ominous finding that suggests a severe and potentially moribund state in patients with acute pancreatitis. The presence of the Grey Turner sign should prompt immediate intervention and close monitoring in a hospital setting. The other options, severe epigastric pain with radiation to the back, abdominal guarding and rigidity, and obturator sign, are indicative of pancreatitis but do not carry the same ominous implication as the Grey Turner sign.
