A nurse is reviewing the diagnostic results for a client with suspected cholecystitis. Which of the following laboratory findings is commonly elevated in this condition?

Choice A reason:

Dark urine and pale-colored stools are not typically associated with a gastrointestinal infection. These symptoms are more indicative of changes in bile flow or bilirubin excretion.

Choice B reason:

While cholecystitis can lead to malabsorption of nutrients, it is not the primary cause of changes in stool color to pale.

Choice C reason:

This statement is correct. Cholecystitis can obstruct the bile duct, leading to a decrease in bilirubin excretion. Bilirubin gives urine its characteristic color, and when excretion is reduced, the urine becomes darker (brownish). Likewise, the absence of bilirubin in the stool leads to pale-colored or clay-colored stools.

Choice D reason:

Dehydration may occur in some cases of cholecystitis, but it is not the primary cause of changes in urine and stool color.

Choice A reason:

Gastroenteritis typically presents with symptoms such as diarrhea, vomiting, and abdominal cramps. It does not cause jaundice or severe right upper quadrant pain.

Choice B reason:

This statement is correct. Cholecystitis with cholangitis is characterized by severe right upper quadrant abdominal pain, fever, and jaundice. Cholangitis is an inflammation of the bile ducts, often caused by gallstone migration and obstruction.

Choice C reason:

A urinary tract infection may cause symptoms such as burning urination and frequent urination but does not present with right upper quadrant abdominal pain or jaundice.

Choice D reason:

GERD is a condition characterized by acid reflux and heartburn. It does not cause severe right upper quadrant abdominal pain or jaundice.
