A nurse is reinforcing teaching with a client who needs to have a cholecystectomy due to gallstones. Which of the following is the best response from the nurse to explain what caused this problem?

Choice A rationale While the gallbladder can become infected (cholecystitis), gallstones are the most common underlying cause for cholecystectomy. Viral infections are not the typical or primary cause of gallstones or the subsequent inflammation (cholecystitis) that necessitates the removal of the gallbladder. The underlying mechanism is often related to bile composition and stasis. Choice B rationale Cholecystectomy is commonly performed due to symptomatic cholelithiasis (gallstones), which typically presents when a gallstone obstructs the cystic duct, causing bile to back up and irritate the gallbladder wall. This obstruction and resulting irritation lead to inflammation (acute cholecystitis), causing pain and potentially leading to infection or perforation if left untreated. Choice C rationale Although tumors can block bile flow and necessitate gallbladder removal, gallstones are overwhelmingly the most frequent reason for cholecystectomy. Tumors causing obstruction are a less common cause compared to the high prevalence of cholesterol or pigment gallstones blocking the cystic or common bile duct. Choice D rationale Gallstones themselves, which often consist primarily of cholesterol, can cause irritation and inflammation when they physically obstruct the outflow of bile from the gallbladder or bile ducts. The inflammation (cholecystitis) is not caused by the cholesterol component itself but by the physical mechanical obstruction and resulting irritation or stasis. —.
