A nurse is collecting data from a client who has acute cholecystitis. Which of the following findings should the nurse expect?

Acute cholecystitis is most commonly caused by obstruction of the cystic duct, usually from gallstones, leading to gallbladder inflammation, distention, and infection. The condition typically presents with characteristic right upper quadrant abdominal pain, often associated with nausea, vomiting, and fever. Pain may also radiate to the right shoulder or back due to diaphragmatic irritation. Recognizing the classic pain pattern is essential for timely diagnosis and management. Rationale: A. Increased abdominal discomfort prior to meals is more commonly associated with peptic ulcer disease rather than acute cholecystitis. In gallbladder inflammation, pain is typically triggered or worsened by fatty meals after eating, not before meals. This pattern does not align with the expected presentation of cholecystitis. B. Discomfort with urination is not associated with gallbladder inflammation. This symptom is more commonly linked to urinary tract infections or other urinary system disorders. Acute cholecystitis involves the hepatobiliary system and does not typically affect urinary function. C. Pain radiating to the jaw is more characteristic of cardiac ischemia, particularly angina or myocardial infarction. Although referred pain can occur in various conditions, cholecystitis typically causes referred pain to the right shoulder or back due to phrenic nerve irritation, not the jaw. D. Pain in the right upper abdomen is the hallmark symptom of acute cholecystitis. This occurs due to inflammation and distention of the gallbladder following obstruction of bile flow. The pain is often severe, steady, and may worsen after fatty meals, making it the most expected and clinically significant finding.
