Multiple Choice

Which best describes the main symptom of acute cholecystitis?

The main thing this question tests is recognizing where gallbladder inflammation tends to hurt and how that pain presents. Acute cholecystitis typically causes intense pain in the upper right part of the abdomen that can radiate to the right shoulder or back. This pattern happens because the gallbladder sits under the liver and irritation can involve the diaphragm and nearby nerves, so the pain isn’t just localized there—it can reach the shoulder. The pain is usually steady and may be accompanied by nausea, vomiting, and sometimes fever. That makes the description of sudden, sharp pain in the upper right abdomen that radiates to the right shoulder the best match for this condition. The other options describe symptoms more consistent with different problems: a gradual dull ache in the lower abdomen isn’t characteristic of gallbladder inflammation; fever with no abdominal pain misses the key RUQ finding; painful urination with blood points to urinary tract issues like a UTI or kidney stones rather than cholecystitis.
