An NP is evaluating an adult patient who reports intermittent abdominal pain lasting minutes to hours at a time, nausea, and vomiting, which of the following locations of the abdominal pain would support the NP's suspicion of biliary colic?

Biliary colic is caused by transient obstruction of the cystic duct by a gallstone, resulting in intermittent, crampy pain that typically localizes to the right upper quadrant. A hallmark feature is radiation of the pain to the right shoulder or right scapula, which occurs due to diaphragmatic irritation and referred pain traveling along the phrenic nerve pathway. This pattern of right upper quadrant pain radiating to the right shoulder strongly supports the diagnosis of biliary colic and differentiates it from other causes of abdominal pain. Epigastric pain that radiates to the back is more characteristic of pancreatitis or a posterior penetrating peptic ulcer. The radiation to the back in a band-like or boring pattern, especially with nausea and vomiting after meals, points toward pancreatic pathology rather than gallbladder disease. Periumbilical pain that migrates to the right lower quadrant is the classic presentation of acute appendicitis, following the well-known progression from visceral pain around the umbilicus to somatic pain localized at McBurney's point. Left lower quadrant or pelvic pain is more suggestive of conditions such as diverticulitis in older patients, ovarian pathology, or irritable bowel syndrome. Understanding the referred pain patterns unique to each abdominal organ is essential for correctly localizing the source of pain during clinical assessment.
