Nokea
A pregnant woman presents with fever, chills, and abdominal pain localized to the right upper quadrant. On examination, she has tenderness in the right upper abdomen and a positive Murphy's sign. Which of the following conditions is the most likely cause of these symptoms?
Correct Answer: C
Rationale: The scenario described in the question is consistent with acute cholecystitis, which is inflammation of the gallbladder usually caused by an impacted gallstone in the cystic duct. The key clinical features of acute cholecystitis include fever, chills, right upper quadrant abdominal pain (which can be localized to the right upper quadrant), tenderness in the right upper abdomen, and a positive Murphy's sign (pain and inspiratory arrest upon palpation of the right upper quadrant). This condition is more common in pregnant women due to hormonal changes that can lead to gallstone formation and subsequent inflammation of the gallbladder. Ectopic pregnancy, pelvic inflammatory disease, and ovarian torsion typically present with different clinical features compared to those described in acute cholecystitis.
