護理師評估一位急性胰臟炎病患，應預期出現哪項臨床表現？
A nurse is assessing a client with acute pancreatitis. Which clinical manifestation should the nurse expect?
- APain that improves when leaning forward✓ 正解身體前傾時疼痛減輕
- BLeft upper quadrant pain radiating to the back左上腹疼痛並輻射至背部
- CBright red rectal bleeding鮮紅色直腸出血
- DIncreased bowel sounds腸鳴音增加
急性胰臟炎的兩大特徵性疼痛表現皆為臨床事實：上腹／左上腹痛放射至背部（B），以及身體前傾或胎兒姿勢可緩解疼痛（A）。本題為單選題，A「身體前傾緩解疼痛」屬於具姿勢特異性的鑑別徵象，於 NCLEX 答題中常被選為最具特徵性的單一表現。其他選項：C 鮮紅色直腸出血與胰臟炎無直接關聯；D 急性胰臟炎常因麻痺性腸阻塞使腸音減弱或消失，而非增加。
The two characteristic pain features of acute pancreatitis are both clinical facts: epigastric or left upper quadrant pain radiating to the back (B), and pain that is relieved by leaning forward or assuming a fetal position (A). This is a single-best-answer item; option A, 'pain relieved by leaning forward,' is a positionally specific differentiating sign and is often selected on NCLEX as the most characteristic single finding. Regarding the other options: B, bright red rectal bleeding, is not directly associated with pancreatitis; D, acute pancreatitis often causes paralytic ileus, so bowel sounds are diminished or absent rather than increased.
