单项选择题
A client who suffered blunt chest trauma in a car accident complains of chest pain, which is exacerbated by deep inspiration. On auscultation, the nurse detects a pericardial friction rub--a classic sign of acute pericarditis. To relieve chest pain associated with pericarditis, the nurse should encourage the client to assume which position（）
A. Semi-Fowler’s.
B. Leaning forward while sitting.
C. Supine.
D. Prone.
答案
参考答案：B
解析：
When the client leans forward, the heart pulls away from the diaphragmatic pleurae of the lungs, helping relieve chest pain caused by pericarditis. The semi-Fowler’s, supine, and prone positions don’t cause this pulling-away action and therefore don’t relieve chest pain associated with pericarditis.
