To Assess the Patient with Pericarditis for the Presence of a Pericardial

To assess the patient with pericarditis for the presence of a pericardial friction rub, the nurse should

A) place the diaphragm of the stethoscope at the lower left sternal border of the chest.
B) ask the patient to stop breathing during auscultation to distinguish the sound from a pleural friction rub.
C) use the diaphragm of the stethoscope to listen for a rumbling, low-pitched, systolic sound.
D) feel the precordial area with the palm of the hand to detect vibration with cardiac contraction.
