A nurse cares for a client who suffered a myocardial infarction two (2) days ago. A high pitched, scratchy, scraping sound is he
ard that increase with exhalation and when the client leans forward. The nurse recognizes this sound as a result of what process occurring within the pericardium? Incompetent mitral valve Inability of the atria to contract Inflammation of the pericardial sac Increased pressure within the ventricle
<h2>Inflammation of the pericardial sac is the process that would have occurred within the pericardium.</h2>
Explanation:
Post myocardial infarction (MI), pericardial inflammation or early pericarditis is a complication that usually occurs within the first 24-96 hour time period.
The high-pitched, scratchy, scraping sound heard with an increase in exhalation when the client leans forward is due to the increased pericardial frictional rub of the inflamed pericardial layers in the pericardial sac.
These heart sounds are typical of pericarditis and can be best heard during inspiration as well as forced expiration with the patient in the forward-leaning position.
And that's going to happen someday! The Andromeda galaxy is currently racing toward our Milky Way at a speed of about 70 miles (110 km) per second. Ultimately, the two galaxies will collide and merge.
