<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.

Explain why treehouses dont change in height as a tree grows
Dmitrij [34]
Treehouses are built on the stem and the three branches, which do not grow in length, only in width. Trees grow in length only in the area of the buds, which are located at the ends of branches. 
Maybe it is easier to understand this if you imagine that you put a small house replica on the palm of your hand and that your fingers are constantly growing from their tips.  So, the house on your palm would not move, only your fingers, (the analogy to the three top buds) would become longer.
