Okay, so we can first talk about why did mrs.
00:03
Say return to the ed? so she likely returned to the ed because her initial treatment was insufficient for the severity of her asthma exacerbation.
00:28
And now we can talk about the path physiology of the exacerbation.
00:32
So asthma exacerbation occurs when airways become inflamed and constricted due to triggers such as cigarette smoke in mrs .ay's case.
00:48
And this leads to increased mucus production and bronchial.
00:52
Swelling, severely reducing airflow.
00:56
And the inability to expel co2 and poor oxygenation can lead to respiratory distress, as evident from her physical signs of using accessory muscles to breathe and no air movement in the lower lung fields.
01:12
And we can talk about the nursing intervention priorities.
01:16
So first is the immediate administration of fast -acting broncholidilators.
01:29
And then then you can use cortical steroids to reduce airway inflammation.
01:45
And then you can do oxygen therapy to improve hypoxemia...
