What is asthma? - ANSWER-A heterogeneous disease, usually
characterized by chronic airway inflammation
Asthma causes what 3 things? - ANSWER-- airway
hyperresponsiveness - mucosal edema
- mucus production
The inflammation then leads to what specific symptoms? - ANSWER--
cough
- chest tightness
- wheezing
- dyspnea
What group of people are more prone to asthma? - ANSWER-- African
Americans and Hispanics
Is asthma reversible? - ANSWER-yes
What is the biggest predisposing factor for asthma? – ANSWER-
Allergies, but there are other triggers that are non-allergen related as
well
,What is the pathophysiology of asthma? - ANSWER-Mast cells, when
activated, will release mediators (which are chemicals that contain
histamine, bradykinin, etc.) that perpetuate the inflammatory
response causing increase blood flow, vasoconstriction, fluid leak
from vessels, attraction of WBC, mucus, and bronchoconstriction
During acute exacerbations of asthma, ____ occurs quickly to narrow
the airway in response to an exposure – ANSWER-
bronchoconstriction

, Prevention of asthma (4 things) - ANSWER-- Get tested and avoid
triggers
- A detailed work history evaluation to identify occupational triggers
- Standard asthma meds
- Compensation systems
Major complications of asthma - ANSWER-- Status asthmaticus
- Respiratory failure
- Pneumonia
- Atelectasis
Why do we give fluids to people with asthma? - ANSWER-They get
dehydrated from sweating and insensible fluids loss with
hyperventilation
Primary treatment of asthma focuses on what 3 things - ANSWER--
preventing impairment of lungs function
- minimizing symptoms
- preventing exacerbations
What condition can substantially increase exacerbation of asthma and
needs to be controlled? - ANSWER-anxiety
What is the first choice of meds for quick-relief of asthma? -
