Bronchial hyper responsiveness occurs at A. Early B. Late C. Chronic D. Both A/B E. Both B/C F. All phases G. None	1. Both Early and Late phase 2. Chronic phase * All phases listed here * Allergens trigger hyper responsiveness
Tracheal constriction occurs at A. Early B. Late C. Chronic D. Both A/B E. Both B/C F. All phases G. None	1. Could be all phases (F) and could be none (G) 2. Explanation: Tracheal constriction is not as important in asthma, b/c they aren’t that viable in asthma.
Allergens bind to IgE antibodies occur at A. Early B. Late C. Chronic D. Both A/B E. Both B/C F. All phases G. None	Early phase
Vasodilation occurs at A. Early B. Late C. Chronic D. Both A/B E. Both B/C F. All phases G. None	1. Both Early and Late phase 2. not all phases bc chronic remodel airway (scarring) and replace with connective tissues… so no vasodilation.

Which of these is true? 1. The smaller the particle size, the greater the chance the particles will get absorbed and will be in the alveoli 2. larger particles will not be able to get to the alveoli, so it will get to the throat	1. True 2. True
What is the role of LOX- 5?	Activation of 5-LOX stimulates production of leukotrienes that promote bronchoconstriction and inflammation

Some limitations of normal activity =/> 2 exacerbations requiring oral systemic corticosteroids per year.
Xteristics of Not Well Controlled (lung fx)	FEV1 or PEF 60 - 80% predicted or personal best
Xteristics of Very Poorly Controlled (snx)	1. Daily snxs 2. Nocturnal snxs =/> 4x per wk 3. Use ofinhaled, short acting B-agonists several times per day 4. Extreme limitations of normal activity
Xteristics of Very Poorly Controlled (lung fxs)	FEV1 or PEF < 60% predicted or personal best
