WEEK 9 RESPI Flashcards
Inflammation of the nasal cavity
Seasonal rhinitis
Called hay fever
Seasonal rhinitis
Viruses invade the tissues of upper respiratory tract
Common cold
Common cold.
Release of ____ and _____ causing an inflammatory response
Histamine
Prostaglandin
Chemical released during inflammation that increases secretions and narrow airways
Histamines
Extravascular smooth muscle and lining the nasal activity are constricted
H1 receptor
Increase in gastric secretions (peptic ulcer)
H2 receptor
Relief of nausea and vomiting ( motion sickness)
Meclizine
Bronchodilators and antiasthmatics
Xantines
Sympatomimetics
Anticholinergics
Reversible bronchospasm, inflammation and hyperactive airways
Asthma
Triggered by allergens or nonallergic inhaled irritants or by factors such as exercise and emotions
Hyperactivity
Life-threatening bronchospasm that do not respond to usual treatment
Status asthmaticus
Direct effect on the smooth muscle of the respiratory tract ( bronchi and blood vessels)
Xanthines
Affecting the mobilization of calcium within the cells, stimulating prostaglandins results is smooth muscle relaxation
Xanthines
Inhibit the release of slow reacting substance of anaphylaxis and histamines
Xanthines
Mimic the effect of sns
Sympathomimetic
Dilation of the bronchi with increased rate and depth of respiration
Sympathomimetic
Beta2 adrenergic agonist to receptors
Action is more selective (activates only the b2 receptors)
Albuterol sulfate (proventil)
Patients who cannot tolerate the sympathetic effects of sympathomimetics might respond to the anticholinergic drugs (ipratropium:atrovent) and (tiotropium:spiriva)
Anticholinergics
Used as bronchodilators because of their efrect on the vagus nerve, which sis to block or antagonize the action of the acetylcholine
Anticholinergic
Anticholinergic nursing implementation
Oral drug with food or milk
Use it 30 to 60 mins before exercising
Not to exceed 12 inhalations in 24 hours
Selectively and competitively block zafirlukast and montelukast or antagonize zileutom receptors for the production of luekitrienes d4 and e4
Leukotriene receptor antagonist
Drugs block many of the signs and symptoms of asthma
- Neutrophil & eosinophil migration
- Neutrophil & monocyte aggregation
- Leukocyte adhesion
- Increased capillary permeability
- Smooth muscle contraction
Occurs when the epithelial lining of the sinus cavities becomes inflamed
Sinusitis
