Question | Answer |
---|---|
bronchodilators | beta-adrenergic agonists or sympathomimetics, Xanthine or Methylxanthenes, |
action of beta adrenergic agonists | stimulates smoothe muscles to cause bronchodilation |
beta 2 | receptors in lungs |
beta 1 | receptors in heart |
rescue inhalers | epinephrine (Primatene mist), terbutaline (Brethine), Albuterol (Provental, Ventolin), Salmeterol (Serevent) |
Inhaled drugs | rapid onset, short duration |
Oral bronchodilators | not effective in acute attacks |
action of Xanthine or Methylxanthenes | smoothe muscle relaxant, inhibits phosphodiesterase |
examples of xanthine bronchodilators | theophylline (Theodur or theolair), Aminophylline, caffeine |
monitor for these with xanthine drugs | toxicity, blood levels |
n/c for xanthines | toxicity, tachycardia, restlessness and insomnia, seizures, anorexia, give with meals |
Action of Anticholinergics | blocks parasympathetic input, decreases bronchial constriction, not used for acute attacks! |
Examples of Anticholinergics | Ipratropium bromide (Atrovent), and Combivent (albuterol and atrovent) |
Anticholinergics | used before surgeries and broncoscopies to prevent vagal stimulation and decrease secretions |
n/c of anticholinergics | dry secretions, urinary retention, NOT used in clients with glaucoma or urinary obstructions |
Anti-inplammatory agents | corticosteroids |
action of corticosteroids | decreases the inflammatory and immune responses |
systemic corticosteroids | prednisone and methylprednisone |
what to avoid with systemic corticosteroids | never ever stop abruptly, and taper when switching from systemic to inhaled steroids |
s/e of corticosteroids | weight gain, electrolyte imbalances(decreased Potassium), hypertension, hyperglycemia from decreased effects of diabetic agents, thin skin, decreased healing, bone loss |
inhaled steroids | flovent, aerobid, azmacort, pulmicort, vanceril, advair diskus |
action of inhaled steroids | limited to respiratory system |
important teaching for inhaled steroids | rinse mouth after use, and wash chamber and mouthpiece! |
combo drug inhaled via dry powder | advair diskus (corticosteroid and beta2 receptor agonist) |
Advair Diskus | not for children, not for acute attacks, never EXHALE into diskus |
Mast cell stabilizers (antiinflammatory agent) | Intal - prevent histamine release Tilade - PREVENTS inflammation from occurring |
Monoclonal antibodies (anti-inflammatory agent) | Xolair - prevents allergens from triggering asthmatic attack |
Antileukotrinine Agents action | leukotriene modifiers, mast cell stabilizers, decreases airway edema |
Antileukotrinine Agent drugs | PO- Accolate and Singulair |
Antileukotrinine Agent n/c | not rescue drugs, instruct client to continue even when no symptoms, monitor LFT |
S/e of antileukotrinines | n/v, (take one to two hours after meals), headaches, liver dysfunctions (LFT) |
Antitussives | cough suppressants |
Narcotic Antitussives | codeine, hydrocodone |
non-narcotic antitussives | benzonatate (Tessalon), dextramethorphan (Benylin) |
Do not use antitussives with.... | productive cough |
n/c for antitussives | sedation, dry mouth, constipation, check for adequate hydration |
Mucolytics and Expectorants action | thins out and loosens secretions, making them easier to expectorate |
Mucolytics and Expectorant drugs | acetylcysteine (Mucomyst)nebulizer, Guaifenesin(Naldecon)oral. |
mucolytics not used with | asthma d/t lack of secretions |
nursinf diagnosis with impaired respiratory functions | *Impaired Gas exchange, *Activity Intolerance, *Imbalanced Nutrition, *Risk for Infection, *Home Maintenance Management |
