| 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 |
