what order should a nurse give bronchodialators when multiple drugs are used
1. Adrenergic bronchodilator
2. ipratropium (Atrovent)
3. Steroid
What are the nursing implicaitons for bronchodilators
Check P/R before and after admin, monitor theraputic effects, lung sounds
What it the pt. teaching for bronchodilators
do not exceed dose, use, FF and avoid caffeine, use bronchodilator first, B/P, oral meds w/food, O2 sats
What are the actions of antitussives
relieve or decrease the frequency of cough by...
depressing cough centers in mudulla
anesthetizing stretch receptors in respiratory passageways
What are the uses for antitussives
decrease frequesncy of non-productive cough
What are the side effects of antitussives
N/V, drowsiness and respiratory deprssion with codeine
benzonatate (Tessalon)
dydrocodone (Hycodan)
diphenhydramine (Benylin)
What are the nursing implications for antitussives
Chronic use, liquefy secretions with FF and humidify air, drowsiness- safty percautions, avoid taking w/water,
What are the actions of expectorants
liquefy respiratory secretions and DO NOT stimulate caugh
What are the uses for expectorants
Helps clear airway i.e.,COPD and bronchitis
guaifenesen (Hytuss, Robitussin)
What are the nursing implications for expectorants
monitor type and frequency of cough, keep pt. hydrated
What are the actions of antacids
Neutralize acidity
What are the uses for antacids
relieve pain associated with excessive HCl in stomach
What are the actions of systemic antacids
dissolve in gastric juices, absorbed into blood stream and alters electrolyte/pH balance, systemic alkalosis
What are the actions of nonsystemic antacids
not digested and insoluble
What are the nursing implications for nonsystemic antacids
mask severe problems, large amounts of sodium, take 1-2hr after meal
aluminum hydroxide (Amphogel)
aluminum & magnesium hydroxide (Maalox, Mylanta)
nonsystemic antacids
What is the actions of H2 antagonist and Proton Pump Inhibitors
inhibit action of histamine, thus reducing HCl secreations
