Flashcards in Respiratory Agents Deck (23):
1

inflammation of the throat or "sore throat"

Acute Pharyngitis

2

acute inflammation of the mucous membranes of the nose usually accompanying the common cold

Acute Rhinitis

3

inflammation of the mucous membranes of the nose caused by pollen or a foreign substance, also called "hay fever"

Allergic Rhinitis

4

occurs when there is abnormal dilation of the bronchi and bronchioles secondary to frequent infection and inflammation

Bronchiectasis

5

bronchoconstriction that results when the lung tissue is exposed to extrinsic or intrinsic factors that stimulate a bronchoconstrictive response, also called "asthmatic attack"

Bronchospasm

6

progressive lung disease caused by smoking or chronic lung infections...bronchial inflammation & excessive mucous secretion result in airway obsruction

Chronic Bronchitis

7

progressive lung disease caused by cigarette smoking, atmospheric contaminants or lack of alpha-antitrypsin protein that inhibits proteolytic enzymes that destroy alveoli

Emphysema

8

drugs in the corticosteroid familyused to treat respiratory disorders, particularly asthma

Glucocorticoids

9

rebound vasodilation instead of vasoconstriction caused by irritation of the nasal mucosa

Rebound Nasal Congestion

10

a decrease in total lung capacity as a result of fluid accumulation or loss of elasticity of the lung

Restrictive Lung Disease

11

inflammation of the mucous membranes of one or more of the maxillary, frontal, ethmoid, or sphenoid sinuses

Sinusitis

12

Nursing Interventions for Common Cold Drugs

(1) Monitor vital signs (2) Observe color of secretions (3) Advise patient that hypotension & hyperpyrexia may occur when dextromethorphan is taken with MAOIs (4) Advise patients to read labels on OTC products (5) Encourage older patient to contact provider about OTC drugs (6) Direct patient not to drive when first beginning meds (7) Direct patient to store meds out of reach of children

13

relaxes smooth muscles of bronchi, bronchioles, & pulmonary blood vessels by inhibiting the enzyme phosphodiesterase, resulting in cAMP, which promotes bronchodilation

Action of Theophylline

14

Side Effects of Theophylline

anorexia, N&V, gastric pain, GI bleed, nervousness, dizziness, HA, iriitability, dysrythmias, tachycardia, palpitations, hypotension, convulsions, cardiorespiratory collapse

15

Therapeutic Serum Level of Theophylline

10-20 mcg/mL

16

Alpha1 Agonists (Sympathomimetics) Therapeutic Effect

increases cyclic AMP in lung tissue resulting in bronchodilation, restores circulation, and increases airway patency

17

Leukotiene Antagonists Therapeutic Effect

block leukotrienes from interacting with receptors to reduce inflammatory process & decrease bronchoconstriction

18

Glucocorticoids Therapeutic Effect

antiinflammatory effect; used to treat asthma but not for severe attacks

19

Cromolyn Therapeutic Effect

antiinflammatory effect and suppression of the release of histamine; prophylactic treatment of bronchial asthma

20

Anticholinergics Therapeutic Effect

dilates bronchioles; administered through aerosol inhaler

21

Mucolytics Therapeutic Effect

liquefies and loosens thick & sticky mucous secretions; adminstered 5 min after bronchodilator (cystic fibrosis)

22

Nursing Assessment for COPD, Asthma & Lung Disease Drugs

respiratory & lung status, breathing effort, cough, sputum, breath sounds, history of acute episodes, O2 sat or ABGs, medications, patient's home environment

23

Nursing Interventions for COPD, Asthma & Lung Disease Drugs

teach correct use/technique of administration (inhalers), clear airway, force fluids, flu vaccine, STOP SMOKING
