Respiratory Drugs Flashcards
Increases or liquefies respiratory secretions to aid in the clearing of airway for patients with tenacious secretions.
Mucolytics
Decreases the inflammatory activity in the bronchial wall and inhibits constriction of airway.
Intranasal Glucocorticoids (Steroids)
TRUE OR FALSE
Cromolyn sodium is an inhaled nonsteroidal anti-allergy agent and a mast cell stabilizer.
TRUE
A client is to begin taking Rifampin (Rifadin). The nurse correctly teaches the client this medication:
A. Is to be discontinued after three months.
B. Is to be taken with food and antacids.
C. Take an additional dose once with skip dose.

D. Will cause orange discoloration of sweat, urine, and feces
A nurse is giving teachings to a client receiving Desloratadine (Clarinex). Which of the following statements made by the client will need further instructions?
A. “I can eat gum after I drink the medicine”.
B. “I can take the medicine on an empty stomach.”
C. “I should avoid using alcohol”.
D. “I will avoid driving while using this medication”.
B. “I can take the medicine on an empty stomach.”
It blocks the action of acetylcholine at the vagus nerve and then relaxation of the smooth muscle in the bronchi occurs causing bronchodilation.
Anticholinergic
What drug has the mechanism of action of competing with histamine for receptor sites which then prevents a histamine response? It also reduces nasopharyngeal secretions, itching, and sneezing.
Antihistamines
What are the possible ways of administering nasal decongestants?
Through nasal sprays, nasal drops, tablet, capsule, and liquid form of drugs
What are the four most common side effects of taking first-generation antihistamines?
Drowsiness, dry mouth, dizziness, and GI distress
It is an inflammation of the mucous membranes of one or more of the maxillary, frontal, ethmoid, or sphenoidal sinuses.
Histamine
This loosen bronchial secretions by reducing surface tension of secretions
Expectorants
This act on cough-control center in the medulla to suppress cough reflex
Antitussives
Antihistamine drugs that has less sedation and fewer anticholinergic effects
Second-generation histamines (Cetirizine, Fexofenadine, Loratidine)
A progressive lung disease caused by cigarette smoking, atmospheric contaminants.
Emphysema
It is the acute inflammation of the mucous membranes of the nose.
Acute Rhinitis
It facilitates smooth muscle relaxation and inhibits mast cells degranulation
Cyclic Adenosine Monophosphate
Give 3 examples of second-generation antihistamines
Cetirizine (Zyrtec), Fexofenadine (Allegra), Loratadine (Claritin)
Has antiinflammatory effect and suppresses the release of of histamine
Cromolyn and Nedocromil
It produces nasal vascular vasoconstriction of respiratory tract mucosa and shrinks nasal mucus membranes
Nasal Decongestants
An example of first generation antihistamine
Diphenhydramine (Benadryl)
It reduces inflammatory process to decrease bronchoconstriction
Leukotriene Receptor Antagonist
Give 3 examples of nasal decongestants
Oxymetazoline
Naphazoline
Pseudoephedrine
What are the 5 different medications for rhinitis?
Antihistamine Nasal decongestants Intranasal glucocorticoids Expectorants Mucolytics
What are the 7 drugs used for the lower respiratory system?
Bronchodilators cAMP (Cyclic Adenosine Monophosphate) Beta2 - Adrenergic Agonist Anticholinergic Xanthines Leukotriene receptor antagonist Cromolyn & nedocromil
Long term widening of the of the airways of the lungs
Bronchiectasis
Airway obstruction with increased airway resistance to airflow with bronchoconstriction/spasms/ increased mucous secretions
Chronic obstructive pulmonary disease (COPD)
Inhibit the enzyme phosphodiesterase, increases cAMP, and bronchodilation
Xanthines
Which of these foods does not contain Xanthine? A. Coffee B. Tea C. Cola D. Bread
D. Bread
An autoimmune disease that presents muscular weakness and fatigue that worsens with exercise A. Myasthenia Gravis B. Mucolytics C. Dry Mouth D. Rheumatoid Arthritis
A. Myasthenia Gravis
Which of these is an upper respiratory infection? A. Emphysema B. Chronic Bronchitis C. Common cold D. COPD
C. Common Cold
