Chapter 10.1 Flashcards

1
Q
  1. Compare the advantages and disadvantages of drug delivery methods for respiratory medications.
A

All of these routes will affect other tissues in the body.

inhaling is better at delivering drugs directly to lungs. Fewer side effects

16
Q
  1. List the major adverse effects of the mucolytics and expectorants.
A

nausea, vomiting, irritation of mouth

17
Q
  1. State the mechanism of action of beta-adrenergic agonists in the management of respiratory disorders.
A

stimulate beta 2 receptors on airway smooth muscle increasing intracellular production of cAMP. cAMP initiates bronchodilation

18
Q
  1. Classify the following agents as selective or nonselective beta-agonists: epinephrine, albuterol, salmeterol, metaproterenol.
A

Nonselective: epinephrine
Selective: albuterol, salmeterol, metaproterenol.

19
Q
  1. State the duration of action of the following inhaled beta-agonists: albuterol and salmeterol
A

albuterol: onset: 5-15 minutes peak: 1 hour duration: 3-6 hours
Salmeterol onset: 10-25 minutes Peak: 3-4 hours duration: 12 hours

20
Q
  1. List the major adverse effects of beta-agonists.
A

bronchoconstriction, increased heart rate, nervousness or anxiety

21
Q
  1. List the primary concerns of the physical therapist for patients using beta-agonists for upper respiratory tract disorders.
A

look for signs of overuse and use before postural drainage, increased heart rate and blood pressure

22
Q
  1. State the mechanism of action of the xanthines (theophylline and aminophylline).
A

aminophylline is converted to theophylline in body

theophylline: powerful bronchodilator

23
Q
  1. State the mechanism of action of anticholinergic drugs in the management of respiratory disorders.
A

blocks acetylcholine receptors.

24
Q
  1. List the common adverse effects of anticholinergic drugs in the management of respiratory disorders.
A

dry mouth, constipation, tachycardia, confusion

25
Q
  1. Place the following agents in their proper therapeutic categories: benzonatate, codeine, dextromethorphan, hydrocodone, cetirizine, loratadine, chlorpheniramine, diphenhydramine, epinephrine, pseudoephedrine, phenylephrine, acetylcysteine, dornase alfa, guaifenesin, albuterol, metaproterenol, salmeterol, theophylline, aminophylline, ipratropium, and tiotropium.
A

benzonatate, codeine, dextromethorphan, hydrocodone are antitussives and are cough relievers
cetirizine, loratadine, chlorpheniramine, diphenhydramine are antihistamines
acetylcysteine, dornase alfa are mucolytics
guaifenesin is an expectorant
albuterol, metaproterenol, salmeterol are selective beta agonists
theophylline, aminophylline are xanthines
ipratropium, and tiotropium are anticholinergic drugs
epinephrine, phenylephrine and pseudoephedrine are decongestants
epinephrine is also a selective beta agonist
