Question 1

Beta2 Agonists Action

Answer 1

Stimulate the bronchial smooth muscle to dilate relaxing the brochioles. the stimulants and reuptake inhibitors increase levels of endogenous catecholamine.

Question 2

what are Beta2 agonists used for

Answer 2

reversible airway obstruction caused by bronchospasm

Question 3

What is an adverse effect caused from excessive use of the inhalant medication

Answer 3

paradoxical bronchospasm

Question 4

What are some adverse effects of Beta2?

Answer 4

nausea, vomiting, restlessness, tachycardia and increased respirations, nervousness, headache, palpitations, and hyperglycemia

Question 5

What are the 4 contraindications/warning/cautions of Beta2 agonist?

Answer 5

cardiac arrythmias, narrow angle glaucoma, beta blocker use (blocks all betas including beta2 which inhibits effects), caution for pts with diabetes mellitus (can increase serum blood glucose)

Question 6

Muscarine Antagonist type and action

Answer 6

anticholinergic. antagonizes acetylcholine receptors producing bronchodilation

Question 7

Use of muscarine antagonists (2)

Answer 7

symptomatic relief or prevention of bronchial asthma and management of COPD

Question 8

Answer 8

drowsiness/sedation/flushed face, blurred vision/mydriasis, urinary retention, confusion/delirium, hallucinations, increased temp/HR, dry mouth

Question 10

What does Leukotriene do?

Answer 10

Broncho constrictive substance released by the body during inflammation. Antagonist results in bronchodilation

Question 11

What does a Mast Cell Stabilizer do?

Answer 11

Inhibit the release of substances that cause bronchoconstriction and inflammation from the mast cells in respiratory tract

Question 12

What are the two uses for Leukotriene Antagonist and Mast Cell Stabilizers

Answer 12

Treatment of Asthma or COPD

Question 13

What are the adverse effects of Leukotriene Antagonist and Mast Cell Stabilizers

Answer 13

Headache, dizziness, unpleasant taste, and fatigue

Question 14

What are some contraindications/warnings/cautions for Leukotriene Antagonist and Mast Cell Stabilizers?

Answer 14

Acute asthma/bronchospasms, aspirin sensitive asthmatics

Question 15

What action do inhaled corticosteroids have?

Answer 15

produce profound and varied metabolic effect, modify the normal immune response, and suppress inflammation
