Complete Solution
What is asthma and how does it occur? - ANSWER -chronic inflammatory
disorder of the airways
-intermittent and reversible obstruction of the bronchioles
-happens because of inflammation or hyper responsiveness that leads to
bronchoconstriction
What is the drug classification for albuterol? - ANSWER Beta2-adrenergic
agonist?
What are some other Beta2-adrenergic agonists other than albuterol? -
ANSWER -formoterol
-levalbuterol
-salmeterol
-terbutaline
What is the expected pharmacological action of albuterol? - ANSWER
-Selectively activate beta2-receptors in the bronchial smooth muscle,
therefore, causing bronchodilation.
-Bronchospasm is relieved, histamine inhibited, and ciliary motility increased.
What are the routes of albuterol and levalbuterol? - ANSWER Route:
,-inhaled (short acting)
-oral (long acting, albuterol)
What are the therapeutic uses of albuterol and levalbuterol? - ANSWER
Therapeutic uses:
-prevention of exercise induced asthma (30 minutes before)***
-inhaled, short-acting use of prevention of asthma
-treatment of bronchospasm
-long-term control of asthma***
What is the route for formoterol and salmeterol? - ANSWER inhaled, long
acting
What is the therapeutic use of formoterol and salmeterol? - ANSWER long
term control of asthma
What is the route for terbutaline? - ANSWER oral, long-acting
What is the therapeutic use of terbutaline? - ANSWER long term control of
asthma
What does an antitussive do? - ANSWER cough suppressant
What does a decongestant do? - ANSWER decrease overproduction of
secretions
What does an antihistamine do? - ANSWER block the release of histamines
What does an expectorant do? - ANSWER increase productive cough to clear
airways
, What does a mucolytic do? - ANSWER increase or liquifies secretions to aid in
clearing the airways
What are some complications of albuterol and what should an RN consider? -
ANSWER -tachycardia, angina: b/c of activation of alpha 1 receptors in heart
--observe for chest, jaw, or arm pain or palpitations and notify.
--check pulse and reporst increase of greater than 20-30 bpm
--avoid caffeine
-tremors: b/c of activation of beta2 receptors in skeletal muscle
--usually resolve with continued med use
What are the contraindications/precautions for albuterol? - ANSWER -PRC C
-tachydysrhythmia
-DM
-hyperthyroidism
-heart disease
-HTN
-angina
What are some drug interactions for albuterol? - ANSWER -use of
beta-adrenergic blockers can negate effects
-MAOIs and tricyclic antidepressants can increase risk of tachycardia and
angina
What can you educate the pt. about albuterol? - ANSWER -inhale
