albuterol/ beta 2 adrenergic agonists Flashcards
what is the category class of the drug Albuterol
beta 2 adrenergic agonists
what is the expected pharmacological action of beta 2 adrenergic agonists
acts by selectively activating the beta 2 receptors in the bronchial smooth muscle, resulting in bronchodilation
what is the route and onset of the drug albuterol when inhaled
inhaled; short-acting
what are the results when beta 2 adrenergic agonists activate beta 2 receptors
bronchospasm is relieved
histamine release is inhibited
ciliary motility is increased
what is the route and onset for albuterol when taken orally
oral- long-acting
what are the complications of albuterol
tachycardia (fast HR)
angina (chest pain)
tremors
how can oral agents of albuterol cause tachycardia and angina
oral agents of albuterol activate alpha 1 receptors in the heart which may cause tachycardia and angina
if a patient is experiencing tachycardia and angina when taking albuterol what nursing action may need to take place
albuterol dosage may need to be reduced
because albuterol can cause tachycardia and angina what symptoms should the patient observe and when should they notify the provider
if they observe chest, jaw, or arm pain or palpitations they should call the provider if they occur
what should a patient check while taking albuterol
check pulse
a patient taking albuterol checks their pulse, when should they report
if the pulse rate is greater than 20 to 30 per minute
what drink should be avoided when taking albuterol
caffeine
why can albuterol cause tremors
activates beta 2 receptors in the skeletal muscle
if a patient reports tremors while taking albuterol what should you tell them
tremors usually resolve with continued medication use
if tremors while taking albuterol continues what may need to happen
dosage may need to be reduced
