The medication racemic epinephrine (Micronefrin, Vaponefrin) is given to a patient with LTB because it:
a. is an effective bronchodilator.
b. causes mucosal vasoconstriction.
c. causes bradycardia.
d. has an appealing taste and smell.
B
Racemic epinephrine constricts the blood vessels in the mucous membrane of the airway. This helps to counteract the airway inflammation found in a patient with LTB. Although the drug is also a bronchodilator, it is not given for this effect. The drug may cause tachycardia as a side effect. There should not be any particular taste to the drug because it is nebulized.
