When a patient has a severe allergic reaction, a common prescribed drug is epinephrine. Which of the follow best explains the effects of epinephrine on a patient experiencing a severe allergic reaction?
A epinephrine binds to the beta-1 receptor. Activating the beta-1 receptor causes vasodilation and bronchoconstriction. Bronchoconstriction allows the patient to breath by relaxing the smooth muscle that is constricting the airway.
B Epinephrine binds to the beta-2 receptor. Activating the beta-2 receptor causes vasodilation and bronchodilation. Bronchodilation allows the patient to breath easier by relaxing the smooth muscle that is constricting the airway.
C Epinephrine binds to the alpha-1 receptor. Activating the alpha-1 receptor causes vasodilation and bronchodilation. Bronchodilation allows the patient to breath by relaxing the smooth muscle that is constricting the airway.
D Epinephrine binds to the beta-1 receptor. Activating the beta-1 receptor causes vasodilation and bronchodilation. Bronchodilation allows the patient to breath by relaxing the smooth muscle that is constricting the airway.
E Epinephrine binds to the beta-2 receptor. Activating the beta-2 receptor causes vasodilation and bronchoconstriction. Bronchoconstriction allows the patient to breath by relaxing the smooth muscle that is constricting the airway.
