Question 1 of 5
A patient comes to the clinic complaining of seasonal rhinitis. What adrenergic agonist will be prescribed for seasonal rhinitis?
Correct Answer: C
Rationale: The correct answer is C: Ephedrine. Ephedrine is a mixed-acting adrenergic agonist that acts on both alpha and beta receptors. In seasonal rhinitis, ephedrine can help relieve nasal congestion by constricting blood vessels in the nasal passages (via alpha-1 receptors) and reducing inflammation (via beta-2 receptors). Norepinephrine (
A) primarily acts on alpha receptors and is not commonly used for rhinitis. Dopamine (
B) primarily acts on dopamine receptors and is not effective for rhinitis. Dobutamine (
D) is a beta-1 agonist used for heart failure and not indicated for rhinitis.
