A client diagnosed with allergic rhinitis is prescribed an antihistamine to assist with symptoms. Which of the following medications below would be considered a second-generation antihistamine?
Correct answer
A
Rationale
The correct answer is A: cetirizine (Zyrtec). Second-generation antihistamines like cetirizine have less sedation and longer duration of action compared to first-generation antihistamines like chlorpheniramine (B) and diphenhydramine (C). Montelukast (D) is a leukotriene receptor antagonist used for asthma and allergic rhinitis, not a second-generation antihistamine.
