Answer to Question 1

Ans: D
Feedback:
The nurse should assure the client that azelastine has very little sedative effect; it is a second-generation antihistamine with little effect on central nervous system (CNS) depression. Brompheniramine, clemastine, and chlorpheniramine are first-generation antihistamines. Sedation is seen more often with first-generation antihistamines.

Answer to Question 2

Ans: C, D
Feedback:
Loratadine and cetirizine are second-generation antihistamines, which can be less sedating than first-generation antihistamines, like chlorpheniramine, diphenhydramine, and clemastine. Phenylephrine is a decongestant used to treat nasal congestion.
