Question 1 of 5
A nurse is providing an in-service about medications that are first-generation antihistamines. Which of the following medications should the nurse include in her in-service?
Correct Answer: B
Rationale: The correct answer is B: Diphenhydramine. First-generation antihistamines like diphenhydramine have sedative effects due to their ability to cross the blood-brain barrier and bind to central H1 receptors. They are commonly used for allergic reactions and sleep disorders. Albuterol (
A) is a beta-2 agonist used for bronchodilation in asthma, not an antihistamine. Certirizine (
C) is a second-generation antihistamine with less sedative effects. Codeine (
D) is an opioid used for pain relief, not an antihistamine.
