Question

While counseling a patient about the adverse effects of first-generation antihistamines, the nurse practitioner advises that all of the following usually occur except:

a) Sedation.
b) Dry mouth.
c) Pruritus.
d) Urinary retention.

Answer 1

The adverse effects of first-generation antihistamines include sedation, dry mouth, and urinary retention. Pruritus, or itching, is not one of the usual side effects. First-generation antihistamines primarily block histamine receptors in the body to alleviate allergy symptoms.

Step-by-step explanation:

The adverse effects of first-generation antihistamines include sedation, dry mouth, and urinary retention. However, pruritus, which refers to itching, is not one of the usual side effects of first-generation antihistamines. These medications primarily work by blocking histamine receptors in the body, which helps alleviate symptoms of allergies such as sneezing and nasal congestion.
