A patient tells a nurse that antihistamines help relieve cold symptoms and wants to know why they are not recommended or prescribed for this purpose
The nurse tells the patient that antihis-tamines provide only mild relief from some cold symptoms by: a. anticholinergic properties that decrease rhinorrhea.
b. blocking H1 receptors in nasal passages.
c. reducing secretions at H2 receptor sites.
d. having sedative effects, which help pa-tients rest and sleep.
B
Histamine does not mediate cold symptoms, so antihistamines do not provide relief through H1 blockade. Their anticholinergic effects at muscarinic receptor sites can moderately reduce rhi-norrhea, so some patients may experience some relief of this symptom. H1-receptor sites do not play a role in cold symptoms. H2-receptor sites do not play a role in cold symptoms. Sedative side effects do not alleviate cold symptoms.
