A child with allergic rhinitis is prescribed a nasal antihistamine spray. When advising the parents about the use of the sprays, what should the nurse explain about the rebound phenomenon?
A) It causes a permanent increase in nasal secretions.
B) It causes reflux of gastric contents into the esophagus.
C) It causes an increase in nasal secretions after an initial decrease.
D) It causes a decrease in histamine release after an initial increase.
C
Feedback:
Review with the parents that if nasal antihistamine sprays are given for more than 3 days, a rebound effect can occur. The nasal mucosa becomes more edematous rather than less edematous, and symptoms will appear to worsen rather than improve. The rebound phenomenon does not cause a permanent increase in nasal secretions, reflux of gastric contents into the esophagus, or a decrease in histamine release after an initial increase.
