Correct answer
C
Rationale
The correct answer is C: Sustained use of nasal decongestants over several days may result in rebound congestion. Rebound congestion occurs when the nasal passages become more congested after the effects of the decongestant wear off, leading to a cycle of worsening congestion. This phenomenon is commonly associated with the prolonged use of topical decongestants like oxymetazoline. The patient's worsening nasal congestion despite using oxymetazoline every 2 to 4 hours for 5 days suggests rebound congestion. Choice A is incorrect because hourly administration of oxymetazoline is not recommended due to the risk of adverse effects. Choice B is incorrect as oxymetazoline is an effective decongestant when used appropriately. Choice D is incorrect as idiosyncratic reactions are unpredictable and rare.
