Which drug will the primary health care provider preA patient who reports nasal congestion is prescribed naphazoline, 2 drops in each nostril, every 6 hours, for 5 days. The patient reports increased nasal congestion after 10 days. On assessment the nurse learns that the patient had increased the drug frequency to every 3 hours for 10 days. Which statement describes what the nurse would interpret from this information?

Congestion, as a symptom of upper respiratory tract diseases including seasonal and perennial allergic rhinitis, acute and chronic rhinosinusitis, and nasal polyposis, is principally caused by mucosal inflammation. Though effective pharmacotherapy options exist, no agent is universally efficacious; therapeutic decisions must account for individual patient preferences. Oral H1-antihistamines, though effective for the common symptoms of allergic rhinitis, have modest decongestant action, as do leukotriene receptor antagonists. Intranasal antihistamines appear to improve congestion better than oral forms. Topical decongestants reduce congestion associated with allergic rhinitis, but local adverse effects make them unsuitable for long-term use. Oral decongestants show some efficacy against congestion in allergic rhinitis and the common cold, and can be combined with oral antihistamines.
