What is the general name for allergic reactions that occur within the nasal chambers?

• A. Allergic rhinitis
• B. Sinusitis
• C. Bronchitis
• D. Rhinorrhea

Answer: (A)

Allergic reactions that occur within the nasal chambers are commonly referred to as allergic rhinitis. This condition is characterized by inflammation of the nasal mucosa due to exposure to allergens such as pollen, dust mites, pet dander, or mold. Symptoms typically include sneezing, itching, nasal congestion, and a runny nose, all of which result from the immune system's exaggerated response to these triggers.

The term allergic rhinitis effectively describes the specific area the allergic reaction affects (the nasal chambers) and the nature of the response (an allergy). Other terms in the choices do not accurately capture this specific reaction. Sinusitis refers to the inflammation of the sinuses, which can occur alongside or after allergic rhinitis but is not synonymous. Bronchitis concerns inflammation of the bronchial tubes in the lungs, while rhinorrhea describes the symptom of a runny nose without indicating the underlying allergic cause. Thus, allergic rhinitis is the precise term used for allergic reactions localized to the nasal cavities.
