The nurse would evaluate that the patient understands what triggers allergic rhinitis by which of the following patient responses?

Correct Answer: D

Rationale: Allergic rhinitis is a condition characterized by inflammation of the nasal passages caused by exposure to allergens. Common triggers include airborne pollens and molds, which are inhaled through the nose and can lead to symptoms such as sneezing, nasal congestion, and itchy/watery eyes. Understanding these triggers is essential for managing allergic rhinitis effectively, as patients can take steps to minimize their exposure to these allergens and reduce their symptoms. The correct answer is D because it specifically addresses the environmental triggers associated with allergic rhinitis.
