Question

Quizplus · Accepted Answer

The patient's symptoms are indicative of an allergic reaction, specifically to the pollen from the flowers in the bouquet. Antihistamines are a common treatment for allergies as they block the effects of histamines, which are released during an allergic reaction and cause symptoms such as itching, sneezing, and watery eyes. Options A, B, and E are not relevant to the treatment of allergies, and option C (sterile pollen) is not a practical solution as it would require eliminating all potential sources of pollen exposure.
