Final answer:
Swallowing difficulty is an indicator of an anaphylactic reaction following a bee sting and should be treated immediately with epinephrine. Bradycardia is less characteristic of anaphylaxis, as this condition usually involves tachycardia due to low blood pressure.
Step-by-step explanation:
When a health care professional is assessing a patient following a bee sting, certain findings can indicate an anaphylactic reaction. Anaphylaxis is a rapid, systemic allergic reaction that can cause life-threatening symptoms if not treated promptly. Among these symptoms, swallowing difficulty (or swelling of the tongue and throat) certainly points to a potential anaphylactic reaction, as it can cause severe swelling that might obstruct the airway.
Although bradycardia, which is a slower than normal heart rate, can sometimes be associated with anaphylaxis, it is not the most characteristic sign. The typical cardiac manifestation in anaphylaxis is an increase in heart rate (tachycardia) due to a drop in blood pressure. Therefore, swallowing difficulty is a clear indicator of an anaphylactic reaction and immediate treatment with epinephrine should be administered to counteract the reaction.
