Question

A 32-year-old man who was stung by a bee has diffuse hives, facial swelling, and difficulty breathing. When he breathes, you hear audible stridor. What does this indicate?

a) Upper airway obstruction
b) Lower airway obstruction
c) Pulmonary edema
d) Anaphylaxis

Answer 1

The symptoms of diffuse hives, facial swelling, difficulty breathing, and audible stridor in a 32-year-old man indicate he is likely experiencing anaphylaxis, which is a severe allergic reaction and can cause upper airway obstruction, requiring immediate medical attention and treatment with epinephrine.

Step-by-step explanation:

The 32-year-old man demonstrating symptoms of diffuse hives, facial swelling, difficulty breathing, and audible stridor is likely experiencing an anaphylactic reaction. Stridor is a high-pitched, wheezing sound caused by disrupted airflow and is commonly associated with upper airway obstruction which can be a presenting symptom of anaphylaxis. Anaphylaxis is a severe, life-threatening allergic reaction characterized by systemic signs such as swelling of the throat, severe drop in blood pressure, and potential airway obstruction. These symptoms rapidly develop and require immediate medical attention, often managed with the administration of epinephrine which is found in devices such as an EpiPen® to quickly address severe allergic responses and maintain open airways.
