Emergency Medical Technician (EMT) Intermediate Practice Exam

Why should an AEMT transport a patient with an allergic reaction who has used epinephrine?

1. The patient's symptoms could recur up to 8 hours later

2. The patient may need further observation

3. The patient could have an anaphylactic reaction again

4. All of the above

The correct answer is: The patient's symptoms could recur up to 8 hours later

Transporting a patient with an allergic reaction who has used epinephrine is crucial for several reasons, particularly the possibility of symptoms returning. Epinephrine can provide immediate relief by causing vasoconstriction and bronchodilation, but its effects can wear off after a period of time, especially in the context of a severe allergic reaction such as anaphylaxis. The potential for symptoms to recur within a certain time frame is significant; in fact, it is well-documented that symptoms of anaphylaxis can reappear hours after initial exposure, meaning the patient continues to be at risk even after receiving epinephrine. Immediate medical evaluation and monitoring are essential to manage any resurgence of symptoms. Additionally, further observation is important as other interventions may be necessary depending on the patient's condition following epinephrine administration. Monitoring vital signs, assessing respiratory function, and being prepared for subsequent treatments are all critical components of post-epinephrine care. Moreover, the risk of a second anaphylactic reaction, known as biphasic anaphylaxis, underscores the need for transport. This occurrence is not uncommon and can happen without re-exposure to the allergen. Taken together, the correct answer reflects the comprehensive need for patient transport following an allergic
