Ontario Paramedic Practice Exam

What are typical respiratory presentations during an allergic reaction?

1. Decreased respiratory rate, Hypoventilation, Cyanosis

2. SOB, wheeze, cough, stridor

3. Apnea, Bradypnea, Hemoptysis

4. Tachypnea, Crackles, Pleuritic chest pain

The correct answer is: SOB, wheeze, cough, stridor

The correct answer highlights the typical respiratory presentations during an allergic reaction, which often include shortness of breath (SOB), wheezing, coughing, and stridor. These symptoms result from airway inflammation and constriction following exposure to an allergen. Shortness of breath is a common reaction as the body struggles to get enough air. Wheezing indicates narrowed airways usually due to bronchoconstriction, which can occur during an anaphylactic reaction. A cough is also often present as a reflex to clear the airways. Stridor, a high-pitched sound during inhalation, suggests significant airway obstruction and can be a critical sign indicating that immediate medical intervention is needed. While other presentations, such as decreased respiratory rate or cyanosis, may occur in different medical conditions, they are not typical for allergic reactions. This makes the selected presentation more specific for understanding and managing allergic responses effectively within the context of paramedic practice.
