In the case of severe allergic reaction leading to respiratory failure, what treatment is essential?

• A. Administer antihistamines
• B. Provide inhaled corticosteroids
• C. Give epinephrine
• D. Initiate oxygen therapy

Answer: (C)

In the management of severe allergic reactions, particularly those that lead to respiratory failure, administering epinephrine is crucial. Epinephrine acts as a sympathomimetic agent that counteracts the effects of anaphylaxis by causing vasoconstriction, increasing heart rate, and bronchodilation. This not only helps to restore adequate circulation but also alleviates bronchospasms, thereby improving respiratory function. When a patient is experiencing anaphylaxis, the release of histamines and other mediators results in widespread vasodilation and bronchoconstriction, which can quickly lead to respiratory distress and cardiovascular compromise. Epinephrine is typically administered intramuscularly, and its rapid onset of action is vital in reversing these life-threatening symptoms. While other treatments like antihistamines, inhaled corticosteroids, and oxygen therapy may be part of an overall treatment plan, they do not provide the immediate life-saving effects that epinephrine does in acute situations. Antihistamines can help with allergic symptoms but do not address airway obstruction. Inhaled corticosteroids may take time to be effective, and oxygen therapy alone does not treat the underlying cause of anaphylaxis. Therefore, the administration of epinephrine is the essential, first-line
