Final answer:
The initial treatment for bronchospasm due to anaphylaxis is Epinephrine IV. This medication quickly raises blood pressure and relaxes bronchial smooth muscles to alleviate life-threatening symptoms.
Step-by-step explanation:
The initial treatment for bronchospasm associated with anaphylaxis includes Epinephrine IV (C). Anaphylaxis is a severe allergic reaction that can be life-threatening and involves symptoms like respiratory distress and a significant drop in blood pressure. The drug epinephrine is used as an emergency treatment because it can quickly counteract these symptoms by raising blood pressure and relaxing the bronchial smooth muscles, making it easier for the patient to breathe. In cases where individuals are at known risk for severe allergies, they are often advised to carry an automatic epinephrine injector, such as an EpiPen®, which can be used to administer a dose of the medication in the event of exposure to an allergen, buying time until medical help can be sought.
