Epinephrine is indicated for which of the following conditions?

• A. Hypotension
• B. Dehydration
• C. Severe bronchoconstriction from asthma and COPD
• D. Hyperglycemia

Answer: (C)

Epinephrine helps by opening the airways and tightening surrounding blood vessels, which is why it’s used for severe bronchoconstriction. Its action on beta-2 receptors relaxes bronchial smooth muscle, rapidly improving airflow in asthma or COPD flare-ups, and its alpha-adrenergic effect reduces airway swelling to further ease breathing. The other conditions listed aren’t treated with epinephrine as a primary indication—dehydration is addressed with fluids, hyperglycemia with glucose control, and hypotension alone isn’t treated with epinephrine unless it’s part of anaphylaxis where it helps raise blood pressure. So the best choice is the option describing severe bronchoconstriction from asthma and COPD.
