Which of the following is NOT a treatment for an asthma attack?

During an asthma attack, the primary goal is to open the airways and improve breathing. Treatments such as an inhaler and epinephrine are effective as they help to relieve bronchoconstriction and decrease inflammation, thereby allowing for easier airflow.

An inhaler, typically containing bronchodilators like albuterol, provides quick relief of asthma symptoms by relaxing the muscles around the airways. Epinephrine, often used in severe cases, can also open airways and reduce severe allergic reactions that may accompany an asthma attack.

In contrast, insulin is not related to the treatment of asthma. It is primarily used for managing blood sugar levels in individuals with diabetes. Thus, it does not address the respiratory issues presented during an asthma attack and is therefore not a treatment for that condition.
