Which of the following types of asthma involves an acute asthma attack brought on by an upper respiratory infection?
A. Emotional
B. Extrinsic
C. Intrinsic
D. Mediated
Correct Answer: C. Intrinsic
Intrinsic asthma doesn’t have an easily identifiable allergen and can be triggered by the common cold. In intrinsic asthma, IgE is usually only involved locally, within the airway passages. Unlike extrinsic asthma, which is triggered by commonly known allergens, intrinsic asthma may be triggered by a wide range of non-allergy-related factors. Unlike people with extrinsic asthma, those with intrinsic asthma usually have a negative allergy skin test, so they often won’t benefit from allergy shots or allergy medications.
Option A: Asthma caused by emotional reasons is considered to be in the extrinsic category. Strong emotions and stress are well-known triggers of asthma. There is evidence of a link between asthma, anxiety, and depression, though the outcomes are sometimes not consistent. Anxiety and depression may be associated with poor asthma control.
Option B: Extrinsic asthma is caused by dust, molds, and pets; easily identifiable allergens. Extrinsic asthma is simply asthma caused by an allergic reaction, especially a chronic one. If the asthma is allergic, the client will have higher levels of IgE (Immunoglobulin E) present in the blood test.
Option D: Mediated asthma doesn’t exist. When airflow is obstructed as a result of exercise, it’s known as exercise-induced bronchoconstriction (EIB), which is a subcategory of asthma. EIB was previously known as exercise-induced asthma; however, exercise-induced asthma incorrectly implies that exercise is the underlying cause of asthma when it is actually its trigger, not the cause.
