What type of disease is asthma?

Back

Obstructive lung disease

Answer explanation

Asthma is classified as an obstructive lung disease because it causes narrowing of the airways, leading to difficulty in breathing. This is distinct from restrictive lung diseases, which involve reduced lung volume.

Front

Fill in the blank: Asthma is an obstructive lung disease, second to obstruction from conditions in the ______ of the lumen.

Back

wall

Answer explanation

Asthma causes obstruction primarily due to inflammation and constriction of the airway walls. Therefore, the correct term to fill in the blank is 'wall', as it refers to the structural components affecting the lumen.

Front

Refer to the diagram. Which of the following is a feature of the airway in asthma compared to normal? Thinner mucous glands, Narrowed lumen, Decreased mucous glands, Reduced smooth muscle

Back

Narrowed lumen

Answer explanation

In asthma, the airway is characterized by a narrowed lumen due to inflammation and bronchoconstriction, which restricts airflow. This contrasts with normal airways, which have a wider lumen.

Front

What are most cases of asthma triggered by?

Back

Allergens and stimuli such as exercise or exposure to cold air

Answer explanation

Most cases of asthma are triggered by allergens and stimuli, such as exercise or exposure to cold air, which can provoke an asthma attack. Bacteria, viruses, and fungi are less common triggers.

Front

Is airway obstruction in asthma usually reversible?

Back

True

Answer explanation

Airway obstruction in asthma is usually reversible due to the nature of asthma attacks, which can be alleviated with bronchodilators and other treatments. Therefore, the correct answer is True.

Front

Asthma can be classified into ______ (Allergic) and ______ (Nonallergic) types: Extrinsic (Allergic) and Intrinsic (Nonallergic), Intrinsic (Allergic) and Extrinsic (Nonallergic), Obstructive (Allergic) and Restrictive (Nonallergic), Primary (Allergic) and Secondary (Nonallergic).

Back

Extrinsic (Allergic) and Intrinsic (Nonallergic)

Answer explanation

Asthma is classified into Extrinsic (Allergic) and Intrinsic (Nonallergic) types. Extrinsic asthma is triggered by allergens, while Intrinsic asthma is not related to allergens, making the first option the correct choice.

Front

The release of inflammatory chemicals in asthma leads to mucosal edema.

Back

True

Answer explanation

True. In asthma, the release of inflammatory chemicals causes mucosal edema, leading to airway obstruction and difficulty in breathing.

Front

Which type of asthma is more common and associated with the release of Immunoglobulin E (IgE)? Options: Intrinsic Factors (Nonallergic Asthma), Extrinsic Factors (Allergic Asthma), Both, Neither

Back

Extrinsic Factors (Allergic Asthma)

Answer explanation

Extrinsic Factors (Allergic Asthma) is more common and linked to the release of Immunoglobulin E (IgE), which plays a key role in allergic reactions and asthma exacerbations.

Front

Intrinsic Factors (Nonallergic Asthma) is characterized by which of the following? A) History of allergies, B) No history of allergies, C) Develops in childhood, D) Treatments are always effective

Back

No history of allergies

Answer explanation

Intrinsic factors in nonallergic asthma are defined by the absence of a history of allergies, distinguishing them from allergic asthma. Therefore, the correct answer is B) No history of allergies.

Front

Fill in the blank: Intrinsic Factors (Nonallergic Asthma) usually develops in _________.

Back

middle age

Answer explanation

Intrinsic Factors (Nonallergic Asthma) typically develop in middle age, as this is when individuals are more likely to experience triggers related to stress, exercise, and respiratory infections, distinguishing it from childhood or adolescence onset.
