Understanding Asthma: Causes, Symptoms, and Treatment

The video provides an in-depth look at asthma, a respiratory disorder affecting millions globally. It covers the symptoms, such as cough and wheezing, and explains the concept of bronchial hyperresponsiveness. The anatomy of the airways is discussed, highlighting the role of smooth muscle and cartilage in bronchospasms. Inflammation and mucus production are identified as key factors in asthma attacks. The video also explores various triggers, diagnostic methods like spirometry, and treatment options, including bronchodilators and corticosteroids. Practical advice for managing asthma is offered, emphasizing the importance of medication adherence.

What is the primary characteristic of asthma that makes the bronchial tree more responsive to stimuli?

• Bronchial hyperresponsiveness

• Bronchial rigidity

• Bronchial flexibility

• Bronchial hyporesponsiveness

Which of the following is a symptom of asthma?

• Continuous sneezing

• Persistent headache

• Constant fever

• Intermittent cough

What is the role of cartilaginous rings in the respiratory system?

• To keep the airway open

• To cause bronchospasm

• To produce mucus

• To increase airway flexibility

Which of the following is NOT a common trigger for asthma?

• Beta blockers

• Exercise

• High humidity

• Cold air

What is the purpose of spirometry in diagnosing asthma?

• To check heart rate

• To assess lung function

• To measure blood pressure

• To evaluate muscle strength

What is a common diagnostic test used to provoke a bronchospasm in suspected asthma patients?

• Mannitol inhalation

• Blood pressure test

• Heart rate monitoring

• Pulse oximetry

How do bronchodilators help in managing asthma symptoms?

• By reducing inflammation

• By increasing mucus production

• By relaxing smooth muscles

• By constricting airways

What is the function of inhaled corticosteroids in asthma treatment?

• To block beta receptors

• To stimulate mucus production

• To increase airway constriction

• To reduce airway inflammation

Which of the following is a combination inhaler used for asthma?

• Mannitol

• Aspirin

• Formoterol with budesonide

• Albuterol

What is a potential side effect of using oral corticosteroids for asthma?

• Reduced heart rate

• Decreased lung function

• Systemic side effects

• Increased mucus production
