Q41.
What is the most common age range for the development of extrinsic/allergic asthma?

a.

Birth to 2 years

b.

2 to 6 years

c.

6 to 12 years

d.

12 to 18 years

Discuss
Answer: (b).2 to 6 years Explanation:Extrinsic/allergic asthma is most commonly developed in early childhood, specifically between the ages of 2 to 6 years. This type of asthma is often linked to exposure to allergens such as dust, mites, smoke, and respiratory infections during this age range.
Q42.
What is the purpose of corticosteroids in asthma treatment?

a.

To reduce inflammation

b.

To increase inflammation

c.

To relax bronchospasm

d.

To promote mucus production

Discuss
Answer: (a).To reduce inflammation Explanation:Corticosteroids are anti-inflammatory drugs used in the treatment of asthma. They work by reducing inflammation in the airways, which can help to improve breathing and reduce symptoms such as wheezing, coughing, and shortness of breath. By reducing inflammation, corticosteroids can also help to prevent asthma attacks and minimize the need for rescue medications such as bronchodilators.
Q43.
Which test measures lung function in individuals with respiratory disorders?

a.

Complete Blood count

b.

Chest X-ray

c.

Spirometer or peak flow meter

d.

Echocardiogram

Discuss
Answer: (c).Spirometer or peak flow meter Explanation:Spirometer or peak flow meter is a lung or pulmonary function test that measures lung function in individuals with respiratory disorders, such as asthma. A spirometer measures the amount of air a person can inhale and exhale, while a peak flow meter measures how quickly a person can exhale. The other options listed, such as complete blood count, chest X-ray, and echocardiogram, do not measure lung function specifically.
Q44.
What is FEV1?

a.

The amount of air forcefully exhaled in one second

b.

The amount of air inhaled in one second

c.

The amount of air forcefully inhaled in one second

d.

The amount of air inhaled in one minute

Discuss
Answer: (a).The amount of air forcefully exhaled in one second Explanation:FEV1 is the maximal amount of air a person can forcefully exhale in one second.
Q45.
What is peak expiratory flow rate (PEFR)?

a.

The amount of air forcefully inhaled in one second

b.

The amount of air inhaled in one second

c.

The amount of air forcefully exhaled in one second

d.

The rate at which a person can exhale air

Discuss
Answer: (d).The rate at which a person can exhale air Explanation:The peak expiratory flow rate measures how fast a person can breathe out (exhale) air.
Q46.
Which classification of asthma has symptoms of cough, wheeze, chest tightness, or difficulty breathing less than 3-4 times a week?

a.

Mild intermittent asthma

b.

Mild persistent asthma

c.

Moderate persistent asthma

d.

Severe persistent asthma

Discuss
Answer: (a).Mild intermittent asthma Explanation:Mild intermittent asthma has symptoms less than 3-4 times a week.
Q47.
What is the lung function test used to measure the severity of asthma?

a.

Chest X-ray

b.

Complete Blood count

c.

Forced expiratory volume in 1 second (FEV1)

d.

Echocardiogram

Discuss
Answer: (c).Forced expiratory volume in 1 second (FEV1) Explanation:Forced expiratory volume in 1 second (FEV1) is used to measure lung function in individuals with asthma.
Q48.
What is the normal value of FEV1?

a.

Less than 40% of predicted value

b.

Between 40-60% of predicted value

c.

Between 60-80% of predicted value

d.

Greater than 80% of predicted value

Discuss
Answer: (d).Greater than 80% of predicted value Explanation:FEV1 of greater than 80% of predicted value is considered normal.
Q49.
What is the clinical classification of asthma based on?

a.

Frequency and severity of symptoms

b.

Age of the patient

c.

Race of the patient

d.

Gender of the patient

Discuss
Answer: (a).Frequency and severity of symptoms Explanation:The clinical classification of asthma is based on the frequency and severity of symptoms, such as cough, wheeze, chest tightness, or difficulty breathing, as well as the results of pulmonary function tests, including forced expiratory volume in 1 second (FEV1) and peak expiratory flow rate (PEFR). This helps healthcare professionals determine the appropriate treatment plan for the patient. Age, race, and gender may also be factors in asthma, but they are not the basis for clinical classification.
Q50.
What does the peak expiratory flow rate measure?

a.

How fast a person can inhale air

b.

How fast a person can exhale air

c.

How much air a person can inhale in one breath

d.

How much air a person can exhale in one breath

Discuss
Answer: (b).How fast a person can exhale air Explanation:The peak expiratory flow rate (PEFR) measures how fast a person can breathe out (exhale) air. It is a measure of the maximal speed of expiration during a forced exhalation, and is an important tool in monitoring and managing asthma.
