Which medication is most commonly used as a first-line controller in pediatric asthma management?
Long-acting beta agonists
Inhaled corticosteroids
Leukotriene receptor antagonists
Oral corticosteroids
Inhaled corticosteroids are the cornerstone for long-term management of pediatric asthma. They decrease airway inflammation and reduce the frequency of exacerbations, making them the preferred first-line therapy.
Which test is considered the gold standard for diagnosing cystic fibrosis in pediatric patients?
Genetic testing
Chest X-ray
Bronchoscopy
Sweat chloride test
The sweat chloride test remains the gold standard for diagnosing cystic fibrosis as it measures the elevated chloride levels in sweat characteristic of the disorder. Its reliability and simplicity make it the most widely used diagnostic tool in pediatric patients.
Which pulmonary function test parameter is a key indicator of airway obstruction in children?
FEV1
Forced Vital Capacity (FVC)
Residual Volume (RV)
Total Lung Capacity (TLC)
FEV1, or forced expiratory volume in one second, is a critical measure to evaluate the presence and severity of airway obstruction in children. It offers essential insights into lung function, particularly in conditions like asthma.
What is the diagnostic gold standard to confirm obstructive sleep apnea in children?
Polysomnography
Pulse oximetry
Home sleep apnea test
Sleep diary
Polysomnography is a comprehensive sleep study that monitors multiple physiological parameters during sleep. It is considered the diagnostic gold standard for confirming obstructive sleep apnea in children.
How do inhaled bronchodilators alleviate acute asthma symptoms in children?
They directly reduce inflammation in the airways
They act as long-term control medications
They relax bronchial smooth muscle to relieve bronchospasm
They decrease mucus production
Inhaled bronchodilators work by relaxing the bronchial smooth muscle, which reduces the bronchospasm associated with an acute asthma attack. Their quick onset of action makes them essential for the rapid relief of symptoms in children.
Which pulmonary function parameter is most sensitive to early small airway obstruction in pediatric patients?
Total Lung Capacity (TLC)
Forced Vital Capacity (FVC)
Forced Expiratory Flow 25-75% (FEF25-75)
Forced Expiratory Volume in 1 second (FEV1)
FEF25-75 is sensitive to changes in the small airways and can detect early signs of obstruction before notable declines in FEV1 occur. This makes it a valuable parameter in assessing early airway dysfunction in pediatric patients.
Which hormone plays the primary role in regulating circadian rhythms and is used in managing pediatric insomnia?
Melatonin
Cortisol
Dopamine
Serotonin
Melatonin is the hormone responsible for regulating the sleep-wake cycle, making it essential in establishing circadian rhythms. Its use in managing pediatric insomnia is based on its ability to signal the body to prepare for sleep.
What is a potential complication of long-term systemic corticosteroid use in children with severe asthma?
Cardiac arrhythmia
Hyperthyroidism
Renal dysfunction
Growth suppression
Long-term use of systemic corticosteroids in children can interfere with normal growth, leading to growth suppression. This is a well-documented side effect and poses significant concerns in pediatric management of severe asthma.
During polysomnography, which index is used to assess the severity of obstructive sleep apnea in pediatric patients?
Respiratory Disturbance Index
Sleep Efficiency
Oxygen Desaturation Index
Apnea-Hypopnea Index (AHI)
The Apnea-Hypopnea Index (AHI) quantifies the number of apneas and hypopneas per hour of sleep, serving as a standard metric for determining the severity of obstructive sleep apnea. A higher AHI correlates with more severe disease, guiding intervention strategies.
Which test is most effective for diagnosing exercise-induced bronchoconstriction in a pediatric patient?
Peak flow monitoring at rest
Methacholine challenge test
Bronchodilator reversibility test
Exercise challenge test
The exercise challenge test specifically provokes bronchoconstriction under controlled physical exertion, making it the test of choice for diagnosing exercise-induced bronchoconstriction in children. It helps distinguish exercise-related symptoms from other respiratory issues.
Which genetic mutation is most commonly associated with cystic fibrosis in children?
Î"F508 mutation in the CFTR gene
Mutation in the ABCA3 gene
Mutation in the SFTPB gene
Mutation in the TGF-β gene
The Î"F508 mutation in the CFTR gene is the most prevalent mutation causing cystic fibrosis, leading to dysfunctional chloride transport and thick secretions. Its identification is crucial for accurate diagnosis and subsequent management of the disease in pediatric patients.
Which imaging modality provides the best dynamic evaluation for suspected airway malacia in pediatric patients?
Dynamic CT scan
Ultrasound
MRI
Standard chest X-ray
A dynamic CT scan, particularly with expiratory phase imaging, allows for real-time visualization of airway collapse. This makes it the preferred modality for evaluating airway malacia, as it provides detailed anatomical insights not available on a standard chest X-ray.
Which of the following factors is least likely to contribute to sleep-disordered breathing in children?
Allergic rhinitis
Obesity
High levels of physical activity
Adenotonsillar hypertrophy
High levels of physical activity are generally associated with improved respiratory and overall health, rather than contributing to airway obstruction. In contrast, adenotonsillar hypertrophy, obesity, and allergic rhinitis are recognized risk factors for sleep-disordered breathing in children.
During an acute asthma exacerbation, which physiological change is typically observed in pediatric patients?
Reduced pulmonary blood flow
Decreased mucus production
Enhanced alveolar ventilation
Increased airway resistance
Acute asthma exacerbations are characterized by increased airway resistance due to bronchoconstriction and inflammation. This physiological change directly leads to the reduced airflow and breathing difficulties experienced during an asthma attack.
