Total questions: 10
Worksheet time: 5mins
Which anatomical feature makes pediatric airways more prone to obstruction?
Larger lung volumes
Smaller diameter of trachea and bronchi
Lower metabolic demand
Increased functional residual capacity (FRC)
Early clinical signs of respiratory distress in airway obstruction include:
Cyanosis and lethargy
Stridor and apnea
Tachypnea and nasal flaring
Hypotension
Which of the following is a hallmark sign of choanal atresia in newborns?
Relief of distress during crying
Barky cough
Drooling and dysphagia
Audible wheeze on expiration
The “4 Ds” (drooling, dysphagia, dyspnea, dysphonia) are characteristic of:
Croup
Epiglottitis
Bronchiolitis
Tracheomalacia
A lateral neck X-ray showing a “thumb sign” is diagnostic of:
Laryngomalacia
Epiglottitis
Croup
Foreign body aspiration
Which virus is the most common cause of laryngotracheobronchitis (croup)?
Influenza B
Adenovirus
Parainfluenza virus type 1
Respiratory syncytial virus (RSV)
Which treatment is most effective in rapidly reducing upper airway edema in croup?
Inhaled Heliox
Nebulized racemic epinephrine
Oral antibiotics
Chest physiotherapy
A prolonged expiratory phase is a cardinal sign of:
Upper airway obstruction
Lower airway obstruction
Epiglottitis
Bronchiectasis
Tracheomalacia is best described as:
Congenital overgrowth of airway smooth muscle
Dynamic collapse of the tracheal wall
Obstruction by excessive mucus
Bacterial infection of the trachea
