Treatment Step 3 for moderate persistent asthma involves which of the following?
High-dose inhaled corticosteroid
Medium-dose inhaled corticosteroid + montelukast
Medium-dose inhaled corticosteroid + long acting beta agonist
Medium-dose inhaled corticosteroid
Low-dose inhaled corticosteroid
Choose the incorrect statement.
Chest findings during routine clinic visits are often normal in children with asthma.
Diurnal variation of 15% in peak expiratory volume can be explained by asthma
FEV1/FVC ratio less than 0.80 is consistent with asthma
FEV1 decreases during or after exercise by >15% in an asthmatic person
Which of these is not found in patients with asthma?
Curschmann spirals
Charcot-Leyden crystals
Anitschkow cells
Anitschkow cells
Choose the correct statement regarding the pathogenesis of asthma.
The early-phase reaction is dominated by recruitment of leukocytes.
The late-phase reaction is dominated by bronchoconstriction, increased mucus production, vasodilation, and increased vascular permeability.
Atopic asthma is a classic example of type IV hypersensitivity reaction.
Leukotrienes C4, D4, E4 cause prolonged bronchoconstriction, increased vascular permeability, and increased mucus secretion.

Parainfluenza
Influenza
Rhinovirus
Virus responsible for bronchiolitis obliterans
Bocavirus
Adenovirus
RSV
Influenza
Prophylaxis given for bronchiolitis
Ribavarin
Zanamivir
Peramivir
Palivizumab
Which of the following is not true based from the 2021 AAP recommendations for bronchiolitis?
Diagnosis should be made clinically
Hypertonic saline can be used in the ER
Antibiotics is not recommended
Supplemental O2 for hypoxemia
The following are parameters for PICU admission in patients with bronchiolitis, except which:
Desaturation <95% despite 3L O2
Altered mental status
Apnea >20s with associated bradycardia
Requires suctioning more frequently
Which of the following best describes the law of LaPlace?
Alveolar pressure is inversely proportional with surface tension of alveoli.
Alveolar pressure is directly proportional with radius of alveoli.
Alveolar pressure of large alveoli greater than small alveoli if both surface tension is equal.
Alveolar pressure of large alveoli is lesser than small alveoli if both surface tension is equal.
Which of the following anatomy of the lung extends downward from the spinous process of the 7th cervical vertebra up to the 10th thoracic vertebra: and it lies about 1.5 in. (4 cm) from the midline?

Vesicular
Tracheal
Bronchial
Bronchovesicular
