The two most frequent levels of obstruction during sleep in children with hypertrophied tonsils are:
Soft palate and base of the tongue
Base of the tongue and hard palate
Base of the tongue and hyoid bone
Hyoid bone and tip of epiglottis
None
True in events leading to cor pulmonale, EXCEPT:
Longstanding hypoxemia and hypercarbia
Left-sided heart failure
Increased airway resistance
Pulmonary artery hypertension
Pulmonary venule constriction
A thorough history-taking and physical examination is the basis for pre-operative evaluation for pediatric patients who will undergo ENT surgeries. The following may be present, EXCEPT:
Sleep-disordered breathing
Elongated face
Prognathic mandible
Retrognathic mandible
High-arched palate
Component of STOP-BANG questionnaire:
Sneezing
Tremors
Observation of restlessness during sleep
Elevations in blood pressure
Nighttime somnolence
Component of STBUR questionnaire:
Snorting
Sneezing
Tremors
Trouble concentrating in daytime activities
Unrefreshed feeling after sleeping
Which of the following is TRUE:
The long-term effects of OSAS are NOT limited to the airway
Increased body mass index and obesity may lead to increased cognitive vulnerability
Increased frequency of hyperactivity and increased levels of C-reactive protein
None of the above
All of the above
True about acute post-tonsillectomy pulmonary edema:
Proposed mechanism is that during inspiration before adenotonsillectomy, the positive intrapleural pressure that is generated causes a decrease in venous return, diminishing pulmonary blood volume
Pleural pressure in the healthy child with airway obstruction ranges from -2.5 cm to -10 cm H2O during inspiration
Intrapleural pressure in the healthy child without airway obstruction can be as much as -30 cm H2O during inspiration
The rapid relief of airway obstruction results in decreased airway pressure, an increase in venous return, an increase in pulmonary hydrostatic pressure, hyperemia, and finally pulmonary edema
None of the above
The most common cause of stridor in infants:
Cysts
Tracheomalacia
Laryngomalacia
Choanal atresia
Croup
Patients with a history of head and neck cancer may have undergone prior chemotherapy, which can affect specific organ systems, or radiation, which can lead to one of the following, rendering direct laryngoscopy difficult:
Anatomic nasal obstruction reduce oropharyngeal cross-sectional area
Fibrosis and ankylosis in the temporomandibular joint
Anatomic imbalance between the upper airway soft tissue volume and craniofacial size
Pharyngeal dilator muscles do not contract maximally
All of the above
Systemic absorption of vasoconstrictive agents during functional endoscopic sinus surgery may cause:
Hypertension
Bradycardia
Tachycardia
Arrythmias
All of the above
