Question 1

Recurrent respiratory papillomatosis is the most Common benign neoplasm of which airway structure

Accepted Answer

Recurrent respiratory papillomatosis is the most common benign neoplasm of the larynx, specifically the vocal cords and subglottis.

Question 2

Which of the following is both the most Common laryngeal anomaly and the most Common Congenital cause of stridor

Accepted Answer

Laryngomalacia is the most common laryngeal anomaly and the most common congenital cause of stridor. Epiglottitis is an acute infection of the epiglottis and is not a congenital anomaly. Cleft palate is a congenital anomaly but does not typically cause stridor. Glossoptosis is the posterior displacement or retraction of the tongue and can cause airway obstruction, but it is not as common as laryngomalacia.

Question 3

What Common disease process acCompanies laryngomalacia

Accepted Answer

Gastroesophageal reflux commonly accompanies laryngomalacia, as the weak cartilage in the larynx can allow refluxed stomach contents to enter the airway, leading to irritation and inflammation. Other choices may also occur, but reflux is the most commonly associated.

Question 4

What initial intervention for Robin sequence will alleviate 70% of an infant's airway obstruction

Accepted Answer

Placing an infant with Robin sequence in the prone position can alleviate up to 70% of the airway obstruction by allowing the tongue to fall forward, thus improving airway patency.

Question 5

All of the following are symptoms of severe laryngomalacia except:

Accepted Answer

Laryngomalacia is a condition where the soft, immature cartilage of the upper larynx collapses inward during inhalation, causing airway obstruction. Symptoms of severe laryngomalacia can include cyanosis (a bluish discoloration of the skin due to lack of oxygen), feeding difficulties, failure to thrive, and in very severe cases, cor pulmonale (right-sided heart failure from long-standing pulmonary hypertension). Therefore, none of the options listed are exceptions; they can all be symptoms of severe laryngomalacia.

Question 6

Treatment and management of choanal atresia include which of the following options
I.Choanal opening created via surgical repair
II.Propping infant's nose open with nasal trumpet
III.Intubation
IV.Using a feeding nipple with a large opening

Accepted Answer

The best choices for treatment and management of choanal atresia are options I, III, and IV. Surgical repair is necessary to create a choanal opening, intubation may be needed to maintain an airway, and using a feeding nipple with a large opening allows for adequate feeding. Propping the infant's nose open with a nasal trumpet may cause irritation and is not typically used for management.

Question 7

Patency of the tracheostomy tube should be verified by which of the following procedures
I.Positive end-tidal CO₂
II.Measuring exhaled tidal volume
III.Passing a suction catheter
IV.Bag-mask ventilation

Accepted Answer

Positive end-tidal CO₂ (I) can be used to confirm that air is passing through the tracheostomy tube and being exhaled. Passing a suction catheter (III) can also assess for any obstructions or secretions in the tube. Measuring exhaled tidal volume (II) and bag-mask ventilation (IV) are not direct methods of verifying tracheostomy tube patency.

Question 8

For what subglottic airway Condition is intubation not a form of treatment unless respiratory distress is severe

Accepted Answer

Croup is typically managed with steroids and nebulized epinephrine. Intubation is reserved for severe cases with significant respiratory distress, as it can further irritate and inflame the airway.

Question 9

Which of the following tests can definitively verify the presence of recurrent respiratory papillomatosis

Accepted Answer

Endoscopy is the best choice as it allows visualization of the papillomas in the respiratory tract, confirming the presence of recurrent respiratory papillomatosis. Sputum culture and blood cultures are used to identify bacterial or fungal infections, which may be secondary complications of papillomatosis. Lateral neck radiographs and complete metabolic panels are not specific tests for papillomatosis.

Question 10

What organism causes exudative tracheitis

Accepted Answer

Staphylococcus aureus is the organism that causes exudative tracheitis, a condition characterized by the formation of a thick, adherent membrane lining the trachea, which can lead to airway obstruction.

Question 11

What organism causes the viral disease recurrent respiratory papillomatosis

Accepted Answer

Recurrent respiratory papillomatosis is caused by infection with the human papillomavirus (HPV), specifically types 6 and 11.

Question 12

The supraglottis Consists of all of the following portions of the larynx except:

Accepted Answer

The supraglottis consists of the epiglottis, false vocal cords, arytenoids, and aryepliglottic fold. The hard palate is not part of the larynx, therefore it is not part of the supraglottis.

Question 13

Which of the following respiratory supports should be given to a patient with a nonanatomical nasopharyngeal obstruction
I.Supplemental oxygen when SpO₂ is less than 92%
II.Nasal suctioning
III.Nasal stents
IV.Repositioning airway
V.Nasal prongs
VI.Noninvasive nasal mask

Accepted Answer

The answer of Which of the following respiratory supports should...

Question 14

Which of the following are examples of Conditions that would require a tracheostomy
I.Subglottic stenosis
II.Croup
III.Robin sequence
IV.Bronchopulmonary dysplasia

Accepted Answer

Subglottic stenosis and Robin sequence are conditions that can necessitate a tracheostomy due to airway obstruction or difficulty. Bronchopulmonary dysplasia, a chronic lung condition, may also require a tracheostomy for long-term ventilation support. Croup, however, is typically managed with other treatments and rarely requires a tracheostomy.

Question 15

Which of the following are Considered inexpensive methods to identify choanal atresia
I.Tissue test
II.Mirror test
III.Nasal endosCopy
IV.Deep tracheal suctioning
V.MRI scan
VI.CT scan

Accepted Answer

The tissue test and mirror test are simple, low-cost methods that can be performed in a clinical setting to suggest the presence of choanal atresia by checking for airflow obstruction. Nasal endoscopy, while more invasive, is still relatively inexpensive compared to imaging techniques like MRI and CT scans, and deep tracheal suctioning is a procedure that does not require expensive equipment.

Question 16

Tracheoesophageal fistula should be suspected when an infant presents with which of the following symptoms
I.Excessive drooling
II.Feedings that give way to respiratory distress
III.Absence of stridor or barking Cough
IV.Accepting orogastric tube into stomach without incidence

Accepted Answer

Tracheoesophageal fistula can cause excessive drooling and feedings that give way to respiratory distress. The absence of stridor or barking cough is also a common feature. Accepting orogastric tube into the stomach without incident can be present in both normal infants and those with tracheoesophageal fistula. Therefore, the best choice is B, which includes the first two symptoms as key features of tracheoesophageal fistula.

Question 17

What is Considered the most Common subglottic abnormality seen by registered respiratory therapists

Accepted Answer

Subglottic stenosis is considered the most common subglottic abnormality seen by registered respiratory therapists. It is a narrowing of the trachea just below the vocal cords, which can result in breathing difficulties. Stridor, vocal fold nodules, and gastroesophageal reflux can also cause subglottic abnormalities, but they are not as commonly seen as subglottic stenosis.

Question 18

What is the treatment for macroglossia

Accepted Answer

Tongue reduction surgery is the most effective treatment for macroglossia, as it involves reducing the size of the enlarged tongue. Tonsillectomy, IV antibiotics, and incision and drainage are not effective treatments for macroglossia.

Question 19

What method of emergency tracheostomy management utilizes the Seldinger technique

Accepted Answer

The Seldinger technique involves threading a new tracheostomy tube over a small suction catheter, which is inserted into the stoma to locate the pathway to the trachea. This is a commonly used method for emergency tracheostomy management. Choices A, B, and C are not associated with the Seldinger technique.

Question 20

Management of subglottic hemangiomas includes all of the following except:

Accepted Answer

The management of subglottic hemangiomas includes tracheostomy, steroids, and surgical intervention, but the most effective treatment is propranolol, which was not listed in the options. Therefore, the correct answer is C.
