MECHANICAL VENTILATION CH37
2025 & 2026 COMPLETE QUESTIONS
AND CORRECT DETAILED ANSWERS
What is the primary role of respiratory therapists (RTs) in airway management? -
answerTo provide adequate ventilation and gas exchange by managing patients'
airways.
What are the three broad areas of airway care that RTs must be proficient in? -
answerAirway clearance techniques, insertion and maintenance of artificial airways, and
assisting in special procedures.
What are the two techniques for endotracheal suctioning? - answerOpen technique
(disconnecting from the ventilator) and closed technique (using an in-line suction
catheter).
What is the purpose of suctioning in airway management? - answerTo remove retained
secretions or fluids from the airways to prevent obstruction.
What complications can arise from retained secretions in the airway? -
answerHypoxemia, hypercapnia, atelectasis, and infection.
What is the difference between deep suctioning and shallow suctioning? - answerDeep
suctioning involves inserting the catheter until resistance is met, while shallow
suctioning involves advancing to a predetermined depth.
What is the indication for performing endotracheal suctioning? - answerClinical
indicators such as coarse crackles (rhonchi) heard on auscultation, rather than a preset
schedule.
What equipment is needed for suctioning? - answerVacuum source, calibrated
regulator, collection bottle, sterile suction catheter, gloves, and oxygen source.
What are artificial airways used for? - answerTo support patients whose natural airways
are inadequate.
What is a tracheostomy? - answerA surgical procedure to create an opening in the
trachea to facilitate breathing.
What is the purpose of cuff care in airway management? - answerTo ensure proper
inflation and prevent airway leaks or damage to the trachea.
,What is extubation? - answerThe process of removing an endotracheal tube from a
patient.
What is the role of humidification in airway management? - answerTo ensure adequate
moisture in the air delivered to the patient, preventing airway irritation.
What is a laryngectomy? - answerSurgical removal of the larynx, often requiring
alternative airway management.
What is tracheomalacia? - answerA condition characterized by the weakening of the
tracheal wall, leading to airway collapse.
What is the significance of assessing patient readiness for extubation? - answerTo
determine if the patient can breathe independently without mechanical support.
What is a tracheoinnominate artery fistula? - answerA serious complication where a
tracheostomy tube erodes into the innominate artery.
What are the signs of airway obstruction? - answerRetained secretions, foreign bodies,
or structural changes like edema or tumors.
What is the purpose of sputum sampling? - answerTo obtain samples for diagnostic
testing of respiratory conditions.
What is the role of bronchoscopy in airway management? - answerTo remove foreign
bodies or secretions beyond the mainstem bronchi.
What is the importance of minimizing nosocomial infections in airway management? -
answerTo prevent hospital-acquired infections that can complicate patient recovery.
What is a fenestrated tracheostomy tube? - answerA tube with openings that allow
airflow through the larynx, facilitating speech.
What is the purpose of measuring tracheal tube cuff pressures? - answerTo ensure
proper cuff inflation and prevent tracheal injury.
What is the recommended suctioning technique for infants and children? -
answerShallow suctioning is preferred for routine suctioning.
What are the risks associated with deep suctioning? - answerAirway trauma, alterations
in heart rate, and blood pressure changes.
What is the purpose of providing for patient communication in airway management? -
answerTo ensure patients can express their needs and discomfort during airway
interventions.
, What is a tracheoesophageal fistula? - answerAn abnormal connection between the
trachea and esophagus, complicating airway management.
What is the significance of assessing and confirming proper endotracheal tube
placement? - answerTo ensure effective ventilation and prevent complications.
What condition does the patient in the scenario have? - answerAmyotrophic lateral
sclerosis (ALS)
What procedure was performed to aid secretion clearance? - answerTracheostomy tube
placement
What abnormal breath sounds were noted in the left lung? - answerCoarse crackles
What was observed in the right lung during the assessment? - answerAbsent breath
sounds
What does complete opacification of the right hemithorax on a chest x-ray suggest? -
answerPossible mucus plug in the mainstem bronchus
What is the recommended suction pressure for adults? - answerLess than 200 mm Hg
What is the recommended suction pressure for neonates and pediatric patients? -
answerLess than 120 mm Hg
What does coarse crackles indicate? - answerAirflow through retained secretions
What should be done if no clinical improvement is seen after suctioning? -
answerSuggest a flexible bronchoscopy to remove secretions
What is the rule of thumb for suction catheter size in adults? - answerShould occlude
less than 50% of the internal diameter of the tracheal tube
What is the rule of thumb for suction catheter size in neonates? - answerShould occlude
less than 70% of the tracheal tube
What is a potential consequence of using a catheter that is too large? -
answerObstruction of part or all of the airway
What is the purpose of an in-line suction catheter? - answerTo reduce physiological
disturbances and maintain oxygenation
What is a key advantage of using in-line suction catheters? - answerLess likely to cause
cross-contamination
