Respiratory Therapy Exam Questions With
Accurate Answers 2025\2026 A+ Grade.
Induced sputum sample medication
- accurate answer-Best medication for induction is 10% Hypertonic Saline
Solution.
Racemic Epinephrine category
- accurate answer-Belongs to the category of Bronchodilator.
Normal cough reflex phases
- accurate answer-Includes Irritation, Inspiration, Expiration, and Expulsion.
BTPS conditions point
- accurate answer-The point in the respiratory tract where inspired gas
reaches temperature, ambient pressure, saturated conditions is the
Isothermic Saturation Boundary.
Short-acting catecholamines for swelling
- accurate answer-Racemic epinephrine is used for its strong alpha-1-
vasoconstricting effects to reduce swelling in the nose and larynx.
Endotracheal Tube suctioning time
- accurate answer-Should take less than 15 seconds.
Cough phases affected by neuromuscular disorder
- accurate answer-Primarily affects the Compression and Expulsion phases.
Impairment of mucociliary clearance
- accurate answer-Impairment can occur due to inadequate humidification,
high inspired O2 concentrations, and tracheobronchial suctioning.
Mucomyst dilution for 3 ml
- accurate answer-Add 1.5 ml of 20% Mucomyst to 1.5 ml of diluent.
Normal suctioning pressure range
- accurate answer-The normal range of negative pressure for suctioning an
adult patient trachea is -80 to -100 mmHg.
,Max size suction catheter for 7.5 mm ETT
- accurate answer-The max size suction catheter to use is 14 Fr.
Chronic sputum production conditions
- accurate answer-Conditions associated include Bronchiectasis and Cystic
Fibrosis.
Sputum production for airway clearance therapy
- accurate answer-Need to observe greater than 25 ml/day to recommend
airway clearance therapy.
Non-essential laboratory data for airway clearance
- accurate answer-Chest radiograph is NOT essential in assessing a patient's
need for airway clearance therapy.
Inhalation of dry gases effects
- accurate answer-Can increase viscosity of secretions, impair mucociliary
motility, and increase airway irritability.
Largest group of aerosolized drugs
- accurate answer-Adrenergic bronchodilators comprise the largest single
group of drugs among aerosolized agents used for inhalation.
Clinical indications for cool humidified gas
- accurate answer-Include Post extubation edema, Upper airway
inflammation, and Croup.
Absolute contraindications for postural drainage
- accurate answer-Include Patient with unstabilized head and neck injury and
Patient with active hemorrhage.
Factors affecting humidifier performance
- accurate answer-Factors include temperature, surface area, and contact
time.

- accurate answer-Greater than 25 ml/day
, Laboratory data NOT essential for airway clearance therapy
- accurate answer-Electrolyte results

- accurate answer-Adrenergic bronchodilators
Clinical indications for cool humidified gas EXCEPT
- accurate answer-Rhonchi
Purpose of pilot balloon on ETT and Tracheostomy Tubes
- accurate answer-to monitor cuff status and pressure
Purpose of Murphy eye on endotracheal tubes
- accurate answer-Ensure gas flow if main port is blocked
Recommended action after minor bleeding from suctioning
- accurate answer-Discontinue nasotracheal suctioning for 48 hrs and
reassess
Standard size of ETT or Trach Tube adapters
- accurate answer-15 mm external diameter
Duration of action for DuoNeb
- accurate answer-6 hours
Procedure of choice for patent tracheal airway in emergency
- accurate answer-Orotracheal intubation
Side effects of beta-2-selective bronchodilators
- accurate answer-Not specified in the notes.
Tremor
- accurate answer-An involuntary, rhythmic muscle contraction leading to
shaking movements in one or more parts of the body.
Headache
- accurate answer-Pain or discomfort in the head, scalp, or neck.
