AIRT|VERIFIED QUESTIONS AND CORRECT DETAILED ANSWERS|RATED AND
GRADED A+ NEW UPDATE| 2026/2027
Snoring is likely caused by..... - ANSWER✔ The tongue falling back against the pharynx.
Blood travels into the lungs from the _____________. - ANSWER✔ Pulmonary Artery
The ONLY artery in the body that carries unoxygenated blood is...... - ANSWER✔ Pulmonary Artery
The Sellick maneuver performed by a third person will inhibit the flow of air into the stomach thus
reducing or eliminating ____________ - ANSWER✔ gastric distention
The irritant gas that primarily affects the upper airway is? - ANSWER✔ Partially water-soluble.
(Gases such as Ammonia, Sulfur dioxide, and Hydrogen chloride have chemical properties that readily
dissolve in the water covering the mucous membranes. This then allows them to produce an aqueous
solution.)
Inserting a nasal airway into a patient with a possible fracture to the skull could cause serious injury and
is ___________. - ANSWER✔ Contraindicated.
Pulmonary ventilation includes: - ANSWER✔ External respiration
Internal respiration
Cellular respiration
Metabolism.
As a person inhales, the diaphragm will _________ - ANSWER✔ Contract and create a negative
pressure drawing air into the lungs.
, Croup is an infection below the __________ and most often caused by a ________ virus - ANSWER✔
Vocal cords/Parainfluenza
Epiglottitis is most often caused by a bacterial infection of the ___________ - ANSWER✔ Epiglottis
and surrounding tissue.
(Patients may be drooling, anxious and cyanotic with shallow respirations. Inspiratory stridor may also
be heard. Epiglottitis can progress rapidly and result in airway occlusion and death if not treated
properly)
Belly breathing is normal for ___________ - ANSWER✔ Infants and young children
Accessory muscle use, retractions of the intercostals, and respirations of 15 breaths per minute, are
signs that __________ - ANSWER✔ A child is not breathing adequately
You and your partner Wanda arrive on scene to find a male patient complaining of dyspnea. The
caretaker attending the man verifies he has COPD and is currently on oxygen at 4 lpm by nasal canula.
Upon assessing respirations, you note the man is breathing at a rate of 30 breaths per minute and his
tidal volume is very shallow. What should you do? - ANSWER✔ Ventilate via BVM with attached O2 at
a tidal volume around 500 mL per breath.
(A patient who is only breathing with a tidal volume of 150 mL (very shallow) is ineffective at
oxygenating the tissues at any rate. The reason is that approximately 150 mL of air resides in the dead
space of the airway and never reaches the alveoli. If the patient is only taking in 150 mL, the oxygen is
never reaching the alveoli. This is conversely true with carbon dioxide being expelled from the lungs.)
The amount of air delivered to the lungs and airway in one breath. Is known as _________ -
ANSWER✔ Tidal Volume
The amount of air delivered to the lungs and airway over the course of a minute, is called __________. -
ANSWER✔ Minute Volume
