EMT P – Airway, Respiration, and
Ventilation | Verified Questions &
Answers | 100% Latest Update 2026
During respiration, as blood from the right side of the heart circulates
past the lungs, it drops off _____ and picks up _____? - CORRECT
ANSWER✔✔CO2 and oxygen.
You approach a woman lying supine on the street. She is unconscious,
but has a palpable carotid pulse of around 60 bpm. You note that her
entire mouth is full of vomit and she has ineffective respirations. How
should you proceed? - CORRECT ANSWER✔✔We are assessing this
patient with C-A-B. We know that there is a pulse of around 60 and that
allows us to move onto airway. Using a BVM would be skipping ahead
to breathing without first correcting her problem.
A 19-year-old male fell from the second story balcony of his college
residence. He is lying supine, unconscious, breathing is slow and
irregular, and is missing several teeth that appear to be in his mouth.
Your partner stabilizes the head and performs a jaw thrust. What
should you do next? - CORRECT ANSWER✔✔Suction his mouth to
remove the missing teeth. The first step of your assessment is to
ensure a patent airway. The first part of this was performing a jaw
thrust. It is then important to remove any possible obstructions that
could block the airway.
, The diaphragm contracts during? - CORRECT ANSWER✔✔Inspiration.
When the diaphragm contracts, it increases the volume of the thoracic
cavity. This draws air into the lungs, through the process known as
inspiration or inhalation
You are dispatched to a choking infant. How should you proceed when
you arrive on scene if the patient is still conscious? - CORRECT
ANSWER✔✔5 back blows and 5 chest thrusts. If the infant becomes
unconscious, carefully place them on the ground, open their mouth,
and look for the object. If an object is seen, remove it, then tilt the
head back to provide two rescue breaths. If you do not see adequate
chest rise, begin infant CPR.
When a person hyperventilates, their minute volume does what? -
CORRECT ANSWER✔✔Increases, due to an increased volume of air
moving through the respiratory tract. Minute volume simply refers to
the volume of air moving through the respiratory tract
What mechanisms causes emphysema? - CORRECT
ANSWER✔✔Destruction of the alveoli. Emphysema is caused by
smoking, which will destroy the alveoli.
What should your first action be when treating a conscious 40-year-old
male with rapid respirations? - CORRECT ANSWER✔✔Apply 100%
oxygen.
When a victim becomes unresponsive and is not breathing, what is the
most common cause of airway blockage? - CORRECT ANSWER✔✔The
tongue. The most common airway blockage is caused by the relaxing
of the throat muscles and the tongue falling back and blocking the
airway.
The body produces this chemical in order to keep atelectasis, or the
collapse of alveoli, from occurring: - CORRECT ANSWER✔✔Surfactant.
Surfactant decreases surface tension and helps to keep alveoli open
so respiration and gas exchange are possible.
