EMT Airway Exam Guide 2025 With
Questions and Answers | Already
graded A+
intrapulmonary shunting - CORRECT ANSWER-bypassing of oxygen-poor blood past nonfunctional alveoli
to the left side of the heart
jaw-thrust maneuver - CORRECT ANSWER-technique to open the airway by placing the fingers behind
the angle of the jaw and bringing the jaw forward; used for patients who may have a cervical spine
injury.
,Labored breathing - CORRECT ANSWER-breathing that requires greater than normal effort; may be
slower or faster than normal and usually requires the use of accessory muscles
Larynx - CORRECT ANSWER-complex structure formed by many independent cartilaginous structures
that all work together; where the upper airway ends and the lower airway begins; also called the
voicebox
manually triggered ventilation device - CORRECT ANSWER-fixed flow rate ventilation device that delivers
a breath every time its button is pushed; also referred to as a flow-restricted, oxygen powered
ventilation device
mediastinum - CORRECT ANSWER-space within the chest that contains the heart, major blood vessels,
vagus nerve, trachea, major bronchi, and esophagus; located between the two lungs
metabolism/cellular respiration - CORRECT ANSWER-the biochemical process that result in production of
energy from nutrients within the cell
mid airway obstruction - CORRECT ANSWER-occurs when a foreign body partially obstructs the patient's
airway. The patient is able to move adequate amounts of air but also experiences some degree of
respiratory distress
minute volume - CORRECT ANSWER-volume of air moved through the lungs in 1 minute; calculated by
multiplying tidal volume and resp. rate; also called as minute ventialtion
nasal cannula - CORRECT ANSWER-oxygen delivery device in which oxygen flows through two small tube
like prongs that fit into the patient's nostrils; delivers 24% to 44% supplemental oxygen, depending on
, the flow rate.
nasopharyngeal nasal airway - CORRECT ANSWER-airway adjunct inserted into the nostril of an
unresponsive patient who is unable to maintain airway patency independently.
nasopharynx - CORRECT ANSWER-the nasal cavity; formed by the union of facial bones and protects the
respiratory tract from contaminants
nonrebreathing mask - CORRECT ANSWER-a combination mask and reservoir bag system that is the
preferred way to give oxygen in the prehospital setting; delivers up to 90% inspired oxygen and prevents
inhaling the exhaled gases (carbon dioxide)
Capnometry - CORRECT ANSWER-A device that measures the amount of expired CO2, capnometer
Carina - CORRECT ANSWER-point at which the trachea bifurcates into the left and right mainstem
bronchi
Chemoreceptors - CORRECT ANSWER-monitor the levels of O2, CO2, and the pH of the cerbrospinal fluid
and then provide feed back to the resp. centers to modify the rate and depth of breathing based on the
body's need
Aerobic Metabolism - CORRECT ANSWER-Metabolism that can proceed only in the presence of oxygen
