EMT AIRWAY FISDAP EXAM 2025
QUESTIONS AND ANSWERS
Which of the following would cause an increase in the amount of exhaled carbon dioxide? -
ANS Increased cardiac output
All of the following are signs of hypoxia except - ANS dehydration
Inhalation occurs when the - ANS diaphragm and intercostal muscles contract and cause a
decrease in intrathoracic pressure.
Based on current guidelines in which of the following situations should supplemental oxygen be
administered - ANS Exposure to carbon monoxide and an oxygen saturation of 95%
A ventilation/perfusion mismatch occurs when. - ANS A disruption in blood flow inhibits the
exchange of oxygen and carbon dioxide in the lungs even though the alveoli are filled with fresh
oxygen
Your protocols state that during the first few minutes of working on a cardiac arrest patient,
you should provide passive ventilation. This means that you will: - ANS allow recoil of the
chest between compressions to draw air into the lungs

, Which of the following factors will cause a decreased minute volume in an adult -
ANS shallow breathing
The main advantage of the Venturi mask is: - ANS the use of its fine adjustment capabilities
in the long-term management of physiologically stable patients.
Which of the following is a late sign of hypoxia - ANS cyanosis
Central chemoreceptors located in the medulla provide feedback to increase the rate and depth
of breathing when they sense: - ANS slight increases in carbon dioxide or a decrease in the
pH of the cerebrospinal fluid.
While eating dinner, your partner suddenly grabs his throat and has a panicked look on his face.
He has a weak cough, faint inspiratory stridor, and cyanosis around the lips. You should: -
ANS stand behind him and administer abdominal thrusts.
The partial pressure of oxygen in the alveoli is___ mm Hg while the partial pressure of carbon
dioxide in the alveoli is ___ mm Hg - ANS 104, 40
The process of exchanging oxygen and carbon dioxide between the alveoli and blood of the
capillaries is called - ANS external respiration
Which of the following statements regarding oxygenation and ventilation is correct - ANS In
mines or confined places, where oxygen levels are low, ventilation may continue despite
adequate oxygenation.
Which of the following oxygen flow meters is not affected by gravity and could be used in any
position when attached to an oxygen cylinder - ANS Bourdon-gauge flowmeter
