FISDAP Airway Exam QUESTIONS AND
CORRECT ANSWERS
Ventilation - CORRECT ANSWER movement of air in and out of the lungs
Oxygenation - CORRECT ANSWER The process of delivering oxygen to the blood by
diffusion from the alveoli following inhalation into the lungs.
Respiration - CORRECT ANSWER the actual exchange of oxygen and carbon dioxide
in the alveoli as well as the tissues of the body
tidal volume - CORRECT ANSWER Amount of air that moves in and out of the lungs
during a normal breath
residual volume - CORRECT ANSWER Amount of air remaining in the lungs after a
forced exhalation
alveolar ventilation - CORRECT ANSWER The volume of air that reaches the alveoli.
It is determined by subtracting the amount of dead space air from the tidal volume.
minute volume - CORRECT ANSWER The volume of air breathed in one minute
without conscious effort. Minute volume = Tidal Volume x (breaths/minute)
alveolar minute volume - CORRECT ANSWER The volume of air moved through the
lungs in 1 minute minus the dead space; calculated by multiplying tidal volume (minus dead
space) and respiratory rate.
vital capacity - CORRECT ANSWER The total volume of air that can be exhaled after
maximal inhalation.
,dead space - CORRECT ANSWER The portion of the tidal volume that does not reach
the alveoli and thus does not participate in gas exchange.
Does oxygen or carbon dioxide bind to hemoglobin more readily? - CORRECT
ANSWER Carbon dioxide
hypoxemia - CORRECT ANSWER decreased level of oxygen in the blood
Hypoxia - CORRECT ANSWER deficiency in the amount of oxygen reaching the
tissues
Metabolism - CORRECT ANSWER the combination of chemical reactions through
which an organism builds up or breaks down materials
pulmonary respiration - CORRECT ANSWER the exchange of oxygen and carbon
dioxide between the alveoli and circulating blood in the pulmonary capillaries
hypoxic drive - CORRECT ANSWER A "backup system" to control respiration; senses
drops in the oxygen level in the blood.
Dyspnea - CORRECT ANSWER shortness of breath
internal respiration - CORRECT ANSWER exchange of gases between the blood and
the cells of the body
Chemoreceptors - CORRECT ANSWER chemical sensors in the brain and blood
vessels that identify changing levels of oxygen and carbon dioxide
Perfusion - CORRECT ANSWER Circulation of blood within an organ or tissue in
adequate amounts to meet current needs of the cells.
, hypercarbia - CORRECT ANSWER Increased carbon dioxide level in the bloodstream.
most common airway obstruction - CORRECT ANSWER tongue
intrapulmonary shunting - CORRECT ANSWER blood entering the lungs from the
right side of the heart bypasses the alveoli and returns to the left side of the heart in an
unoxygenated state
hemothorax - CORRECT ANSWER blood in the pleural cavity
pneumothorax - CORRECT ANSWER air in the pleural cavity caused by a puncture of
the lung or chest wall (collapsed lung)
tension pneumothorax - CORRECT ANSWER a type of pneumothorax in which air
that enters the chest cavity is prevented from escaping
Hemopneumothorax - CORRECT ANSWER The accumulation of blood and air in the
pleural space of the chest.
pulmonary embolism - CORRECT ANSWER A blood clot that breaks off from a large
vein and travels to the blood vessels of the lung, causing obstruction of blood flow.
hypovolemic shock - CORRECT ANSWER A condition in which low blood volume,
due to massive internal or external bleeding or extensive loss of body water, results in
inadequate perfusion.
vasodilatory shock - CORRECT ANSWER A type of shock related to relaxation of the
blood vessels, allowing blood to pool and impairing circulation.
Aerosol Generating Procedures - CORRECT ANSWER Treatments that increase the
risk for transmission of infections that are spread through the air or by droplets; CPR
(breaths*), nebulizer, intubation, CPAP
