A patient who is suspected of being hypoxic and is breathing adequately should be given supplemental oxygen with a:
non-rebreathing mask
mouth-to-mouth device
bag-mask device
nasal cannula
An oxygen cylinder should be taken out of service and refilled when the pressure inside it is less than:
500 psi
200 psi
1,500 psi
1,000 psi
At a flow rate of 6 L/min, a nasal cannula can deliver an approximate oxygen concentration of up to:
35%
24%
52%
44%
Gas exchange in lungs is facilitated by:
adequate amounts of surfactant
surfactant-destroying organisms
pulmonary capillary constriction
water or blood within alveoli
High- flow oxygen with a nasal cannula during the preoxygenation phase of endotracheal intubation is called:
apneic oxygenation
denitrogenation
passive ventilation
active ventilation
Irregular respirations characterized by an increasing rate and depth of breathing followed by periods of apnea are called:
eupneic respirations
ataxic respirations
Cheyne-Stokes respirations
agonal respirations
Oxygen toxicity is a condition in which:
decreased levels of oxygen in the blood result in free radical production.
cellular tissue damage occurs from excessive oxygen levels in the blood.
excessive blood oxygen levels cause the hypoxic patient to stop breathing.
significantly low levels of oxygen in the blood damage de cellular tissue.
Structures of the lower airway include all of the following, EXCEPT the:
the epiglottis
the trachea
bronchioles
alveoli
The diaphragm is innervated by the __________ nerve, which allows it to contract.
phrenic
vestibulocochlear
hypoglossal
vagus
The hypoxic drive is influenced by:
high blood oxygen levels
low blood oxygen levels
low blood carbon dioxide levels
high blood carbon dioxide levels
The presence of elevated carbon dioxide levels in the blood is called:
hypoxemia
hypercarbia
acidosis
hypoxia
The pressure of gas in a full cylinder of oxygen is approximately __________ pounds per square inch (psi).
1,000
500
2,000
3,000
