Airway
Prior to applying a nonrebreathing mask to a patient, you must ensure that the
reservoir bag is fully inflated
The leaf-shaped structure located superior to the larynx is called the:
epiglottis.
The process of exchanging oxygen and carbon dioxide between the alveoli and the blood of the capillaries is called
external respiration
o select the proper size oropharyngeal airway, you should measure from the:
corner of the mouth to the earlobe.
Inhalation occurs when
decrease in intrathoracic pressure and diaphragm and intercostal muscles contract
A patient who is suspected of being hypoxic and is breathing adequately should be given supplemental oxygen with a:
nonrebreathing mask.
nasopharyngeal airway is MOST beneficial because it
can maintain a patent airway in a semiconscious patient with a gag reflex
testing a mechanical suctioning unit vacuum pressure should be no more than
300 mm Hg
Proper technique for suctioning the oropharynx of an adult patient includes
suctioning while withdrawing the catheter from the oropharynx
Irregular respirations characterized by an increasing rate and depth of breathing followed by periods of apnea are called:
Cheyne-Stokes respirations.
You are ventilating a patient with a stoma and air is escaping you should
seal the mouth and nose
suction times for Adult? child? infant?
adult 15sec
child 10sec
infant 5sec
A nasopharyngeal airway is inserted
with the bevel facing the septum if inserted into the right nare.
In contrast to inhalation, exhalation:
is a passive process caused by increased intrathoracic pressure
significant complication associated with oropharyngeal suctioning i
hypoxia due to prolonged suction attempts
The hypoxic drive is influenced by
low blood oxygen levels.
infant Resp rate range
25-50 breaths/min
Central chemoreceptors located in the medulla provide feedback to increase the rate and depth of breathing when they sense:
slight increases in carbon dioxide or a decrease in the pH of the cerebrospinal fluid.
Complications associated with using a manually triggered ventilation device include
lung tissue injury and gastric distention
Gas exchange in the lungs is facilitated by
adequate amounts of surfactant
The diaphragm is innervated by the _________ nerve, which allows it to contract.
The diaphragm is innervated by the _________ ner
Which of the following is a late sign of hypoxia?
Cyanosis
how is Increased cardiac output associated with carbon dioxide
it increases the amount of exhaled carbon dioxide
Intrapulmonary shunting occurs when
blood coming from the right side of the heart bypasses nonfunctional alveoli
