MANAGEMENT Terms Questions and
Correct Answers
You have inserted an oral airway and are ventilating
an apneic woman with a bag-valve mask. She suddenly
begins regurgitating large amounts of vomit. You
should: Answer: roll her onto her side and remove
the oral airway
CPAP is indicated for patients who: Answer: have
pulmonary edema and can follow verbal commands
Hypoxia is MOST accurately defined as: Answer:
inadequate O2 to the tissues and cells
How does positive-pressure ventilation affect cardiac
output? Answer: it increases intrathoracic pressure,
which decreases venous return to the heart and causes
a decrease in cardiac output
The MOST serious complication associated with using a
nasopharyngeal airway in a patient with trauma to the
head or face is: Answer: penetrating the cranium
Pretest - Stuvia US
,2
The nasal cannula is MOST appropriately used in the
prehospital setting: Answer: when the pt cannot
tolerate a nonrebreathing mask
In the presence of oxygen, the cells convert glucose
into energy through a process called: Answer: aerobic
metabolism
An adult at rest should have a respiratory rate that
ranges between: Answer: 12-20 breaths/min
All of the following will help minimize the risk of gastric
distention when ventilating an apneic patient with a
bag-valve mask, EXCEPT: Answer: increasing the
amount of delivered tidal volume
Tidal volume is defined as the volume of air that:
Answer: moves into/out of the lungs in a single
breath
A 37-year-old male has an apparent foreign body
airway obstruction. He is conscious and alert and is
coughing forcefully. His skin is pink, warm, and moist.
The MOST appropriate treatment for this patient

The jaw-thrust maneuver is used to open the airway of
patients with suspected: Answer: cervical spine
injuries
You and your partner are treating a 66-year-old man
who experienced a sudden onset of respiratory
distress. He is conscious but is unable to follow simple
verbal commands. Further assessment reveals that his
breathing is severely labored and his oxygen saturation
is 80%. You should: Answer: assist his ventilations
with a BVM
Which of the following patients would MOST likely
require insertion of an oropharyngeal airway? Answer:
a 40-year-old unconscious pt with slow, shallow
respirations
Pretest - Stuvia US
, 4
Oxygen toxicity is a condition in which: Answer:
cellular tissue damage occurs from excessive O2 levels
in the blood
Which of the following would NOT cause a decrease in
tidal volume? Answer: deep respirations
If ventilation is impaired, carbon dioxide levels in the
bloodstream will increase. This condition is called:
Answer: hypercarbia
The actual exchange of oxygen and carbon dioxide
occurs in the: Answer: alveolar sacs
The purpose of the pin-indexing system for compressed
gas cylinders is to: Answer: ensure that the correct
regulator is used for the cylinder
On which of the following patients would it be MOST
appropriate to use the flow-restricted, oxygen-powered
ventilation device? Answer: a 21-year-old male with
traumatic cardiac arrest
Based on current guidelines, in which of the following
situations should supplemental oxygen be
