How does CPAP improve oxygenation and ventilation in patients with
certain respiratory problems?
Select one:
A. It decreases intrathoracic pressure, which allows more room for lung
expansion.
B. It prevents alveolar collapse by pushing air into the lungs during
inhalation.
C. It forces the alveoli open and increases the concentration of oxygen in
the alveoli.
D. It pushes thick, infected pulmonary secretions into isolated areas of
the lung. - Answer-C. It forces the alveoli open and increases the
concentration of oxygen in the alveoli.
In the presence of oxygen, the cells convert glucose into energy through
a process called:
Select one:
,A. anaerobic metabolism.
B. perfusion.
C. aerobic metabolism.
D. respiration. - Answer-C. aerobic metabolism.
When testing a mechanical suctioning unit, you should turn on the
device, clamp the tubing, and ensure that it generates a vacuum pressure
of more than:
Select one:
A. 100 mm Hg.
B. 300 mm Hg.
C. 400 mm Hg.
D. 200 mm Hg. - Answer-B. 300 mm Hg.
The __________ cartilage is a firm ring that forms the inferior part of
the larynx.
Select one:
A. thyroid
B. cricoid
C. pyriform
D. laryngeal - Answer-B. cricoid
Which of the following statements regarding breathing adequacy is
correct?
, Select one:
A. A patient with slow respirations and adequate depth will experience
an increase in minute volume.
B. Patients with a grossly irregular breathing pattern usually do not
require assisted ventilation.
C. The single most reliable sign of breathing adequacy in the adult is his
or her respiratory rate.
D. Patients breathing shallowly may require assisted ventilation despite
a normal respiratory rate. - Answer-D. Patients breathing shallowly may
require assisted ventilation despite a normal respiratory rate.
The nasal cannula is MOST appropriately used in the prehospital
setting:
Select one:
A. if long-term supplemental oxygen administration is required.
B. when the patient breathes primarily through his or her mouth.
C. when the patient cannot tolerate a nonrebreathing mask.
D. if the patient's nasopharynx is obstructed by secretions. - Answer-C.
when the patient cannot tolerate a nonrebreathing mask.
In contrast to inhalation, exhalation:
Select one:
A. requires muscular effort to effectively expel air from the lungs.
B. is a passive process caused by increased intrathoracic pressure.
C. is an active process caused by decreased intrathoracic pressure.
