Chapters 15 & 16 Respiratory: Study Guide and Exam
Review
In contrast to negative pressure ventilation , positive pressure ventilation :
A. moves air into the esophagus and trachea
B . is the act of normal , unassisted breathing .
C. may impair blood return to the heart .
D. causes decreased intrathoracic pressure . - Correct answer✅✅ C. may impair blood return to the
heart .
The fraction of inspired oxygen ( FIO₂ ) increases with :
A . increased tidal volume
B . an increase in respirations
C. supplemental oxygen
D. forceful inhalation . - Correct answer✅✅ C. supplemental oxygen .
If you suspect that an unconscious patient has experienced a spinal injury , you should open his or her
airway by :
A. applying firm pressure to the patient's forehead and tilting the head back .
,B . carefully grasping the tongue and jaw and slowly lifting the jaw forward .
C. lifting up on the jaw while placing the head in a slightly extended position .
D. placing your fingers behind the angle of the jaw and lifting the jaw forward . - Correct answer✅✅ D.
placing your fingers behind the angle of the jaw and lifting the jaw forward .
The upper airway of an adult consists of all the structures above the :
A. glottis .
B . cricoid ring .
C. carina .
D. bronchus . - Correct answer✅✅ A. glottis .
Negative pressure ventilation occurs when :
A. the diaphragm ascends and the intercostal muscles retract .
B. air is drawn into the lungs when intrathoracic pressure decreases.
C. pressure within the chest decreases and air is forced from the lungs .
D. the phrenic nerves stop sending messages to the diaphragm . - Correct answer✅✅ B. is drawn into
the lungs when intrathoracic pressure decreases .
Normally , an adult at rest should have respirations that :
, A. have a slightly reduced tidal volume and normal rate
B . are 20 to 24 breaths / min with adequate chest rise .
C. are adequate to sustain a heart rate of 80 beats / min .
D. follow a regular pattern of inhalation and exhalation . - Correct answer✅✅ D. follow a regular
pattern of inhalation and exhalation .
Pulse oximetry is used to measure the :
A. percentage of hemoglobin that is saturated with oxygen .
B . percentage of carbon dioxide that is eliminated from the body .
C. amount of oxygen dissolved in the plasma portion of the blood .
D. exchange of oxygen and carbon dioxide at the cellular level . - Correct answer✅✅ A. percentage of
hemoglobin that is saturated with oxygen .
Tenting of the skin under the jaw often occurs when airway devices are inadvertently inserted into the :
A. piriform fossae .
B . hypopharyngeal space .
C. laryngopharynx .
