How does positive-pressure ventilation affect cardiac output?
A. It increases intrathoracic pressure, which decreases venous return to the heart
and causes a decrease in cardiac output
B. There is no effect on cardiac output because positive-pressure ventilation is
the act of normal breathing.
C. It decreases intrathoracic pressure, which facilitates venous return to the heart
and increases cardiac output.
D. It causes pressure in the chest to decrease, which increases stroke volume and
cardiac output - CORRECT ANSWER>>>>A. It increases intrathoracic pressure,
which decreases venous return to the heart and causes a decrease in cardiac output
Hypoxia is MOST accurately defined as:
A. High oxygen levels in the tissues and cells
B. A decrease in arterials oxygen levels.
C. Inadequate oxygen to the tissues and cells
D. An increase in carbon dioxide in the blood - CORRECT ANSWER>>>>C.
Inadequate oxygen to the tissues and cells.
In contrast to inhalation, exhalation:
Page 1 of 22
,A. Occurs when the diagram lowers and expels air from the lung
B. Is an active process caused by decreased intrathoracic pressure
C. Is a passive process caused by increased intrathoracic pressure
D. Requires muscular effort to effectively expel air from the lungs. - CORRECT
ANSWER>>>>C. Is a passive process caused by increased intrathoracic pressure
In the presence of oxygen, the cells convert glucose into energy through a process
called:
A. Anaerobic metabolism
B. Respiration
C. Perfusion
D. Aerobic metabolism - CORRECT ANSWER>>>>D. Aerobic metabolism
In which of the following patients would the head tilt-chin lift maneuver be the
MOST appropriate method of opening the airway?
A. A 45-year-old male who is semiconscious after falling 20 feet
B. A 50-year-old male who is unconscious following head trauma
C. A 37-year-old female is found unconscious in her bed
D. A 24-year-old male who is found unconscious at the base of a tree - CORRECT
ANSWER>>>>C. A 37-year-old female is found unconscious in her bed
Inhalation occurs when the:
A. Diaphragm and intercostal muscles ascend and causes an increase in intrathoracic
pressure
B. Diaphragm ascends and the intercostal muscles contract, causing a decrease in
intrathoracic pressure
Page 2 of 22
, C. Diaphragm and intercostal muscles relax and cause an increase in intrathoracic
pressure.
D. Diaphragm and intercostal muscles contract and cause a decrease in intrathoracic
pressure -
CORRECT ANSWER>>>>D. Diaphragm and intercostal muscles contract and
cause a decrease in intrathoracic pressure
Proper technique for suctioning the oropharynx of an adult patient includes:
A. Removing large, solid objects with a tonsil-tip suction catheter
B. Suctioning while withdrawing the catheter fro the oropharynx
C. Continuously suctioning patients with copious oral secretion
D. Suctioning for up to 1 minute if the patient is well oxygenated - CORRECT
ANSWER>>>>B. Suctioning while withdrawing the catheter fro the oropharynx
The jaw-thrust maneuver is used to open the airway of patients with suspected:
A. Mandibular fractures
B. Upper airway swelling
C. Copious oral secretions
D. Cervical spine injury - CORRECT ANSWER>>>>D. Cervical spine injury
The MOST serious complication associated with using a nasopharyngeal airway in
a patients with trauma to the head or face is:
A. Causing severe bleeding
B. Fracturing the septum
C. Penetrating the cranium
