Which of the following would MOST likely occur if an adult patient is breathing at a rate
of 45 breaths/min with shallow depth? - CORRECT ANSWER Most of his or her
inhaled air will not go beyond the anatomic dead space.
A 40-year-old man is conscious, but has an increased rate of breathing. You should: -
CORRECT ANSWER assess the regularity and quality of breathing.
The respiratory system functions by: - CORRECT ANSWER bringing oxygen into the
lungs and eliminating carbon dioxide.
If an adult patient presents with a respiratory rate of 26 breaths/min, your initial action
should be to: - CORRECT ANSWER evaluate his mental status and the depth of his
respirations.
Which of the following is the MOST correct technique for ventilating an apneic adult who
has a pulse - CORRECT ANSWER Deliver each breath over 1 second at a rate of 10
to 12 breaths/min.
A 22-year-old male has a shard of glass impaled in his cheek. You look inside his mouth
and see minor bleeding. The patient is conscious and alert with adequate breathing.
You should: - CORRECT ANSWER carefully stabilize the shard of glass and allow
him to suction his own mouth.
Which of the following signs or symptoms is indicative of cerebral hypoxia? - CORRECT
ANSWER Decreased level of consciousness
A 60-year-old female is found unresponsive. She is cyanotic, is making a snoring sound
while she breathes, and has a slow respiratory rate. You should - CORRECT ANSWER
manually open her airway.
You are ventilating an apneic adult with a bag-mask device and high-flow oxygen. Her
pulse rate is 130 beats/min and she has cyanosis to her face and chest. The MOST
reliable indicator of adequately performed ventilations in this patient is: - CORRECT
ANSWER a decrease in her heart rate to 90 beats/min.
, During the inhalation phase of breathing: - CORRECT ANSWER pressure within the
thorax decreases and air is drawn into the lungs.
In which of the following situations should the jaw-thrust maneuver be used? -
CORRECT ANSWER When the mechanism of injury is unclear
An unresponsive patient's respirations are 26 breaths/min and shallow. The MOST
appropriate treatment includes - CORRECT ANSWER assisted ventilations with
100% oxygen.
What is the function of pulmonary surfactant? - CORRECT ANSWER It lubricates the
alveolar walls and allows them to expand and recoil.
Oxygen that is administered through a nasal cannula would be of LEAST benefit to a
patient who: - CORRECT ANSWER breathes through his or her mouth
Which of the following occurs during positive-pressure ventilation? - CORRECT
ANSWER Intrathoracic pressure increases
You are administering oxygen at 15 L/min to a patient with respiratory distress. If you
are using a D cylinder (cylinder constant, 0.16), which reads 1,500 psi, how long will it
take before you need to replace the oxygen cylinder? - CORRECT ANSWER 14
minutes
An unresponsive apneic patient's chest fails to rise after two ventilation attempts. You
should: - CORRECT ANSWER immediately proceed to chest compressions
Hypoxia is defined as: - CORRECT ANSWER inadequate oxygen to the body's cells
and tissues.
Which of the following airway sounds indicates a lower airway obstruction? - CORRECT
ANSWER Wheezing
As you begin ventilating an unresponsive apneic man, you hear gurgling in his upper
airway. Your MOST immediate action should be to: - CORRECT ANSWER quickly
turn the patient onto his side so secretions can drain.
Snoring respirations in an unresponsive patient are usually the result of: - CORRECT
ANSWER upper airway obstruction by the tongue.
During your assessment of a trauma patient, you note massive facial injuries, weak
radial pulses, and clammy skin. What should be your MOST immediate concern? -
CORRECT ANSWER Potential obstruction of the airway
To ensure you deliver the highest concentration of oxygen with a nonrebreathing mask,
you should: - CORRECT ANSWER make sure that the reservoir bag is preinflated.
