22) What device is used to perform mouth-to-mask ventilation?
A) Pocket face mask
B) Bag-valve mask
C) Stoma
D) Automatic transport ventilator
Objective: 10.13
23) What is NOT one of the basic parts of a bag-valve-mask system?
A) Self-refilling shell
B) Non-jam valve
C) Be nonrebreathing
D) 15/25 respiratory fitting
Objective: 10.13
24) You are aggressively ventilating an adult patient with a bag-valve mask when you notice that
his previously strong pulse is getting weaker. You should:
A) increase the concentration of oxygen.
B) reduce the concentration of oxygen.
C) reduce the volume of the ventilations.
D) begin chest compressions.
Objective: 10.14

25) You and your EMT partner are preparing to ventilate an elderly non-trauma patient who has a
stoma. Your partner performs the head-tilt, chin-lift maneuver and you ask him to return the
patient's head to a neutral position. "Why? This is not a pediatric patient!" your partner protests.
What would you say?
A) Elderly patients should never have their heads tilted back because spinal curvatures are
common and can prevent airway positioning.
B) It is not necessary to position the airway of a stoma breather when providing ventilations.
C) Stoma breathers should only have their airways positioned after placement of the ventilation
device.
D) Using the head-tilt, chin-lift prior to clearing any mucus plugs from the stoma can cause
airway occlusion.
Objective: 10.15
26) A 21-year-old patient presents with labored breathing and audible wheezes, heart rate of 124,
respiration 36; he has significantly altered mentation. What is the treatment for this patient?
A) Supplement the breaths with high-concentration oxygen through a nonrebreather mask.
B) Use a pocket mask, which will provide adequate oxygen to improve the patient's condition.
C) Ventilate with a bag-valve mask with high oxygen or FROPVD.
D) Give mouth-to-mouth breathing with a nasal cannula, providing the patient with an increase
of oxygen.
Objective: 10.16

27) What is the percentage of oxygen provided by connecting a high flow of oxygen to the
oxygen inlet found on a pocket mask?
A) 50%
B) 21%
C) 100%
D) 16%
Objective: 10.16
28) Your patient is a 55-year-old man with a history of chronic bronchitis. You have been called
to his home today because of an increase in his level of respiratory distress. The patient is on 2
liters per minute of oxygen by nasal cannula at home. Your assessment reveals difficulty
speaking due to shortness of breath, leaning forward to breathe, a productive cough, and a
respiratory rate of 32 per minute. Which of the following is true concerning the best course of
action for this patient?
A) Because increased blood levels of carbon dioxide are the primary stimulus to breathe, you
should encourage the patient to rebreathe his exhaled air from a paper bag.
B) You should increase the patient's oxygen flow rate to deliver adequate amounts of oxygen to
his tissues. If his respiratory rate decreases, you can assist him with a bag-valve-mask device.
C) You should increase the patient's oxygen flow rate until his respiratory rate decreases and then
resume oxygen administration at 2 liters per minute.
D) You should not increase the patient's oxygen flow rate because of his likely dependence on a
hypoxic drive to stimulate breathing.
Objective: 10.16

29) Which of the following is the best device to deliver high-concentration oxygen to a breathing
patient?
A) Simple face mask
B) Nonrebreather mask
C) Nasal cannula
D) Oropharyngeal airway
Objective: 10.16
30) Your patient is a 65-year-old male with a history of COPD. He is sitting up and complaining
of a severe shortness of breath. You should:
A) suction the airway with a rigid suction catheter.
B) administer 4 lpm of oxygen via nasal cannula.
C) insert a nasal airway and ventilate.
D) apply a nonrebreather mask giving 15 lpm of oxygen.
Objective: 10.17
31) A nonrebreather mask at 12 to 15 liters per minute will generally provide the patient what
percentage of oxygen?
A) 80-100
B) 16-21
C) 24-44
D) 90-100
Objective: 10.17

32) You are transporting a 44-year-old female with chest pain and sudden respiratory distress.
She is agitated, anxious, and refuses to have a nonrebreather mask applied. Which of the
following is the best option?
A) Use a nasal cannula instead.
B) Have her breathe into a paper bag to control her hyperventilation.
C) Do not make further attempts to administer oxygen as it will only agitate the patient further.
D) Consult with medical control about restraining the patient.
Objective: 10.17
33) Before applying a nonrebreather mask, the EMT should take what action?
A) Insert a properly sized oropharyngeal airway.
B) Connect the mask to a humidified oxygen source and wait for the patient's heart rate to slow.
C) Make sure the oxygen supply has greater than 2,000 psi in the tank.
D) Inflate the reservoir bag and make sure the bag does not deflate during inspiration.
Objective: 10.18

34) Which of these patients would require a tracheostomy mask for supplemental oxygen
administration?
A) A patient with a stoma
B) A patient with quadriplegia
C) A patient with chronic bronchitis
D) A patient with upper airway inflammation
Objective: 10.18
35) A ________ is NOT typically used in the prehospital setting for oxygen administration.
A) nasal cannula
B) partial rebreather mask
C) regulator
D) tracheostomy mask
