EMT RESPIRATORY: PRACTICE TEST QUESTIONS WITH
ACCURATE SOLUTIONS
1) If an adult patient presents with a respiratory rate of 26 breaths/min, your initial
action should be to:
A) begin assisting his ventilations with a BVM
B) apply the pulse oximeter and assess his oxygen saturation
C) evaluate his mental status and the depth of his respirations
D) apply oxygen via a NRB and take his vital signs -- Correct Answer ✔✔ D)
apply oxygen via a NRB and take his vital signs
2) Shallow breathing is an indication of:
A) decreased TV
B) increased minute volume
C) increased oxygen intake
D) severe hypocarbia -- Correct Answer ✔✔ A) decreased TV
3) You are ventilating an apneic 50 y/o woman with a BVM. After squeezing the bag and
noting visible chest rise, you should:
A) squeeze the bag again in 3 seconds
B) thoroughly suction the patient's oropharynx
C) reopen the airway and ventilate again
D) allow the patient to completely exhale -- Correct Answer ✔✔ C) reopen
the airway and ventilate again
, 4) A patient with a mild foreign body airway obstruction:
A) is typically not cyanotic
B) presents with a weak cough
C) has a low oxygen saturation
D) has progressive difficulty breathing -- Correct Answer ✔✔ A) is typically
not cyanotic
5) Which of the following interventions would result in passive ventilation?
A) chest recoil during chest compressions
B) ventilation with a BVM
C) high-flow oxygen with an NRB
D) CPAP device set to greater than 10 cm H2O -- Correct Answer ✔✔ A)
chest recoil during chest compressions
6) To ensure that you deliver the highest concentration of oxygen with an NRB, you
should:
A) set the flow rate to at least 10-12 L/min
B) securely fasten the mask to the patient's face
C) make sure that the reservoir bag is pre-inflated
D) cover the one-way valves on the oxygen mask -- Correct Answer ✔✔ C)
make sure that the reservoir bag is pre-inflated
7) What is the function of pulmonary surfactant?
A) it carries fresh oxygen from the lungs to the left side of the heart
B) it dilates the bronchioles in the lungs and enhances the flow of air
C) it lubricates the alveolar walls and allows them to expand and recoil
D) it facilitates the production of mucus, which is expelled during coughing --
Correct Answer ✔✔ C) it lubricates the alveolar walls and allows them to
expand and recoil
