Where does gas exchange of oxygen and carbon dioxide occur?
a. larynx
b. bronchioles
c. alveoli
d. main stem bronchi - ANSWER Alveoli
The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during
the process of breathing in and breathing out. Oxygen breathed in from the air passes
through the alveoli and into the blood and travels to the tissues throughout the body.
What is the primary role of the epiglottis?
a. bringing oxygen into circulation
b. aids in food digestion
c. assist air flow to the larynx
d. prevent aspiration while eating - ANSWER Prevent aspiration while eating
The main job of the epiglottis is to close over the trachea while you're eating to prevent food
entering your airway.
What is the PRIMARY role of the mediastinum?
2
,a. Protects vital structures of the chest
b. Protects your diaphragm from collapse
c. Protects your lungs from collapse
d. Surrounds the heart's four chambers - ANSWER protects vital structures of the
chest
The mediastinum protects many vital structures including the heart, large vessels, the
trachea, and critical nerves.
You respond to a 8 year old male who states he is having trouble breathing. His respiratory
rate is 44 breaths/min and you notice accessory muscle use on exam. You can hear an
audible wheeze present. What should your initial step be?
a. Start BVM ventilations
b. Attempt a head tilt-chin lift
c. Obtain his oxygen saturation
d. Gather a SAMPLE history - ANSWER Obtain his oxygen saturation
This patient is able to speak so the airway is patent, we don't have any oxygen data so we
need that before we can go ahead with oxygen administration. This will give the final piece
of info to start assessing his current status.
You are called to the home of a 4 year old female patient. The patient has a persistent
"barking cough" and has stridor on exam. The mother tells you that this has gotten worse
over the last few nights, until tonight she had a "hard time" breathing. What do you suspect?
a. Asthma Exacerbation
b. Bronchiolitis
c. Epiglottitis
d. Croup - ANSWER Croup
3
, Remember the keys for croup, barking cough, stridor, gradual onset, typically seen in young
children. Epiglottitis can occur at any age and has drooling, painful swallowing, stridor and a
more rapid onset, no barking cough.
From the list below name three action steps you can take to help patients with croup or
epiglottitis. (Pick 3)
a. Keep oxygen saturation above 94%
b. Keep the patient calm
c. Begin CPR if the patient has a pulse less than 100
d. Begin bag valve mask ventilations with rapid transport
e. Use blow-by oxygen
f. Immediately begin non-rebreather mask at 15LPM - ANSWER a. keep oxygen
saturation above 94%
b. keep patient calm
e. use blow-by oxygen
You are about to place an airway adjunct into your patient. Which situation would you NOT
place a nasopharyngeal airway?
a. A semiconscious child who just had a seizure
b. A patient with ecchymosis behind one ear
c. An unconscious patient with an intact gag reflex
d. An semiconscious adult who cannot maintain their own airway - ANSWER a patient
with ecchymosis behind one ear
Bruising behind one ear is known as the "Battle sign" and an indication of a basilar skull
fracture, which is a severe head injury. Use of a nasopharyngeal airway with severe head
injuries is contraindicated.
You are transporting a 53 year-old male who complains of shortness of breath, dizziness,
numbness in his hands, and a dry mouth. His vital signs are: blood pressure 118/80 mmHg,
HR 120, RR of 32, SpO2 99%, and ETCO2 of 26 mmHg. What do you suspect?
