(MULTIPLE)
An elderly male who is short of breath is on home oxygen. He is wearing a nasal
cannula connected to an oxygen tank with the flow regulator set to 3 liters per minute.
As a knowledgeable EMT, you should recognize that the patient is getting
approximately what percentage of oxygen with each breath? - 32%
Which one of the following statements about ventilation of a non breathing patient
through a stoma is true?
A nasal airway should be inserted into the stoma prior to any attempt at ventilating the
patient.
A head-tilt, chin-lift or jaw-thrust maneuver is still needed to open the airway.
The EMT should ventilate through the stoma with a child-sized face mask attached to a
bag-valve mask.
Mouth-to-stoma ventilation is an easy and safe procedure to perform on a non breathing
patient. - The EMT should ventilate through the stoma with a child-sized face mask
attached to a bag-valve mask.
You arrive at a residence for a male patient who is unresponsive. As you enter the
room, you observe an obese male lying on a recliner. His eyes are closed, and he has
gurgling respiration's. While your partner quickly performs a primary assessment, you
should immediately prepare to: - Suction the airway
Assessment findings for an alert and oriented patient complaining of shortness of breath
reveal an open airway and strong radial pulse, accompanied by skin that is cool and
diaphoretic. The depth of respiration's is adequate, and breath sounds include wheezing
throughout the lungs. Vital signs are a pulse of 124, respiratory rate of 24, blood
pressure of 146/82 mmHg, and SpO2 93%. The patient has a history of asthma for
which he takes medications. How should you administer oxygen to this patient? -
Nonrebreather mask
Your paramedic partner has applied continuous positive airway pressure (CPAP) to a
patient in respiratory distress from congestive hear failure (CHF). As an EMT, you
realize that this should benefit the patient by: - forcing fluid in the lungs back into the
bloodstream
,Which one of the following statements indicates the EMT has an accurate
understanding of the bronchioles?
"They are large airways located before the carina and are made of cartilage."
"They are small passages located in the lower airway that have smooth muscle
surrounding them."
"They are large structures that pass oxygen from the lungs directly into the
bloodstream."
"They are small air sacs located just before the alveoli." - "They are small passages
located in the lower airway that have smooth muscle surrounding them."
You must suction a male patient who has a decreased ability to swallow secondary to a
previous stroke. He also has a history of smoking and lung cancer. Which one of the
following represents the most appropriate personal protective equipment that you
should use with this patient?
Gloves
Gloves, gown, HEPA respirator mask
Gloves, mask with face shield
Gloves, and goggles - gloves, mask with face shield
A patient with a stoma and tracheostomy tube is responsive to painful stimuli and
breathing shallowly at 6 times per minute. He has cyanosis of the fingertips and a weak,
rapid radial pulse. Which one of the following is best in providing respiratory care to this
patient?
Use a continuous positive pressure device over the stoma.
Attach the bag-valve device directly to the tracheostomy tube. - Attach the bag-valve
device directly to the tracheostomy tube
The EMT is correctly performing the jaw-thrust maneuver when she:
Opens the airway by slightly extending the head and thrusting the jaw upward.
Places one hand on the forehead and lifts the jaw upward with her other hand.
Places her hands on the side of the patient's head and lifts the jaw upward.
, Maintains the head in a neutral position and slightly tilts the head backward - Places her
hands on the side of the patient's head and lifts the jaw upward.
It can help minimize gastric distention associated with positive pressure ventilation - It
can help minimize gastric distention associated with positive pressure ventilation.
You are observing an EMT insert an oropharyngeal airway into the airway of a 36-year-
old male who has overdosed on a street drug. Which one of the following observations
indicates correct technique?
The EMT uses a tongue depressor to press the back of the tongue downward, and then
inserts the oral airway upside-down
The airway is inserted in its normal anatomic position until the flange of the airway is 1
cm above the lips.
The oral airway is introduced sideways into the mouth, and then rotated 180 degrees
once it has reached the base of the tongue.
The airway is inserted into the mouth upside-down and is then turned 180 degrees once
it contacts the soft palate. - The airway is inserted into the mouth upside-down and is
then turned 180 degrees once it contacts the soft palate.
You are watching an EMT prepare the ambulance for the upcoming shift. In regards to
oxygen cylinders and equipment, which one of the following requires immediate
intervention?

He makes certain that all valves on the empty oxygen tanks are closed
He cleans a dirty oxygen tank with a petroleum-based agent.
He lays tanks on the floor when removed from the ambulance. - He cleans a dirty
oxygen tank with a petroleum-based agent.
A patient complaining of shortness of breath and a history of asthma has the following
vital signs: pulse 96, respiration's 20, blood pressure 132/86, and SpO2 92% on room
air. Mild wheezing is noted bilaterally and the patient states that she has run out of her
rescue inhaler (albuterol). Regarding the patient's respiratory status, you would
administer:
4 lpm O2 through a nasal cannula
12 lpm O2 through a nonrebreather
