EMS TEST Flashcards
The muscles used in the chest to allow the body to inhale and exhale are the
Intercostal muscles
At what location does the actual exchange of oxygen from inhaled air to the blood occur
Alveoli
What is the most important thing to check when doing an assessment of breathing
Adequacy of breathing
To assess the airway of an Unresponsive person the EMR should position him
Suspine on the floor
It is possible for someone to be breathing and still be drying from lack of oxygen
True
The patient who appears awake and alert will most likely have an open airway
True
Cyanosis is an early sign of respiratory distress
False
Swelling in the airway can only be a result of an allergic reaction
False
What is the most common airway obstruction
Tongue
What is the preferred method for opening the airway of the unresponsive adult without suspected spinal injury
Head tilt chin lift maneuver
What is the preferred type of suction catcher for use by the emr
Rigid
An pharyngeal airway is inserted so that the tongue doesn’t become an airway obstruction
Upside down or toward the cheek
Mental status is an important sign to assess when determining breathing adequacy because
The brain responds to hypoxia by displaying disorientation
A pulse oximeter displays a percentage of oxygen in the blood carrying element called
Hemoglobin
What term is used to describe the bluish discoloration of the lips in the late stages of hypoxia
Cyanosis
When performing a head tilt chin lift maneuver it is important that th fingers lift at the
Jawbone
The area behind the nose and mouth that air passes through first on its journey to the lungs is the
Pharynx
When properly fitted to a patients face what percentage of oxygen will a no breather mask deliver
90
When ventilating a patient using a bag valve mask pushing air quickly into the patient will most likely deliver it to the
Stomach
A patient with an airway obstruction who is able to cough and gag is said to have a
Partial obstruction
Paradoxical chest wall movement during breathing is a fracture of the ribs creating a
Flail segment
Patient who are found to not be breathing adequately should be given oxygen via
Bag valve mask
Gas exchange occurring at the alveoli is primarily between oxygen and
Carbon dioxide
An o ring is required when using a regulator to
Deliver oxygen to a patient
True
The nonbreatehr mask will deliver the highest concentration of oxygen to a patient
False
One must use oxygen when ventilating via a bag valve mask or it will not function
False
When suctioning a patient airway you should be able to clear all secretions within 15 seconds
False
