Exam Questions and CORRECT Answers
Ventilation - CORRECT ANSWER - Breathing in and out (inhalation and exhalation)
Alveolar Ventilation - CORRECT ANSWER - The amount of air that reaches the alveoli
during inhalation
Respiratory arrest - CORRECT ANSWER - When breathing completely stops
Positive Pressure Ventilation - CORRECT ANSWER - The process of forcing air and or
oxygen into the lungs when breathing has stopped
Respiratory Failure - CORRECT ANSWER - The reduction of breathing to the point at
which oxygen intake is not sufficient to support life
Respiration - CORRECT ANSWER - The diffusion of oxygen and carbon dioxide
between the alveoli and the blood and between the blood and the cells
Pulmonary Respiration - CORRECT ANSWER - The exchange of oxygen and carbon
dioxide between the alveoli and circulating blood in the pulmonary capillaries
Bag-valve mask (BVM) - CORRECT ANSWER - A handheld device with a face mask
and self-refilling bag that can be squeezed to provide artificial ventilation's to a patient
Ventuir Mask - CORRECT ANSWER - A face mask that delivers very specific
concentrations of oxygen by mixing oxygen with inhaled air
Tracheostomy mask - CORRECT ANSWER - A device designed to be placed over a
stoma or tracheostomy tube to provide supplemental oxygen
,Automatic transport ventilator (ATV) - CORRECT ANSWER - A device that provides
positive pressure ventilation's. It includes settings designed to adjust ventilation rate and volume,
is portable, and is easily carried on an ambulance
Oxygen Cylinder - CORRECT ANSWER - A cylinder filled with oxygen under pressure
Pressure regulator - CORRECT ANSWER - A device connected to an oxygen cylinder to
reduce cylinder pressure so that it is safe for delivery of oxygen to a patient
Respiratory failure is - CORRECT ANSWER - inadequacy of breathing with insufficient
oxygen intake
Respiratory failure VS respiratory distress - CORRECT ANSWER - A patient with
respiratory failure has cyanotic or gray skin color
Your patient has overdosed on a narcotic medication that was prescribed for pain after a surgical
procedure. Apparently, she took four times the prescribed dose, thinking that she could
completely eliminate the pain. This medication has been known to depress respiration's and lead

temperatures
, In ventilating a 22 year old unconscious female, a bag-valve mask should be used with -
CORRECT ANSWER - A reservoir bag, oxygen tank and a liter flow regulator, oral
airway
When prolonged ventilation need to be done on a patient and there is only one EMT on the

CORRECT ANSWER -E
Before connecting a regulator to an oxygen supply cylinder, the EMT should - CORRECT
ANSWER - crack the main valve for one second
Humidified oxygen - CORRECT ANSWER - not needed in adult patients who are being
transported for short distances
Concerns about the dangers of giving too much oxygen to patients with chronic COPD -
CORRECT ANSWER - are invalid in the out of hospital setting when clinically
appropriate to administer
The oxygen concentration of a nonrebreather mask is between what - CORRECT
ANSWER - 80% and 90%
You are treating a patient who is breathing on his own but is in respiratory distress, and his SpO2
is 93%. The flow rate of a nonrebreather mask should be - CORRECT ANSWER - 12 to
15 liters per minute
