Question 1

Without a clear airway, the patient cannot breathe and will die in…

Answer 1

4 to 6 minutes

Question 2

The back of the throat (pharynx) divides, at its lower portion, to become

Answer 2

Windpipe (trachea) in the front
and the

food pipe (esophagus) in the back

Question 3

A small flap of tissue called the BLANK protects the tracheal opening

Answer 3

epiglottis

Question 4

The three causes of airway obstruction are

Answer 4

Tongue (90%)

Foreign bodies
(food, teeth, vomit, blood)

Swelling
(direct blows, smoke inhalation, chemical inhalation, anaphylaxis)

Question 5

Two types of airway obstruction

Answer 5

Partial (reduced air exchange)

Complete (no air exchange)

Question 6

Signs and symptoms of partial airway obstruction (4 of them)

Answer 6

Noisy breathing
Hoarseness
Stridor (high-pitched noise)
Cyanosis (turning blue)

Question 7

Signs and symptoms of complete airway obstruction (4)

Answer 7

Cyanosis (turning blue)
No air movement
Chest wall does not rise with ventilation
If conscious, unable to speak or cough

Question 8

Peripheral cyanosis affects

Answer 8

Lips and fingers

Question 9

Central cyanosis effects

Answer 9

Whole body

Question 10

3 aspects of critical interventions

Answer 10

Are essential treatments that must be performed to correct life-threatening condition

Must be performed as soon as it is recognized that they are needed

Must be completed before moving onto the next step in the primary survey

Question 11

Three methods for clearing an airway

Answer 11

Abdominal thrusts

Back blows

Chest compressions

Question 12

Describe the sequence of the three airway clearing methods

Answer 12

Abdominal thrusts on a conscious, standing or sitting patient as a first measure

Back blows on standing or sitting patients if the abdominal thrusts are ineffective

Chest compressions on supine patients, conscious or unconscious

Question 13

Up to how many abdominal thrusts and back blows?

Answer 13

5 each cycle

Question 14

The four aspects of airway and breathing

Answer 14

Blow
Flow
Show
Know

Blow – oral airway if required and oxygen.
Start assisted vents every five seconds.
Train a helper

Flow – oxygen at 10 L per minute

Show – expose chest, stabilize

Know – equilateral expansion, breathing rate and quality – ensure helpers effectiveness

Question 15

What is the timing for assisted vents?

Answer 15

Ventilate once every five seconds timed with the patients inhalation if possible

Vents should be one second in duration

Question 16

Managing a complete airway obstruction (decreased level of consciousness, non-trauma, supine)

Answer 16

Open the airway with the head tilt, chin lift and check for breathing

Check for carotid pulse

Attempt to ventilate (no air goes in)

Look in the mouth and remove any object seen, then measure and insert an oral airway

Attempt to ventilate again (no air goes in)

Remove oral airway and perform 30 chest compressions

Look in the mouth and remove any object seen (nothing seen)

Attempt to ventilate the patient (chest does not rise)

Recheck the head tilt position and attempt to ventilate again (chest does not rise)

Perform 30 chest compressions

Look in the mouth and remove any object seen (candy is removed)

Attempt to ventilate again (2 breaths go in

Train a helper to ventilate

Measure and insert and oral airway

Oxygen at 10 L flow

Expose chest and assess breathing effectiveness

Question 17

What is WERP?

Answer 17

Workplace emergency response procedures

Question 18

Patients who have profuse bleeding from the mouth or nose or who are actively vomiting must be managed in the BLANK position

Answer 18

Lateral

Question 19

You can use suction to assist the removal of fluids in the mouth when

Answer 19

Finger sweeping and gravity are not clearing the airway effectively

Question 20

If attempting to use suction when the oral airway is in place and clear,

Answer 20

Suction to the side and do not remove the oral airway

Question 21

How far does a suction catheter get inserted into the mouth?

Answer 21

Not further into the mouth than you can see

Question 22

Suction for no longer than

Answer 22

20 seconds at a time

Question 23

When maintaining oxygen flow to the patient, and if assisting ventilation,

Answer 23

Assist ventilation for 20 seconds, then suction for up to 20 seconds
