Shared openly so bystanders know what happened
Released to the media if the incident occurred in a public place
Kept confidential and shared only with those who have a legitimate need to know
Recorded in a public incident register immediately

8 When an AED analyses the heart rhythm and advises 'No shock advised', the first aider should immediately:

True
False

12 Tilting the head back and lifting the chin opens the airway by lifting the tongue away from the back of the throat.

True
False

13 The chain of survival describes the sequence of actions that gives a cardiac arrest casualty the best chance of survival. Which option correctly lists the first three links in order?

Call 000 → begin CPR → attach AED
Early recognition and call for help → early CPR → early defibrillation
Check for danger → begin CPR → call 000
Begin CPR → call 000 → attach AED

14 When calling 000 to report a cardiac arrest, which information should you be prepared to give the operator?

The casualty's Medicare number and GP details
Your exact location, the nature of the emergency and the number of casualties
Only your name and the phone number you are calling from
Your workplace incident report number

15 What is the minimum depth for chest compressions in an adult during CPR?

2 cm
3 cm
5 cm
8 cm

16 Which of the following is a resuscitation barrier device used to reduce infection risk during rescue breathing?

Latex examination gloves
Pocket mask or face shield
Safety glasses
Disposable apron

17 For a conscious adult casualty, implied consent is sufficient — you do not need to ask permission before beginning first aid.

True
False

18 Before approaching a collapsed casualty, what is the first action a first aider should take?

Begin CPR immediately
Check for dangers to yourself, the casualty and bystanders
Open the casualty's airway
Call 000

19 After providing CPR, a rescuer may experience psychological distress. The appropriate response is to:

Ignore the feelings — they will pass on their own
Seek support from colleagues, a supervisor or professional support services as needed
Only seek help if the distress lasts more than a month

20 An unconscious casualty cannot give verbal consent to treatment. In this situation a first aider should:

Wait until the casualty regains consciousness
Provide first aid under the principle of implied consent
Only act if a family member is present to consent on their behalf
Call 000 and wait for instructions before touching the casualty
