5 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

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

7 First aid codes of practice in Australia are primarily designed to:

Replace ARC clinical guidelines with simpler rules
Provide guidance on meeting Work Health and Safety obligations for first aid
Apply only to registered healthcare professionals

8 CPR should be stopped when which of the following occurs?

The casualty shows no improvement after 5 minutes
Emergency services arrive and take over, the casualty shows clear signs of life, or you are too exhausted to continue

10 How often does the ARC recommend that CPR skills and knowledge be renewed?

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 What is the correct chest compression rate for adult CPR according to ARC guidelines?

60–80 compressions per minute
80–100 compressions per minute
100–120 compressions per minute
120–140 compressions per minute

14 For adult CPR, where should the heel of your hand be placed for chest compressions?

On the upper third of the breastbone
On the centre of the chest, on the lower half of the sternum
On the left side of the chest, directly over the heart
Just below the tip of the sternum (xiphoid process)

15 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

16 In a workplace or community context, 'duty of care' means:

You are legally required to perform CPR on anyone who collapses near you
You have a legal obligation to take reasonable care to avoid causing harm to others
Only qualified healthcare professionals have a duty of care
You must continue CPR indefinitely until professional help arrives

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

2 cm
3 cm
5 cm
8 cm

18 Before an AED delivers a shock, the first aider must:

Continue chest compressions throughout the shock
Ensure no one is touching the casualty
Remove the AED pads and reposition them
Apply additional gel to the pads

19 A workplace AED requires regular servicing and consumable checks (battery and pads) to ensure it is ready for use.

True
False

20 How does chest compression technique differ for an infant (under 1 year) compared with an adult?

Both hands are used, the same as for an adult
Two fingers are used, placed just below the nipple line on the centre of the chest
The heel of one hand is placed on the upper sternum
The flat of the palm covers the entire sternum
