Q1Which statement about bystander duties and Good Samaritan behaviour is incorrect?

A If the casualty is unconscious, consent is generally treated as implied for life-saving help.
B A bystander should give clear tasks such as calling an ambulance, bringing an AED, or controlling the crowd.
C A bystander should record and share crowd videos to prove that help was given.
D A bystander should hand over facts such as what happened, what first aid was given, and when symptoms changed.
Explanation

Good Samaritan behaviour encourages safe help in good faith, not careless or intrusive conduct. A bystander should organise help, call emergency services, bring an AED if available, protect privacy, and give an accurate handover to trained responders. Making or sharing crowd videos violates the privacy rule and does not improve care. Clear tasks and factual handover are useful, while implied consent applies when an unconscious person needs life-saving help.

Q2Read the statements and choose the correct answer. Statement 1: Fainting is usually a brief loss of consciousness due to reduced blood flow to the brain, and the person often improves after lying flat. Statement 2: Shock may follow heavy bleeding, burns, dehydration, infection, allergy, or trauma, and it must be treated as an emergency.

A Statement 1 is true, but Statement 2 is false
B Statement 1 is false, but Statement 2 is true
C Both statements are false
D Both statements are true
Explanation

Fainting and shock should not be treated as the same condition. Fainting is usually brief and is linked to reduced blood flow to the brain; laying the person flat, loosening tight clothing, giving fresh air, and raising the legs when there is no injury can help. Shock is more dangerous and may follow bleeding, burns, dehydration, infection, allergy, or trauma. Pale, cold, sweaty skin, weakness, restlessness, confusion, or great thirst mean urgent help is needed.

Q3Match the first-aid situation with the correct immediate response. List I: 1. Heavy bleeding from a wound 2. Cloth over the wound becomes soaked with blood 3. Ordinary wound without life-threatening limb bleeding 4. Burn on the skin List II: a. Add another layer and continue pressure b. Cool under cool running water c. Apply firm direct pressure with a clean dressing d. Do not use a tourniquet routinely

A 1-c, 2-a, 3-d, 4-b
B 1-a, 2-c, 3-d, 4-b
C 1-c, 2-b, 3-d, 4-a
D 1-d, 2-a, 3-c, 4-b
Explanation

Heavy bleeding is controlled first by firm direct pressure with a clean dressing because rapid blood loss can lead to shock. If the cloth becomes soaked, it should not be repeatedly removed; another layer is added on top while pressure continues. A tourniquet is not routine first aid for ordinary wounds and is reserved for severe life-threatening limb bleeding with trained help or clear guidance. Burns are managed by early cooling under cool running water, not by pressure or home remedies.

Q4Which set gives the correct adult CPR figures when rescue breaths are being given?

A 60-80 compressions per minute, 3 cm depth, 15:2 ratio
B 100-120 compressions per minute, 2 cm depth, 30:2 ratio
C 100-120 compressions per minute, about 5 cm depth, 30:2 ratio
D 120-150 compressions per minute, about 5 cm depth, 50:2 ratio
Explanation

The high-yield adult CPR figures are a compression rate of 100-120 per minute, a depth of about 5 cm, and a 30:2 compression-to-breath ratio when rescue breaths are given. These figures maintain blood flow while limiting long pauses. Lower rates or shallow compressions reduce the value of CPR, while faster rates and incorrect ratios make the technique less controlled.

Q5Arrange the AED steps in the safest order after an adult casualty is found unresponsive and not breathing normally. Step 1: Turn on the AED Step 2: Expose and dry the chest Step 3: Attach the pads as shown Step 4: Keep everyone clear while the device analyses Step 5: Press the shock button only if instructed, then resume CPR

A 1 - 2 - 3 - 4 - 5
B 2 - 3 - 1 - 5 - 4
C 1 - 3 - 4 - 2 - 5
D 1 - 2 - 5 - 3 - 4
Explanation

Safe AED use follows the device prompts in order: turn it on, expose and dry the chest, attach the pads, keep everyone clear during analysis, and press the shock button only if the AED instructs it. After a shock, CPR is restarted immediately unless the AED or a trained responder says otherwise. Touching the person during analysis or shock is unsafe and can interfere with the device.
