Explanation

For acute tissue injuries such as sprains and strains, cryotherapy (cold application) is recommended during the first 24–48 hours.

Cold therapy:

• Reduces swelling and inflammation

• Decreases pain

• Limits tissue damage

Less effective than heat initially → heat is avoided early
Only useful for pain relief → also reduces swelling and inflammation
Contraindicated for burns → this option is irrelevant to sprains

Explanation

A Class C fire involves energized electrical equipment.

The extinguisher used must not conduct electricity.

• Carbon Dioxide (CO₂) → safe for electrical fires, leaves no residue

• Dry Powder → non-conductive and effective on electrical fires

Water based → conducts electricity (dangerous)
Wet chemical → used mainly for Class K (kitchen) fires
Foam based → may conduct electricity

Explanation

The aims of first aid are to:  

- Preserve life  

- Prevent further injury  

- Promote recovery  

- Relieve pain  

- Arrange early transport to medical facility  

Treating on spot immediately is not always the goal—especially if the situation is unstable or professional care is required.

The focus is on stabilizing the patient until expert help is available.

Explanation

CPR (Cardiopulmonary Resuscitation) is the emergency procedure that combines:

- Artificial circulation (chest compressions)  

- Artificial ventilation (rescue breaths)

It is used to maintain blood flow and oxygenation in a person who has gone into cardiac arrest.

Explanation

 Wash with clean water thoroughly.

The immediate first aid for chemical splash in the eye is:

- Irrigate the eye with clean, running water for at least 15–20 minutes.

- This helps to flush out the chemical and minimize damage.

Explanation

Placing a head injury patient with the head side down can increase intracranial pressure, which is dangerous.

Correct first aid steps for suspected head injury:

- Secure the airway (B)

- Roll to side only if vomiting or airway compromise is suspected (A)

- Keep head slightly elevated (D) to reduce intracranial pressure and improve venous return

Explanation

The most effective immediate first aid for burns is to cool the burn with running water (preferably cool, not ice-cold) for at least 10-20 minutes.

This helps:

- Reduce skin temperature  

- Prevent burn progression  

- Relieve pain

Explanation

The first aid for epistaxis (nosebleed) includes:

- Sitting upright and leaning slightly forward

- Pinching the soft part of the nose for 5–10 minutes

- Applying a cold compress on the nose or forehead may help, but pinching the nose is the most effective method to stop bleeding.
