Formative Practice 2.1 – Form 4 Science (KSSM) Chapter 2


Question 1:
Explain the meaning of cardiopulmonary resuscitation (CPR).

Answer:
An emergency aid that involves a combination of chest compressions and breathing into the mouth of the victim.


Question 2:
Give three situations that cause breathing or the heartbeat to stop.

Answer:
• Heart attack
• Electric shock
• Lightning strike
• Drowning
(any three)


Question 3:
Muthu and his father were watching television at home when his father had a heart attack and became unconscious. Can Muthu perform CPR on his father? Explain your answer.

Answer:
Yes, he can. Chest compression technique is the most suitable method for someone who has a heart attack.
This method is carried out to restore blood circulation artificially by pumping blood through the heart. Muthu’s dad will survive if the flow of blood continues in his body.


Question 4:
If you have never learned the correct way of performing chest compressions, can you carry out this method on a victim who needs emergency help? What could you do to help?

Answer:
No. This is because if the wrong technique is used, the victim may be injured. The correct way to help the victim is to check the victim’s response, shout ‘help’, call 999 and wait until the victim gets emergency treatment.
