Question

Anajali is studying for her Health Science test, and she needs to remember the sequence of events that lead to cardiac arrest

Which is the correct sequence?
i. The heart beats erratically and often stops completely
ii. Ischemia progresses to an infarction.
III. Blockages occur in the right and left coronary arteries.
iv. Insufficient blood supply to the heart happens.
i, ii, iii, iv
ii, vi, i, ili
ill, iv, ii, i
iv. i. II, IN
​

Answer 1

Ill, IV, II, I

Step-by-step explanation:

Cardiac arrest is the interruption of blood circulation, resulting from the sudden and unexpected suspension of heartbeat. After a cardiorespiratory arrest, the person loses consciousness in about 10 to 15 seconds due to the cerebral blood circulation arrest. If a person remains 4 to 6 minutes without oxygen, brain cells die quickly.

The heartbeat causes blood to circulate throughout the body. When the heart does not function properly or stops, the blood that carries oxygen and nutrients does not reach the tissues and organs, causing vital organs such as the heart and lung to stop functioning due to lack of energy.

The events that lead to cardiac arrest are:

• The heart beats erratically and often stops completely
• Ischemia progresses to an infarction.
• Blockages occur in the right and left coronary arteries.
• Insufficient blood supply to the heart happens.

Answer 2

Answer: Option C

Step-by-step explanation:

The correct sequence which can be used to remember the sequence is as follows.

The people who tend to eat more oily food or cholesterol rich food is more prone to heart attack or cardiac arrest. Blockage occurs in the right and left coronary artery.

Because of the blockage there is a chance of insufficient blood supply in the heart. Ischemia pain starts in the heart due to inadequate oxygen supply.

Then finally the heart beat erraticates and may stop turning into cardiac arrest.
