Respiratory emergency

when the body’s vital organs are no longer receiving oxygen-rich blood. How many minutes without oxygen the brain damage will occur?

• 0-4 minutes

• 4-6 minutes

• 6-10 minutes

• after 10 minues

Answer explanation

The brain can suffer damage after 4-6 minutes without oxygen. This is because brain cells are highly sensitive to oxygen deprivation, leading to irreversible damage if blood flow is not restored within this timeframe.

A Lay Responder must perform how rescues breath during CPr?

• 5 cycles

• 2 times

• 30 compression

• none of the choices

Answer explanation

A Lay Responder performs 30 chest compressions followed by 2 rescue breaths. The question's options do not accurately reflect this, making 'none of the choices' the correct answer.

During respiratory arrest, which part of the chest should you place the heel of your palm?

• xiphoid process

• Sternum

• rib cage

• none of the choices

Answer explanation

During respiratory arrest, chest compressions should be performed on the sternum, not the xiphoid process or rib cage. However, since the question asks for the heel of the palm placement, 'none of the choices' is correct.

30 chest compressions in about 18 seconds (at least 100 compressions per minute)

• True

• Flase

Answer explanation

The statement is true because performing 30 chest compressions in about 18 seconds meets the guideline of at least 100 compressions per minute, which is essential for effective CPR.

DO NOT STOP: Continue cycles of CPR. Do not stop except in one of these situations:

• You find an obvious sign of life, such as breathing.

• Another trained responder or EMS personnel take over.

• You are too exhausted to continue.

• all of the choices

Answer explanation

The correct answer is 'all of the choices' because CPR should only be stopped if there are signs of life, another trained responder takes over, or if you are too exhausted to continue.

Which is the purpose of CPR?

• To keep a person’s airway open

• To identify any immediate threats to life

• To supply the vital organs with blood containing oxygen

• All of the choices

Answer explanation

The primary purpose of CPR is to supply vital organs with blood containing oxygen, which is crucial for survival during cardiac arrest. While keeping the airway open and identifying threats are important, they support this main goal.

What is the main function of the respiratory system?

• to provide oxygen and remove carbon dioxide from the body

• to bring oxygen to the body

• to break down food and absorb nutrients

• to remove oxygen from the body and deliver carbon dioxide

Answer explanation

The main function of the respiratory system is to provide oxygen to the body and remove carbon dioxide, which is essential for cellular respiration and maintaining pH balance, making the first answer choice correct.

What are the main organs of gas exchange in the respiratory system?

• diapragm

• lungs

• trachea

• bronchi

Answer explanation

The main organs of gas exchange in the respiratory system are the lungs. They facilitate the transfer of oxygen and carbon dioxide between the air and the bloodstream, unlike the diaphragm, trachea, and bronchi, which support the process.

Inhale!!!!
Your lungs are ___________  air

• taking in

• letting out

Answer explanation

Inhale means to breathe in. Therefore, your lungs are 'taking in' air, which is the correct choice. 'Letting out' would refer to exhaling, not inhaling.

EXHALE!!!
My lungs are __________________ air. 

• taking in

• letting out

Answer explanation

The phrase 'EXHALE!!!' indicates that the action is about releasing air. Therefore, the correct choice is 'letting out' air, as it directly relates to the act of exhaling.
