What is the primary risk associated with bleeding?

• Infection

What is the primary danger of choking?

• Damage to the throat

• Obstruction of the airway, preventing breathing

Hyperventilation typically causes a decrease in:

• Oxygen levels

• Blood pressure

• Carbon dioxide levels

• Heart rate

What is the primary cause of a heart attack?

• A blockage of a blood vessel in the brain

• A ruptured blood vessel in the heart

• A blood clot blocking blood flow to part of the heart

What is the main difference between an ischemic stroke and a hemorrhagic stroke?

• Ischemic stroke is caused by a ruptured blood vessel; hemorrhagic stroke is caused by a blockage

• Ischemic stroke is caused by a blockage; hemorrhagic stroke is caused by a ruptured blood vessel

• Ischemic stroke affects the lungs; hemorrhagic stroke affects the heart
