WEST COAST EMT BLOCK 4 EXAM QUESTIONS AND ANSWERS 2025
What is cavitation? - (ANSWER)A phenomenon in which speed causes a bullet to generate pressure
waves, which cause damage distant from the bullet's path.
What is Newton's first law? - (ANSWER)An object at rest stays at rest and an object in motion stays in
motion with the same speed and in the same direction unless acted upon by an unbalanced force.
What is potential energy? - (ANSWER)The product of mass (weight), force of gravity (acceleration), and
height.
- Energy that is stored.
PE = mgh
What is kinetic energy? - (ANSWER)The energy of motion or movement
KE = ½ mass x velocity^2 or KE = ½ mv^2
What is a vehicle collision? - (ANSWER)i. Damage to the car does not directly affect patient care but
does provide information about the severity of the collision.
ii. By assessing the vehicle that has crashed, you can often determine the MOI.
What is a human collision? - (ANSWER)- Kinetic energy produced by the passenger's mass and velocity is
converted into the work of stopping his or her body.
- Common passenger injuries include lower extremity fractures, rib fractures, and head trauma.
What is an internal collision? - (ANSWER)i. Internal injuries may not be as obvious as external injuries,
but they are often the most life threatening.
What do we assume with the death of an occupant in the same vehicle as another person? -
(ANSWER)Assume major injury because the force was strong enough to kill the other passenger.

What is the purpose of airbags? - (ANSWER)To reduce blunt chest trauma.
What happens if the airbags do not deploy and what should you do? - (ANSWER)Decrease the severity
of deceleration injuries and decrease injury to the chest, face and head. If it does not deploy, disconnect
the vehicle battery.
What is the purpose of a head rest and what does it prevent? - (ANSWER)To reduce the rearward
motion of the head in a rear end crash and decrease the chances of occupants sustaining whiplash neck
injuries.
What are arteries? - (ANSWER)Blood vessels that carry blood away from the heart
What are arterioles? - (ANSWER)The smallest branches of arteries leading to the vast network of
capillaries.
What are capillaries? - (ANSWER)Links between the arterial and venial sides of vessels, also where gas
exchange occurs.
What are venules? - (ANSWER)small veins that receive blood from the capillaries.
What are veins? - (ANSWER)Blood vessels that carry blood back to the heart.
What affects the ability of the blood to clot? - (ANSWER)the type of vessel that is broken (arterial vessels
clot slower than venous and capillary vessels)
patients with hemophilia: lacks one or more of the blood's clotting factors and bleeding may occur
spontaneously
certains medications can affect the ability of the blood to clot
warfarin, anti-coagulants, antiplatelets (Aspirin)
