Q

The smallest branches of arteries leading to the vast network of capillaries

A

Arterioles

158
Q

Blood in the urine

A

Hematuria

159
Q

A condition in which blood volume, due to massive internal or external bleeding or extensive loss of body water, results in inadequate perfusion

A

Hypovolemic shock

160
Q

A device that provides proximal compression of severe bleeding near the axial or inguinal junction with the torso

A

Junctional tourniquet

161
Q

A build up of blood beneath the skin that produces a characteristic blue or black discoloration as the result of an injury; also see contusion

A

Ecchymosis

162
Q

A condition in which the circulatory system fails to provide sufficient circulation to maintain normal cellular functions; also called shock

A

Hypoperfusion

163
Q

The circulation of blood in adequate amounts to meet cells’ current needs for oxygen, nutrients, and waste removal.

A

Perfusion

164
Q

Always ask patient if he/she takes blood ______________ medications; ie: …

A

(Thinner) Aspirin, warfarin

165
Q

A device to splint the bony pelvis to reduce hemorrhage from bone ends, venous disruption, and pain.

A

Pelvic binder

166
Q

The narrowing of a blood vessel, such as with ________perfusion or cold extremities

A

(Hypoperfusion) vasoconstriction

167
Q

A phenomenon in which speed causes a bullet to generate pressure waves, which cause damage distant from the bullet’s path.

A

Cavitation

168
Q

The measure of force over distance

A

Work

169
Q

Kinetic Energy = 1/2 _____(wt) x velocity (_______) or KE = 1/2 __ x V 2

A

1/2 mass (weight) x velocity2 or KE = 1/2 M x V2

The energy of a moving object is called kinetic energy. Reflects the relationship between the mass (weight) of the object and the velocity (speed) at which it is traveling.

170
Q

A product of mass (weight), force of gravity, and height and is mostly associated with the energy of falling objects.

A

Potential energy

171
Q

For every action there is an equal and opposite reaction

A

Newton’s Third Law . You push door, door pushes back (reacts)

172
Q

Force equals mass x acceleration F = M x A acceleration is the change in velocity (speed) that occurs over time

A

Newton’s Second Law. Not so much that speed kills. Change in velocity with respect to time generates the forces that cause injury

173
Q

States that objects at rest tend to stay at rest. And objects that are in motion _____ to _____ in ______ . Unless acted on by some force.

A

Newton’s First Law. “…stay in motion.”
