6

bleeding type - bright red, spurting blood from a wound that usually indicated a severed or damaged artery

arterial bleeding

7

bleeding type - dark red blood that flows steadily from a wound that usually indicates a severed or damaged vein

venous bleeding

8

bleeding type - slowly oozing blood that is dark or intermediate color of red that usually indicates damaged capillaries

capillary bleeding

9

two types of homeostatic agents:

dressing or powder

10

Epistaxis

Nosebleed

11

The two most common sources of internal bleeding are ________ or ______.

Injured or damaged internal organs and fractured extremities, especially femur and pelvis

12

Factors that may interfere with the clotting process and lead to an increase in the rate of bleeding or the amount of blood lost:

Movement

Low body temp

Medications

Intravenous fluids

Removal of dressings and bandages

13

a wound in which there is no break in the continuity of the skin is called a _______.

closed injury

14

an injury to the tissue and blood vessels contained within the dermis; or bruise.

contusion

15

black and blue discoloration associated with a contusion that occurs when the red blood cells in the blood that has leaked out of the capillary or vessel become deoxygenated

ecchymosis

16

a closed injury to the soft tissues characterized by swelling and discoloration caused by a mass of blood beneath the epidermis.

hematoma

17

an open or closed injury in which high-pressure forces cause serious damage to underlying soft tissues with internal bleeding, resulting in possible hemorrhagic shock

crush injury

18

an injury in which the continuity of the skin is broken.

open injury

19

6 general types of open injuries:

abrasions, lacerations, avulsions, amputations, penetrations/punctures, and crash injuries.

20

an open injury to the outermost layer of the skin caused by a scraping away, rubbing, or shearing away of the tissue.

abrasion

21

an open injury characterized by a loose flap of skin and soft tissue that has been torn loose or pulled completely off.

avulsion

22

an open injury caused by the ripping or tearing away of a limb, body part, or organ.

amputation

23

an open injury usually caused by forceful impact with a sharp object and characterized by a wound whose edges may be linear (smooth and regular) or stellate (jagged and irregular) in appearance; a wound that penetrates the brain

laceration

24

an open injury caused by a sharp, pointed object being pushed into the soft tissues

penetration/punctures

25

an injury in which a part of the body is caught or strangled by some piece of machinery

clamping injury

26

an air- and water-tight trauma dressing used in first aid. These dressings are generally made with a waxy coating so as to provide a total seal, and as a result do not have the absorbent properties of gauze pads.

occlusive dressing

27

a protrusion of organs from a wound

evisceration
