Exam 4: Vocab Flashcards
arterial bleeding
bleeding from an artery, which is characterized by bright red blood that is rapid, profuse, and difficult to control.
capillary bleeding
bleeding from capillaries, which is characterized by a slow, oozing flow of blood.
cardiogenic shock
shock, or lack of perfusion, brought on not by blood loss but by the heart’s inadequate pumping action. It is often the result of a heart attack or congestive heart failure.
compensated shock
when the patient is developing shock but the body is still able to maintain perfusion.
decompensated shock
when the body can no longer compensate for low blood volume or lack of perfusion. Late signs such as decreasing blood pressure become evident.
hemorrhage
bleeding, especially severe bleeding
hemorrhagic shock
shock resulting from blood loss
hemostatic agents
substances applied as powders, dressings, gauze, or bandages to open wounds to stop bleeding.
hypoperfusion
the body’s inability to adequately circulate blood to the body’s cells to supply them with oxygen and nutrients
hypovolemic
shock resulting from blood or fluid loss.
neurogenic shock
hypoperfusion due to nerve paralysis (some- times caused by spinal cord injuries) resulting in the dilation of blood vessels that increases the volume of the circulatory system beyond the point where it can be filled.
perfusion
the supply of oxygen to and removal of wastes from the body’s cells and tissues as a result of the flow of blood through the capillaries
pressure dressing
a bulky dressing held in position with a tightly wrapped bandage, which applies pressure to help control bleeding.
shock
the body’s inability to adequately circulate blood to the body’s cells to supply them with oxygen and nutrients, which is a life-threatening condition.
tourniquet
a device used for bleeding control that constricts all blood flow to and from an extremity.
venous bleeding
bleeding from a vein, which is characterized by dark red or maroon blood and a steady, easy-to-control flow.
abrasion
a scratch or scrape
amputation
the surgical removal or traumatic severing of a body part, usually an extremity
avulsion
the tearing away or tearing off of a piece or flap of skin or other soft tissue. This term also may be used for an eye pulled from its socket or a tooth dislodged from its socket.
bandage
any material used to hold a dressing in place
closed wound
an internal injury with no open pathway from the
outside.
contusion
a bruise
crush injury
an injury caused when force is transmitted from the body’s exterior to its internal structures. Bones can be broken; muscles, nerves, and tissues damaged; and internal organs ruptured, causing internal bleeding.
dermis
the inner (second) layer of the skin found beneath the epidermis. It is rich in blood vessels and nerves.
dressing
any material (preferably sterile) used to cover a wound that will help control bleeding and prevent additional contamination.
epidermis
the outer layer of the skin
full-thickness burn
a burn-in in which all the layers of the skin are damaged. There are usually areas that are charred black or areas that are dry and white
hematoma
a swelling caused by the collection of blood under the skin or in damaged tissues as a result of an injured or broken blood vessel.
laceration
a cut
occlusive dressing
any dressing that forms an airtight seal
open wounds
an injury in which the skin is interrupted, exposing the tissue beneath.
partial-thickness burn
a burn in which the epidermis (first layer of skin) is burned through and the dermis (second layer) is damaged. Burns of this type cause reddening, blistering, and a mottled appearance.
pressure dressing
a dressing applied tightly to control bleeding.
puncture wound
an open wound that tears through the skin and destroys underlying tissues. A penetrating puncture wound can be shallow or deep. A perforating puncture wound has both an entrance and an exit wound.
rules of nines
a method for estimating the extent of a burn. For an adult, each of the following areas represents 9 percent of the body surface: the head and neck, each upper extremity, the chest, the abdomen, the upper back, the lower back and buttocks, the front of each lower extremity, and the back of each lower extremity. The remaining 1 percent is assigned to the genital region. For an infant or child, the percentages are modified so 18 percent is assigned to the head, 14 percent to each lower extremity.
rule of palm
a method for estimating the extent of a burn. The palm and fingers of the patient’s own hand, which equals about 1 percent of the body’s surface area, is compared with the patient’s burn to estimate its size.
subcutaneous layers
the layers of fat and soft tissues found below the dermis.
superficial burn
a burn that involves only the epidermis, the outer layer of the skin. It is characterized by reddening of the skin and perhaps some swelling. A common example is a sunburn. Also called a first-degree burn.
universal dressing
a bulky dressing
evisceration
an intestine or other internal organ protruding through a wound in the abdomen
flail chest
fracture of two or more adjacent ribs in two or more places that allows for free movement of the fractured segment
paradoxical motion
movement of ribs in a flail segment that is opposite to the direction of movement of the rest of the chest cavity
pneumothorax
air in the chest cavity
sucking chest wound
an open chest wound in which air is “sucked” into the chest cavity.
tension pneumothorax
a type of pneumothorax in which air that enters the chest cavity is prevented from escaping
angulated fracture
fracture in which the broken bone segments are at an angle to each other.
