Why does a patient in shock secondary to blood loss develop​ pale, cool, and clammy​ skin?

When the body senses low blood​ volume, it diverts blood from nonvital areas to vital organs.

If you see angulation when assessing a​ patient, then:

a bone or bones are out of anatomical position.

The first step in the progression of compartment syndrome is​ that:

a fracture or crush injury causes bleeding or swelling in an extremity.

The severity of external bleeding is influenced by several​ factors, including the bleeding​ person's:

ability to clot.

All burns are to be treated as more serious​ if:

accompanied by other injuries or medical problems.

A fracture in which the broken bone segments are at an angle to each other is​ called:

an angulated fracture.

avoid your focus being distracted by the most dramatic extremity injuries.

When a flap of tissue is traumatically​ removed, this condition is called​ a(n):

avulsion

When​ crushed, the liver and​ spleen:

bleed profusely and cause shock.

Cardiac tamponade occurs​ when:

blood enters the pericardial sac surrounding the heart.

Shock is typically caused by a problem with the​ heart, fluid​ volume, or:

blood vessels.

In the case of a large​ evisceration, you should place layers​ of:

bulky dressings over a dressing moistened with saline.

Microscopically small structures in the circulatory system that supply every cell in the body​ are:

capillaries

Jugular venous distention is most likely observed​ with:

cardiac tamponade

You are caring for a​ 62-year-old male patient who complains of chest​ pain, shortness of​ breath, and nausea. His heart rate is more than​ 120, and his blood pressure is​ 90/60. You notice some pallor and peripheral cyanosis on his​ cool, clammy skin. He is most likely suffering​ from:

cardiogenic shock.

It is true that all bleeding involving external blood​ loss:

carries the risk of transmitted infection.

An internal injury with no open pathway from the outside is​ called:

closed

A fracture that results in multiple bone pieces at the fracture site is termed​ a:

comminuted fracture

When palpating a fracture site on a​ patient's mid-thigh, you notice a grating sensation. This is known​ as:

crepitus. Crepitus is a grating sensation or sound made when fractured bone ends rub together.

​Rapid, shallow​ breathing; pale,​ cool, clammy​ skin; and a low blood pressure in a patient with an abdominal injury are signs​ of:

developing shock.

To control​ bleeding, start​ with:

direct pressure and elevation.

The method of bleeding control that is the first and most successful method to try​ is:

direct pressure.

The sterile material that is placed directly on a wound is termed​ the:

dressing

Application of a cervical collar to a patient should​ happen:

during the secondary assessment.

Once a pressure dressing has been​ applied, the EMT should​ next:

ensure that bleeding is controlled.

​Generally, when providing emergency care of open​ wounds, the first thing you would do​ is:

expose the wound.

A fracture of two or more adjacent ribs in two or more places that allows for free movement of the fractured segment is called​ a:

flail chest

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 is​ a(n):

hematoma

An open wound to the​ chest, if an occlusive dressing is not​ available, should be​ sealed:

immediately with a gloved hand.

For a​ high-priority, unstable patient with musculoskeletal​ injuries, you​ should:

immobilize the whole body on a long spine board and​ "load and​ go."

Guidelines for splinting​ long-bone injuries​ include:

immobilizing the hand or foot in the position of function.

Hypoperfusion​ is:

inadequate blood flow to the tissues.

An injury to the hollow organs in the abdomen typically leads​ to:

inflammation and infection.

paradoxical motion

Bones are covered by a​ strong, white, fibrous material called​ the:

periosteum

When air is present in the chest​ cavity, the injury is called​ a:

pneumothorax

The signs and symptoms of internal bleeding​ include:

poor peripheral perfusion.

Swelling or deformity at the site of a bruise indicates​ a:

possible underlying fracture.

A primary reason for splinting a bone or joint injury​ is:

preventing movement to reduce the chance for further injury.

Burns involving the airway often lead​ to:

respiratory compromise

A​ 22-year-old female patient slipped running down​ stairs, and has injured her right tibia and fibula. You have used an air splint to splint the injury. To test the​ splint, you​ can:

see if you can cause a slight dent in the plastic with fingertip pressure.

Your patient was just involved in a motor vehicle collision. She is breathing very fast and shallowly. You auscultate her lung sounds and find diminished breath sounds on the right side. You suspect that the patient is most likely suffering​ from:

simple pneumothorax

Your patient has a nontraumatic fracture of the left wrist. Appropriate treatment would be​ to:

splint with a padded rigid splint.

Twisting force​ involves:

stretching or tearing of muscles and ligaments.

To see the effect of direct​ force, you would look​ at:

the area of the point of impact.

The first effects of a bone injury are swelling of soft tissue​ and:

the formation of a blood clot in the area of the fracture.

To realign an​ extremity, an EMT grasps the distal extremity while a partner places one hand above and one hand below the injury​ site, and​ then:

the partner supports the site while the first EMT creates gentle manual traction in the direction of the long axis of the extremity.

Burns pose greater risks to infants and children than to adults​ because:

their body surface area is greater in relation to their total body size.

In caring for an amputated​ part, it is important​ to:

wrap the part in sterile gauze and keep it cool.

In treating a puncture wound of the​ eye, if you bandage both​ eyes, it is​ because:

you want to avoid sympathetic eye movement

Internal bleeding may result from a variety of causes. If you suspect that your patient has internal​ bleeding, you should remember​ that:
