Chapter 26 Emt Basic Key Terms Quiz

Perfusion specifically refers to the flow of blood through the capillaries to supply oxygen and remove wastes from cells. The other options refer to different physiological processes.

Hypoperfusion refers to the inadequate circulation of blood, leading to a reduction in the supply of oxygen and nutrients to the body's cells. This can result in serious health consequences, such as shock, if not addressed promptly.

Shock in a medical context refers to a serious condition where the body is unable to circulate enough blood to vital organs, leading to a life-threatening situation.

A hemorrhage refers to the abnormal internal or external bleeding, typically due to a rupture of blood vessels.

Arterial bleeding is a serious type of bleeding that can result in rapid blood loss and requires immediate medical attention. Understanding the characteristics of different types of bleeding is crucial for providing appropriate first aid and seeking timely medical help.

Venous bleeding refers to bleeding from a vein, which usually results in dark red or maroon blood flowing steadily from the wound. It is relatively easy to control compared to arterial bleeding, capillary bleeding, or lymphatic vessel bleeding.

Capillary bleeding refers to bleeding from tiny blood vessels called capillaries, which have thin walls allowing blood to seep out slowly. The other incorrect answers describe bleeding from different types of blood vessels with distinct characteristics as a way to differentiate them from capillary bleeding.

A pressure dressing is specifically designed to apply pressure to help control bleeding and is held in position with a tightly wrapped bandage, unlike the other incorrect options.

A tourniquet is a medical device used to control severe bleeding by constricting blood flow to a limb. It is not related to pastries, measuring distance, or musical instruments.

Pressure points are specific areas on the body that can be used to manipulate the body's natural energies to heal and alleviate pain.

The Brachial Artery is a major artery located in the upper arm, commonly used to check the pulse in babies. It is not a vein in the leg, a bone in the foot, or an artery in the brain.

The Femoral Artery is the major artery supplying blood to the thigh, not to the arm, head, or abdomen.

Compensated shock occurs when the body is still able to maintain perfusion despite the development of shock symptoms, allowing for compensation mechanisms to keep vital organs supplied with blood and oxygen.

Hemorrhagic shock specifically refers to shock that is caused by significant blood loss, leading to inadequate perfusion of tissues and organs.

Cardiogenic shock is specifically related to the heart's pumping action, not blood loss, allergies, or immune system responses.

Neurogenic Shock is a type of shock caused by nerve paralysis and circulatory system dysfunction, not by a brain signaling issue, an allergic reaction, or increased brain activity.

Decompensated shock is a critical stage where the body's compensatory mechanisms are overwhelmed, leading to visible signs such as decreasing blood pressure.

Irreversible shock is a critical condition where the body is unable to restore perfusion to vital organs, leading to organ failure and potential death even if vital signs temporarily improve.
