Bleeding

Question 1

What is the definition of hemorrhage?

Answer 1

Bleeding

Hemorrhage refers to the loss of blood from the circulatory system.

Question 2

What are the two types of bleeding?

Answer 2

• External
• Internal

Understanding the type of bleeding is crucial for assessment and management.

Question 3

What are the three parts of the cardiovascular system?

Answer 3

• Pump (heart)
• Container (blood vessels)
• Fluid (blood and body fluids)

These components work together to circulate blood throughout the body.

Question 4

What is the role of the heart in the cardiovascular system?

Answer 4

Circulates blood as two paired pumps

The heart consists of upper chambers (atria) and lower chambers (ventricles).

Question 5

What do arteries do?

Answer 5

Carry blood away from the heart

Arteries are crucial for delivering oxygenated blood to tissues.

Question 6

What is the function of capillaries?

Answer 6

Link arterioles and venules, allowing exchange of oxygen, nutrients, and waste

Capillaries facilitate the transfer of substances between blood and tissues.

Question 7

What are the components of blood?

Answer 7

• Red blood cells
• White blood cells
• Platelets
• Plasma

Each component has a specific function, such as oxygen transport and immune response.

Question 8

What is the significance of external bleeding?

Answer 8

Visible hemorrhage that can lead to serious complications

It is important to assess and manage external bleeding promptly.

Question 9

What are the characteristics of arterial bleeding?

Answer 9

• Bright red
• Spurts with pulse
• Difficult to control

Arterial bleeding is often more severe and requires immediate intervention.

Question 10

What is hypovolemic shock?

Answer 10

A condition that can develop from significant blood loss

It is characterized by inadequate perfusion to the body’s organs.

Question 11

What are the signs and symptoms of internal bleeding?

Answer 11

• Pain
• Swelling
• Distention
• Dyspnea
• Tachycardia
• Hypotension

Internal bleeding can be difficult to detect and requires careful assessment.

Question 12

What does DCAP-BTLS stand for?

Answer 12

• Deformities
• Contusions
• Abrasions
• Punctures/penetrations
• Burns
• Tenderness
• Lacerations
• Swelling

This acronym is used to assess injuries during the secondary assessment.

Question 13

What is the primary assessment in emergency care?

Answer 13

Identifying life threats and assessing the patient’s condition

It includes evaluating airway, breathing, circulation, and any immediate threats.

Question 14

What is the most common method to control external bleeding?

Answer 14

Direct pressure

Applying pressure helps to stop blood flow and allows for normal clotting.

Question 15

What is a tourniquet used for?

Answer 15

To control substantial bleeding from an extremity injury

Tourniquets should only be used when direct pressure is ineffective.

Question 16

What are hemostatic agents?

Answer 16

Gauze impregnated with a chemical compound that promotes clot formation

They are used when direct pressure is inadequate for controlling bleeding.

Question 17

What is the role of the autonomic nervous system in bleeding?

Answer 17

Monitors the body’s needs and adjusts blood flow

It helps maintain homeostasis and perfusion during emergencies.

Question 18

What should be done if a patient has obvious, life-threatening external bleeding?

Answer 18

Control it as quickly as possible

Immediate action is crucial to prevent further blood loss.

Question 19

What is the transport decision based on?

Answer 19

Assessment of XABCs and life threats

Signs indicating the need for rapid transport include tachycardia, low blood pressure, and clammy skin.

Question 20

What are the types of splints mentioned?

Answer 20

• Air splints
• Soft splints or pressure splints
• Pelvic binder

Each type serves specific purposes in controlling bleeding and immobilizing fractures.

Question 21

Air splints can be used to control bleeding because they act as a _______.

Answer 21

pressure bandage

They are not as effective as tourniquets and should not replace them when indicated.

Question 22

What conditions can cause bleeding from the nose, ears, and mouth?

Answer 22

• Skull fracture
• Facial injuries
• Sinusitis
• High blood pressure
• Coagulation disorders
• Digital trauma
• Cancer

These conditions can lead to epistaxis or other forms of bleeding.

Question 23

True or false: Epistaxis can occasionally cause enough blood loss to send a patient into shock.

Answer 23

TRUE

Epistaxis is a common emergency that can lead to significant blood loss.

Question 24

What does it look like if cerebrospinal fluid is present in blood or drainage?

Answer 24

A target or halo-shaped stain may occur on the dressing

This indicates the presence of cerebrospinal fluid.

Question 25

What is the **most accurate definition of perfusion**?

Answer 25

circulation of blood within an organ with sufficient amounts of oxygen ## Footnote Perfusion is crucial for delivering oxygen and nutrients to tissues.

Question 26

Which injury has the **HIGHEST treatment priority** in a motorcycle crash?

Answer 26

1-inch laceration to the thigh with spurting, bright red blood ## Footnote This type of bleeding is life-threatening and requires immediate attention.

Question 27

When caring for a patient with internal bleeding, the EMT must first take appropriate _______.

Answer 27

standard precautions ## Footnote This is essential before providing any patient care.

Question 28

The quickest and **MOST effective way to control external bleeding** from an extremity is:

Answer 28

direct pressure and elevation ## Footnote This method is effective in most cases of external bleeding.

Question 29

When applying a tourniquet to an amputated arm, the EMT should avoid applying it over a _______.

Answer 29

joint ## Footnote The tourniquet should be applied using the widest bandage possible.

Question 30

What is the **MOST likely contributing factor** to a 70-year-old man's severe nosebleed?

Answer 30

His blood pressure ## Footnote A BP of 180/100 indicates significant pressure, likely causing the epistaxis.

Question 31

When caring for a patient with severe epistaxis, the MOST effective way to prevent aspiration of blood is to _______.

Answer 31

tilt the patient’s head forward while he or she is leaning forward ## Footnote This position helps prevent blood from trickling down the throat.

Question 32

Controlling internal bleeding usually requires _______.

Answer 32

surgery in a hospital ## Footnote Field care includes administering high-flow oxygen and monitoring vital signs.

Question 33

Define **external bleeding**.

Answer 33

Blood loss that occurs outside the body, usually from a visible wound.

Question 34

True or false: **Internal bleeding** is always visible externally.

Answer 34

FALSE ## Footnote Internal bleeding may occur in organs or cavities without visible wounds.

Question 35

What is a common sign of **internal bleeding**?

Answer 35

Signs include abdominal pain, swelling, or bruising.

Question 36

Fill in the blank: **Capillary bleeding** is characterized by _______ blood flow.

Answer 36

slow and oozing

Question 37

What should you assess for in **external bleeding**?

Answer 37
