Two Causes of Hypovolemic Shock

Answer 2

Hemorrhagic and Lack of Fluid Volume

Question 3

What is Cardiogenic Shock?

Answer 3

Shock caused by inadequate pumping action of the heart as a result of myocardial abnormalities

Four Types of Cardiogenic Shock are?

Answer 4

Myocardial infarction
Myocardial Contusion
Dysrhythmias
Congestive Heart Failure

Question 5

What type of disease can lead to dysrhythmias?

Answer 5

Hypoxia

Question 6

What is Distributive shock?

Answer 6

Shock due to widespread vasodilation

Question 7

What are the causes of Distributive shock?

Answer 7

Anaphylactic shock
Septic Shock
Overdose
Psychogenic Shock
Neurogenic Shock

Question 8

What are the two types of shock?

Answer 8

Compensated Shock and Decompensated shock

Question 9

Which type of shock is considered “Late Shock”

Answer 9

Decompensated Shock

Question 10

What is considered “Early Shock”

Answer 10

Compensated shock

Question 11

What are signs of decompensated shock?

Answer 11

Ashen, Mottled, or cyanotic skin
Dull eyes
Labored or irregular breathing
Falling BP

Question 12

What is Septic Shock?

Answer 12

Due to severe infections, usually bacteria, the toxins damage the vessel walls causing increased vascular permeability which causes walls to leak and not contract.

Question 13

What is Neurogenic Shock?

Answer 13

Damage to the spinal cord at the cervical levels causes significant injury to the Nervous system that controls size and muscular tone of blood vessels.

Question 14

What is Anaphylactic Shock?

Answer 14

Occurs when a person reacts violently to a substance to which he or she has been sensitized.

Question 15

Skin signs of anaphylactic shock

Answer 15

Flushing, itching, burning over the face and upper part of the chest.
Edema of the face tongue and lips
Pallor skin
Cyanosis around the lips

Question 16

You suspect your patient is in shock. You note the patient’s skin is pale. This is likely due to ___________.
A. peripheral vasoconstriction
B. peripheral vasodilation
C. an increased heart rate
D. hypothermia

Answer 16

A. peripheral vasoconstriction

Question 17

Pulmonary edema and impaired ventilation occur during:
A. anaphylactic shock.
B. cardiogenic shock.
C. septic shock.
D. neurogenic shock

Answer 17

B. cardiogenic shock

Question 18

Your patient is in shock, but the body’s defense mechanisms are currently able to maintain adequate circulation. This is called ___________.
A. irreversible shock
B. late shock
C. compensated shock
D. decompensated shock

Answer 18

C. compensated shock

Question 19

A. the brain.
B. the heart.
C. the skin.
D. the lungs.

Answer 19

C. the skin.

B. Open the airway.
C. Check for a pulse.
D. Administer oxygen.

Answer 21

A. Control the bleeding

Question 22

Your patient has a decreased cardiac output and poor myocardial contractility. This will likely lead to ___________.
A. hypovolemic shock
B. cardiogenic shock
C. septic shock
D. neurogenic shock

Answer 22

B. cardiogenic shock

Question 23

Foods, medications, and insects are common causes of ________.
A. septic shock
B. anaphylactic shock
C. neurogenic shock
D. psychogenic shock

Answer 23

B. anaphylactic shock

Question 24

A. severe infection
B. anaphylaxis
C. ischemic stroke
D. Spinal injury

Answer 24

C. ischemic stroke

Question 25

Distributive shock occurs when
A. severe bleeding causes tachycardia in order to distribute blood to the organs faster
B. temporary but severe vasodilation causes a decrease in blood supply to the brain
C. widespread dilation of the blood vessels causes blood to pool in the vascular beds
D. an injury causes restriction of the heart muscle and impairs its pumping function

Answer 25

C. widespread dilation of the blood vessels causes blood to pool in the vascular beds

Question 26

What is Distributive shock?

Answer 26

Shock due to widespread vasodilation

Question 27

Neurogenic shock occurs when:
A. failure of the nervous system causes widespread vasodilation.
B. the spinal cord is severed and causes massive hemorrhaging.
C. there is too much blood to fill a smaller vascular container.
D. massive vasoconstriction occurs distal to a spinal cord injury.

Answer 27

A. failure of the nervous system causes widespread vasodilation.

Question 28
