Caused by inadequate function of heart

Question 3

Answer 3

Pulmonary edema

Question 4

What is obstructive shock

Answer 4

• Obstructive shock occurs when conditions that cause mechanical obstruction of the cardiac muscle also affect the pump function
• Common examples include cardiac tamponade and tension pneumothorax.

Question 5

What is tension pnumothorax and what is it caused by?

Answer 5

Air getting in chest

Caused by damage to lung tissue

Question 6

What is cardiac tamponade and what is it caused by?

Answer 6

Collection of fluid between the pericardial sac and the myocardium

Caused by blunt or penetrating trauma

Question 7

What does distributed shock cause?

Answer 7

Widespread dilation of blood vessels

Question 8

What is septic shock and what can it cause?

Answer 8

Toxins damage vessel walls which leads to an infection

Can cause life‑threatening low blood pressure

Question 9

What is neurogenic shock

Answer 9

–Usually a result of injury to the part of the nervous system that controls the size and muscle tone of the blood vessels
–Causes include damage to the spinal cord, brain conditions, tumors, pressure on the spinal cord, and spina bifida.

Question 10

What is anaphylaxis shock

Answer 10

–Occurs when a person reacts violently to a substance to which he or she has been sensitized
–Sensitization means becoming sensitive to a substance that did not initially cause a reaction.
–Each subsequent exposure tends to produce a more severe reaction.

Answer 15

–Compensated shock: early stage when the body can still compensate for blood loss
–Decompensated shock: late stage when blood pressure falls
–Irreversible shock: terminal stage when transfusion is not enough to save patient

Question 16

Answer 16

Blood pressure

Question 17
