Shock

Question 1

Shock

Answer 1

Inadequate tissue and organ perfusion because of decreased blood volume/ circulatory stagnation

Question 2

Compensatory mechanisms

Stages of shock

Answer 2

Sympathetic NS, renin-angiotensin-aldosterone system activated

Maintain homeostasis

Question 3

Progressive stage

Stages of shock

Answer 3

Compensatory mechanisms fail, tissue becomes hypoxic, cells switch to anaerobic metabolism, lactic acid accumulates, metabolic acidosis develops

Question 4

Irreversible

Stages of shock

Answer 4

Organ damage occurs

Question 5

Neurogenic shock

Distributive shock

Answer 5

Loss of vascular sympathetic tone/ autonomic function (massive vasodilation)

Question 6

Distributive shock

Answer 6

Vasodilation causes hypovalemia

Question 7

Septic shock

Distributive shock

Answer 7

Bacterial endotoxins activate an immune reaction

Question 8

Anaphylactic shock

Distributive shock

Answer 8

Excessive allergic reaction

Question 9

Cardiogenic shock

Massive heart attack

Answer 9

Left ventricle cannot maintain adequate cardiac output

Question 10

Hypovolemic shock

Not replacing lost fluids

Answer 10

Venous return reduced due to external blood volume loss; most common type of shock

Question 11

manifestations of shock

Answer 11

Elevated lactate level (waste buildup)
Tachycardia
Tachypnea

Question 12

Shock treatment

Answer 12

Rapid fluid replacement
