Shock

Question 1

This condition is defined as a circulatory insufficiency that creates an imbalance between tissue oxygen supply and demand resulting in global tissue hypo perfusion.

Answer 1

shock

Question 2

what are the four categories of shock

Answer 2

hypovolemic
caridiogenic
disruptive
obstructive

Question 3

what type of shock is caused by decreased intravascular volume secondary to blood loss or loss of fluid and electrolytes

Answer 3

hypovolemic shock

Question 4

etiologies of hypovolemic shock

Answer 4

trauma
hemorrhage
GI bleed
burns
vomiting or diarrhea
excessive sweating
hypersolomar states

Question 5

physical findings of hypovolemic shock

Answer 5

tachy into Brady
hypotensive
Mental status changes
oliguria
cool extremities
weak pulse
LOW JVP

Question 6

fluid replacement formula for hypovolemic shock

Answer 6

LR 1-2 L bolus
PRBC, FFP, Plateletes for transfusion

for every 1 PRBC, hematocrit should increase by 3%

Question 7

meds for hypovolemic shock

Answer 7

vasopressors
epi
dopamine

Question 8

this type of shock is pump failure secondary to AMI, cardiac contusion, arrhythmia, valvular incompetence or stenosis

Answer 8

Cardiogenic

Question 9

physical findings of cariogenic shock

Answer 9

hypo
mental status change
elevated JVP
JVD
pulmonary edema
irregular pulse if arrythmia

Question 10

treatment for cardiogenic shock

Answer 10

ACLS if in cardiac arrest
small fluid challenges
vasopressors (epi, dopamine, dobutamine)

Question 11

What type of shock causes a reduction in systemic vascular resistance (sepsis, anaphylaxis, neurogenic)

Answer 11

distributive shock

Question 12

what is a type of distributive shock that is an overwhelming infection with a massive release of bacterial endotoxins causing inability to maintain perfusion

Answer 12

sepsis

Question 13

physical findings of sepsis

Answer 13

evidence of infection
elevated WBC

Question 14

physical findings of anaphylactic shock?

Answer 14

diffuse urticaria, angioedema, bronchospasm, SOB, fullness of the throat, hoarseness

Question 15

this type of distributive shock will present will with evidence of acute traumatic spinal cord injury and hypotension w/o compensatory tachy. Brady. warm, dry skin

Answer 15

neurogenic shock

Question 16

treatment for sepsis

Answer 16

ABC, 02, IV monitor
broad spectrum antibiotics

Question 17

treatment for anaphylaxis

Answer 17

ABC, 02, IV, monitor

Epinephrine
IV
Ancillary treatments (Benadryl, Zantac, Solumedrol)

Question 18

treatment for neurogenic shock

Answer 18

ABCDE (primary trauma survey to include a neuro exam)

Question 19

This type of shock is caused mostly due to extra cardiac causes of cardiac pump failure and often associated with poor right ventricle output

Answer 19

obstructive

Question 20

examples of obstructive shock

Answer 20

Massive PE, tension pneumothorax, pericardial tamponade, restrictive cardiomyopathy, abdominal compartment syndrome
