Shock

Question 1

Decreased intravascular volume.
Increased HR early, drop in BP later. Increased RR. 
Anxious, restless, confused.
Cool, clammy, poor turgur, cyanotic.
Poor urine output

Answer 1

Hypovolemic

Question 2

Blood volume inappropriately distributed in peripheral vascular system–>relative hypovolemia and decreased perfusion.
Septic, anaphylactic and neurogenic.
Decreased BP, normal or low HR. Warm skin. Hyperdynamic heart sounds, wide pulse pressure

Answer 2

Distributive

Question 3

Impaired cardiac output from physical obstruction of blood flow (tamponade, tension pneumo, PE)
Elevated central venous pressure.

Answer 3

Obstructive

Question 4

Pump failure (contractility, arrhythmia, structural)
Greatly increased HR, JVP, AMS, cool extremities

Answer 4

Cardiogenic
