shock

Question 1

hypovolemic shock

Answer 1

lack of circulating volume: gunshot wound

Question 2

cardiogenic shock

Answer 2

failure of central pump

Question 3

distributive shock

Answer 3

maldistribution of oxygen to the periphery: vasodilation and pooling in extremities, nuerogenic, septic, anaphylaxis

Question 4

obstructive shock

Answer 4

obstruction of blood into or out of the ventricles (PE, pericardial tamponade, tension pneumothorax, aortic stenosis, pregnancy, excessive PEEP)

Question 5

Sympathetic Nervous system

Answer 5

Adrenergic (fight or flight)

Question 6

Alpha receptors in sympathetic system

Answer 6

all over body:in sympathetic nervous system these vaso constrict, cause glucogeonolysis and diaphoresis.

Question 7

Alpha receptors in parasympathetic system

Answer 7

(cholinergic) vasodialate, gluconeogenesis

Question 8

Beta one receptors in sympathetic

Answer 8

In Heart: increast HR, increase contractility, increase automaticity

Question 9

Beta one receptors in parasympathetic

Answer 9

In heart (cholinergic) decrease HR, decrease contractility, decrease automaticity

Question 10

Beta two receptors in sympathetic

Answer 10

In Lungs: increase RR, bronchodilation

Question 11

Beta two receptors in parasympathetic

Answer 11

In Lungs: decrease RR, bronchoconstriction

Question 12

agonist

Answer 12

stimulates a system

Question 13

antagonist

Answer 13

diminishes the response of a system

Question 14

how would an alpha-adrenergic agonisst affect the BP?

Answer 14

Increase BP

Question 15

How would a Beta blocker affect RR?

Answer 15

decrease

Question 16

Signs/symptoms of late shock

Answer 16

Vasodilation, increased capillary permeability, increased coagulation

Question 17

mentation in early (hyperdynamic) vs late (hypodynamic)shock

Answer 17

early: Malaise, tired, restless
late: LOC, stupor, coma

Question 18

skin in early (hyperdynamic) vs late (hypodynamic)shock

Answer 18

early: warm, flushed, dry
late: cold, clammy, pale, mottled

Question 19

HR in early (hyperdynamic) vs late (hypodynamic)shock

Answer 19

early: tachy, full and bounding pulse
late: tachy, weak and thready pulse

Question 20

Respiratory rate in early (hyperdynamic) vs late (hypodynamic)shock

Answer 20

early: > 20/min
late: shallow and fast

Question 21

acid-base values in early (hyperdynamic) vs late (hypodynamic)shock

Answer 21

early: respiratory alkalosis (alveolar hyperventilation)
late: combined respiratory and metabolic acidosis

Question 22

only Blood product not needing ABO compatibility .

Answer 22

platelets

Question 23

Neurogenic shock causes

Answer 23

loss of sympathetic tone from Spinal cord injuries above T4-T6
