31
Q

Pump issue in a shock

A

Cardiogenic

32
Q

Volume issue ins hock

A

Hypovolemic

33
Q

Pipe issue in shock

A

Distributive
Obstructive

34
Q

Absolute hypovolemia shock

A

Hemorrhage, bleeding from trauma, surgery, GI bleed, ruptured aortic aneurysm

& non hemorrhagic
Vomiting , diarrhea, excessive diuresis , DI

35
Q

Relative hypovolemic shock

A

Fluid shift that stays internal
Extravascular or intracavity
Such as acites , burn injury, peritonitis , bowel obstruction

36
Q

Cues for hypovolemic a shock

A

Confused, vascular resistance increased, hypotensive, oliguria ,normothermic

37
Q

How much fluid resuscitate for hypovolemia

A

Every 1 unit of blood loss 3 units of fluid for

38
Q

How do we position a hypovolemic pt

A

Lay them flat ..elevate the legs

39
Q

S/s of cardiogenic shock

A

JVD, pulmonary edema( fluid clear ,bubbly,frothy ) , muffled heart sounds

40
Q

What can an injury when the chest pressed against the steering wheel cause?

A

Cardiogenic shock
Bruising or stamp mark

41
Q

Treatment for cardiogenic shock

A

O2
Position of comfort
Diuretics
Lower bp
Nasopresser , metropolol
Watch I&O
Minimize fluids
Balloon pump & VAD

42
Q

Distributive shock (pipes)

A

Anaphylactic
Neurogenic
Septic

43
Q

What should we be careful when it comes to latex allergies

A

Be cautious what you insert like Foley catheters , gloves etc

44
Q

Signs of MODS ( multiple organ dys system )
Multiple organ failure

A

BUN and creatine high with low urine output = kidney

Higher we go up on Fio2 and paO2 goes down shows that the lungs are failing

45
Q

At what stage is MODS considered?

A

Refractory

46
Q

What can we use when a pt has bradycardia for neurogenic shock

A

Atropine(short term)

47
Q

Obstructive shock causes

A

Pulmonary embolism
Pericardial tamponade
Hemopneumothorax
Tension pneumothorax

48
Q

What is tension pneumothorax caused by

A

High peep

49
Q

Physical assessment or obstructive shock

A

Signs of organ perfusion

50
Q

What does someone with pulmonary embolism present

A

Chest pain , dont hear anything abnormal in lungs or heart

51
Q

What would we hear in pneumothorax

A

Decreased breath sounds on the side it is collapsed

52
Q

What would you hear with hemopneumothorax

A

Wont hear anything on side it is ad or it will be decreased

That’s why it is important to listen to all areas of the lungs

53
Q

How to calculate pulse pressure

A

Systolic pressure - diastolic blood pressure

54
Q

Normal pulse pressure

A

Normal 40-60 mmHg

55
Q

Narrow pulse pressure

A

<40 mmHg

Early indication of shock than drop in systolic BP

56
Q

Widened pulse pressure

A

> 80mmhg
Septic pt

57
Q

Sustained intracranial pressure

A

above 20 mmHg
Widened pulse

58
Q

Labs for obstructive shock

A

ABGs respiratory alkalosis to respiratory acidosis
Lactic acid- severe o2 deprivation
CBC - H&H, infection

59
Q

When do we expand volume

A

Septic , hypovolemic, anaphylactic

60
Q

How can we expand the volume

A

Crystaloids (NS , lactated ringers)
Colloid ( albumin, RBC , )

61
Q

Albumin

A

Volume expander
Large protein that pulls volume from out to interstitial vascular space

62
Q

What is important to note about products such as RBC , plasma, albumin when administering

A

Assess for anaphylactic reactions and over load

63
Q

Why do you want to give diuretic with products such as albumin or RBC

A

To help regulate , we dont want to drown them
