Q

Shock: How does the body respond to shock?

A

By activation of the inflammatory response. Will then have hyperperfusion of tissues, hypermetabolism due to increased need for energy since tissues aren’t being perfused.

Q

Shock - Patho, Cellular Changes: What happens when inflammatory response kicks in?

A

You have increased permeability which leads to leaky vessels. Electrolytes and fluids go in-and-out.

Mitochondria will be damaged and you will have cell death

Q

Shock - Patho, Cellular Changes: What usually occurs in aerobic metabolism?

A

That is how we normally function. Glucose/oxygen goes into cell and outputs CO2 and Water to produce a lot of energy

Q

Shock - Patho, Cellular Changes: How does anaerobic work?

A

This is only using glucose. Only glucose goes into cell and lactic acid gets kicked out. This releases only a small amount of energy and creates an oxygen debt to break down all that lactic acid.

Q

Shock - Patho, Cellular Changes: What is the important thing to realize for shock on cellular level?

A

When patient goes into shock, they have inadequate tissue perfusion so no oxygen.

Not enough oxygen to do aerobic metabolism so they’lll switch to anaerobic. Causes buildup of lactic acid.

Q

Shock - Patho, BP Regulation: How does RAAS play a role here?

A

If kidneys not getting perfused, RAAS will be kicked in. Will have Angiotensin I -> Anngiotensin II whick causes vasoconstriction

Also have ADH kicked in that causes kidneys to retain water to help increased blood volume and blood pressure in patients.

78
Q

Shock Mx - Vasoactive Med Therapy: Why can some drugs be listed as both inotropes and vasopressors?

A

At lower dose, dopamine is inotrpope. At higher, is a vasopressor.

Medications can have multiple uses

79
Q

Shock - Nutritional Support: Why is this important?

A

Patient have an increased metabolic rate and an increased caloric need. They need more energy.

80
Q

Shock - Nutritional Support: How many calories do they usually need?

A

Around 3000 calories

81
Q

Shock - Nutritional Support: What gets released early in shock in the body?

A

Catacholamines, which are usually released when you are physically are emotionally stressed

82
Q

Shock - Nutritional Support: How do catacholamines affect the body?

A

It depletes the glycogen storage. That is why these patients need nutrition

83
Q

Shock - Nutritional Support: What type of nutrition is preferred?

A

Enteral Nutrition. Will get feed through a tube feed and not through TPN through IV.

84
Q

Shock - Nutritional Support: Enteral nutrition helps cut down what?

A

Stress ulcers, which may occur frequently because blood has shunted organs to vital organs, meaning GI tract is not getting enough blood. Helps reduce stress ulcers.

85
Q

Shock - Nutritional Support: Patients should be put on some sort of anti-acid, H2 blockers, or PPI why?

A

Because they will help inhibit gastric acid secretion and therefore decrease possibility of stress ulcer

86
Q

Hypovolemic Shock: How common is this?

A

Most common type of shock

87
Q

Hypovolemic Shock: What is this?

A

You have decreased intravascular volume. Occurs when theres a reduction in intravascular volume by 15-30%. Patient has lost 750 - 1500 mL of circulatory blood/fluid.

88
Q

Hypovolemic Shock: What can cause this?

A

Dehydration, severe edema, ascites (shifting of fluids), or blood loss (hemorrhage through surgery or accident trauma).

Decrease in intravascular volume

89
Q

Hypovolemic Shock - Sequence of Events: What happens to the body once there is a decrease in intravascular volume?

A

Decreased venous return (decreased ventricular filling) –> Decreased stroke volume –> decreased cardiac output –> decreased tissues perfusion

90
Q

Hypovolemic Shock - Sequence of Events: What happens to the body once there is decreased tissue perfusion?

A

You see an increase in lactic acid because thats where we flip from aerobic to anaerobic metabolism

91
Q

Hypovolemic Shock Tx: What is the first step you should do ?

A

Identify and treat the cause. If there are bleeding, stop the bleeding and give them blood.

If losing fluid because nauseated or diarrhea, stop them.

92
Q

Hypovolemic Shock Tx: What is the first thing given after your treat the underlying cause?

A

You want to give them fluid and blood replacement.

93
Q

Hypovolemic Shock Tx: To replace fluid, we need to make sure that patient has what?

A

Two large gauge IVs that are 18 gauge or larger.

94
Q

Hypovolemic Shock Tx: Fluid will be replaced according to what rule?

A

3-to-1 rule. Three mLs of crystalloids for every mL of blood loss.

95
Q

Hypovolemic Shock Tx: What is another thing you can do instead of fluid and blood replacement?

A

You can do redistrubtion of fluid or pharmacologic therapy

96
Q

Hypovolemic Shock Tx: How does redistribution of fluid work?

A

Involves modified trendelenburg position. Legs elevated which promotes return of blood to heart. Promotes the venous return

97
Q

Hypovolemic Shock Tx: What meds can be given to reverse cause if they’re having diarrhea?

A

Give them an anti-diarrheal

98
Q

Hypovolemic Shock Tx: What meds given if they are nauseated and vomitting?

A

Give them anti-emitics. This includes zofran and phenergan.

99
Q

Hypovolemic Shock Tx: What meds can be given for DKA patient due to diuesis?

A

Treat cause and give them insulin due to hypoglycemia.

100
Q

Hypovolemic Shock Tx: Meds given will focus on what

A

Treating the underlying cause that caused them to go into this

101
Q

Hypovolemic Shock Tx: Patients are usually placed in trendelenburg when what happens to them?

A

When they become hypotensive, in hopes to raise blood pressure.

102
Q

Hypovolemic Shock Tx: How to make sure you administer blodo and fluids safely?

A

By implementing safety measures and making sure you document what youre doing and monitor for complications

103
Q

Hypovolemic Shock Tx: What are some things you would look out for with this population?

A

Vital signs (BP, HR, RR to make sure not fluid overloaded, O2 Sat, CVP, Lung Sounds, Lactate Levels)

Monitor ABGs

Fluid overload complications from abdominal compartment syndrome

104
Q

Hypovolemic Shock Tx: What intervention can be given to help them out initially?

A

Can give them oxygen, because it increased amount of O2 carried by the hemoglobin in the blood.

105
Q

Cardiogenic Shock: When does this occur?

A

When the hearts ability to contract and pump is impaired and the supply of oxygen in inadequate for heart and tissue.

106
Q

Cardiogenic Shock: What changes occur in the body due to this?

A

Heart can’t pump effectively leading to decreased CO. Oxygen blood not getting out leading to decreased MAP

107
Q

Cardiogenic Shock: What are some causes of this?

A

MI that affected left side of heart.

Severe heart failure

Anything that impacts the heart can lead ot this

108
Q

Cardiogenic Shock: What CMs can they develop?

A

Angina, Dysrhythmias, Fatigue, Impending Doom, Hemodynamically Unstable

109
Q

Cardiogenic Shock - Mx: What is one of the first things you want to do?
