Quiz 6 Med-Surg, Shock-Chapter 19 questions from text book and study guide plus important facts from powerpoint

Fluid replacement continues until:

a mean arterial pressure of 60 mm Hg or greater is attained and evidence of adequate tissue perfusion

Ischemia

an inadequate blood supply to an organ or part of the body, especially the heart muscles.

Shock uses what kind of metabolism?

anaerobic metabolism

A person has a severe allergic reaction that results in bronchoconstriction and increased capillary permeability. This type of shock is:

anaphylactic

Which type of shock occurs suddenly following exposure to a substance for which the patient had already developed antibodies?

anaphylactic

The body of a patient with neurogenic shock is unable to compensate with vasoconstriction because:

the vasomotor center is incapacitated

Is change in the level of consciousness the best indicator for cerebral perfusion?

yes

Which are compensatory mechanisms in shock related to the sympathetic nervous system response? select all that apply

1) decreased blood flow to the kidneys 2) Renin-angiotensin-aldosterone system activated

causes of obstructive shock are: select all that apply

1) tension pneumothorax 2) pericardial tamponade 3) pulmonary embolus 4) superior vena cava syndrome 5) abnormal compartment syndrome

Which are three types of distributive shock? Select all that apply

1)Anaphylactic 2) Septic 3) Neurogenic

Which descriptions relate to distributive shock? Select all that apply.

1)Fluid pools in dependent areas of the body2)Problem is with excessive dilation of blood vessels

4 types of shock-

1. Hypovolemic 2. Cardiogenic 3. Distributive 4. Obstructive

Subtypes of vasogenic shock

1.Anaphylactic shock 2. Septic shock 3. Neurogenic shock

Which descriptions are related to hypovolemic shock? Select all that applay.

1.Caused by rapid blood loss, dehydration, hemorrhage, severe diarrhea or vomiting, and excessive perspiration 2. Occurs when the circulating blood volume is inadequate to maintain supply of oxygen and nutrients to tissue

patient with vasopressors should have their vital signs monitored every :

15 minutes

hypertrophic cardiomyopathy

A condition in which the heart muscle becomes abnormally thick.

mechanical obstruction to blood flow and a resultant reduction in cardiac output occur

Obstructive shock

Occurs when the heart fails to pump

Cardiogenic shock

myocardial contractility

Cardiogenic shock

widespread vasodilation

Distributive

blood volume loss

Hypovolemic

Circulating blood volume is inadequate to maintain supply of oxygen and nutrients to body tissues

Hypovolemic shock

Peritonitis, diarrhea, vomiting, hemorrhage lead to :

Hypovolemic shock

Once sufficient fluids have been administered a ____________ agent may be ordered to increase myocardial contractility

Inotropic agent

Deprived of adequate oxygen, cells resort to anaerobic metabolism, which produces lactic acid and results in:

Metabolic acidosis

Spinal cord injury may lead to:

Neurogenic shock

disruption in the nervous system affects the vasomotor center in the medulla

Neurogenic shock

Tension pneumothorax,pericardial tamponade, superior vena cava may lead to:

Obstructive shock

impaired circulatory blood flow

Obstructive shock

What is disrupted in neurogenic shock ?

Sympathetic

What makes anaphylactic, septic, and neurogenic shock falls under the sames category of shock?

Vasodilation

Excessive dilation of the blood vessels or decreased vascular resistance

Vasogenic

Common cause of Cardiogenic shock:

When heart fails to pump

Edema in anaphylactic shock is caused by :

fluid leaking out of the capillaries into the tissues

A woman experiences burns over 80% of her body. The nurse suspects she has:

hypovolemic shock

Following an automobile accident, a 35-year old man experienced severe hemorrhage. This type of shock is classified as:

hypovolemic shock

myocarditis

inflammation of the heart muscle

Why should a cardiogenic patient not receive large volumes of fluid through IV?

large volumes of fluid may further compromise a failing heart

Crystalloids provide what?

replacement water and electrolytes for all fluid compartments

inadequate tissue perfusion resulting in impaired cellular metabolism :

shock

The adrenal cortex secretes aldosterone to promote :

sodium retention
