OEC 6th Edition Chapter 10

Shock can best be described as

Inadequate tissue perfusion in which cells do not receive sufficient amounts of oxygen and nutrients.

A patient in early onset of shock informs you that he has had severe diarrhea and vomiting over the past four days. Given this history, you would recognize the pathophysiology of the shock is probably related to:

A) the loss of red blood cells.

B) decreased formed elements in the blood.

C) stoppage of the capillaries.

D) the loss of plasma volume.

D) the loss of plasma volume.

The four major types of shock are

hypovolemic, cardiogenic, obstructive, and distributive.

Which of the following statements made by a patient's family member would lead you to suspect that the patient is suffering from hypovolemic shock?

A) "He has had a rash for the past three days."

B) "He cannot stop throwing up."

C) "He has been taking an antibiotic for a chest cold."

D) "He got up this morning and was having a hard time breathing."

B) "He cannot stop throwing up."

A patient in shock with abdominal pain indicates he noticed lots of blood in the toilet after having a bowel movement this morning. You would recognize the possibility of what type of shock?

A) Septic

B) Hypovolemic

C) Hypoxic

D) Obstructive

B) Hypovolemic

A patient who sustained blunt trauma to the abdominal and pelvic areas in a very serious collision is probably in which type of shock?

A) Obstructive

B) Cardiogenic

C) Distributive

D) Hypovolemic

D) Hypovolemic

Septic shock is caused by:

an infection.

What condition could cause cardiogenic schok?

Pulmonary embolism

When performing a primary assessment, one of the first signs that the body may be in shock is:

Tachycardia, condition where heart beats abnormally fast

Where is shock best treated?

The hospital, rapidly address ABCD issues then transport quickly

Phases of shock

Compensated and decompensated then irreversible

Atherosclerosis

When cholesterol and lipid plaques form in arteries 

Congestive heart failure

When the heart cannot adequately pump blood to body tissues

Pulmonary edema

Accumulation of fluid in the lungs

Angina pectoris

Chest pain or discomfort caused by ischemia (lack of oxygen) of the myocardium (heart muscle)

Pericarditis

Inflammation of the pericardial sac that surrounds the heart

Assessing cardiovascular emergencies

Patients in cardiac arrest will be unresponsive, begin CPR, call for AED with ALS assistance. If ABCDs are stable, conduct secondary assessment. Be aware of medications like nitroglycerin or aspirin
