Chapter 12 Shock Module review

Which of the following is the last measureable factor to change in shock? -Blood pressure -LOC -Heart rate -Oxygenation

Blood pressure is the last measureable factor to change in shock.

What is generally the best position to place a patient with cardiogenic shock? -Supine -Sitting/semi-sitting -Fowler -Left lateral recumbent

Generally, because fluid is collecting in the lungs, a patient is often able to breathe better in a sitting or semi-sitting position.

Which of the following is a potentially severe complication of neurogenic shock? -Syncope -Hypothermia -Pulmonary embolism -Dehydration

Body temperature in a patient with neurogenic shock can rapidly fall to match that of the environment. In many situations, significant hypothermia occurs, severely complicating the situation.

Distributive shock is the result of which of the following? -Rapid deoxygenation -Low fluid volume -Poor vessel function -Pump failure

Distributive shock results from poor vessel function.

Which of the following is indicated in almost every type of shock? -Control bleeding -Place the patient in a supine position -Request ALS assistance -Administer high-flow oxygen

High-flow oxygen administration is a potential treatment in almost every type of shock.

Which of the following terms is used to describe a balance of all body systems? -Hypothermia -Diffusion -Perfusion -Homeostasis

Homeostasis is the balance of all body systems.

__________ shock is characterized by rapid, weak pulse; low blood pressure; a change in mental status; cyanosis; cool, clammy skin; and an increased respiratory rate. -Hypovolemic -Obstructive -Cardiogenic -Anaphylactic

Hypovolemic shock is characterized by rapid, weak pulse; low blood pressure; a change in mental status; cyanosis; cool, clammy skin; and an increased respiratory rate.

What is perfusion? -The flow of blood through body tissues and vessels -The force or resistance against which the heart pumps -A passive process in which molecules move from an area with a higher concentration of molecules to an area of lower concentration -The presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area

Perfusion is the flow of blood through body tissues and vessels.

Select the correct answers to the question below. Which of the following are types of distributive shock? -Neurogenic shock -Cardiac shock -Septic shock -Hypovolemic shock

Septic and neurogenic shock are examples of distributive shock.

When treating a patient in shock from any cause, what is the first thing you should do? -Control life-threatening hemorrhage with direct pressure or tourniquet application. -Open and maintain airway. -Maintain normal body temperature. -Provide high-flow oxygen.

The first thing you should do is open and maintain the airway.

You arrive on scene to find a conscious 58-year-old woman sitting up and reporting severe chest pain and shortness of breath. She is anxious and tells you she feels like she is going to die. Physical examination shows that her skin is pale, cool, and clammy and her pulse is rapid, weak, and irregular. Her breathing is labored, with a respiratory rate of 28 breaths/min. Her SpO2 is 90%. Lung sounds show crackles in all fields. Blood pressure is 92/60 mm Hg. What is your differential diagnosis of this patient? -Neurogenic shock -Hypovolemic shock -Septic shock -Cardiogenic shock

The patient is displaying signs of cardiogenic shock, including chest pain; anxiety; cool, clammy skin; crackles; and low blood pressure.

You are treating a patient presenting with labored breathing, absent peripheral pulses, and dilated pupils. These are indications of what? -Decompensated shock -Compensated shock -Irreversible shock -Psychogenic shock

These are signs of decompensated shock.
