Chapter 13- Introduction

Question 1

What is defined as inadequate cellular perfusion?

Answer 1

Shock

Shock leads to insufficient delivery of oxygen, water, and glucose to cells.

Question 2

What do cells require to carry out cellular processes?

Answer 2

Oxygen, water, and glucose

These components are essential for energy production in the form of adenosine triphosphate.

Question 3

What happens when cells do not receive adequate perfusion?

Answer 3

They cannot create energy and are categorized as hypoperfused

This condition affects tissues and organs as well.

Question 4

What is the body’s initial response to the early stages of shock?

Answer 4

Attempt to maintain homeostasis

Homeostasis is the balance of all systems of the body.

Question 5

What occurs as shock progresses in the body from tissues to organs to organ systems?

Answer 5

Blood circulation slows and eventually ceases

This leads to inadequate oxygen and nutrient delivery.

Question 6

What are the potential consequences of untreated shock?

Answer 6

Organ and organ system failure, and can be fatal

Prompt treatment is crucial to prevent these outcomes.

Question 7

Name three medical or traumatic events that can cause shock.

Answer 7

• Heart attack
• Severe allergic reaction
• Bleeding

These events require immediate emergency response.

Question 8

What is critical for an EMT when responding to emergencies related to shock?

Answer 8

Be constantly alert to the signs and symptoms of shock

EMTs must provide necessary treatment and transportation for affected patients.

Question 9

True or False: Shock can only occur due to traumatic events.

Answer 9

False

Shock can also occur due to medical events like heart attacks.

Question 10

Cells produce energy in the form of:

Answer 10

Adenosine Triphosphate

Question 11

What is homeostasis ?

Answer 11

A balance of all body systems
