About This Chapter
Asepsis & Infection Control - Chapter Summary and Learning Objectives
In caring for patients, nurses must not only support the treatment of original ailments and conditions, but also work to prevent any further illness including infection. This chapter covers methods to prevent additional sickness in patients while undergoing treatment. The lessons will deal with specific medicine, procedures and agencies that assist in these protections. Take an end-of-lesson quiz to measure how well you have learned the material and feel free to contact an instructor with any questions. These lessons address such topics as:

1. Immune System & Immune Response
Your immune system protects you from foreign invaders that might harm you. When your immune system responds to these threats, it's called an immune response. Learn about two arms of immunity known as antibody-mediated and cell-mediated immunity.
2. Basic Principles of Infection Control
We are going to gain an understanding of microorganisms and what it means to be pathogenic. This lesson will go on to discuss the importance of infection control.
3. Blood Coagulation and Wound Healing
When your blood vessels suffer damage, your body follows a sequence of events to promote blood clotting. In this lesson, you will learn about coagulation cascade and important clotting factors involved in wound healing.
4. The Three Phases of Wound Healing
In this lesson, you're going to learn the fundamental facts about the three phases of wound healing. These phases include inflammation, proliferation, and maturation. When you are through, take the quiz to see what you have learned.
5. Acute Inflammation: Causes, Examples & Impact
This lesson teaches you about what occurs during acute inflammation. We'll discuss the causes and impacts of inflammation and learn terms like arachidonic acid, prostaglandins, leukotrienes, and eicosanoids.
6. Chronic Inflammation: Long Term Consequences
This lesson explores the harmful effects of long-term inflammation. We'll define chronic inflammation, inflammatory mediators, and reactive oxygen species before covering some specific causes of chronic inflammation and its consequences.
7. The Inflammatory Response's Effect on the Entire Body
This lesson will discuss two important roles systemic inflammation is involved in: fever and leukocytosis. It will also discuss the flip-side, two bad components of systemic inflammation: cachexia and anaphylactic shock.
8. Progress of Disease: Infection to Recovery
This lesson will teach you about the five basic steps of the development of disease, what they are called, and what occurs during each phase. We'll talk about the incubation and prodromal period as well as the periods of convalescence, decline, and illness.
9. The Differences Between Infection and Disease
This lesson will go over the differences between an infection and a disease. We'll cover everything from prions and infectivity to opportunistic infections and idiopathic disease. We'll also learn what the etiology of disease is and much more.
10. Chain of Infection: Definition & Example
Infectious disease results from the interaction of an agent, a host, and an environment. Most of these diseases follow a typical chain of infection that ends with an infected host. Understanding the chain of infection can help with both the prevention and treatment of infectious diseases.
11. Role of the CDC & OSHA in Standard Precautions
We are going to look at the two governing agencies for standard precautions: the CDC and OSHA. This lesson will go into their respective roles in regards to standard precautions.
12. Medical Asepsis: Precautions & Case Example
Medical asepsis is a complex and very important topic. This lesson introduces you to its definition, core aspects, and tests your knowledge with a case example.
13. Surgical Asepsis: Definition, Technique & Examples
An operation is about to begin. Necessary components include: surgeon, nurses, patient, instruments, and... surgical asepsis! In this lesson, learn about the importance of maintaining surgical asepsis during a medical procedure.
14. Surgical Asepsis: Sterilization & the Surgical Conscience
This lesson will define surgical asepsis, outline the different types of sterilization procedures, and go over the important concept of maintaining a surgical (sterile) conscience.
15. Antiseptics, Disinfectants & Sterilization
This lesson will discuss the differences between antisepsis, disinfection, and sterilization as well as some of the methods used for sterilization and antiseptic compounds you may have used yourself.
16. What Are Normal Flora & Transient Flora? - Definitions
In this lesson, you're going to learn about the major difference between normal and transient flora, as well as a couple examples of each and how all this applies day to day.
17. Hand Hygiene for Health Care: When & How to Clean Hands
In this lesson, you're going to learn the definition of hygiene, why hand hygiene is important, and step-by-step instructions on how to properly wash your hands.
18. How to Use Alcohol-Based Hand Sanitizers
In this lesson, you'll learn what is better: washing your hands or using a hand sanitizer. You'll learn what hand sanitizer you need to get and how to properly use one.
19. How to Apply & Remove Non-Sterile Gloves
In this lesson, you're going to learn how to put on and remove non-sterile gloves. By following the steps in this lesson, you'll help keep yourself and your patients safe.
20. Autoclaves and Moist Heat Sterilization: Use With Surgical Tools
This lesson will discuss what an autoclave is, how it works, and what it's used for. We'll also discuss the disadvantages of an autoclave, bacterial endospores, and how sterilization is important in the context of nosocomial infections.
21. Using Alcohol as a Disinfectant and Antiseptic
This lesson will discuss how alcohol can be used as a disinfectant and antiseptic but not a sterilant. We'll also talk about what it kills and doesn't kill and why ethyl alcohol and isopropyl alcohol are the two most commonly used alcohol-based disinfectants.
22. Infection Transmission & Susceptibility
Avoiding infection in medical settings is critical, especially in people who are already sick or injured. In this lesson we'll learn about how a person becomes infected and risk factors that make them susceptible to infection.
