HS Flashcards on Pathogens and Microorganisms

Questions and Answers

How do nonpathogens differ from pathogens?

Nonpathogens are not harmful and pathogens are harmful.

What does federal law require of employers in regard to the hepatitis B vaccine?

Study Notes

Nonpathogens vs Pathogens

Nonpathogens are harmless organisms, whereas pathogens are responsible for causing diseases.

Hepatitis B Vaccine Requirements

Federal law mandates that employers provide the hepatitis B vaccine at no charge to healthcare workers exposed to blood or body fluids carrying the HBV virus.

Growth Conditions for Microorganisms

Microorganisms require a warm environment, body temperature, and darkness to grow and reproduce effectively.

Infection Mechanisms of Pathogenic Organisms

Pathogenic organisms can cause infection by producing toxins and by invading and destroying living cells.

Endogenous vs Exogenous Diseases

Endogenous diseases originate from organisms within the body; exogenous diseases come from external sources.

Common Nosocomial Infections

Common nosocomial infections include those caused by Staphylococcus, Pseudomonas, and Enterococci.

Infection Control in Health Care Facilities

Health care facilities implement infection-control programs to prevent and manage nosocomial infections.

Transmission Prevention

Handwashing serves as a critical method for preventing the portal of exit and mode of transmission of infectious agents.

Skin's Role in Infection Prevention

Intact, unbroken skin acts as a barrier to prevent pathogens from entering the bloodstream.

Importance of Health in Infection Prevention

A healthy, well-rested individual is less susceptible to infections and promotes overall health.

Cleaning Protocols

Cleaning and sterilization of blood-covered instruments are vital for controlling the mode of transmission and source of reservoirs.

Identification of Causative Agents

Rapid and accurate identification of organisms is crucial in determining the causative agent of infections.

Aseptic Techniques

Common aseptic techniques include handwashing, maintaining good personal hygiene, thorough cleaning, and wearing gloves.

Antisepsis

Antiseptic methods prevent or inhibit the growth of pathogenic organisms but are ineffective against spores and some viruses.

Disinfection

Disinfection processes destroy or eliminate pathogenic organisms to ensure safety and hygiene.

Sterilization

Sterilization completely eradicates all microorganisms, both pathogenic and nonpathogenic, ensuring surfaces and instruments are free from all microbial life.
