Infection Control Quiz & Flashcards

Hand hygiene is a fundamental practice to prevent infection transmission.

PPE is designed to protect individuals from exposure to infectious agents.

Herd immunity reduces transmission by immunizing a large portion of the population.

An autoclave sterilizes equipment by using steam under pressure.

Vaccines stimulate the immune system to produce antibodies against pathogens.

Antibiotic resistance makes infections harder to treat, leading to longer illness durations.

The chain includes reservoirs, portals of entry, and other steps in infection transmission.

Fomites are inanimate objects that can carry and spread infectious agents.

Vaccination prevents the spread of diseases by immunizing individuals.

Isolation separates infected individuals to prevent the spread of infection.

Surveillance monitors the spread of infections to enable timely interventions.

Standard precautions are used to prevent the transmission of infectious diseases.

An outbreak is a sudden increase in the number of cases of a disease.

Aseptic technique prevents contamination and infection during medical procedures.

Quarantine restricts the movement of those exposed to a contagious disease to prevent its spread.

Sterilization kills all microorganisms, while disinfection reduces them to safe levels.

Airborne precautions protect against pathogens that can travel long distances.

Infection control nurses focus on monitoring and implementing infection prevention strategies.

Contact precautions prevent the spread of infectious agents through direct or indirect contact.

Antiseptics inhibit the growth of microorganisms on living tissue.

Cohorting involves grouping patients with the same infection to prevent cross-infection.

Surgical masks protect against large droplets and prevent the spread of infectious agents.

Colonization refers to bacteria present without causing disease.

The incubation period helps determine how long individuals may need to be quarantined.

Proper wound care prevents infections and promotes faster healing.

Negative pressure rooms prevent airborne contaminants from escaping, thereby protecting others.

Chlorine bleach disinfects by denaturing proteins and disrupting cell membranes.

A healthcare-associated infection is acquired while receiving treatment in a healthcare facility.

An endemic infection is constantly present in a population or geographic area.

Training ensures staff are knowledgeable about protocols to prevent infection spread.

Cross-contamination refers to the transfer of harmful microorganisms from one person or object to another.

A sterile field maintains a controlled environment free of microorganisms during procedures.

Universal precautions are guidelines to prevent the transmission of bloodborne pathogens.

Sterile means completely free of all microorganisms, whereas clean refers to removing dirt and debris.

UV light destroys the DNA of microorganisms, rendering them inactive.

A carrier harbors an infectious agent without showing symptoms, potentially spreading it to others.

Droplet transmission occurs when infectious agents are spread through large respiratory droplets.

Epidemiologists study disease patterns and causes to control their spread.

Proper disposal prevents the spread of infections and protects public health.

A pathogen is a microorganism that can cause disease.

Vaccines help establish herd immunity by immunizing a large portion of the population.

Individual immune response varies and some pathogens can mutate, affecting vaccine effectiveness.

Surveillance helps detect and monitor outbreaks to implement control measures.

Autoclaving is a common method that uses steam under pressure to sterilize equipment.

The primary goal of hand hygiene is to reduce the transmission of infectious agents.

Personal Protective Equipment (PPE) protects healthcare workers from exposure to infectious agents.
