Study Notes

Infection Prevention Overview

  • Infection prevention involves a collection of methods to inhibit disease transmission.
  • Key links in the infection chain include susceptible hosts and modes of transmission.

Essential Practices for Nursing Assistants (NA)

  • Wearing gloves breaks the mode of transmission, thus reducing disease spread.
  • Vaccination against hepatitis B helps protect NAs by targeting the susceptible host link.
  • NAs come into contact with microorganisms continually through touching various surfaces.
  • Proper hand hygiene, including washing hands for at least 20 seconds, is the most critical action for disease prevention.

Vulnerabilities and Precautions

  • The elderly are especially susceptible to infections due to limited mobility.
  • NAs should employ Standard Precautions universally for all residents.
  • Body fluids, including urine, are part of Standard Precautions and must be handled carefully.

Hand Hygiene Techniques

  • Hand hygiene encompasses using either plain or antiseptic soap and water or alcohol-based hand rubs.

Personal Protective Equipment (PPE) Usage

  • The correct order for donning PPE is to first wear a gown, followed by a mask and goggles, ending with gloves.
  • After providing care, gloves should be safely discarded, especially if they are torn.

Disinfection Facts

  • Disinfection reduces pathogens but does not eliminate all, unlike sterilization.
  • Cleaning spills should always begin with the NA wearing gloves.

Transmission-Based Precautions

  • These precautions are supplementary to Standard Precautions; they do not replace them.
  • Direct contact with blood or body fluids is a primary transmission route for blood-borne pathogens.

Hepatitis B (HBV) and Bloodborne Pathogen Standards

  • The HBV vaccine is crucial for healthcare workers to prevent the disease.
  • The Bloodborne Pathogen Standard mandates employers to maintain an exposure control plan.

Tuberculosis (TB) Information

  • TB is an airborne disease and can be contracted through coughing.
  • Individuals with active TB can transmit the disease to others.

MRSA and C. difficile Management

  • MRSA spreads primarily through direct physical contact; effective hand washing is essential to control its spread.
  • C. difficile prevention requires thorough hand washing and careful management of contaminated waste.

Responsibilities of Nursing Assistants

  • NAs should adhere to Standard Precautions for all residents, ensuring a consistent approach to infection prevention.
