Study Notes
Health-Care Associated Infections (HAIs)
- Circumstances like invasive procedures, prolonged hospitalization, and increased use of antibiotics elevate HAI risk.
- Encounters such as surgery, catheter insertion, and ventilator use increase patient susceptibility to HAIs.
- Infections considered HAIs often include catheter-associated urinary tract infections, surgical site infections, and pneumonia.
Post-Exposure Actions for Nurses
- After exposure to bodily fluids, a nurse should perform immediate washing of the affected area.
- Reporting the incident to a supervisor and completing an incident report is essential.
- Follow-up testing for potential infections may be necessary, depending on exposure circumstances.
Pathogens and Resistance
- Viruses with protective envelopes cannot be treated with antibiotics, as seen in pathogens like the West Nile virus.
- Patients with compromised immune systems or chronic conditions can be considered susceptible hosts in the infection chain.
Microorganisms of Concern
- Blood-borne pathogens include HIV, Hepatitis B, and Hepatitis C, which can be transmitted through needle sticks.
- Informing patients about the proper use of prescribed antibiotics is crucial for preventing antimicrobial resistance.
Factors Leading to Antimicrobial Resistance
- Antibiotic use in animals can foster drug-resistant bacteria that may infect humans through the food chain or environment.
- Agents like MRSA, VRE, and certain strains of E. coli have developed resistance in healthcare environments.
Chain of Infection Components
- The component that involves an infectious agent leaving its reservoir is known as the portal of exit.
- Transmission modes for respiratory infections like influenza typically include droplet and airborne spread.
Microbial Resistance Dynamics
- A microorganism is categorized as resistant if it cannot be inhibited by two or more antibiotics.
- Contributing factors to microbial resistance include overuse and misuse of antibiotics, poor infection control practices, and lack of new antibiotic development.
