Study Notes

Signs and Symptoms of Infectious Disease

Signs of infectious diseases can be observed by a healthcare professional, for example, swollen lymph nodes or tachycardia
Symptoms of infectious diseases are reported by the patient, for example, chills or fatigue

Universal Precautions

Universal precautions are a set of safety measures designed to protect healthcare workers from exposure to infectious agents
They apply to all patients, regardless of their known or suspected infectious status
Universal precautions involve treating all blood and body fluids as potentially infectious, including blood products, human tissue, and certain body fluids
Healthcare workers should wear gloves when handling blood or body fluids, and after any potential contact with blood, for example, during venipuncture or cleaning up blood spills
Healthcare professionals should be aware of potential infectious agents such as HIV and Hepatitis B

OSHA and Needle Safety

Healthcare professionals must implement needle safety devices
Facilities must maintain a detailed log of all needlestick or sharps injuries

Transmission-Based Precautions

There are three categories of transmission-based precautions: Contact, Droplet, and Airborne
Contact precautions are used for infections that are spread through direct or indirect contact, such as by touching a contaminated surface
Droplet precautions are used for infections that are spread through respiratory droplets, expelled when an infected person coughs or sneezes
Airborne precautions are used for infections that are spread through small particles that can remain suspended in the air for long periods

Medical Asepsis

Medical asepsis is a set of practices aimed at reducing the number of microorganisms and preventing their growth
Medical asepsis includes practices like handwashing, glove use, and gowning

Surgical Asepsis

Surgical asepsis is the complete removal of all microorganisms
Surgical asepsis is required for invasive procedures such as inserting urinary catheters, endoscopies, and wound care

Disinfection

Disinfection is the process of destroying or inactivating pathogens on surfaces and items
The process involves submerging instruments in a chemical solution, ensuring contact with every surface
Glutaraldehyde is a disinfectant used in clinical settings, but it requires long submersion times and is costly
Bleach solutions are an effective and inexpensive alternative to glutaraldehyde
Disinfection is used on medical supplies, equipment, and clinical surroundings, but not on patients.
