    Study Notes

    Safety Protocols and Emergency Procedures

    • In the event of a bleach splash to the eyes, flush with water for at least 15 minutes.
    • Accidental needlestick injuries require cleaning the site with soap and water for 30 seconds.
    • For electrical shock incidents, the first action is to shut off the electricity source.

    Infectious Diseases and Pathogens

    • HIV is the virus responsible for AIDS.
    • Communicable infections can be spread from person to person.
    • HBV primarily targets the liver, while nosocomial infections occur within healthcare settings.

    Infection Control and Prevention

    • Follow standard precautions with all patients at all times.
    • The chain of infection includes an exit pathway, reservoir, and susceptible host.
    • Proper hand hygiene is crucial for preventing healthcare-associated infections.

    Laboratory and Workplace Safety

    • OSHA mandates safe working conditions; follow posted precautions in isolation rooms.
    • Many unsafe practices include eating or stashing food in the lab and wearing open-toed shoes.
    • The blue section of the NFPA symbol indicates a health hazard; proper labeling and cleaning are essential.

    Personal Protective Equipment (PPE)

    • N95 respirators are required in airborne isolation situations.
    • Gloves should be worn during phlebotomy to protect against exposure to patient blood.
    • The correct order for putting on protective clothing is gown first, then mask, with gloves last.

    Fire Safety and Emergency Preparedness

    • The fire triangle consists of fuel, oxygen, and heat; chemical reactions are the fourth component in the tetrahedron.
    • Class B fires involve flammable liquids; use appropriate extinguishing methods.
    • RACE stands for Rescue, Alarm, Confine, Extinguish in fire emergencies.

    Vectors and Transmission Modes

    • Droplet transmission occurs through sneezing or coughing, while vehicle transmission involves contaminated food or water.
    • Vector transmission can involve organisms like fleas or ticks, whereas direct contact involves surface contamination.

    Health and Stress Management

    • Exercise reduces stress by releasing endorphins.
    • Major life changes are generally unhealthy stress management methods.
    • Vaccination is crucial for immunity; recovered individuals develop antibodies against specific viruses.

    Compliance and Identification

    • The CDC monitors disease control; OSHA governs workplace safety regulations.
    • Knowing the definition of a pathogen is essential—pathogenic microbes can cause disease.
    • Laboratory protocols require goggles when exposure to sprays or splashes is possible.

    Miscellaneous

    • Proper practices for cleaning spills include using disinfectants and ensuring the biohazard symbol is properly utilized.
    • Withdrawal precautions apply to highly transmissible diseases, emphasizing protective measures.
    • Fluids like isopropyl alcohol require safety data sheets to handle safely in labs.### Infection and Health Terminology
    • A positive PPD test indicates exposure to tuberculosis.
    • Acute conjunctivitis is an inflammation of the conjunctiva, often resulting in redness and irritation.
    • German measles, or rubella, is a contagious viral infection characterized by a rash and fever.
    • Mononucleosis, commonly caused by Epstein-Barr virus, is known for fatigue, fever, sore throat, and swollen lymph nodes.

    Healthcare-Associated Infections

    • Healthcare-associated infections include infections contracted during medical care, such as an infected catheter site in an ICU patient.

    Specimen Handling

    • If a patient specimen tube is stained with blood, it should be wiped with disinfectant to prevent contamination.

    Fire Safety

    • Flammable liquid fires should be extinguished using a class B fire extinguisher, specifically designed for such materials.

    Body Fluids and Standard Precautions

    • Sweat is exempt from standard precautions, while joint fluid, saliva, and urine are not.

    Hand Hygiene

    • Alcohol-based hand sanitizers can replace hand washing if hands are free from visible dirt or organic matter.

    Fire Classes

    • Class D fires involve combustible metals and require specific fire extinguishing methods.

    Symptoms of Shock

    • A slow, strong pulse rate is not a symptom of shock; typical symptoms include an expressionless face, increased shallow breaths, and pale, cold, clammy skin.

    Hepatitis B

    • The presence of HBsAg in a patient's serum confirms active hepatitis B infection.

    Biohazards

    • Biohazards are substances that pose a risk to health.

    Hazardous Material Regulations

    • OSHA (Occupational Safety and Health Administration) enforces regulations for labeling hazardous materials and ensuring safety in the workplace.

    Fire Extinguisher Use

    • The acronym PASS (Pull, Aim, Squeeze, Sweep) is used to remember the steps for using a fire extinguisher.

    Hazard Communication

    • The HazCom Standard is commonly known as the Right to Know Law, focusing on the communication of hazards associated with chemicals.

    Emergency Response

    • If a coworker's clothing catches fire, the best response is to smother the flames with a fire blanket.

    Personal Protective Equipment (PPE)

    • The OSHA Bloodborne Pathogens (BBP) Standard mandates the availability of PPE for employees in medical labs.

    Chemical Safety

    • Adding bleach to a cleaner is unsafe and violates chemistry safety rules.

    Infection Susceptibility

    • The use of antibiotics can increase susceptibility to infections by disrupting normal flora.

    Transmission of Infection

    • Indirect contact occurs when infection transmission happens through contaminated surfaces like bed linens.

    Neutropenic Isolation

    • Neutropenic isolation is designed for patients with a low white blood cell count to protect them from infections.

    Removing Protective Clothing

    • Correct order for removing protective gear is gloves, gown, and then mask to minimize contamination risk.
