Study Notes
Pathogen Classification
- Bacteria are classified based on shape, such as spherical (cocci), rod-shaped (bacilli), and spiral-shaped (spirochetes)
Viruses
- Influenza is caused by a virus, specifically the influenza virus
Fungi
- Fungi can cause infections like thrush and histoplasmosis
Vectors
- Mosquitoes are an example of a vector for spreading disease
Hospital-Acquired Infections
- Hospital-acquired infections are now commonly referred to as healthcare-associated infections (HAI)
- Hospital-acquired infections can be caused by pathogens like MRSA and C. difficile
Blood-Borne Pathogens
- Blood-borne pathogens like HIV and Hepatitis B are usually transmitted in a hospital setting through needlestick injuries or contact with infected bodily fluids
Standard Precautions
- Standard Precautions are guidelines used in healthcare settings to prevent the transmission of infectious diseases
- The purpose of Standard Precautions is to reduce the risk of occupational exposure to blood-borne pathogens
Body Fluids
- The following bodily fluids are considered potentially infectious: blood, semen, vaginal secretions, cerebrospinal fluid, synovial fluid, pleural fluid, peritoneal fluid, and amniotic fluid
- Sweat is not considered a potentially infectious bodily fluid
Hand Hygiene
- Hands should be washed with soap and water when they are visibly soiled or contaminated with bodily fluids
Specimen Transport
- Specimens should be transported in a sealed container or bag with a biohazard label
Exposure Incidents
- Personnel should report exposure incidents regarding sharps to their supervisors to ensure proper post-exposure prophylaxis (PEP) is administered
Infection Control
- Protective equipment like gloves, masks, and gowns should be available for use in healthcare settings
- Personnel should wear gloves when in contact with mucous membranes to prevent transmission of infection
Nosocomial Infections
- Nosocomial infections are infections acquired in a healthcare setting, such as urinary tract infections and surgical wound infections
- Influenza is not typically considered a nosocomial infection
Cycle of Infection
- The 'portal of entry' refers to the way a pathogen enters the body
- Iatrogenic infection refers to an infection caused by medical treatment or procedures
- The 'reservoir' in the Cycle of Infection involves the presence of a pathogen capable of causing disease
- All six elements of the Cycle of Infection must be present for infection to occur: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host
Personal Protective Equipment (PPE)
- Gloves should be removed and discarded when contaminated or when leaving a patient's room
- Masks should be worn when in close proximity to patients with airborne infections or when performing aerosol-generating procedures
- Protective long sleeve gowns are worn to prevent skin and clothing contamination
- Masks must securely cover the nose and mouth to prevent inhalation of airborne pathogens
- A fit-tested N95 mask is required for procedures like intubation and bronchoscopy
- Reverse isolation is typically practiced in healthcare settings when caring for immunocompromised patients
- Hand hygiene is a crucial step healthcare workers must take to prevent disease transmission
Nursery Precautions
- Health care workers should scrub their hands with antibacterial soap for at least 30 seconds before working with infants
- Materials contaminated by blood or body fluids should be properly cleaned and disinfected before discarding
- A medical radiation technologist (MRT) should report to their supervisor if they suspect or have an infection before entering a nursery
