Study Notes
Learning Outcome 1
- Reinfection occurs when a person who has had an infection becomes infected again.
- Barrier is a process that blocks the spread of bacteria.
- Precautions are protocols used to prevent transmission of contagious infective agents.
- Communicable describes anything that can be transferred from one person or place to another.
- Disinfectant is a chemical substance that kills microbes; used only on objects, not humans.
- Pathogen is a disease-causing bacteria.
- Cross-infection happens when infection is spread between individuals infected with different disease-producing microbes.
- Micro-organism is a living thing too small to be seen except with a microscope. It's synonymous with microbe and plays a role in various environments.
- Germicide is a substance that kills germs or microorganisms.
- Contaminate means to be made unclean, unsterile, and contain or be suspected of containing disease-producing microbes.
- Asepsis denotes the absence of disease-causing bacteria; a state of being infection-free.
- Bacteria are tiny units of living matter capable of causing disease by reproducing and multiplying.
- Infection represents an invasion of the body by a microbe capable of causing a disease when it reproduces and multiplies.
- Nonpathogenic refers to something that is not capable of producing disease.
- Medical asepsis involves the removal of microbes that are able to cause disease, using a clean technique.
- Carrier describes a person who shows no signs of illness but carries microbes that can spread to others.
- Antiseptic is a chemical substance or process that kills most microbes.
- Antiseptic is a chemical substance that inhibits the growth and reproduction of microbes but doesn't kill them, and is not toxic to humans.
Learning Outcome 2
- Pressure sores are also known as decubitus ulcers.
- Pressure areas can develop into decubitus ulcers.
- Not all clients in wheelchairs will develop a pressure area.
- Moisture does not cause the skin to become tough; it makes the skin more prone to breakdown.
- Obese clients are at risk for developing pressure areas.
- Thin clients are at risk for developing pressure areas.
- Our skin becomes less elastic as we age.
- Shearing force occurs when the skin is pulled in one direction while the underlying tissue remains stationary.
- Friction happens when the body slides down, and the skin is rubbed against the surface.
- Someone who is paralyzed may have decreased sensation to pain.
- Vitamin C is essential for skin growth and repair.
- Elderly individuals have slightly cooler skin than younger individuals.
- Turgor that takes a long time to return to normal can indicate dehydration.
- Wrinkles on bed linens are a concern as they can cause pressure sores.
- Do not massage a reddened area as it can damage the tissue further.
- Soap can dry and irritate the skin.
Learning Outcome 4
- Bedmaking involves handling bed linens properly to prevent the spread of infection.
- Body mechanics are crucial when making a bed.
- The three types of beds include:
- Occupied beds: The client remains in bed while the linen is changed.
- Unoccupied closed beds: The client will stay up for a while, and the bedsheets are pulled up to the pillow for later use.
- Unoccupied open beds: Used when the client is returning to bed shortly.
-
Bed positions:
- Flat: The bed is in the horizontal position with no raised head or foot (usual sleeping position).
- Low Fowlers: The head of the bed is raised 15-30 degrees (semi-sitting position).
- Semi Fowlers: The head of the bed is raised 30-45 degrees (higher semi-sitting position).
- High Fowlers: The head of the bed is raised 45-90 degrees (highest semi-sitting/sitting position).
- Trendelenburg: The head of the bed is lower than the foot of the bed.
- Reverse Trendelenburg: The head of the bed is raised higher than the foot of the bed.
Learning Outcome 6
- Edentulous describes a person who has no teeth.
- Dentition refers to the condition of one's teeth.
- Cavity is a hole in a tooth.
- Gingivitis is inflammation of the gums.
- Periodontal disease is a more serious condition that can develop if gingivitis is not treated.
- Tongue piercings can cause recession, which leads to gingivitis or periodontal disease.
- Consistent brushing will help decrease gum bleeding after a few days.
- Xerostomia refers to a consistently dry mouth.
- Multiple courses of antibiotics can put you at risk for thrush.
- Poor dental hygiene increases the risk of developing a heart condition.
