FUNDAMENTALS FINAL EXAM Flashcards
standard precautions
Prevent and control transmission of diseases that can be acquired by contact it with blood, body fluids, non-intact skin, and mucous membranes.
isolation precautions
Protect patients, their families, other visitors, and healthcare workers from spreading germs across a healthcare setting.
Contact isolation
Direct and indirect contact with patients and environment.
Droplet isolation
Diseases that are transmitted by large droplets expelled into the air.
airborne isolation
transmitted by smaller droplets. 3 ft, and can remain in air for a longer amount of time.
Gowns
prevent soiling clothes (infected material, blood or bodily fluid)
Masks
Respiratory protections (blood, bodily fluids) airborne.
Protective eyewear
when performing procedures that splash or splatter (large abdomen wound or insertion)
Gloves
help prevent transmission of pathogens by indirect or direct contact.
What is the chain of infection
- Infectious agent or pathogen.
- Reservoir
- Portal of exit
- Mode of transmission
- Portal of entry
- Host
Infectious agent or pathogen
bacteria, viruses, fungi, and protozoa.
Reservoir
places in the environment where the pathogen lives. (people, animals, insects, medical equipment).
Break the chain by sterilizing, cleaning, pest control.
Portal of exit
after microorganisms grow they find the portal of exit, so they are able to enter another host and cause disease (mucus, gi tract) You can break this chain by washing your hands, personal protective equipment, control of splatter, and waste disposal.
Mode of transmission
direct, indirect, droplet, airborne, vehicles, vector. You can break the chain by hand hygiene, PPE, food safety, isolation.
Portal of entry
enter the body in the same route as exiting (hand hygiene, PPE, personal hygiene, first aid)
Host
susceptible host to spread disease (immunizations, treatment of underlying disease, health insurance, patient education)
Risk factors for developing infections
Age, nutritional status, stress, and disease process.
Medical asepsis
(clean technique) reduces number of organisms present and prevent transfer
Surgical asepsis
(sterile technique) prevents contamination of an open wound. Maintains sterile field for surgery.
Community acquired disease
diseases developed outside the hospital. Patient acquires disease within 2 days of admission.
Hospital acquired disease
Diseases developed from the hospital. Lower respiratory tract infections. Patient acquires disease two day after discharge.
Localized infections
wound infection.
symptoms include: pain, tenderness, warmth, redness.
Systemic infections
affects entire body. Can become fatal if undetected and untreated.
Fowler Position.
45-60 degrees, patient head slightly elevated.
High fowlers
When head of bed needs to be elevated as possible. Ideal for excretion, help patient breathe, swallowing of food.
Semi Fowlers
During labor, receiving food through a tube.
Low fowlers
optimal for patients rest.
Supine position
resting on back. used in surgeries.
Prone position
used in surgeries. Laying on stomach.
Side lying
Patient rests on side (weight on hip and shoulder)
Sims position
places weight on anterior illeum, humerus, and clavicle.
Therapeutic effects and complications of bed rest
-theraputic effects: lots of rest, decrease cardiac and oxygen
Complications: SKIN BREAKDOWN, PRESSURE ULCERS. collapse of alveoli, decreased metabolism rate, fluid, electrolyte and calcium imbalance, inflammation of the lung from stasis and pooling of secretions, drop of bp greater than 20mmhg in systolic, muscle effects, skeletal effects, disuse, osteoporosis, joint contracture, footdrop,
Safety interventions when transferring and using a lift:
-make sure patient is secured
-if patient is too heavy get another nurse in there with you
-if patient starts to fall, slowly take them to the ground
Make sure breaks are on
Interventions to prevent complications of immobility
- constantly rotate patient to lessen the chance of skin breakdown
- keep them entertained so they don’t go into depression
- perform assessments of body alignment
- excersise in bed
different types of exercise
isotonic, isometric, aerobic
isotonic
muscles shorten to produce a muscle contraction to have movement (walking)
Isometric
change in muscle tension but no change in muscle length and no movement (gluteal setting, quad setting; squeeze and relax glutes)
aerobic
using oxygen to do an activity (running)
Isokinetic
includes variable resistance to movement (machines provide resistance to movement as joint goes through full ROM)
Complete bed bath
bath administered to totally dependent patient in bed
Partial bath
bed bath that only bathes parts that would be uncomfortable if unbathed. Face, hands, armpits, perineal area. Could be back rub too.
bag bath
has moistened towels with cleaning solution, easy, reduced time bathing, and patient comfort is better.
oral care
brush teeth if needed or use swabs.
clean dentures on a regular basis, remove and night and make sure to keep them covered in water.
Perineal care
male- inner to outer meatus. Move inner to outer.
Female- outer (2) Then inner (2). swipe down middle
eye care
wash with clean moistened wash cloth.
different section of washcloth each time.
principles of making an occupied bed
-patient is not able to move out of the bed so therefore you have to change the linens while patient is in bed. Especially if linens are soiled.
Potential cause of pressure ulcers
skin breakdown (patient needs to be turned every two hours). -pressure, friction, shearing.
stage I pressure ulcer
area is red and there may be a little pain but no open wound
stage II pressure ulcer
Skin breaks open, wears away, and forms an ulcer between dermis and epidermis. Shallow crater.
Stage III pressure ulcer
Check for undermining. ulcer gets bigger and extends to fat.
stage IV pressure ulcer
Pressure sore is very deep, reaches muscle tissue and bones. Extensive damage may occur.
