MIDTERM Flashcards
Chain of infection
- pathogen i.e., common cold virus
- reservoir i.e., people
- exit of reservoir i.e., out of mouth via saliva
- transportation i.e., sneeze/cough, speech, hands…
- portal of entry i.e., eyes, mucous membranes …
- susceptible host i.e., anyone
routine precaution “standard” and PPE
For ALL patients regardless of diagnosis or presumed infectiousness when handling:
* All body fluids, secretions and excretions except sweat
* Blood
* Non-intact skin
* Mucous membranes
PPE: gloves, gown, mask; eyewear as needed
isolation precaution - contact
germs are on surface of patient
PPE: gloves and gown
isolation precaution - droplet
germs are in large droplets in air within 1-2 m of patient. germs can survive in environment away from patient.
PPE: gown, gloves, mask, eyewear within 2m of patient
isolation precaution - airborne
germs are suspended in tiny air particles
PPE: N95 mask
donning
- hand hygiene
- gown
- mask
- eyewear
- gloves
doffing
- gloves
- hand hygiene
- gown
- hand hygiene (2m away from patient)
- eyewear
- hand hygiene
- mask
- exit room and hand hygiene
10 risk factors for falls (older adults)
- change in vision
- change in hearing
- change in mobility
- changes in reflexes
- genitourinary changes
- unfamiliar environment
- uneven/broken pavement
- medications
- dizziness and vertigo
- postural instability
Henrich II Fall Risk Model
used to determine potential risks.
score greater than 5 = high risk of falling
10 ways to prevent falls as a nurse
- using Henrich II Fall Risk Model
- call bell instruction
- fitted shoes for patient
- uniform stair sizes
- proper lighting
- proper handrails
- elevated toilet seat with armrests
- secure power cords along baseboard
- supervising patients who are confused
- placing tables near patients to avoid reaching over
5 SAFTEY CHECKS
- braked are on
- bed is in lowest position
- call bell is in reach
- side bars/ rails are up as needed
- personal belongings are in reach
seizure
- close curtain for privacy
before : pillows on bed and available,
position bed low, 2 side rails up, padded
side-rails and headboard (if possible)
during : ensure safety of environment, put
pillow under head, do not put anything in
their mouth, put bed rails up with padding,
provide privacy, if able – turn patient to
side-lying position, loosen tight clothing
(ties, strings etc.), time the seizure
sleep protocol
- reduce the amount of noise i.e., close doors/ windows
- dim lights
- announcement on PA that sleep will commence soon and minimize noise
- turn on white noise machine
- round for quietness - ask patient if they would like eye mask/ earplugs
deconditioning - metabolic/ gastrointestinal
- peristalsis decreases, fluid intake and appetite decrease
- difficulty passing stool
- edema
- electrolyte imbalance - calcium
respiratory
- decreased lung expansion and a decrease in gas exchange
- pulmonary secretions begin to pool
- atelectasis = collapse of alveoli
cardiovascular
- decreased cardiac output
- orthostatic hypotension = drop in BP
- heart works faster and less efficiently
- thrombus = materials attach to the inside of a vein
- embolus = a dislodged thrombus that travels through the circulatory/ respiratory system
musculoskeletal
- reduced muscle mass and impaired joint mobility
- decreased endurance as the patient
osteoporosis = loss of bone mass
joint contracture = fixation of a joint
foot drop = inability to dorsiflex due to nerve damage
urinary elimination
kidneys and ureters are at a level position, urine must enter ureters unassisted by gravity
- increased rate of UTIs and renal calculi
intergumentary
increased risk for pressure injuries
- prolonged ischemia (decreased flood flow) can result in a pressure injury
- inflammation over a bony prominence ex. scapulae, elbows, coccyx, heels
ROM
done to prevent joint contracture and reducing hazards of immobility
- active = patient does it
- passive = nurse moves each joint
pressure ulcer development - pressure intensity
minimal pressure required to collapse capillary. tissue ischemia or reduction of blood flow can occur when there is a prolonged period
pressure ulcer development - pressure duration
low pressure over a long period of time and high intensity pressures over short periods of times both cause tissue damage
- extended periods of time can occlude blood flow and nutrients, contributes to cell death
pressure ulcer development - tissue intolerance
the ability of tissue to endure pressure depends on the integrity of the tissue and the supporting structure
- factor of shear, friction, and moisture affect the skins ability to tolerate pressure
why are older adults at risk for pressure injuries (4)
- impaired mobility
- impaired sensory perception
- alteration in level of consciousness
- nutrition
