Final Flashcards
pandemic
new strain or virus effects greater number people on larger geographic scale
can cause- social disruption, economic loss and general hardship
epidemic
rapid spike # infected indivi in a localized area
outbreak
sudden rise # cases of an identified dis
R0 value
basic reproductive number
rate dis spreads through susceptible population
covid 19 incubation period
2-14 days
covid 19 symptoms
dry cough, SOB, loss taste or smell, myalgia, fatigue and fever
swiss cheese model of pandemic defense
each slice = guideline
if enough guidelines are in place most of all the holes will be covered
=reduce overall risk
covid 19 quarantine v isolation
quarantine- slows spread if you came into contact with an infected person
isolation= if you have the virus
hypothermia/hyperthermia
<95 and >104
bradycardia v tachycardia
< 60 bpm
> 100 bpm
hypo v hypertension
< 90/60
> 130/80
oxygenation measure of

med= clean (regular) sterile= cath, nicu, invasive procedures
HAI
ssi- surgical site infection
clabsi- central line ass. bloodstream infection
vap- ventilator ass pneumonia
only fluid gloves are not needed for
sweat
aseptic tech
all act. that prevent or break chain of infection
factors affecting personal hygiene
cult, socioeconomic class, spiritual practices, dev lvl, health state, personal pref
methods of hygiene
feeding, bathing, dressing/ grooming, toileting
oral care concerns
observe for dental caries, periodontal dis
oral care steps
toothbrush 45 degree angle, brush from gum line to crown, brush biting surfaces
floss- 18 in, 1-1.5 btw fingers
dysphagia
swallowing disorder incl oral cavity, pharynx, esophagus,or gastroesophageal junction
cause of dysphagia
always secondary to another dis
neuro event (stroke, injury spinal cord/ brain, ALS, parkinsons, multiple sclerosis
cancer, chemorad, meds, GERD, elderly
dysphagia symptoms
drooling, poor secretion management, fluid leaking from oral or nasal cavity, complaints food is “sticking”, pain when swallowing, gurgly sounding voice after eating, difficulty coordinating breathing and swallowing, extra time need to chew, weight loss/ dehydration, recurrent aspiration pneumonia
chin tuck or oral care
chin tuck not always work!
oral care important bc bac enters into lungs
dysphagia- common tip-offs
coughing, trouble swallowing, choking, drooling, frequent lung infections
oral care considerations- specific
chemo agents cause lesions, poor nutrit, diet, self care abilities, comatose, paralyzed, oral surgery
oral care- comatose
patient on side, head tilted forward, open mouth w/ pressure on bottom jaw
nutrition- considerations
swallowing ability, dev lvl, age, pregnancy, mental health, trauma, chronic dis, meds, religion/preference, economic factors, culture
nutrition- measuring intake types
24 hour recall, food diaries, food frequency, diet history
incentive spir-purpose
before surgery inc lung vol and venous return visual reinfor for deep b sustain max inspiration prevent/reduce atelectasis clear secretions, inc gas exchange
incentive spir- how
sit patient up, assess for pain, admin meds if needed, hold mouth piece and container w/ diff hands, inhale completely with mouth on hose, exhale normally without lips connected
sterile def
all path and microo destoyed
sterile fields
1inch around not sterile, pinch from center, fold over hands if moving, do not bend/ reach over
examples sterile procedures
cath, preparation inject meds, dressing changes
sterile gloving steps
cuffed end closest to self, unfold top crease then bottom crease, pinch under middle creases and pull out to expose gloves, use nondominant hand to grab cuff of dominant hand glove, pull on, use gloved hand to slide under folded cuff and put on non-dominant hand
measuring urine output- continent
have pat. pee in specimen hat, urinal or bed pan
measuring urine output- incontinent
drain urine into measuring device, do not touch spout to bag, wipe spout w/ alcohol before replacing
urinary catheters- types
intermittent urethral cath- (straight cath, used for short time to drain), indwelling urethral cath (continuous bladder drainage) suprapubic cath (long-term contin drainage) (surgically inserted, diverts urine from urethra)
foly cath- care
wash hands, clean area, encourage fluid intake, chart input and output every 8 hours, look for signs of infection (cloudy urine, chills), keep bag lower than bladder, educate self care and hygiene, change leg bags every 5-7 days
urinary diversion
creation of stoma, (sm intestine to skin) ileal conduit cutaneous ureterostomy (ureters attached to skin) continent urinary divers. (CUD)(pouch created in sm intestine)
posterior hip replacement precautions
no bending beyond 90 hip flexion, no crossing legs, turning toes in
anterior hip replacement precautions
no crossing legs, no turning toes out when leg is behind
total knee replacement precautions
no pillow directly under knees, bed locked flat, weight bearing as tolerat.
sternal precautions
no pushing/pulling w/ both arms, no arms above shoulders, no lifting
back precautions
no bending, lifting or twisting
WBAT
NWB
TTWB
weight bearing as tolerated
non weight bearing
toe touch of touch down weight bearing
five steps in nursing process
ADPIE asessing diagnosing planning implementing evaluating
characteristics of nursing process (SDIOU)
systematic dynamic interpersonal outcome oriented universally applicable
systematic
ordered sequence of act
dynamic
interaction and overlap of five steps
interpersonal
comm/ interaction with pat
outcome-oriented
nurse and pat work together to id outcomes
characteristics of assessment
ppcsfrr
purposeful, priorit, complete, systematic, factual, relevant, recorded standard manner
purpose of assessment
create database
id health problems, health status
makes diagn and planning easier
implementing
carrying out plan
evaluating
measuring extend outcomes achieved
diagnosing process explanation
analyzing pat data to id strengths, problems
*diff. than usual med diagnosis
assessing in relation to data
collecting, validating, and comm w/ pat
planning
id pat outcomes and plan interventions
nursing diag. format
problem, “related to”, etiology/cause, “as evidenced by”, defining characteristics
wound characteristics- open or closed
is the dermis visible?
ex. closed= hematoma (bleeding underneath skin)
wound characteristics- acute v chronic
chronic wounds take longer to heal
wound definition
integrity of skin or mucous mem. is broken/ no longer intact
asepsis used for wound care
clean/ medical and surgical (sterile)
nutrients needed for wound healing
protein and adeq. blood supply
wound healing- first phase I
hemostasis constriction followed by dilation immediately after tissue/skin injury platelets attract o/ cells exudate is formed= pain and swelling
wound healing- second phase II
inflammatory
lasts 4-6 days
macrophages present, ingest debris and attract fibroblasts
acute inflammatory response = pain, heat, erythema and edema
fatigue is common*
wound healing- third phase III
proliferation starts w/in 2-3 days of injury capillaries grow across wound thing layer epith cells forms new tissue growth (granulation) and scar formation
wound healing- fourth phase IV
maturation
begins 3-6 weeks after injury
collegen tissue dev.
wound remodeling
wound site factors that affect healing
pressure (interferes w/ blood supply)
desiccation (too dry)
Maceration (too moist)- inc bac. growth
edema (disrupts normal o2 and blood flow to wound)
infection (energy is diverted to immune response, not wound healing)
necrosis (tissue slough and eschar)
* dictate the difference btw a chronic and acute wound
general factors that affect healing
circulation and oxygenation
nutritional status- presence of protein, hydration
addit. chronic illnesses- alter immunes response
wound chara- baseline condition
immunosuppression- ex. aids, or autoimmune reaction
wound assessment- inspection
inspection
edges, location, size, depth, surr. tissue, drainage, type of closure
wound assessment- exudate types
type
serous- watery
sanguineous- bloody
serosanguineous- watery and bloody
