midterm Flashcards
nursing role in preoperative phase
Obtain health information
Determine pt’s expectations about procedure
Provide & clarify information about procedure
Assess pt’s emotional state & readiness
Provide discharge planning and postoperative teaching
preoperative assessment
before surgery to determine if there are any changes (baseline)
what is included in preoperative assessment
health assessment
history (medical conditions & current health challenges, previous surgeries, family history)
medications (herbal & vitamins)
substance use
allergies
purpose of preoperative screening
baseline, see if anything is happening to cause complications
common preoperative screening tests
Urine analysis, checking how the kidneys are working, UTIs,
chest xray (see if anything present that will make the surgery difficult),
CBC (complete blood count),
CPT (electrolytes and glucose),
INR PTT (how fast you can form clots) = important to know to determine if your body can clot to help the healing process,
ECG (checking out heart to make sure the heart is strong),
creatinine & gfr (tell us how the kidneys are functioning),
liver function tests
preoperative teaching
Nutrition (NPO – reduce the risk of aspiration & post-op nausea)(increase diet slowly),
breathing (deep breathing & coughing = important to facilitate lung expansion, encourages the gas exchange, and mucus movement, incentive spirometer, splinting to avoid damage incision),
grooming (special soap, shower, shaving if necessary, nails, polish, jewerly, dentures),
medications (what can they take day off – will be provided instructions),
pain control (what kind of pain they should expect, letting them know about pain management),
dressings & drains & tubes (what are they going to wake up with),
safety (call bell in reach, letting them know it may be difficult to get out of bed),
preoperative information (where they should park, where can family wait, how long it should take),
ambulation (compression stockings, leg exercises, mobilizing early = prevents the body from decom the muscles quickly)
informed consent
getting enough information to make a decision
aspects of informed consent
- voluntary consent
- capacity to consent
- properly informing pt
- advocating for pt
- barries/ethical complications: language barriers, refuses
intraoperative phase
multi-disipline team
postoperative phase
post anaesthesic care unit (PACU)
what is the PACU
unit where the pt is under close and constant observation to make sure they are returning to normal physiological functioning (VS machine & IV ready)
initial post operative assessment
airway (patent, adventitious sounds?)
breathing (regular & easy)
circulation (VSS, warn & dry to touch, oozing/bleeding at site)
disability/neurological (LOC/cognition/orientation)
neurological postoperative complications
emergence delirium, delayed awakening
emergence delirium
acute confusion state during recovery from anesthesia
CAM test
safety
neurological assessments
bedrails
respiratory postop complications
obstruction, hypoxemia (atelectasis, pulmonary edema, aspiration), hypoventilation (breathing that is too shallow or too slow to meet the needs of the body = body’s carbon dioxide level rises.
cardio postop complications
hypotension, hypertension, dysrhythmias, DVT/PE, syncope, fluid & electrolyte imbalances (hypokalemia, overload)
GI postop complications
N & V (PONV = postop nausea & vomiting)
slowed GI motility
altered patterns of food intake
urinary postop complications
low urine output
acute urinary retention
integumentary postop complications
impaired wound healing
infections
temperature post op complications
hypothermia, fever
pain & discomfort postop
presence of internal devices, mobilization, incision
discharge instructions
Care of wound site & dressings
Bathing recommendations
Activities allowed & prohibited
Dietary restrictions or modifications
Symptoms to be reported
Follow-up care
purpose of MSE
overview of functioning, monitor changes over time, provides snapshot of how that person in that moment (holistic)
appearance
clothes, hair, tattoos, ethnicity, cultural background, piercings, age
behaviour
eye contact, gait, mobility, cooperation, attitude, dismissive, psychomotor activity, agitation
affect
physical representation of mood, reflection of thoughts & feelings (congruent/incongruent)
euthymic
as expected
speech
rhythm, volume, tone, pace
thought form
how they think
circumstantial
they eventually get to the point, give unnecessary details
tangential
never get to the point, keep talking about nothing to do with the point
flight of ideas
non goal directed, “takes off” from topic at hand, change topics quickly
loose associations
disintegration of meaningful connections between ideas occur, transitions b/w topics not logical connections b/w ideas
thought blocking
involuntary interruption of thought & speech
derailment
speech begins again after thought blocking
word salad
extreme form of loosened associations to the point the words have no connection to one another
thought content
what they are thinking
delusions
persecutory, grandiose, jealously, religious, obsession, phobias, ideas of reference
ideas of reference
false beliefs that random or irrelevant occurrences in the world directly relate to onesel
perception
hallucinations (auditory, tactile, visual, gustatory, olfactory, somatic)
cognitive functioning
memory, LOC, concentration, attention span, orientation
insight/judgement
insight = if they get whats going on, they understand the situation they are in
judgement = decision-making
shock
failure of circulatory system to maintain adequate perfusion of vital organs
if there is inadequate tissue perfusion…
decreased O2 at cellular level –> switch from aerobic to anaerobic cellular metabolism –> accumulation of waste products –> cell death
what is the waste prodcut that builds up for inadequate tissue perfusion
lactic acid
tissue perfusion means
continuous delivery of an adequate blood supply containing oxygen, nutrients, and hormones to the body’s tissues and organs
different shocks
cardiogenic, hypovolemic, septic, anaphylactic, neurogenic
which shocks are considered distributive
septic, anaphylactic, neurogenic
distributive means
maldistribution of blood flow
fluid is in the wrong space, not in the vessels, total fluid volume is normal just in wrong space
distributive shock causes
widespread vasodilation
cardiogenic shock
happens when your heart cannot pump enough blood and oxygen to the brain and other vital organs
causes of cardiogenic shock
MI, blunt force trauma, cardiomyopathy
clinical manifestations of cardiogenic shock
CV: tachycardia, hypotension, narrowed pulse pressure, cool clammy, pallor, peripheral hypoperfusion
RESP: tacypnea, pulmonary congestion
RENAL: decreased urine output, Na H2O retention (edema)
NEURO: anxiety, LOC, confusion
hypovolemic shock
loss of intravascular fluid volume by either ABSOLUTE VOLUME LOSS or RELATIVE VOLUME LOSS
remaining volume unable to meet O2 needs
absolute volume loss examples
external bleeding, vomiting, diarrhea, excessive sweating
relative volume loss examples
internal bleeding, fluid shifts, burns
clinical manifestations of hypovolemic shock
CV: tachycardia, hypotension, cool clammy, peripheral hypoperfusion
RESP: tachypnea
RENAL: decreased urine output
NEURO: agitation, confusion, anxiety, LOC
body can compensate for up to 15%, greater than 30% body begins to fail (T/F)
TRUE
neurogenic shock
massive vasodilation without SNS activation, blocked
blocked = no increase HR
can occur within 30 mins of injury last up to 6 weeks
clinical manifestations neurogenic
hypotension, bradycardia, inability to regulate temp = hypothermic
anaphylactic shock
IMMUNE SYSTEM OVERLOAD, IMMEDIATE REACTION CAUSING LEAKING FROM VASCULAR SPACE TO INTERSTITIAL SPACE
hypersensitivity reaction to a sensitizing substance (immediate reaction causes massive vasodilation, release of vasoactive mediators, increase in cap permeability == fluid leaks from vascular space into interstitial space
clinical manifestations for anaphylactic shock
NEURO: anxiety & sense of impending doom
AIRWAY: swelling, swollen tongue
BREATHING: tachypnea, dyspnea
CIRC: hypotension, tachycardia
SKIN: rashes, hives
GI: N & V
what needs to be involved to be classified as anaphylaxis
2 systems (neuro & skin)
septic shock
presence of sepsis with hypotension despite resuscitation and resulting hypoperfusion
infections that can lead to sepsis
UTI, pneumonia, wounds
clinical manifestations of sepsis
RESP: tachypnea
CV: tachycardia, hypotension, warm & flush THEN cool & mottled, initially have fever then become cool
GU: decreased urine output
NEURO: confusion, altered mental status
change in LOC is #1 manifestation in elderly people regarding sepsis
TRUE
compensatory stage of shock
compensatory mechanisms maintain BP & cardiac output within a normal to low range
norepinephrine & epi released, vasoconstriction & tachycardia, BP & perfusion to vital organs maintained
progressive stage of shock
prolonged vasoconstriction (SNS working hard)
reduced supply O2 blood
switch to anaerobic metabolism & build up of lactic acid
microcirculation dilates
decrease BP, venous return
tissue hypoxia
refractory stage of shock
celllular ischemia & necrosis progresses = organ failure & death
cycle of inadequate tissue perfusion is not interrupted
medical management for shock
oxygen & ventilation (admin O2 & patent airway)
fluid resuscitation (admin IV fluids, monitor BP & output, monitor cardiovascular system)
drugs (vasopressors)
nutrition (enteral & parenteral)
medical management for cardiogenic shock
- thrombolytic therapy
- angioplasty/CABG/IABP
- admin inotropes & vasopressors
medical management of hypovolemic
fluid resuscitation (maintain BP & output)
treat cause
medical management of septic
blood cultures
IV antibiotics & fluid resuscitation
monitor glucose & insulin (hyperglycemia)
monitoring labs (lactic acid)
neurogenic shock medical management
spinal stability
admin vasopressors & atropine
treatment dependent on cause
