Test #1 Flashcards
(39 cards)
Diagnostic Reasoning
1) attending to available cues
2) formulating a diagnostic hypothesis
3) gathering data relative to tentative hypothesis
4) evaluating each hypothesis with new data to arrive at the final diagnosis
Priorities
1st level - emergent, immediate, life threatening, ABC’s
2nd level - urgent, necessitating prompt interventions, acute pain
3rd level - important, addressed after more urgent problems…teaching, lack of knowledge, resources
Collaborative - involves multiple professions, alcohol abuse, diabetes
Models of Health
biomedical model - health is the absence of disease
behavioural model - treatment of disease and preventions
Socioenvironmental Model - sociological and environmental aspects
purpose of the interview

Ten Traps of Interviewing
- providing false reassurance
- giving unwanted advice
- using authority
- using avoidance language
- engaging in distancing
- professional jargon
- using leading or biased questions
- talking to much
- interrupting
- using “why” questions
Non Verbal Cues
- physical appearance
- posture
- gestures
- facial expressions
- eye contact
- voice
- silence
- bodily exposure and touch
the complete health history
- biographical data
- source of history
- reason for seeking care
- current health or history of current illness
- past health
- family history
Functional Assessment (activities of daily living)
- self esteem
- activity/exercise
- sleep/rest
- nutrition/elimination
- interpersonal relationships
- spiritual resources
- coping and stress management
- personal habits (tobacco, alcohol)
- environmental hazards
- Occupational health
- intimate partner violence
Assessment Techniques (IPPA)
inspection
palpation
percussion
auscultation
Inspection
concentrated watching
general survey
compare sides (symmetry)
Palpation
can confirm details from inspection
- touch: texture, temperature, moisture, organ location and size, pain, tenderness, lumps, rigidity, crepitation
- slow and systemic: warm hands, start away from painful areas
- light palpation first (1-3cm): work in small concentric circles
- deep palpation second (5-7cm): avoid digging, intermittent is better than continuous
Fingertips - tactile discrimination
Dorsum - temperature
Base of fingers and ulnar surface - vibrations
bimanual palpation - hand over hand for deep palpation, cupping (duck bill)
Percussion
tapping skin palpable vibration and characteristic sounds direct percussion indirect percussion characteristics of percussion notes - resonant: lungs (air filled spaces) - hyperresonant: hyper inflated lungs - tympany: stomach (fluid filled spaces) - dull: solid organs, bones - flat: bones
Auscultation
diaphragm - high pitched sounds (respiratory, abdominal, cardiac sounds) Bell - low pitched (vascular sounds) clean stethoscope no friction on tubing never listen through gown/clothing wet hair to minimize 'noise'
Vital Signs - Normal Ranges (TPRBPSP02)
Temperature -oral: 35.8-37.3 -tympanic: 36.5-37.5 Pulse: 60-100 bpm Respiratory rate: 12-20 respirations per minute blood pressure: 120/80 oxygen saturation: >95% on room air pain assessment
Temperature
oral
tympanic
temporal
rectal (1 degree higher than oral and tympanic, accurate and definitive for kids)
armpit (not accurate, best for kids and babies)
diurnal variance: 1-1.5 degrees (normal change in variance throughout the day)
febrile - above 37.5 C (fever)
rigor - shaking cause cold
Pulse
rate (30 seconds x 2 or 60 seconds)
- normal range is 60-100
- bradycardia = <60
- tachycardia = >100
Force
- 0=absent
- 1=weak
- 2=normal
- 3=bounding
Apical Pulse - 5th intercostal space at midclavicular line
pulse deficit - mismatch between apical pulse and peripheral pulse
Respiration
normal = 10-20 bradypnea = <10 Tachypnea = >20
(oxygen saturation) Sp02
measure the amount of oxygen bound to hemoglobin
requires equipment
no nail polish or fake nails
can use on toes and pin of ear
Blood Pressure
systolic blood pressure - med surg, measures how much blood is going through the tube, diameter of the tube, flexibility of the tube
diastolic blood pressure - med surg
Mean arterial pressure - ICU, looks at the whole cardiac function
blood pressure equipment
stethoscope - bell
sphygmomanometer
- aneroid (manual)
- Oscillometric (automatic)
Sizing
- bladder of cuff encircles 80% upper arm circumference
- width of cuff = 40% circumference of upper arm
Measuring Blood Pressure
Stages
fully compressed = silence (120+)
partially compressed = korotkoffs sounds (80-120)
free flowing = silence (0-80)
stage 1 is where sound starts
stage 5 is where sound ceases
Auscultatory Gap - silence in the middle of korotkoffs sounds, not normal
hypertension/hypotension
systolic prehypertension=129 systolic stage 1 hypertension=139 systolic stage 2 hypertension=140+ diastolic hypertension=90 diastolic hypotension=60
