ASSESSMENT TECHNIQUES AND THE CLINICAL SETTING HEALTH ASSESSMENT TEAM Learning Objectives • At the end of the discussion students will be able to: • differentiate between physical examination techniques • understand rational between various examination techniques • understand how to apply the techniques of physical exam in terms of sequencing The Physical Examination • The health history provides the subjective data for health assessment • The physical examination provides the objective data • Together, the complete health history and the comprehensive physical examination comprise data base and represents the Assessment Phase of the Nursing Process Requirements • Examiner must develop technical skills and a knowledge base • Technical skills are the tools you use to gather the data • You will relate that data to your knowledge base and to your previous experience (critical thinking) Look “FOR” rather than “AT” • German poet Goethe (18th century) “We see only what we know” To recognize a significant finding, you need to know what to look for You need to know what findings you should expect inspect, palpate, percuss and auscultate You need to know ‘normal’ in order to know that something is abnormal PE Skills • What are the techniques or skills requisite for conducting the physical examination? • In what order are these skills performed? • What is the one body system exception? Why? I- INSPECTION • Concentrated watching • Whole person, then each • • • • body system MUST inspect!!!! Begins at moment you meet the patient “General Survey” Train yourself not to rush; confine hands in your pocket Compare one side of body to the other I- INSPECTION • Guidelines for Effective Inspection • Be systematic • Fully expose the area to be • • • • inspected • cover other body parts to respect the client's modesty Use good light, preferably natural light. Maintain comfortable room temperature. Observe color, shape, size, symmetry, position, and movement Compare bilateral structures for similarities and differences. Umbilical Hernia HEPATOMEGALY ASCITES Cyanosis of Nailbeds Same umbilical hernia while patient performs valsalva maneuver OBESE ABDOMEN II- PALPATION • Confirm points you noted during inspection • Applies your sense of touch: • Texture • Temperature • Moisture • organ location • Size • swelling • Vibration • Pulsation • Rigidity • Crepitation • lumps, masses and pain Palpation Techniques • • • • Slow and systematic Calm, gentle approach Warm hands Identify tender areas; palpate them last • Light palpation • depress the skin about 1cm • Deep palpation • push down about 5-8cm • Bimanual palpation 10 Bimanual palpation •requires the use of both hands to envelop or capture certain body parts or organs such as the • kidneys, uterus, or adnexa PALPATION •Palpation uses the sense of touch •Ask the Client for permission first •explain to your client what you intend to examine •Establish client trust with being professional •Please remember to use warm hands •Any tender areas should be palpated last Palpation: Specific Uses for particular parts of the hand • What parts of the hands are used for • Fingertips • best for fine tactile discrimination, as of skin texture, swelling, pulsation, and determining presence of lumps assessing: Tactile discrimination, swelling, pulsation, presence of lumps????? Detecting the position, shape, and consistency • A grasping action of the fingers and of an organ or mass????? thumb • to detect the position, shape, and Temperature?????? consistency of an organ or mass Vibration??????? • The dorsa (backs) of hands and fingers • best for determining temperature because the skin here is thinner than on the palms • Base of fingers (metacarpophalangeal joints) or ulnar surface of the hand • best for vibration III- PERCUSSION • • • • • What is percussion? Why is it done? How is it done Why not use X-ray instead? Why are short nails imperative? • What is Direct Percussion? Where? • What is Indirect Percussion? Where? III- PERCUSSION •Percussion is the striking of the body surface with short, sharp strokes •in order to produce palpable vibrations and characteristic sounds •It is used to determine: • the location, size, shape, and density of underlying structures •To detect the presence of air or fluid in a body space •To elicit tenderness •Note: •When examining Abdomen •you auscultate first followed by percussion then palpation Stationary Hand •Hyperextend the middle finger (pleximeter) and place distal phalanx firmly against the patient’s skin •Avoid ribs and scapulae •Percussing over bone yields no data •always dull •Left rest of hand off patient’s body or resting hand will damper the sound Striking Hand • Middle finger of dominant hand (plexor) • Action in wrist • Must be relaxed • Bounce middle finger off stationary finger (pleximeter) • Aim for just under nail bed at DIP joint • Percuss 2 times • Maintain technique and move from side to side • Body thickness may require more force Types of Percussion 1.Direct Percussion: •Percussion in which one hand is used •striking finger of the examiner touches the surface being percussed •Sinuses, infant’s thorax 2. Indirect Percussion: • Percussion in which two hands are used • the plexor strikes the finger of the examiner's other hand • which is in contact with the body surface being percussed • More common Types of Percussion 3. Blunt Percussion: • Percussion which the ulnar surface of the hand or fist is used in place of the fingers • to strike the body surface, either directly or indirectly CVA Tenderness Percussion Sounds Basic Principle •Structures with more air (lungs) •produce a louder, deeper, and longer sound because it vibrates more freely •Solid, more dense organs (liver) •gives softer, higher, a shorter sound because it does not vibrate as easily •Sound depends on nature of underlying structure and thickness of body wall you are examining IV- AUSCULTATION •Auscultation is listening to sounds produced inside the body •include breath sounds, heart sounds, vascular sounds, and bowel sounds •It is used to detect the presence of normal and abnormal sounds •Assess them in terms of loudness, pitch, quality , frequency and duration •Note: •when examining Abdomen •you auscultate first followed by percussion then palpation What exactly are you listening for and what is its significance? 22 2 Sides of Stethoscope… Diaphragm • used for high pitched sounds • breath, bowel and normal heart sounds • hold firmly against skin • leave a mark Bell • used for murmurs or low pitched sounds • hold it lightly against the skin • If hold too tightly it will obliterate the low pitched sounds Successful Auscultation • Quiet room/setting • Keep room warm • Warm stethoscope (“Chandelier’s • • • • • • sign”) Wet down a hairy chest (crackles or rales) Never listen over clothing or hospital gown! Avoid your own “artifact” Learn sound you are supposed to be hearing Be patient with yourself…requires practice If need to listen longer or re-examine or have someone else listen…explain to the patient The Setting Warm, comfortable, quiet, private and well lit Natural daylight is best Both sides of patient should be easily accessible Exam Room Prepare all of your equipment Equipment •Platform scale with height attachment •Sphygmomanometer •Stethoscope with diaphragm and bell •Thermometer •Pulse oximeter (in hospital setting) •Flashlight or penlight •Otoscope/ophthalmoscope •Tuning fork •Nasal speculum •Tongue depressor Equipment • Pocket vision screener • Skin-marking pen • Flexible tape measure and ruler • Reflex hammer • Sharp object (split tongue blade) • Cotton balls • Bivalve vaginal speculum • Clean gloves • Materials for cytologic study • Lubricant • Fecal occult blood test materials Otoscope • Funnels light into the ear canal and onto the tympanic membrane • Use tip: • largest one able to comfortably fit into the ear canal Ophthalmoscope • Illuminates the internal eye structures • System of lenses and mirrors • Look through the pupil at the fundus (background) of the eye • Similar to looking out a peep hole or keyhole General Approach • Consider your anxiety and that of the patient • Explain what you are going to do • Ask for permission to touch the patient • Proceed in an orderly systematic manner • Begin with non-threatening aspects such as vital signs, height/weight, eye chart, etc • Concentrate: One system at a time! • Explain what you will be doing “tapping you on the back” • Do not be afraid to use a form/checklist and briefly document as you go along • Take opportunities to teach • Explain if something takes a longer time or if you need someone else to examine Developmental Consideration Older Patient Can sit; frail may need to be supine Arrange sequence to limit position changes Allow rest periods Do not rush; use head to toe sequence Use physical touch unless culturally contraindicated Don’t mistake changes in senses for confusion Developmental Consideration Ill Patient If in distress, alter position during exam May be necessary to examine the body areas appropriate to the problem: collecting a “mini data base” May return after distress subsides Precautions • Standard precautions • applies to blood, all body fluids except for sweat • non intact skin, and mucous membranes • Transmission based • for patients with documented or suspected transmissible infections • Designed to be used in addition to standard precautions • Airborne, droplet and contact • Wash hands before and after gloves, and between patient contacts The General Survey, Measurement, Vital Signs Learning Objectives • At the end of the discussion students will: articulate the purpose and significance of the general survey describe the elements of the general survey identify the significance of vital signs and their meaning related to the health history and physical examination What is the General Survey?
