Chapter 25 Health Assessment
Purposes of the Health Assessment• Establish the nurse-patient relationship.• Gather data about the patient’s general health status.• Identify patient strengths.• Identify actual and potential health problems.• Establish a base for the nursing process.
Two Components of a Health Assessment• Health history — focus on interviewing skills• Physical assessment — head-to-toe sequence, system
sequence
Factors to Assess During a Health History• Biographical data• Chief complaint• History of present illness• Past medical history• Family history• Lifestyle
Preparing the Patient for Physical Assessment• Consider the physiological and psychological needs of the
patient.• Explain the process to the patient.• Explain that physical assessments will not be painful
(decrease patient fear and anxiety).• Ask the patient to change into a gown and empty
bladder.• Answer patient questions directly and honestly.
Preparing the Environment for Physical Assessment• Agree upon a time for the assessment.
– The time should not interfere with meals, daily routines, or visiting hours.
• Patient should be as free of pain as possible.• Prepare the examination table.• Provide a gown and drape for the patient.• Gather the supplies and instruments needed for the
assessment.• Provide a curtain or screen if the area is open to others.
Equipment Used During a Physical Examination• Ophthalmoscope — visualizes the interior structures of the
eye• Otoscope — examines the external ear canal and tympanic
membrane• Snellen’s chart — screens for distant vision• Nasal speculum — visualizes the lower and middle
turbinates of nose• Vaginal speculum — examines the vaginal canal and cervix• Tuning fork — tests auditory function and vibratory
perception• Percussion hammer — tests deep tendon reflexes and
determine tissue density
Positions Used During a Physical Assessment• Sitting — used to take vital signs • Supine — allows relaxation of abdominal muscles• Dorsal recumbent — used for patients having difficulty
maintaining supine position• Sim’s — assessment of rectum or vagina• Prone — assessment of hip joint and posterior thorax
Positions Used During a Physical Assessment (continued)• Lithotomy — assessment of female rectum and vagina;
used for brief period only• Knee-chest — assessment of the rectal area; used for
brief period only• Standing — assessment of posture, gait, and balance
Techniques Used During a Physical Assessment• Inspection — assess size, color, shape, position, and
symmetry• Palpation — assess temperature, turgor, texture,
moisture, vibrations, and shape• Percussion — assess location, shape, size, and density of
tissues• Auscultation — assess the four characteristics of sound;
i.e., pitch, loudness, quality and duration
Characteristics of Masses Determined by Palpation• Shape• Size• Consistency• Surface• Mobility• Tenderness• Pulsatile
Types of Sounds Heard When Using Percussion• Flat — soft, e.g., thigh area• Dull — medium, e.g., liver• Resonance — loud, e.g., normal lung• Hyperresonance — very loud, e.g., emphysematous lung• Tympany — loud, e.g. puffed-out cheek
Characteristics of Sound Heard When Using Auscultation• Pitch — ranging from high to low• Loudness — ranging from soft to loud• Quality — e.g., gurgling or swishing• Duration — short, medium or long
General Survey• General appearance• Vital signs• Height and weight
Physical Assessment• Integument• Head and neck• Thorax and lungs• Cardiovascular and peripheral vascular systems• Breasts and axillae• Abdomen• Female and male genitalia• Musculoskeletal system• Neurological system
Purposes of Documentation• Identify actual and potential health problems• Make nursing diagnoses• Plan appropriate care• Evaluate patient’s responses to treatment
Nurse’s Role in Diagnostic Procedures• Assist before, during, and after diagnostic tests.• Be responsible for other activities associated with
diagnostic tests.• Witness the patient’s consent.• Schedule the test.• Prepare the patient physically and emotionally for the
test.• Provide care after the test.• Dispose of used equipment.• Transport specimens.
