Definition of TermsDefinition of Terms

1. Final diagnosis: scientific method of determining and identifying a patient's condition through evaluation of the health history, PE, laboratory tests, and diagnostic procedures

a. Often simply called the diagnosis (dx)


Definition of Terms, cont. Definition of Terms, cont.

2. Clinical diagnosis: intermediate step in the determination of a final diagnosis

a. Obtained through evaluation of health history and PE (without laboratory and diagnostic tests)

b. Outside laboratories provide space on laboratory request: to specify clinical diagnosis

c. Once physician has analyzed test results: final diagnosis can usually be established



3. Differential diagnosis: two or more diseases may have similar symptoms

a. Determines which disease is causing the symptoms so that a final diagnosis can be made

b. Example: “Strep” throat and pharyngitis have similar symptoms• Differential diagnosis is made by strep test

4. Prognosis: probable course and outcome of a patient's condition and the patient's prospects for recovery



5. Risk factor: physical or behavioral condition that increases the probability that an individual will develop a particular condition

a. Includes:• Genetic factors• Habits• Environmental conditions

b. Does not mean the disease will develop• Only that chance is greater of developing it• Example: Smoking is a risk factor for lung cancer and

heart disease

6. Acute illness: characterized by symptoms that have a rapid onset

a. Usually severe and intense

b. Subside after a short time• Example: influenza

7. Chronic illness: characterized by symptoms that persist for more than 3 months

a. Patient shows little change over a long time• Examples: diabetes, hypertension, emphysema



8. Therapeutic procedure: a procedure performed to treat patient's condition with the goal of eliminating it or promoting as much recovery as possible

a. Example: administration of medications

9. Diagnostic procedure: performed to assist in the diagnosis of a patient's condition

a. Examples: electrocardiography, x-ray examination

10.Laboratory testing: the analysis and study of specimens obtained from patient to assist in diagnosis and treatment of disease

Preparation of the PatientPreparation of the Patient

1. MA's responsibility: prepare the patient for PEa. After escorting patient to examining room

• Identify the patient by name and date of birth

b. Take vital signs

c. Measure height and weight

d. Explain purpose of examination and answer questions

e. Apprehension can be reduced by:• Address patient by name of choice• Have a friendly and supportive attitude• Speak clearly, distinctly, and slowly


Preparation of the Patient, cont.


f. Ask patient if he needs to empty the bladder before examination• Makes examination easier for physician to perform and

more comfortable for patient • If urine specimen is needed: patient is asked to void

g. Instructions for disrobing should be specific• Clothing that should be removed• Where to place clothing

– Instructions for putting on gown and location of gown opening




h. Disrobing facility should be comfortable and private

i. MA should have patient's medical record available for review by the physician• Use designated location for medical record

a. Shelf next to examining room door or chart holder • Follow HIPAA privacy rule to protect patient's health info

j. Help patient on/off the examining table for safety


Measuring Weight and HeightMeasuring Weight and Height

1. Mensuration: process of measuring 2. Change in weight may be significant in:

a. Diagnosis of patient's condition

b. Prescribing treatment

3. Underweight/overweight patients on diet therapy program:a. Should have weight taken regularly to determine

progress


Measuring Weight and Height, cont.


4. Prenatal patients weighed at each prenatal visit to:

a. Assess fetal development & mother's health

5. Adult weight is measured at each office visit

6. Adult height usually only measured:a. First office visit

b. Complete PE




7. Children weighed and measured at each office visit to:a. Observe pattern of growth

b. Calculate and determine medication dosage

8. Height and weight are compared against a standardized chart:a. Determines if patient falls within normal

limits




9. Guidelines for Measuring Ht/Wt:a. Weight: Using an upright balance scale

• Provide privacy for patient – Many patients are self-conscious about having

weight measured • Balance scale

– If scale not balanced: measurement will be inaccurate

– Scale is balanced when upper and lower weights are on zero and indicator point comes to a rest at center of balance area


Balance the Scale Balance the Scale

Balance the Scale




• Assist the patient– Assist patient on and off the scale platform – Platform moves slightly: may cause patient to

become unsteady• Obtain an accurate weight

– Ask patient to remove shoes– Measure weight with patient in normal clothing– Ask patient to remove heavy outer clothing




• Interpret calibration markings accurately

– Lower calibration bar: divided into 50-pound increments




– Upper calibration bar is divided into pounds and quarter pounds

1) Longer calibration lines: indicate pound increments

2) Shorter calibration lines indicate quarter-pound and half-pound increments


Measuring WeightMeasuring Weight




• Determine patient's weight correctly– Add the measurement on lower

scale to measurement on upper scale

– Round results to nearest quarter pound

– Occasionally weight may need to be converted to kilograms (metric unit)

1) May be required to determine medication dosage

2) 1 kg = 2.2 pounds

3) To convert pounds to kg: Divide the number of pounds by 2.2




Height: Using an upright balance scale

• Do not place patient on scale in a forward position– Measuring bar could fall

into patient's face when patient steps off scale

• Determine the calibration markings accurately– Calibration markings are

divided into either:

1) Inches

2) Feet and inches


Measuring HeightMeasuring Height




• Read the measurement correctly

– Read the measurement at the junction of the stationary calibration rod and the movable calibration rod




– If patient's height is less than the top value of the stationary calibration rod

1) Read the measurement directly on the stationary rod

a) On most scales: highest calibration on stationary rod is 50 inches

b) Patients with a height of 50 inches or less will have their height read directly on stationary rod


Measuring HeightMeasuring Height




• Record the height measurement correctly.

– Record height measurement in feet and inches.

– If the scale is calibrated in inches:

1) Convert the reading to feet and inches: divide the number of inches by 12

2) Example: Height measurement of 60 inches is recorded as 5 feet (60 inches divided by 12 equals 5)


Positioning and DrapingPositioning and Draping

1. Correct positioning of the patient facilitates the examinationa. Permits better access to part being

examined

b. Sitting: Examination of the head, neck, chest, upper extremities; measure vital signs


Sitting PositionSitting Position

1. Examination of the head, neck, chest, upper extremities; measure vital signs


Supine PositionSupine Position

Supine: Examination of head, chest, abdomen, extremities• Not a

comfortable position for patients with:– Respiratory

problems

– Back injury

– Low back pain


Prone PositionProne Position

Prone: Examination of back; assess extension of hip joint


Dorsal Recumbent Position Dorsal Recumbent Position

Dorsal recumbent: Vaginal and rectal examinations, insertion of urinary catheter, examine the head, neck, chest and extremities of patients who have difficulty maintaining supine position • Bending of legs is

more comfortable for some patients


Lithotomy PositionLithotomy Position

Lithotomy: Vaginal, pelvic and rectal examinations


Sims Position Sims Position

Sims: Used to examine the vagina and rectum, to measure rectal temperature, to perform a flexible sigmoidoscopy, an to administer an enema


Knee-Chest Position Knee-Chest Position

Knee-chest: Examine the rectum, perform a proctoscopic examination


Fowler’s Position Fowler’s Position

Fowler's: • Examine upper

body of patients with cardiovascular and respiratory problems – Easier for these

patients to breathe in this position

• Draw blood from patients likely to faint


Positioning and Draping, cont. Positioning and Draping, cont.

Position used depends on type of examination being performeda. More than one position may be used

b. Explain position to patient and assist them into it

c. Take patient's endurance and degree of wellness into consideration• Weak or ill patient may not be able to assume a position

d. Do not keep patient in uncomfortable positions longer than necessary

e. Let the patient rest before getting off the examining table

f. Assist patient off table to prevent falls


Positioning and Draping, cont. Positioning and Draping, cont.

4. Draping provides modesty, comfort, and warmtha. Only part being examined should be

exposed

5. Gowns and drapes are made of paper or cloth


Inspection Inspection

Inspection: The process of observing a patient to detect the signs of disease• Observe patient for:

– Color

– Speech

– Deformities

– Skin condition

– Body contour and symmetry

– Orientation to the surroundings

– Body movements

– Anxiety level


Palpation Palpation

b. Palpation: The process of feeling with the hands to detect the signs of disease • Helps verify data obtained from inspection• Patient's verbal and facial expressions are observed• Used to determine:

– Placement and size of organs– Presence of lumps– Pain– Swelling– Tenderness

• Examples of palpation

– Breast examination, measuring radial pulse


Percussion Percussion

c. Percussion: The process of tapping body and listening to the sounds produced to detect the signs of disease• Used to determine:

– Size, density, location of organs• Example: examination of lungs and abdomen

1) Dense structures: produce a dull sound (liver)

2) Empty or air-filled structures: produce a hollow sound (lungs)


Percussion, cont.Percussion, cont.


Ausculatation Ausculatation

d. Auscultation: The process of listening with a stethoscope to the sounds produced within the body to detect the signs of disease• Used to:

– Listen to heart and lungs

– Measure blood pressure
