Physical Exam: Breasts

I. Inspection (Performed with client in lying, sitting or standing position)

• Size: Vary from convex to pendulous
• Symmetry: (The breast in the same side as your dominant hand is commonly larger than the other)
• Skin: Color, venous pattern, possibly a few hairs around areola
• Alterations:

1. retractions
2. dimpling
3. lesions
4. edema
5. inflammation

• Alterations with Pregnancy and Lactation:

1. enlargement of breasts
2. soreness of nipples during lactation
3. possible striae

• Nipple and areola:

1. size
2. color - ranges from pink to brown
3. shape - areola round or oval; nipples everted
4. symmetry - normally symmetrical
5. direction - normally nipples point in same direction
6. alterations - discharge; inverted nipples; bleeding

II.Palpation - Breast

• Lymph nodes: Normal findings - not palpable
• Breast tissue

Client should be in supine position with hand placed behind the neck.

• Methods of Examining Breast:

1. Clockwise or counterclockwise circling breast from nipple outward
2. Back and forth with fingers moving up and down each breast

• Consistency:

1. varies widely from person to person
2. Normal findings - dense, firm, and elastic

Physical Exam: Lungs

I. History: smoking, infections, pain, discomfort, dyspnea, activity intolerance, fever
II. Inspection


General Appearance: Respiration

• Breathing should be quiet and easy
• Respiration involves ventilation, diffusion, and perfusion of gases
• Factors influencing respirations: exercise, pain, anxiety, stress, anemia, posture, drugs (narcotics, amphetamine)
• Normal Rates of Respiration: Newborn - 35 to 40 breaths/minute; Infant - 30 to 50 breaths/minute; Toddler - 25 to 35 breaths/minute; Schoolage - 20 to 30 breaths/minute; Adolescent - 14 to 20 breaths/minute; Adult - 12 to 20 breaths/minute
• Depth: deep, normal, shallow
• Rhythm: regular, irregular; Normal Finding: regular
• Skin color
• Chest wall configuration: Normal Findings - symmetrical with bilateral muscle development; A-P Transverse Ration = 1-5:2-7

III. Palpation

• Feel for abnormalities such as masses, lesions, scars, swelling, crepitus, asymmetry
• Crepitus indicates air in subcutaneous space (in thoracic area, usually due to pneuomothorax)
• Vocal fremitus: Vibration felt when patient speaks; Increased over areas of consolidation

IV. Percussion

• Normal findings: resonance heard throughout lung fields

V. Auscultation

• Normal findings: quiet breathing throughout all lung fields
• Whispered pectoriloquy:

1. Client whispers "One, two, three" 
2. Over normal areas of the lung, only faint sounds are heard
3. Over consolidated areas, the words are more distinct

• Egophony:

1. Client says "E"
2. Over consolidated areas, the sound is a nasal "A"

VI. Alterations in Lung Function

• Cough
• Expectoration
• Dyspnea
• Bradypnea
• Tachypnea
• Hyperpnea
• Apnea
• Cheyne-Stoke respiration
• Kussmaul's breathing
• Biot's breathing
• Grunting
• Retractions
• Hemoptysis
• Pain
• Accessory muscle use
• Cyanosis
• Adventitious sounds
• Pursed-lip breathing:

1. Prolonged exhalation
2. Breathing out through puckered lips

• Pleural friction rub:

1. Grating sound produced by inflamed pleura rubbing together
2. Usually heard loudest over lower lateral anterior chest at end of inspiration

VII. Pediatric Differences

• Smaller, shorter, more pliable airways
• Underdeveloped supporting cartilage
• Above two factors increase the risk of obstruction due to mucus, edema or foreign body
• Flexible larynx more susceptible to spasm
• Immature immune system
• Incomplete myelinization
• Increased basal metabolic rate
• Decreased ability to mobilize secretions
• Less forceful cough

POINTS TO REMEMBER:

• Anemic patients may never become cyanotic
• Polycythemic patients may become cyanotic, even when oxygenation is normal
• Cough results from stimulation of irritant receptors, with implications of either acute or chronic etiology
• Cyanosis indicates decreased available oxygen. Etiology can be either peripheral or central in origin
• Wheezes indicates narrowing/inflammatory process of lower airways
• Stridor harsh sound produced near larynx by vibration of structures in upper airway. Classic "barky cough"
• Crackles or rales adventitious sounds, usually on inspiration and indicating inflammation

Physical Exam: Vasculature

I. Blood Pressure

• Reflects relationship between cardiac output, peripheral vascular resistance, blood volume and viscosity and arterial elasticity
• Factors influencing Blood Pressure: age, stress, race, drugs, diurnal (day-night) variations, gender
• Alterations in Blood Pressure: Hypotension, Hypertension
• Range of Normal Blood Pressure:

1. Child under age 2 weighing at least 2700 grams - use flush technique, 30-60 mmHg
2. Child over age two - 85-95/50-65 mmHg
3. School age - 100-110/50-65 mmHg
4. Adolescent - 110-120/65-85 mmHg
5. Adult - <130 mmHg systolic/ <85 mmHg diastolic

Common Mistakes during Upper Extremity Blood Pressure Checks

• Too wide bladder or cuff produces false low reading
• Too narrow bladder or cuff produces false high reading
• Cuff wrapped too loosely produces false high reading
• Deflating cuff too slowly produces false high reading
• Deflating cuff too quickly produces false low systolic and false high diastolic reading
• Inaccurate inflation level produces false low systolic reading
• Taking the blood pressure in lower extremities

Peripheral Blood Pressure Measurement in the Legs

• Use the popliteal artery behind knee as stethoscope ausculatory site
• Position the client prone or sitting with knees slightly flexed
• Use wide, long cuff; wrap it so that the bladder is over the posterior aspect of midthigh
• Systolic blood pressures in legs are 20-40 mmHg higher than in the brachial artery
• Diastolic pressure in the legs is about the same as in the brachial artery

II. Internal Carotid Arteries in the Neck

• Palpate each separately along margin of sternocleidomastoid muscle
• Normal findings: strong thrusting pulse
• Auscultate both sides
• Normal findings: no sound heard
• Constriction cause bruit

III. Jugular Veins

• Client in supine position with head elevated at 45 degrees
• Normal findings: pulsations not evident
• Jugular Venous Pressure (JVP): not to exceed 3 cm above level of sternal angle

• Precipitating factors
• Aggravating and alleviating factors
• Lifestyle factors: swimming, musician
• Medical history
• Family history of allergy or hearing disease
• Medications

II. Inspection - External Ear

• Observe size, shape and symmetry of both ears
• Auricles are normally level with each other, and upper point of attachment is in a straight line with the lateral canthus of the eye
• Inspect ear skin for color, lesions, rash and scaling
• Inspect area behind auricle for tophus (a deposit of sodium biurate in tissues near a joint, in the ear, or in bone in gout)

• Estimate size of external auditory meatus

IV. Otoscopic Examination

• Adult: Grasp auricle and pull UP and BACK to straighten external ear canal before inserting otoscope
• Child: Grasp auricle and pull DOWN and BACK
• Inspect ear canal for redness, swelling, discharge, crusting and foreign bodies
• Expect a small amount of moist, usually orange cerumen (ear wax). Cerumen is usually dry in Asians, Native Americans and the elderly
• Tympanic Membrane: 

1. Normal Finding: translucent, shiny, light gray, taut disk; free from tears or breaks
2. Test its mobility: Ask client to say "ah" or swallow. Intact membrane will vibrate slightly

V. Hearing Acuity: Four Tests

1. Gross hearing is tested by client's response to normal conversation
2. Whispered words or ticking watch test
3. Weber Test: Tuning fork of 512 cps is set to vibrate and placed perpendicularly on the midline vertex of the skull. Client asked to report in which ear sound is heard. If heard in one ear, suspect sensorineural loss in the other
4. Rinne Test: Compares sound conduction - air versus bone 

• Set tuning fork to vibrate
• Place on mastoid process
• Ask client whether the sound is heard and when it can no longer be heard. Note how long the sound can be heard
• When client states that sound  is gone, immediately move the tuning fork to about 2 cm from auditory canal
• Ask the client again whether there is sound and when it stops 
• Normal finding: latter sound should be heard twice as long as that of mastoid sound

VI. Geriatric Alterations

• Ear lobes may appear pendulous
• Presbycusis
