Be familiar with the terms widened pulse pressure, pulsus alternans, pulsus paradoxus (paradoxical pulse) (119). Wide pulse pressure o Large difference between systolic and diastolic blood pressures o Indicated decreased arterial compliance, arterial injury Pulsus alternans o alternating pulse amplitude, usually associated with left-sided heart failure; o best felt in the radial or femoral arteries o may be accentuated by upright positioning, usually accompanied by S3 heart sound Pulsus paradoxus o Pulse varies in amplitude with respirations o Typical w/ cardiac tamponade, constrictive pericarditis, obstructive lung disease 3. Be familiar with the murmurs aortic stenosis, aortic regurgitation, mitral stenosis, and mitral regurgitation. Understand the special maneuvers to identify systolic murmurs, i.e. Valsalva maneuver or squatting/standing (291-94). Systolic Aortic Stenosis Mechanism Immobile valve impairs blood flow across it, causing turbulence Murmur Mid-systolic Mitral regurgitation Diastolic Aortic Regurgitation Mitral Stenosis Valsalva Maneuver Standing (Strain) Squatting (Release) Failure of MV to close fully Pan/holo-systolic Mechanism Murmur Failure of AV to close fully Early decrescendo Failure of valve to open sufficiently Rumbling in mid or late diastole Cardiovascular Effect Decreased LV volume from decreased venous return to heart Decreased vascular tone (decreased arterial pressure and peripheral vascular resistance) Increased left ventricular volume Increased vascular tone Effect on Systolic Sounds and Murmurs Mitral Valve Hypertrophic Aortic Stenosis Prolapse Cardiomyopathy Increase prolapse Increased outflow Decreased blood volume of valve click obstruction ejected into aorta moves earlier in increased intensity decreased intensity of systolic and of murmur murmur murmur lengthens and gains intensity Decreased prolapse delay of click, murmur shortens and loses intensity Decreased outflow obstruction decreased intensity of murmur Increased blood volume ejected into aorta increased intensity of murmur The Breasts (Ch 9): 1. Be able to perform the techniques of examining the breasts. INSPECTION o Patient should be sitting; disrobed to waist. Inspect breast (and nipples) for skin changes, symmetry, contours, and retraction in 4 views: arms at side, arms over head, arms pressed against hips, and leaning forward. Teen girls’ breasts assessed according to Tanner stages (779). o Arms at Sides Skin appearance Color – redness from infection or inflammatory carcinoma Thickening and prominent pores suggest breast cancer Size and symmetry (differences are normal) Contour Look for changes such as masses, dimpling, flattening Flattening of normally convex breast suggests cancer Characteristics of the nipples, including size, shape, direction they point, rashes, ulcerations, discharges Asymmetry of directions suggests cancer; rash or ulceration in Paget’s disease o Arms over Head; Hands Pressed Against Hops; Leaning Forward Dimpling or retraction suggestive of cancer or occasionally associated with benign lesions such as posttraumatic fat necrosis or mammary duct ectasia PALPATION o Best performed when breast tissue flattened – patient supine. o Palpate rectangular area extending from clavicle to infra-mammary fold or bra line and from midsternal line to posterior axillary line and into axilla for the tail of the breast. o Thorough exam takes 3 minutes per breast. o Use fingerpads of 2nd, 3rd, 4th finger, keeping fingers slightly flexed. Be systematic. Circular or wedge pattern can be used, but vertical strip pattern currently best validated technique for detecting breast masses. o Palpate in small, concentric circles at each point, applying light, medium, deep pressure, pressing more firmly to reach deeper tissues of larger breasts. Exam should cover entire breast, including periphery, tail, axilla. Do not mistake normal rib for hard breast mass. o To examine lateral portion of breast, patient should roll on opposite hip, placing hand on forehead, keeping shoulders pressed against bed or exam table. This flattens breast tissue. Begin palpation in axilla, moving in straight line down to bra line, then move fingers medially and palpate in vertical strip up the chest to clavicle. Continue in vertical overlapping strips until nipple reached, then reposition patient to flatten medial portion of the breast. Nodules in tail of breast sometimes mistaken for axillary lymph nodes and vice versa. o To examine medial portion of breast, ask patient to lie with shoulders flat against bed, placing hand at neck and lifting elbow until it is even with shoulder. Palpate in straight line down from nipple to bra line, then back to clavicle, continuing in vertical overlapping xtrips to midsternum. o Examine breast tissue for Consistency – varies widely. Physiologic nodularity sometimes present, increasing before menses. There may be firm transverse ridge of compressed tissue along lower margin of breast, especially large ones. This is normal inframammary ridge, not a tumor. Tender cords suggest mammary duct ectasia, benign but sometimes painful dilation of ducts with surrounding inflammation and sometimes masses. Tenderness – can be premenstrual Nodules – qualitatively different from rest of breast; called a dominant mass, reflecting pathology requiring mammogram, aspiration or biopsy. Characteristics: Location (by quadrant or clock, cm from nipple), size in cm Shape – round or cystic, disclike, or irregular in contour Consistency – soft, firm, hard Delimitation – well circumscribed or not Mobility in relation to skin, pectoral fascia, chest wall. Cysts, inflamed areas, some cancers may be tender Try to move mass while patient relaxes arm and then while hand pressed against hip. Mobile mass that becomes fixed when arm relaxes is attached to ribs and intercostals muscles; if fixed when hand pressed against hip, it’s attached to pectoral fascia. NIPPLES o Palpate each nipple, noting elasticity o Thickening or loss of elasticity – possible cancer. MALE BREAST o Inspect nipple and areola for nodules, swelling or ulceration. o Palpate areola and breast tissue for nodules. o If breast enlarged, distinguish between soft fatty enlargement of obesity and firm disc of glandular enlargement – gynecomastia, attributed to imbalance of estrogens and androgens and sometimes drug-related. o Hard, irregular, eccentric, or ulcerating nodule is not gynecomastia, but suggests breast cancer. AXILLAE: Sitting position preferable to patient lying down for examination. o INSPECTION Rash – deodorant-induced or other Infection – sweat gland infection (hidradenitis suppurativa) Unusual pigmentation – deeply pigmented, velvety axillary skin suggests acanthosis nigricans, a form of which is associated with internal malignancy o PALPATION To examine left axilla, ask patient to relax with left arm down. Help by supporting left wrist or hand with your left hand. Cup together fingers of your right hand and reach as high as possible toward apex of axilla. Warn patient that this may feel uncomfortable. Your fingers should be behind pec muscles, pointing toward midclavicle. Press fingers in toward chest wall and slide downward, trying to feel central nodes against chest wall (most palpable of axillary nodes). One or more soft small (< 1 cm) nontender nodes frequently palpable. Enlarged axillary nodes from infection of hand or arm, recent immunizations or skin tests in arm, or part of generalized lymphadenopathy. Check epitrochlear and other groups of lymph nodes. Nodes larger than 1 cm suggest malignancy. Use left hand to examine right axilla. If central nodes feel large, hard, tender, or if there is suspicious lesion in drainage areas for axillary nodes, feel for other groups of axillary lymph nodes – pectoral, lateral, subscapular nodes. Also feel for infra and supraclavicular nodes. Special Techniques o Assess for spontaneous nipple discharge, especially if there is prior hx. Try to determine origin by compressing areola with index finger placed in radial positions around nipple. Watch for discharge from duct openings on nipple surface. Note color, consistency, quantity, location. Milky discharge unrelated to prior pregnancy and lactation called nonpuerperal galactorrhea – leading causes are hormonal and pharmacologic. o Take special care with exam of mastectomy patient (likewise women with breast augmentation or reconstruction), inspecting mastectomy scar and axilla for masses, nodularity. Note changes in color, signs of inflammation. Lymphedema may be present in axilla or upper arm from impaired lymph drainage after surgery. Palpate gently along scar using 2 or 3 fingers in circular motion, paying special attention to upper outer quadrant and axilla. 2. Be comfortable with the three most common kinds of breast masses, fibroadenoma, cysts, and cancer. (357) Fibroadenoma Cysts Cancer 15-25, usually puberty 30-50, regress after 30-90, most common Usual Age And young menopause except over 50 (middle age, adulthood, to 55 With estrogen tx ellderly) Usually single; may Usually single; may Number Single or multi coexist with other be multi nodules Round, disc-like or Shape Round Irregular or stellate lobular May be soft, usually Solid to firm, usually Consistency Firm or hard firm elastic Delineation Well delineated Well delineated Not clearly May be fixed to skin Mobility Very mobile Mobile or underlying tissues Tenderness Usually non-tender Often tender Usually non-tender Retraction Signs absent Absent May be present 3. Recognize the visible signs of breast cancer, i.e. skin dimpling, nipple retraction, peau d’orange. (356) a. Retraction signs o Mechanism – breast cancer causes fibrosis (scar tissue) as it advances. Shortening of fibrotic tissue causes retraction signs but other causes include fat necrosis, mammary duct ectasia. b. Skin dimpling o Look for this sign with patient’s arm at rest, during special positioning and on moving or compressing breast. Abnormal contours o Look for variation in normal convexity, comparing one side of each breast with the other. Special positioning may be useful. d. Nipple retraction and deviation o Flattened or pulled inward or may be broadened and feel thickened. o When involvement is radially asymmetric, nipple may deviate, i.e., point in different direction from its normal counterpart, typically toward underlying cancer e. Edema of the skin (Peau d’orange) o Produced by lymphatic blockade; appears as thickened skin with enlarged pores o Often seen 1st in lower portion of breast or areola f. Paget’s Disease of the nipple o Uncommon form of breast cancer that usually starts as scaly, eczema-like lesion. Skin may also weep, crust, erode; breast mass may be present o Suspect Paget’s in any persisting dermatitis of the nipple and areola c. The Abdomen (Ch 10): 1.

Pain Chronic Arterial Insufficiency Intermittent claudication, progressing to pain at rest Pulses Decreased or absent Color Pale, esp. on elevation; dusky red on dependency Temperature Cool Absent or mild; may develop as the patient tries to relieve rest pain by lowering the leg Edema Skin Changes Trophic changes: thin, shiny, atrophic skin; loss of hair over the foot and toes; nails thickened and rigid Ulceration If present, involves toes or points of trauma on feet Gangrene May develop Chronic venous insufficiency None to an aching pain on dependency Normal, though may be difficult to feel through edema Normal, or cyanotic on dependency; petechiae and then brown pigmentation appear w/ chronicity Normal Present; often marked Often brown pigmentation around the ankle, stasis dermatitis, and possible thickening of the skin and narrowing of the leg as scarring develops If present, develops at sides of ankle, especially medially Does not develop 2. Know the areas of lymph nodes that should be examined and what areas they drain (476-477). Cervical nodes (170) Axillary nodes (339) o Central nodes post frequently palpable o Receive drainage from pectoral, subscapular, and lateral nodes o Drains all areas of the arm except for those drained by epitrochlear nodes Epitrochlear nodes o Medial surface of the arm 3cm above the elbow o Drains ulnar surface of the forearm and hand, little and ring fingers, adjacent surface of the middle finger Superficial Inguinal Nodes o Horizontal group High in the anterior thigh below the inguinal ligament Drains superficial portions of lower abdomen and buttock, external genitalia, anal canal, and lower vagina o Vertical group Cluster near upper part of saphenous vein Drains area drained by the great saphenous vein 3. Be able to examine for edema and the different characteristics of pitting edema, chronic venous insufficiency, and lymphedema (496). Pitting Edema Chronic Venous Insufficiency Lymphadema Nature of Edema Soft, pits on pressure Soft, pits on pressure, later may become brawny (hard) Soft in early stages, then becomes indurated, hard, nonpitting Skin Thickening Absent Ulceration Pigmentation Edema of Foot Bilaterality Absent Absent Present Always Inc interstitial fluid from: legs dependent from prolonged standing/sitting inc hydrostatic pressure In veins, capillaries, CHF decreased cardiac output low albumin, decreased intra-vascular colloid oncotic pressure; drugs Examples/ Mechanisms May be present, especially near ankle Common Common Often present Occasionally Chronic obstruction or valvular incompetence of the deep veins Becomes marked Rare Absent Present, including toes Often Lymph channels obstructed by tumor, fibrosis, inflammation; also from axillary node dissection, radiation The Musculoskeletal System (Ch 15): UCSD: http://medicine.ucsd.edu/clinicalmed/Joints.html 1. Be able to describe range of motion and maneuvers: flexion, extension, abduction, adduction, rotation (516). 2. Be able to describe supination (turn up the palms), pronation (turn down palms) of hand and inversion and eversion of the foot/ankle (554 for figures). 3. Know the classic swellings and deformities of the hands seen in osteoarthritis, rheumatoid arthritis, and Dupuytren’s contracture (Table 15-6, p567-569). Osteoarthritis (degenerative joint disease) o Nodules on dorsolateral aspects of DIP joints (Heberden’s nodes) due to bony overgrowth. o Usually hard and painless, affecting middle-aged or elderly, often but not always assoc. w/ arthritic changes in other joints. Sometimes flexion and deviation deformities. o Similar nodules on PIP joints (Bouchard’s nodes) less common. MCP joints spared. Rheumatoid Arthritis o Acute – tender, painful, stiff joints. Symmetric involvement on both sides of body typical. PIP, MCP, wrist joints frequently affected; DIP joints rarely so. Often patients have fusiform or spindle-shaped swelling of PIP joints. o Chronic – chronic swelling and thickening of MCP and PIP joints. ROM limited and fingers deviate ulnarly. Interosseous muscles atrophy. Fingers may show “swan neck” deformities (hyperextension of PIP joints with fixed flexion of DIP joints). Less common is boutonniere deformity (persistent flexion of PIP with hyperextension of DIP). o Rheumatoid nodules may accompany either acute or chronic stage. Dupuytren’s contracture – 1st sign is thickened plaque overlying flexor tendon of ring finger and possibly little finger at distal palmar crease. Subsequently skin in this area puckers and thickened fibrotic cord develops between palm and finger. Flexion contracture of fingers may gradually ensue. 4. Be able to describe the techniques for examining the knee: Anterior Drawer Sign, Lachman Test, McMurray Test (550-551) ACL o Anterior Drawer Sign – with patient supine, hips flexed and knees flexed to 90 degrees and feet flat on table, cup your hands around the knee with the thumbs on medial and lateral joint line and fingers on medial and lateral insertions of the hamstrings. Draw tibia forward and observe if it slides forward (like a drawer) from under femur. Compare the degree of forward movement with that of opposite knee. Few degrees of forward movement normal if equally present on opposite side. Forward jerk showing contours of upper tibia is positive anterior drawer sign suggesting a tear of ACL. o Lachman Test – place knee in 15 degrees of flexion and external rotation. Grasp distal femur with one hand and upper tibia with the other. With thumb of tibial hand on joint line, simultaneously move tibia forward and femur back. Estimate degree of forward excursion. Significant forward excursion = ACL tear. Medial meniscus and lateral meniscus o McMurray Test – if click felt or heard at joint line during flexion and extension of knee, or if tenderness is noted along joint line, further assess meniscus for posterior tear. o With patient supine, grasp heel and flex the knee. Cup your other hand over the knee joint with fingers and thumb along the medial and lateral joint line. From the heel, rotate the lower leg internally and externally. Then push on the lateral side to apply a valgus stress on the medial side of the joint. At the same time, rotate leg externally and slowly extend it. A click or pop along medial joint with valgus stress, external rotation, and leg extension suggests probable tear of posterior medial meniscus. 5. Know Phalen’s test, Tinel’s sign, and what a positive straight leg raise means (555-556). Phalen’s test o Hold patient’s wrists in acute flexion for 60s; alternatively, ask patient to press backs of both hands together to form right angles these maneuvers compress median nerve. o If numbness and tingling develop over the distribution of the median nerve (e.g., the palmar surface of the thumb, and the index, middle, and part of the ring fingers), the sign is positive, suggesting carpal tunnel syndrome. Tinel’s sign o Percuss lightly over course of median nerve in carpal tunnel at palmar-forearm crease of wrist (see Bates figure p.555) o Tingling or electric sensations in distribution of median nerve constitutes positive test for carpal tunnel syndrome Positive straight leg raise o For low back pain with radiation into the leg. o Patient should be supine. Raise patient’s relaxed and straightened leg until pain occurs. Then dorsiflex foot. Record degree of elevation at which pain occurs, quality, distribution of pain, effects of dorsiflexion o Tightness and mild discomfort of hamstrings are common with this maneuver and do not indicate radicular pain (L5 or S1) o Sharp pain radiating from back down the leg (increased on dorsiflexion of foot) suggests tension on or compression of nerve roots, often caused by herniated lumbar disc. Increased pain in affected leg when opposite leg raised strongly confirms radicular pain and constitutes positive crossed straight leg-raising sign The Nervous System (Ch 17): 1. Know the segmental levels of the deep tendon reflexes (634-637). Ankle reflex – S1 (primarily) Knee reflex – L2,3,4 Supinator – C5,6 Biceps reflex – C5,6 Triceps reflex – C6,7 2. Be familiar with the zero to five scale of muscle strength (619). 0 – No muscular contraction detected 1 – A barley detectable flicker or trace of contraction 2 – Active movement of the body part with gravity eliminated 3 – Active movement against gravity 4 – Active movement against gravity and some resistance 5 – Active movement against full resistance without evident fatigue (normal muscle strength) 3. Be able to perform the techniques for examining the cranial nerves (611-616). CN I o nasal patency (loss of smell: nasal disease, head trauma, smoking, aging, cocaine) CN II o Visual Acuity (optic atrophy, papilledema) o Confrontation (extinction lesion in parietal cortex) o Pupillary reactions to light CN III, IV, VI o Extraocular movements in 6 cardinal directions o Nystagmus Ptosis CN V o Motor i. Palpate masseter muscles, with patient’s teeth clenched o Sensory i. Pain, temperature, light touch ii. Corneal Reflex (observe blinking in reaction to this stimulus) CN VII (Note weakness of asymmetry in the following) o Raise eyebrows o Smile/Frown (unilateral facial paralysis mouth droops) o Puff out both cheeks o Show both upper and lower teeth o Close eyes tightly so that you cannot open them to test muscle strength CN VIII o Hearing lateralization and air/bone conduction CN IX, X o Voice hoarseness? Vocal cord paralysis; nasal voice? Paralysis of the palate o Movements of soft palate and pharynx palate fails to rise with bilateral lesion of X; unilateral rise of palate and uvula deviation toward normal side with unilateral lesion o Gag reflex unilateral absence? Lesion of IX or X CN XI o Observe for atrophy or fasciculations (fine, flickering, irregular movements in small groups of muscle fibers) indicative of peripheral nerve disorder o Supine patient w/ bilateral weakness of SCM has difficulty raising head off pillow CN XII o Observe for atrophy or fasciculations (fine, flickering, irregular movements in small groups of muscle fibers) indicative of peripheral nerve disorder (ALS, polio) o o Disorders of speech Cortical Lesions Tongue deviation toward contralateral side 4. Be able to perform the techniques: Romberg sign, pronator drift (629). Romberg Sign o Patient should stand with feet together and eyes open, then close both eyes for 20-30s without support (note ability to maintain upright posture, minimal swaying is normal) o Positive Rhomberg sign – patient can maintain balance with eyes open, but have a loss of balance with eyes closed o Cerebellar ataxia – patient has difficulty standing with feet together whether the eyes are open or closed Pronator Drift o Patient should stand for 20-30s with both arms straight forward, palms up, with eyes closed o Pronation of one forearm suggests a contralateral lesion of the corticospinal tract; may also be accompanies by downward drift of the arm with flexion of fingers and elbow Mental Status (Ch 16): 1. Be able to identify the various levels of consciousness: alertness, lethargy, obtundation, stupor, coma (Table, p.634) Alertness o address patient in normal tone of voice. Alert patient opens eyes, looks at you and responds appropriately. Lethargy o speak to patient in loud voice. Lethargic patient appears drowsy but opens eyes, looks at you, responds to questions, then falls asleep. Obtundation o shake patient as if to awakening a sleeper. Obtunded patient opens eyes, looks at you, but responds slowly and is somewhat confused. Alertness and interest in environment decreased. Stupor o stuporous patient arouses from sleep only after painful stimuli. Slow or absent verbal responses. Patient lapses into unresponsive state when stimuli removed. Minimal awareness of self or environment. Coma o comatose patient unarousable, eyes closed. No evident response to inner need or external stimuli. 2. Know how to evaluate speech and language and how to test for aphasia (p580 Table 16-2, p.591) Note quantity, rate, loudness, articulation, fluency. 2 kinds of aphasia – o Wernicke’s (fluent, receptive; posterior superior temporal lobe) – all domains impaired. o Broca’s (non-fluent, expressive; posterior influent frontal lobe) – word and reading comprehension fair to good; other domains impaired (including patient recognizing objects but unable to name them). Testing for Aphasia o Word comprehension – ask patient to follow 1-stage (“point to nose”) then 2-stage command (“point to mouth and knee”). o Repetition – ask patient to repeat phrase of monosyllabic words (“no ifs ands or buts”) o Naming – ask patient to name parts of a watch. Reading comprehension – ask patient to read paragraph aloud Writing – ask patient to write a sentence Consider deficiencies in vision, hearing, intelligence, and education on performance of tests. A person who can write a correct sentence does not have aphasia. 3. Recognize abnormalities in thought process, i.e. flight of ideas, neologisms, confabulation, etc. and thought content, i.e. phobias, delusions, obsessions (582) Thought Process o Circumstantiality – indirection and delay in reaching point b/c of unnecessary detail, although components of description meaningfully connected (obsessional people but also applies to people without mental disorder). o Derailment (loosening of associations) – person shifts from one subject to others unrelated or obliquely related without realizing subjects not meaningfully related; ideas slip off track between clauses, not within them (in schizophrenics, manics, other psychotics). o Flight of ideas – almost continuous flow of rapid speech with changes of topic; changes based on understandable associations, plays on words, distracting stimuli, but ideas do not progress to sensible conversation (manics) o Neologisms – invented or distorted words or words with new or highly idiosyncratic meanings (schizos, psychotics, aphasics) o Incoherence – largely incomprehensible speech b/c of illogic, lack of meaningful connections, etc; shift in meaning within clauses; flight of ideas may produce incoherence (typically schizos) o Blocking – sudden interruption of speech in midsentence or before completion of idea; attributed to loss of train of thought (schizos but also in normal people) o Confabulation – fabrication of facts or events in response to questions, to fill in gaps in impaired memory (amnesiacs) o Perseveration – persistent repetition of words words or ideas ideas (schizos, other psychos) o Echolalia – repeating other people’s words or phrases (manics and schizos) o Clanging – speech wherein a person chooses a word based on sound rather than meaning, as in rhyming or punning. “Look at my eyes and nose, wise eyes rosy nose…the ayes have it!” (schizos, manics) Thought Content o Compulsions, obsessions, phobias, anxieties often associated with neuroses (anxiety disorders) o Delusions and feelings of unreality or depersonalization more often associated with psychotic disorders such as schizophrenia. Delusions may also occur in delirium, severe mood disorders, dementia. 4. Know how to administer tests of memory and attention (584-585). Attention: serial 7’s; spell W-O-R-L-D backwards Remote memory: inquire about birthdays, anniversaries, names of schools attended, etc Recent memory: the day’s weather, medications taken, but NOT what had for breakfast (unless can be verified) New learning ability: give the patient 3 or 4 words to repeat – “table, flower, green, hamburger.” ask patient to repeat the words so that you know information has been heard and registered. Proceed to other parts of exam. After 3-5 minutes ask patient to repeat words.
