EXAM #3 Study Guide:2022 Rectal/prostate exam position - knee-chest; lithotomy; left lateral with hips and knees flexed; or standing with the hips flexed leaning on exam table Rectal/prostate exam ... position males - left lateral with hips and knees flexed or standing with the thips flexed leaning on exam table Rectal/prostate exam position women - most often performed as part of the rectovaginal examination in the lithotomy position Rectal/prostate exam procedure - Lubricate index finger of gloved hand, press the pad against the anal opening, ask patient to bear down then slip tip into anal canal, ask to tighten sphincter noting tone, palpate for masses, nodules, irregularities, palpate lateral/posterior/anterior rectal walls, prostate (on anterior wall) Normal prostate exam - should feel like a pencil eraser— firm, smooth, and slightlymovable/nontender. Diameter of about 4 cm, with less than 1 cm protrusion into the rectum. Lobes should feel symmetric, seminal vesicles should not be palpable. Abnormal prostate exam - greater than 1 cm protrusion into rectum means enlargement, obliterated median sulcus means hypertrophied or neoplastic nodes, rubbery/boggy consistency means benign hypertrophy, stony/hard nodularity may mean carcinoma, prostatic calculi, chronic fibrosis, tender/fluctuant softness means prostatic abscess, palpable seminal vesicles means inflammation Extremely tight sphincter - scarring, spasticity from fissure or lesion, inflammation, anxiety Lax sphincter - neuro deficit or sexual abuse Rectal pain - anal fistula, anal fissure, perirectal abscess, thrombosed hemorrhoids Bidigital palpation - helpful for identifying perianal abscess, press thumb against anus while palpating with index finger Rectal prolapse findings - rectum starts to drop down, rectum partially protrudes, rectum fully protrudes; characterized by feeling of a bulge, bleeding, or pain Rectal prolapse causes - constipation, diarrhea, gynecologic surgery, pelvic neuropathies, or severe coughing/straining, age, nerve damage Hemorrhoid - varicose veins in lower rectum or anus, may be internal or external External hemorrhoids - may cause itching, bleeding, discomfort; invisible at rest, protrude on standing, straining; thrombosed are blue, shiny masses at anusInternal hemorrhoids - may have no symptoms, are soft swellings not palpable on rectal exam not visible unless prolapsed, dx w/ proctoscopy Rectal bleeding causes - anal fissures, anaphylactoid purpura, aspirin use, bleeding & coagulation disorders, colitis, dysentery, esophageal varices, familial telangiectasia, foreign body trauma, hemorrhoids, hiatal hernia, hookworm, intussusception, iron poisoning, Meckel diverticulum, neoplasms, oral steroids, peptic ulcers, polyps, regional enteritis, strangulated hernia, swallowed blood, thrombocytopenia, volvulus MS exam sequence - observe gait/posture as patient enters room, inspect (posture, deformities, symmetry, alignment, hypertrophy), palpate (bones, joints, tendons, muscles), evaluate ROM and muscle tone, muscle strength (hands, elbows, shoulders, TMJ, cervical/thoracic/lumbar spine ROM, hips, legs and knees, feet and ankles Limb measurement - asymmetry in limb size, normal is no more than 1 cm discrepancy in length and circumference; athletes w/ dominant arm may have greater discrepancy in circumferences Leg length - measured from the anterior superior iliac spine to the medial malleolus of the ankle, crossing the knee on the medial side Arm length - measured from the acromion process through the olecranon process to the distal ulnar prominence. Neer test identifies - shoulder rotator cuff impingement or tear Hawkins test identifies - shoulder rotator cuff impingement or tear Katz hand diagram - median nerve integrity Thumb abduction test - median nerve integrity; isolates strength of the abductor pollicis brevis muscle, innervated only by median nerve. Place the hand palm up and raise the thumb perpendicular to it. Apply downward pressure on the thumb to test muscle strength; full resistance to pressure is expected; weakness associated CTS Tinel sign - median nerve integrity; strike patient's wrist w/ index or middle finger where the median nerve passes under the flexor retinaculum and volar carpal ligament; tingling sensation radiating from the wrist to the hand in the distribution of the median nerve is positive, suggests CTS Phalen test - median nerve integrity; hold both wrists in a fully palmar-flexed position with the dorsal surfaces pressed together for 1 minute, numbness/tingling = CTS Reverse Phalen tests - hold hands together as if praying, press for 1 minuteLess likely CTS - Tinel and Phalen tests are ________ than Katz and Thumb test Straight leg raising - L4, L5, S1 nerve root irritation Femoral stretch test - L1, L2, L3, L4 nerve root irritation Ballottement and Bulge sign - effusion in the knee Ballottement - extend knee, push down on suprapatellar pouch with the web/thumb and forefinger of one hand, push the patella quickly downward against the femur with other hand; tapping or clicking will be sensed when the patella is pushed against the femur if effusion present. Release pressure and keep your finger lightly touching patella, patella will float out as if a fluid wave were pushing it if effusion present Bulge sign - knee extended, milk the medial aspect of the knee upward two or three times, and then milk the lateral side of the patella. Observe for a bulge of returning fluid to the hollow area medial to the patella McMurray test - supine, flex one knee, put thumb and fingers on either side of the joint space. Hold the heel with your other hand, fully flexing the knee, and rotate the foot and knee outward (valgus stress) to a lateral position. Extend and then flex the patient's knee. Any palpable or audible click, pain, or limited extension of the knee is a positive sign of a torn medial meniscus. Repeat while rotating the foot and knee inward (varus stress) A palpable or audible click, pain, or lack of extension is a positive sign of a torn lateral meniscus. Varus stress - McMurray, foot rotated in, sign of torn lateral meniscus Valgus stress - McMurray, foot rotated out, sign of torn medial meniscus Varus - abduction Valgus - adduction Anterior and posterior drawer test - ACL/PCL instability; supine, knee flexed 45 to 90 degrees, foot flat on the table. Place both hands on the lower leg with the thumbs on the ridge of the anterior tibia just distal to the tibial tuberosity. Draw the tibia forward, forcing the tibia to slide forward of the femur. Then push the tibia backward. Knee movement over 5 mm in either direction is an unexpected finding. Varus-valgus stress test - medial or lateral collateral ligament instability in knee Varus-valgus stress test how to - for lateral and medial collateral ligaments; pt supine, knee extended, stabilize femur with one hand, hold the ankle with other. Apply varus force against the ankle (toward the midline) and internal rotation. Excessive laxity is felt as joint opening = injury to the lateral collateral ligament. Repeat w/ valgus force (awayfrom midline/external rotation), laxity = injury to medial collateral ligament. Repeat w/ knee flexed to 30 degrees, excessive movement not expected. Lachman test - anterior cruciate ligament integrity; pt. supine, flex knee 10-15 degrees, heel on table. One hand above knee to stabilize femur, other around proximal tibia, pull tibia anteriorly while pt. relaxes hamstring; Increased laxity over 5 mm compared w/ uninjured side = ligament injury Thomas test - pt supine; fully extend one leg flat, other leg knee to the chest. Observe if pt can keep extended leg flat, if It lifts, = flexion contracture of hip of extended leg Trendelenburg sign - have patient stand and balance on one foot and then the other, note any asymmetry or change in the level of the iliac crests from behind; if iliac crest drops on the side of the lifted leg, this indicates the weak hip abductor muscles on weight-bearing side MS age-related changes - may need slower exam, increased dorsal kyphosis w/ flexion of the hips and knees; head may tilt backward d/t thoracic curvature, extremities may appear long d/t vertebral collapse, feet more widely spaced, arms away from the body to aid balancing; reduction in total muscle mass related to atrophy, Osteoarthritis risk factors - obesity female, family hx of osteoarthritis, hypermobility syndromes, age 40+, injury, high sports activities, peripheral neuropathy, job requiring joint overuse Osteoarthritis findings - pain (hands, feet, hips, knees, cervical/lumbar spine), onset after 40, nearly 100% of people over 75, develops slowly, brief morning stiffness, pain with use/relief with rest, enlarged joints d/t osteophytes, crepitus, limited, painful ROM, non-inflammatory effusion, no heat, tender joints, heberden nodes, bouchard nodes Rheumatoid findings - joint pain/stiffness, gradual onset, pain at rest, worse in morning and after inactivity, constitutional sx (severe fatigue, myalgias, weight loss, low-grade fever); involves hands, wrists, feet, ankles, hips, knees, cervical spine; synovitis w/ soft tissue swelling and effusions present on exam, nodes and deformities may develop, sometimes hot/red joint Carpal tunnel assessment - Katz hand diagram, thumb abduction test, Tinel sign, Phalen (all assess median nerve integrity) Carpal tunnel findings - numbness, burning, tingling or pain, often at night; associated with rheumatoid arthritis, gout, acromegaly, hypothyroidism, and pregnancy Plantar fasciitis special tests - Tinel test along distal tibial nerve to r/o tarsal tunnel syndrome, Calcaneus squeeze test to r/o calcaneal stress fracture.Plantar fasciitis findings - aching heel pain, worse w/ first step; better w/ activity, worse if prolonged Gout findings - Sudden onset, hot, swollen joint (usually proximal phalanx of great toe, also wrists, hands, knees) d/t monosodium urate crystals, exquisite pain; limited ROM, skin may be shiny red/purple, uric acid crystal tophi under skin when chronic; men over 40, postmenopausal women Meningitis assessment - Nuchal rigidity (pain/rigidity when neck flexed in supine position, possible swollen glands), Brudzinski's sign (involuntary hip flexion when neck flexed), Kernig sign (flex knee at hip when supine, attempt to straighten leg, positive if pain in lower back and resistance to straightening) Jolt accentuation of headache - if fever/headache when meningitis suspected, pt rotate head horizontally 2-3 times per second, increased headache over baseline positive Meningitis findings - fever, stiff neck, and AMS; also headache, rash, nausea, vomiting, chills, and myalgia.

Kids may be observed playing. Barlow-Ortolani maneuver - IDs hip dislocation or subluxation, all exams to age 1. Using little force, test one hip at a time, stabilizing the pelvis with the other hand. By 3 months of age, muscles and ligaments tighten, and limited abduction of the hips becomes the most reliable sign of hip subluxation or dislocation Barlow - infant supine, flex the hip and knee to 90 degrees; grasp the leg , adduct thigh and gently apply downward pressure on the femur in an attempt to disengage thefemoral head from the acetabulum. A positive sign is when a clunk or sensation is felt as femoral head exits the acetabulum posteriorly. Ortolani maneuver - slowly abduct thigh while maintaining axial pressure. With the fingertips on the greater trochanter, exert a lever movement in the opposite direction so that your fingertips press the head of the femur back toward the acetabulum center. If the head of the femur slips back into the acetabulum with a palpable clunk when pressure is exerted, suspect hip subluxation or dislocation. High-pitched clicks are common/expected. Allis sign - detects hip dislocation or shortened femur. Supine infant, flex both knees, keeping the feet flat on the table close to the buttocks and the femurs aligned with each other. Observe knee height, if one higher, sign is positive.

manage sensory signals necessary for complex discrimination tasks. Posterior (dorsal) column spinal tract - (fasciculus gracilis and fasciculus cuneatus) - fine touch, two-point discrimination, and proprioception. Spinothalamic - light and crude touch, pressure, temperature, and pain. Descending spinal tracts - (corticospinal, reticulospinal, vestibulospinal) convey impulses from brain to muscle groups by inhibiting or exciting spinal activity. Also help control muscle tone, posture, and precise motor movements. Corticospinal (pyramidal) tract - skilled, delicate, and purposeful movements. Vestibulospinal tract - causes the extensor muscles of the body to suddenly contract when an individual starts to fall. Corticobulbar tract arising from the brainstem - innervates motor functions of the cranial nerves. Upper motor neurons - nerve cell bodies for the motor pathways that all begin and end within the central nervous system. Include descending pathways from brain to spinal cord. Influence, direct, and modify spinal reflex arcs and circuits. Upper motor neurons - affect movement only through the lower motor neurons. Lower motor neurons, cranial and spinal motor neurons - originate in the anterior horn of the spinal cord and extend into the peripheral nervous system; Transmit neural signals directly to the muscles to permit movement.
