NPTE Review Flashcards
(174 cards)
Neurapraxia
mildest form of acute nerve injury; axon/nerve fibers intact; rapid recovery usually in 4-6 weeks
Axonotmesis
more severe than neurapraxia; reversible damage to nerve fibers with possible Wallerian degeneration; recovery is spotty and surgery may be required for repair
Neurotmesis
most severe peripheral nerve injury; axon, myelin and connective tissue damaged; complete motor and sensory loss distal to injury; no spontaneous recovery
Ape Hand Deformity
atrophy of thenar musculature and first 2 lumbricals
Spondylitis
inflammation of the joints in the spine
Spondylosis
painful condition of the spine resulting from the degeneration of the intervertebral disks
Spondylolysis
crack or stress fracture develops through the pars interarticularis; most commonly in the fifth vertebra of the lumbar spine; sometimes occurs in the fourth lumbar vertebra (scotty dog fracture)
Spondylolisthesis
spondylolysis can weaken the vertebra so much that it is unable to maintain its proper position in the spine. This condition is called spondylolisthesis; fractured pars interarticularis separates, allowing the injured vertebra to shift or slip forward on the vertebra directly below it
Central Cord Syndrome (CCS)
incomplete SCI (compression/damage to central SC); MOI most often cervical hyperextension; motor loss greater in UE than LE and most severe distally in the UE; sensory loss below level of lesion limited (motor loss greater than sensory); damage can occur to spinothalamic, corticospinal and dorsal columns; most common incomplete SCI
Characteristics of Left CVA
right side weakness/paralysis; impaired processing; heightened frustration; aphasia; dysphagia; motor apraxia (ideational/ideomotor); right hemianopsia
Characteristics of Right CVA
left side weakness/paralysis; poor attention span; impaired awareness and judgement; spatial deficits; memory deficits; left inattention; emotional lability; impulsive behavior; left hemianopsia; (pusher syndrome maybe more common)
Chorea
jerky, involuntary movements; choreiform movements are repetitive and rapid, jerky, involuntary movement that appears to be well-coordinated
Athetoid
slow, involuntary, convoluted, writhing movements of the fingers, hands, toes, and feet and in some cases, arms, legs, neck and tongue
Relapse-remitting MS; RRMS
(85% of cases); characterized by clearly defined attacks of new or increasing neurologic symptoms. These attacks – also called relapses or exacerbations – are followed by periods of partial or complete recovery (remissions)
Secondary-progressive MS; SPMS
SPMS follows an initial relapsing-remitting course. Most people who are diagnosed with RRMS will eventually transition to a secondary progressive course in which there is a progressive worsening of neurologic function (accumulation of disability) over time. SPMS can be further characterized at different points in time as either active (with relapses and/or evidence of new MRI activity) or not active, as well as with progression (evidence of disease worsening on an objective measure of change over time, with or without relapses) or without progression.
Primary-progressive MS; PPMS
characterized by worsening neurologic function (accumulation of disability) from the onset of symptoms, without early relapses or remissions
Progressive-relapsing MS; PRMS
rare form of MS (5%), PRMS is characterized by a steadily worsening disease state from the beginning, with acute relapses but no remissions, with or without recovery
Anterior Cord Syndrome
incomplete SCI in which anterior 2/3 of SC is damaged; compression/damage to anterior spinal artery (most often via cervical flexion or fracture/dislocation); complete loss of motor function and loss of pain and temperature sensation bilaterally below the level of lesion due to damage to corticospinal and spinothalamic tracts; intact vibration and proprioception; worst prognosis of SC syndromes
S1 (heart sound)
closing of the mitral and tricuspid valves; onset of ventricular systole
S2 (heart sound)
closing of the aortic and pulmonary valves; onset of ventricular diastole
S3 (heart sound)
Ventricular gallop; may occur in healthy children and young adults; indicates a loss of ventricular compliance in the presence of heart disease or heart failure
S4 (heart sound)
Atrial gallop; associated with atrial contraction and an increased resistance to ventricular filling; common in pts. with HTN, history of MI, or coronary bypass surgery
Digitalis (digoxin)
Rx given to increase force of myocontractility, often prescribed for heart failure; increased cardiac output and decreased preload, cardiac workload, and myocardial oxygen demand; prolongs PR interval on ECG, may shorten QT interval or produce sagging in ST segment
Atrial flutter
abnormal heart rhythm characterized by rapid atrial tachycardia (250-350 bpm); fast but regular rhythm producing sawtooth P waves on ECG
