NUR612 Exam 7 (Latest Update) Questions and Verified
Answers| 100% Correct| Grade A
Meissner corpuscles - ANSWER-abundant in fingertips, lips, and other areas
proprioception - ANSWER-sense of body movement & position independent of vision; relayed to
cerebellum and cerebral cortex from the sensory afferents
upper motoneuron lesions - ANSWER-hyperactive reflexes, causes spasticity
lower motoneuron lesions - ANSWER-stretch reflex, which maintains muscle tone; leads to decreased
muscle tone, decreased resistance, weakness in distal limbs, hyporeflexia, fasiculations
Duchenne muscular dystrophy (DMD) - ANSWER-postural muscles of the hip and shoulders are first to
be affected
Myasthenia Gravis Disorder - ANSWER-loss of acetylcholine receptors
How to test for carpal tunnel syndrome? - ANSWER-Phalen's test
Parkinson's disease - ANSWER-disorder of the basal ganglia
confusion - ANSWER-disoriented to time, place, or person; memory difficulty, difficulty following
commands
delirium - ANSWER-inattentive, variably lethargic, agitated
obtundation - ANSWER-Responds verbally with a word; arousable with stimulation; responds
appropriately to painful stimuli; follows simple commands; appears very drowsy
, stupor - ANSWER-unresponsive except to vigorous and repeated stimuli; responds appropriately to
painful stimuli, lies quiet with minimal spontaneous movement, may have incomprehensible sounds
and/ or eye opening
coma - ANSWER-does not appropriately respond to stimuli, sleep-like state with eyes closed, does not
make verbal sounds
brain death - ANSWER-irreversible loss of function to the brain and brain stem
persistent vegetative state - ANSWER-prolonged coma, loss of all cognitive functions, unaware of self &
surroundings, reflex & vegetative functions remain (brainstem still functional, spinal reflexes remain);
condition must be present for at least a month to be diagnosed
epidural hematoma - ANSWER-develops between the bones of the skull and the dura
subdural hematoma - ANSWER-between the dura and the arachnoid (subdural) space
traumatic intracerebral hematoma - ANSWER-occur in any lobe of the brain but are most common in the
frontal or temporal lobes
dyssomnias - ANSWER-disorders of initiating and maintaining sleep and disorders of excessive sleepiness
parasomnias - ANSWER-undesirable phenomena that occur primarily during sleep; DND the sleep-wake
cycle
examples of parasomnias - ANSWER-nightmares, sleepwalking, sleep terrors, teeth grinding, bed wetting
CNS - ANSWER-brain and spinal cord, protected by the skull and vertebral column; "control center"
PNS - ANSWER-outside structures of the CNS; input-output system for relaying information to the CNS
and transmits output that controls effector organs; "robot- does what control center tells it to do"
Afferent neurons - ANSWER-sensory; located in the lateral columns
