NURS 231: PATHOPHYSIOLOGY MODULE 6 EXAM QUESTIONS
AND ANSWERS UPDATED RATED A+
Cognition
The ability to take in sensory input, evaluate that input, store it,
and retrieve it for later use, i.e., learn to recognize familiar
objects and people, recall past events and experiences, and be
able to assess situations and respond accordingly
Dementia
Impaired cognitive functioning that interferes with a person's
ability to navigate daily tasks and social interactions
Features of alzheimer's
(1) the presence of neuritic (senile) plaques,
(2) neurofibrillary tangles
(3) cerebral amyloid angiopathy.
Neuritic plaques
Composed of deteriorating nerve pieces that arrange
themselves around a sticky protein core called amyloid beta
(aβ)
1|P a g e
, Neurofibrillary tangles
Formed by abnormal protein filaments called tau that wrap
around each other to form tangles
Cerebral amyloid angiopathy
Occurs when there is an abnormal accumulation of amyloid in
the blood vessels
Parkinson's disease
Neurodegenerative disease affecting the basal ganglia,
specifically an area called the substantia nigra (produces
dopamine)
Tricyclic antidepressants (tcas)
Blocking membrane receptors and the subsequent reuptake of
serotonin and norepinephrine
Monoamine oxidase inhibitors
Increase the concentration of serotonin and norepinephrine by
decreasing their degradation
