Describe what neurofibrillary tangles are, where they are
located, and why they are important. - ANSWER-
Neurofibrillary tangles are intracellular. They are tangled strands
of abnormal tau protein that interfere with normal intracellular
transport of nutrients and promote neural cell death.
List the brain functions that typically are lost first in Alzheimer
disease. - ANSWER-The brain functions that are typically lost
first in Alzheimer disease are learning and memory and thinking
and planning.
What do diffuse axonal injuries (DAIs) of the brain often result
in? - ANSWER-DAIs occur with all brain injuries and affect
neurons in widespread areas of the brain. Depending on severity,
this may result in altered or loss of consciousness.
Common causes of hemorrhagic strokes - ANSWER-
Hypertension, ruptured aneurysms or vascular malformation,
bleeding into a tumor, hemorrhage associated with bleeding
,2|Page
disorders, anticoagulation, head trauma, and illicit drug use are
common causes of hemorrhagic stroke
Risk factors for a stroke - ANSWER-General risk factors for
stroke include hypertension, cigarette smoking, diabetes, insulin
resistance, polycythemia and thrombocytopenia, presence of
lipoprotein-a, impaired cardiac function,
hyperhomocysteinemia, atrial fibrillation, and Chlamydia
pneumoniae
Select four causes of microcephaly from the list below. -
ANSWER-Autosomal recessive genetic alterations or defects in
any 1 of 16 chromosomes can cause primary microcephaly
(present at birth). Microcephaly may be caused by X-linked
genetic disorders with the altered gene on the X chromosome.
Environmental causes that include toxin exposure, radiation,
intrauterine infection, or chemical exposure may be the initiating
factor in secondary microcephaly. Maternal anorexia has been
shown to have an almost two-fold risk of microcephaly. Other
causes can include infection, trauma, metabolic disorders, and
the presence of other genetic syndromes.
What test do you do for a child with frequent headaches -
ANSWER-Headaches in children are unusual and require
investigation. Headaches and nausea in the morning may

indicate increased intracranial pressure. The pressure increases
while the head is in a dependent or flat position due to a
reduction in venous drainage. Intracranial pressure may decrease
once the head is no longer in a dependent or flat position as
venous drainage is improved and the contents of the cranium are
reduced. The FNP is likely worried that an increase in
intracranial pressure could indicate the presence of a brain
tumor.
Which three substances would a healthcare professional teach a
patient with a history of panic disorder to avoid? - ANSWER-
Panic-prone individuals respond to panicogens (chemicals that
produce panic symptoms), which include carbon dioxide,
caffeine, cholecystokinin, sodium lactate, and adrenergic
receptor agonists, such as yohimbine. Therefore, a healthcare
professional would advise a patient with a history of panic
disorder to avoid carbon dioxide and coffee and soda pop that
contain caffeine or to consider decaffeinated varieties of these
beverages.
For which neurotransmitter is there a decrease in receptor
binding found in individuals with depression? - ANSWER-
Decreased receptor binding for serotonin is found in major
depression.

Which monoamine findings are associated with mania? -
ANSWER-While the precise pathophysiology is not completely
understood, the monoamine theory of depression and
observational results related to the effect of medications on
monoamine levels suggests that low levels of monoamines are
associated with depression, while higher concentrations are
associated with mania.
Bipolar disorder increases what - ANSWER-Increased amygdala
volume, increased norepinephrien levels
Depression has decreased what levels - ANSWER-serotonin
A woman with a history of schizophrenia asks the nurse
practitioner, "Now that I am pregnant, how will my mental
illness affect my baby?"
Which statement is true regarding the effect on the woman's
child? - ANSWER-Schizophrenia is believed to be caused by
brain abnormalities that occur during the prenatal period of cell
proliferation and migration.
Openly defiant behavior that stands out against other children's
behavior and causes problems within the home and school is
oppositional defiant disorder.
