What should the PMHNP consider when prescribing chemical restraints? -
(ANSWER)-allergy status
-prior med hx for adverse drug reactions r/t the meds ordered in the chemical
restraint
-state regulations regarding chemical restrains must be reviewed
Are the PMHNP and other staff liable if the client has an allergic reaction or
adverse side effects to the drugs used for chemical restraint? - (ANSWER)No.
The client has been court-ordered to take the prescribed medications and the
standing order for chemical restraints is approved. The PMHNP and other staff
are not liable if the patient has an allergic reaction or adverse side effects.
How does reviewing the genetic makeup of a client help guide the PMHNP in
selecting medication for clients? - (ANSWER)-Genetic testing can assist by
providing more information on how clients may respond to certain psychotropic
medications
-provides information on how a client may break down and metabolize
medications based on the cytochrome P450 system.
Tanrıkulu and Erbaş (2020) investigated identical twins to determine the presence
of an inherited link for schizophrenia and why one twin may develop
schizophrenia when the other does not. When two people have 100% identical
DNA, why don't both persons develop the exact illnesses? Studies of identical
Danish twins found that if one twin had schizophrenia, the other twin had a 50%
, 2
lifetime risk of developing schizophrenia (Lemvigh et al., 2020). Why is there only
half the risk? - (ANSWER)Both environmental and psychosocial stressors can
impact mental health. Although twins may have identical genes, their gene
expression may be different.
There may be an environmental exposure that turned a gene "on" that should
have been "off" for one twin to develop schizophrenia and not the other.
central sulcus - (ANSWER)separates the frontal lobe from the parietal lobe
frontal lobe - (ANSWER)associated with movement, intelligence, abstract thinking
broca's area - (ANSWER)speech production
temporal lobe - (ANSWER)involves object identification and auditory signals
cerebellum - (ANSWER)coordination
wernicke's area - (ANSWER)speech comprehension
occipital lobe - (ANSWER)primary visual area
parietal lobe - (ANSWER)keeps us alert to what is going on around us
, 3
sensory cortex - (ANSWER)pain, heat, and other sensations
motor cortex - (ANSWER)movement
hippocampus - (ANSWER)involved in both memory and anxiety
nucleus accumbens - (ANSWER)involved in the reward process
thalamus - (ANSWER)involved in sensory organ and motor command processing
striatum - (ANSWER)involved in complex motor actions, also links cognition to
motor actions
limbic system - (ANSWER)includes circuits that are associated with pleasure and
reward
basal ganglia - (ANSWER)group of structures involved in voluntary motor
movements
amygdala - (ANSWER)involved in emotional regulation and perception of odors
, 4
corpus callosum - (ANSWER)controls the communication between the two brain
hemispheres
white matter - (ANSWER)contains nerve fibers that connect neurons from
different regions into functional circuits
grey matter - (ANSWER)contains nerve cells and dendrites
brain tissue - (ANSWER)made up of grey matter and white matter
dorsal striatum - (ANSWER)involved in complex motor actions and linkage of
cognition to motor actions
-main input area for basal ganglia
*activated when anticipating or engaging in pleasure
The field of epigenetics is rapidly growing and can help explain how gene
expression is: - (ANSWER)influenced by environmental factors and how
epigenetics contributes to the manifestation of mental illness
How does epigenetics impact a person's mental health? - (ANSWER)internal or
external factors activate portions of the genome that result in the manifestation
of mental health symptoms
-activation is often a result of a stressful event, which, when combined with the
genetic risk, results in the disease
