What should the PMHNP consider when prescribing chemical restraints? - -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? - 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? - -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% lifetime risk of developing schizophrenia (Lemvigh et al., 2020). Why is
there only half the risk? - 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 - separates the frontal lobe from the parietal lobe
frontal lobe - associated with movement, intelligence, abstract thinking
broca's area - speech production
temporal lobe - involves object identification and auditory signals
cerebellum - coordination
wernicke's area - speech comprehension
occipital lobe - primary visual area
parietal lobe - keeps us alert to what is going on around us
,sensory cortex - pain, heat, and other sensations
motor cortex - movement
hippocampus - involved in both memory and anxiety
nucleus accumbens - involved in the reward process
thalamus - involved in sensory organ and motor command processing
striatum - involved in complex motor actions, also links cognition to motor actions
limbic system - includes circuits that are associated with pleasure and reward
basal ganglia - group of structures involved in voluntary motor movements
amygdala - involved in emotional regulation and perception of odors
corpus callosum - controls the communication between the two brain hemispheres
white matter - contains nerve fibers that connect neurons from different regions into
functional circuits
grey matter - contains nerve cells and dendrites
, brain tissue - made up of grey matter and white matter
dorsal striatum - 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: -
influenced by environmental factors and how epigenetics contributes to the
manifestation of mental illness
How does epigenetics impact a person's mental health? - 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
-genes being on or off
-occurrence of symptoms may be the result of inheritance of an abnormal gene or of normal
genes being "on" when they should be "off."
Types of epigenetic changes: - DNA Methylation
Histone modification
Non-coding RNA
The potential legal and ethical issues impacting mental health treatment must also be taken into
account, including: - -informed consent
-competence to make healthcare decisions
-off-label prescribing
