/. 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% 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
/.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
/.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
-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: - Answer-✅DNA Methylation
Histone modification
Non-coding RNA
/.The potential legal and ethical issues impacting mental health treatment must also be
taken into account, including: - Answer-✅-informed consent
-competence to make healthcare decisions
-off-label prescribing
/.Informed consent - Answer-✅Clients have the right to receive enough information to
make decisions about treatment.
-must also be informed about potential risks associated with medications.
-have the right to refuse treatment
-cannot be forcibly medicated in non-emergencies. However, clients can be forcibly
medicated if they are violent toward themselves or others and when less restrictive
methods have failed
/.Compliance - Answer-✅A court order may be issued for a client to receive treatment
against their wishes if they are considered a danger to themselves or others.
-Examples: clients with schizophrenia or sex offenders
-Guardians can provide consent for clients who have limited cognitive capabilities or are
incompetent to make decisions
-PMHNPs are responsible for being knowledgeable about their state laws and abiding
by them.
/.Off-Label Prescribing - Answer-✅Some clients may benefit from the unapproved use
of a drug for symptom management.
-Example: many SSRIs used to tx anxiety and OCD but are not FDA approved for use
in this disorder.
-potentially raises ethical and legal concerns
-PMHNP must remain up to date with the latest recommendations for off-label
prescribing.
, /.Incidence of mental illness-what factors are increasing the incidence - Answer-
✅Psychological and sociological factors
Lifestyle factors such as a client's smoking status, diet, exercise, history of medication
adherence, or history of addiction should be considered when prescribing psychotropic
medications
/.Adherence - Answer-✅Persistence
-taking med over intended time period
Compliance
-taking med as prescribed
/.left hemisphere - Answer-✅-speech comprehension
-word recognition
-grammar
-sequential processing
-recognition of detail
-conscious mental processing
/.right hemisphere - Answer-✅-prosody of speech
-emotional modulation
-visual-spatial skills
-recognition of facial expression
-music
-abstract mathematical skills
-holistic processing
-unconscious mental processing
/.Pharmacokinetics - Answer-✅the study of what happens to a drug from the time of
administration until the parent drug and all metabolites leave the body
/.CYP450 - Answer-✅CYP450 enzymes in the gut wall or liver convert drug substrate
into a biotransformed product in the bloodstream, responsible for degradating of a large
# of psychotropic drugs
-Not all ind. have same genetic form of CYP450 enzymes, determined with
pharmacogenetic testing
*Most individuals have "normal" rates of drug metabolism from the major CYP450
enzymes and are said to be "extensive metabolizers", most drug doses are set for these
individuals.
*genetic variants of these enzymes can make poor metabolizers or ultra rapid
metabolizers
Five of the most important:
CYP450 1A2, 2B6, 2D6, 2C9, 2C19, and 3A4.
