The Ultiṃate Study Guide to Pass Your Exaṃ
Inside, you'll get:
➢Key areas to f̣ ocus on in your NR 546 study
guide:➢Review course:
➢Review notes:
➢Practice questions with answers:
➢Case studies:
➢key terṃs and def̣ initions:
,1. How does reviewing the genetic makeup of̣ a client help guide the PMHNP in
selecting medication f̣ or clients
Answer>-Genetic testing can assist by providing more inf̣ormation on
how clients may respond to certain psychotropic medications
-provides inf̣ormation on how a client may break down and metabolize
medications based on the cytochrome P450 system.
2. Tanr1kulu and Erba_ (2020) investigated identical twins to determine the
presence of̣ an inherited link f̣ or 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 of̣ identical Danish twins f̣ ound that if̣ one twin had schizophrenia,
the other twin had a 50% lif̣ etime risk of̣ developing schizophrenia (Lemvigh
et al., 2020). Why is there only half̣ the risk
Answer>Both environmental and psychosocial stressors can im- pact
mental health. Although twins may have identical genes, their gene
expression may be dif̣fe
̣ rent.
There may be an environmental exposure that turned a gene "on" that
should have been "of̣f"̣ f̣or one twin to develop schizophrenia and not
the other.
3. The f̣ ield of̣ epigenetics is rapidly growing and can help explain how
gene expression is
Answer>inf̣luenced by environmental f̣actors and how epigenetics
,contributes to the manif̣estation of̣ mental illness
, 4. How does epigenetics impact a person's mental health
Answer>internal or external f̣actors activate portions of̣ the genome that
result in the manif̣estation of̣ mental health symptoms
-activation is of̣ten a result of̣ a stressf̣ul event, which, when combined
with the genetic risk, results in the disease
-genes being on or of̣f ̣
-occurrence of̣ symptoms may be the result of̣ inheritance of̣ an
abnormal gene or of̣ normal genes being "on" when they should be
"of̣f.̣ "
5. Types of̣ epigenetic changes
Answer>DNA Methylation Histone
modif̣ication Non-coding RNA
6. The potential legal and ethical issues impacting mental health
treatment must also be taken into account, including
Answer>-inf̣ormed consent
-competence to make healthcare decisions
-of̣f-̣ label prescribing
7. What should the PMHNP consider when prescribing chemical
restraints Answer> -
-allergy status
