CYP450 inhibitors - ANSWER bupropion, clomipramine, cimetidine,
clarithromycin, fluoroquinolone, grapefruit, ketoconazole, nefazodone, SSRIs
CYP450 inducers - ANSWER carbamazepine, nicotine (tobacco) hypericum (St.
John's wort), phenytoin, phenobarbital
CYP450 inducers do what - ANSWER Speed up drug metabolism leading to
decreased drug levels
CYP450 Inhibitors do what - ANSWER Slow down drug metabolism leading to
increased drug levels
Agonist effect - ANSWER Drug binds to receptors and activates a biological
response
Inverse agonist effect - ANSWER Drug causes the opposite effect of agonist;
binds to same receptor
Partial agonist effect - ANSWER Drug does not fully activate the receptors
, Antagonist effect - ANSWER Drug binds to the receptor but does not activate a
biological response - blocks
Controlled substances: Schedule I - ANSWER High abuse potential and no
accepted medical use (heroin, marijuana, LSD). Not legally available for
prescription
When a psychiatric mental health nurse practitioner participates in research and
quality assurance measures, the effectiveness of nursing practice can be evaluated
and documented. What is the goal of the research and quality assurance measure? -
ANSWER Establishing evidence-based practices and cost-containment practices.
By initiating research and quality assurance measures, the effectiveness of nursing
practice can be evaluated and documented, and evidence-based and cost-
containment practices can be established.
What distinguishes the professional role of the psychiatric mental health nurse
practitioner from other healthcare providers? - ANSWER Training in the combined
use of pharmaceuticals and psychotherapy. The PMHNP is uniquely qualified to
provide both treatment modalities using pharmaceuticals and psychotherapy.
Referring to the Chelsea Sutton video, how might you describe the age range of
patients of a psychiatric mental health nurse practitioner (PMHNP) and the
maximum duration of interaction PMHNPs might have with patients over the
patients' lifetime? - ANSWER PMHNPs may work with children and adults, unlike
other providers who may have a specialized age range. In addition, PMHNPs may
conceivably work with patients throughout their lifetime to restore or enhance
mental health and overall functioning.
What was Hildegard Peplau known for in the field of mental health? - ANSWER
Hildegard Peplau, considered the founder of advanced practice psychiatric nursing,
collaborated with Harry Stack Sullivan, MD. Peplau developed and implemented a
,role requiring master's-level preparation for all nurses who provide direct care to
psychiatric (mental health) patients.
Building on Peplau's work, what was Sara Robinson's greatest contribution to the
field of PMHNPs? - ANSWER Sara Robinson's greatest contribution is that she
paved the way for nurses to provide mental healthcare to patients.
Synapses are said to be asymmetric because communication is structurally
designed to be in one direction. - ANSWER True
In the reading, you learned about chemical neurotransmission. The authors
described how some neurotransmitters are similar to drugs. Describe why this is
important when considering a particular drug therapy for a psychiatric patient. -
ANSWER When selecting drugs for a patient, it is important to consider the
patient's background regarding drugs (e.g., allergic reactions, effectiveness, side
effects) and possible interaction with other prescribed drugs. However, psychiatric
mental health nurse practitioners (PMHNPs) should also consider the impact of the
patient's neurotransmitters, particularly those that are similar to drugs, as they may
affect the efficacy of any drug therapy.
What are the four categories of neurotransmitters? - ANSWER 1. Amino acids,
monoamines, acetylcholine, nitric oxide
Research supporting the utilization of psychotherapy in major depressive disorder
(MDD) does not have a benefit. - ANSWER False. The results of the systematic
review and meta-analysis by Guidi and Fava (2021) indicate that the sequential
integration of psychotherapy following response to acute-phase pharmacotherapy,
alone or combined with antidepressant medication, was associated with reduced
risk of relapse and recurrence in MDD.
, What are the cells of chemical neurotransmission called in the brain? - ANSWER
1. Neurons. Neurons are the cells of chemical communication in the brain. Human
brains are composed of tens of billions of neurons, and each is linked to thousands
of other neurons.
What is the study of the magnitude and variation of a drug response called? -
ANSWER Pharmacodynamics. The study of the magnitude and variation of drug
response is the definition of pharmacodynamics. Psychodynamics is the study of
what the body does to a drug and helps explain the relationship between the dose
and response.
A psychiatric mental health nurse practitioner (PMHNP) is working with an eight -
year-old patient. The PMHNP is considering prescribing a specific drug to the
patient, but the drug label does not include any information regarding
recommendations for pediatric patients. What should determine whether the
PMHNP should prescribe the drug to this patient? - ANSWER The need for the
drug and the common, acceptable use of this drug (standard of care). When
evidence-based practice guidelines are not available, PMHNPs should utilize the
current standard of care in mental health practice.
A psychiatric mental health nurse practitioner (PMHNP) is treating an 85-year-old
healthy male patient. What would affect the prescribed dose of a particular oral
drug? - ANSWER Age-related hepatic changes. Pharmacokinetics age-related
hepatic changes will affect the half-life of some drugs, especially those that require
both metabolism and excretion, which may be remarkably long in older people.
A signal transduction cascade passes its message from an extracellular first
messenger to an intracellular second messenger. In the case of the G-protein-linked
systems, what is the second messenger? - ANSWER Chemical. The second
messenger is a chemical in the case of G-protein-linked systems in the brain.
