EXAM QUESTIONS AND CORRECT DETAILED ANSWERS
(VERIFIED ANSWERS) ALREADY GRADED A+ (MOST RECENT!!)
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
, 4|Page
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.
A patient comes in for their follow-up after 30 days on Effexor Extended
Release (XR) 150 mg by mouth every morning for major depressive
disorder. The patient tells their psychiatric mental health nurse
practitioner (PMHNP) that they feel great and have accomplished so
many things in the past week that they feel like they can do anything
now. The patient shows the PMHNP a plan they have made to start
their own business. The patient has been staying up late writing down
their ideas for their business plan, and they show you a very
disorganized list of seemingly unrelated items. The PMHNP tries to ask
