Identify the best response made by the psychiatric-mental health nurse practitioner
(PMHNP).
A “You have to take your medication to become stable.”
.
B “ Medications work by increasing the types of neurotransmitters produced by the human brain .”
.

1.
Ms. Hill is currently being treated for schizophrenia but has stopped taking
her medications due to some side effects she claims she was experiencing.
She presents to the clinic today with worsening symptoms. She is
experiencing anhedonia, agitation, attentional impairment, and affective
blunting. Which one of the symptoms mentioned is considered a positive
symptom of schizophrenia?

.
B Agitation
.
C Attentional Impairment
.
D Affective Blunting
.

QUE S TION 3
1. Which statement about neurotransmitters and medications is true?
A Endorphins were discovered before morphine which lead to the use of the opioids for pain
. control.
B Several psychiatric medications have been developed after discoveries of endogenous
. neurotransmitters and defining their function in the brain .
C Medications work by sending messages to neurotransmitters enabling them to work more
. effectively.
D An imbalance of serotonin has been directly linked to depression. Following the discovery of this
. neurotransmitter, pharmacologists were able to develop a well-known drug- Prozac as the first
medication used to restore the balance of serotonin .

QUE S TION 4
1. When an unstable patient asks why it is necessary to add medications to his current
regimen, the PMHNP’s best response would be:
A "More often than you would think, multiple medications should always be tried together to see
. what happens.”
B “Due to this being your first hospitalization after starting medication treatment for the first time
. in your life, the only way to effectively manage your symptoms is by adding additional
medications in hopes that it will work for you."
C “Many psychiatric illnesses involve several dys-functioning neurotransmitter systems in the
. brain. Often, a single medication may only effect one or two of the dys-functioning systems. The
addition of another medication can work with the current medication in stabilizing multiple
neurotransmitter systems and help to alleviate your symptoms.”
D “I understand your concerns. Often times, it is necessary to switch medications after short
. periods of time to better manage your symptoms. We will discontinue your current regimen and
start another single drug agent.”

QUE S TION 5
1. During gene expression, what must occur prior to a gene being expressed?
A Transcription factor must bind to the regulatory region within
. the cell’s nucleus.
, B RNA must be converted to mRNA.
.
C The coding region must separate from the regulatory region.
.
D RNA polymerase must inhibit the process of changing RNA to
. mRNA.

QUE S TION 6
1. While genes have potential to modify behavior, behavior can also modify genes. How
do genes impact this process?
A Genes impact neuron functioning directly.
.
B Changes made to proteins lead to changes in
. behavior.
C Neurons are able to impact protein synthesis.
.
D Genes impact the DNA of a cell, leading to
. changes in behavior.

QUE S TION 7
1. Though medications have the ability to target neurotransmitter release into the synapse
by the presynaptic neuron it is not always necessary. The PMHNP understands that this is
because:
A Neurotransmission occurring along the axon is normally at a level to prevent symptoms of
. mental illness and rarely require augmentation from medication therapy .
B Neurotransmission is minimally affected by medication therapy when compared to the baseline
. neurotransmitter release of a resting neuron .
C Neurotransmitters can spread by diffusion.
.
D The post synaptic neuron can produce and release its’ own neurotransmitter allowing it to
. function properly.

QUE S TION 8
1. Why is the cytochrome P450 enzyme system of significance to the PMHNP?
A The kidneys play a role with excretion of the medication, and if a patient has kidney
. damage, the dose must be increased to be effective.
B The bioavailability of the medication after it passes through the stomach and liver
. can be altered.
C The medication’s chemical composition changes when it comes in contact with the
. acid in the stomach.
, D The CYP enzyme system is a steady and predictable process that prescribers must
. understand to treat conditions effectively.

QUE S TION 9
1. It is important for the PMHNP to recognize differences in pharmacokinetics to safely
prescribe and monitor medications. Which of the following statements does the competent
PMHNP identify as true?
A About 1 out of 5 Asians requires lower-than-normal doses of some antidepressants
. and antipsychotics.
B The term polymorphic refers to the body’s ability to break a medication down several
. ways, and this patient may require higher doses of certain antidepressants and
antipsychotics.
C About 1 out of 30 Caucasians requires lower doses of some antidepressants and
. antipsychotics.
D Most enzyme pathways do not have interactions between the newer medications.

1. As it relates to G-protein linked receptors, what does the PMHNP understand about
medications that are used in practice?
A Most medications that act on G-protein linked receptors have antagonistic traits.
.
B The majority of medications used in practice are full agonists and are used to
. stimulate the body’s natural neurotransmitters.
C Most medications act as partial agonists because they allow the body to use only
. what is needed.
D Medications used in practice may act as inverse agonists if the dosage is too high.

.
B The patient has hypertension.
