NURS 6630 PSYCHOPHARMACOLOGY MIDTERM EXAM
COMPLETE QUESTIONS WITH 100% VERIFIED
ANSWERS
1. A noncompliant patient states, "Why do you want me to put this poison in my
body?" Identify the best response made by the PMHNP.
A. "You are wrong. This medication will help you."
B. "All medications have side effects, but you need to take it."
C. "Most medications that work in the brain will result in restoring an imbalance of
one or more neurotransmitters that your body already produces helping to
alleviate your symptoms."
D. "If you don't take this, you will get much sicker."
Correct Answer: C
Explanation: This response provides psychoeducation, validates the patient's
concern without judgment, and explains the mechanism of action in a non-
threatening manner, improving therapeutic alliance and adherence.
2. 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?
A. Anhedonia
B. Agitation
C. Attentional impairment
D. Affective blunting
, Correct Answer: B
Explanation: Positive symptoms are an excess or distortion of normal functions
(agitation, hallucinations, delusions). Anhedonia, affective blunting, and
attentional impairment are negative or cognitive symptoms.
3. Which statement about neurotransmitters and medications is true?
A. Dopamine imbalance is the sole cause of all psychiatric disorders.
B. Serotonin has no role in depression.
C. Norepinephrine is only involved in attention deficit disorder.
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.
Correct Answer: D
Explanation: The serotonin hypothesis of depression led to the development of
fluoxetine (Prozac), the first SSRI. While earlier antidepressants existed (MAOIs,
TCAs), Prozac was the first selective serotonin reuptake inhibitor.
4. When an unstable patient asks why it is necessary to add medications to his
current regimen, the PMHNP's best response would be:
A. "Your current medication is not working, so we need to try something else."
B. "You will need to discuss this with your therapist."
C. "Many psychiatric illnesses involve several dysfunctional neurotransmitters in
the brain. Often, a single medication may only affect one or two of the
dysfunctional systems. The addition of another medication can work with the
current medication in stabilizing multiple neurotransmitter systems and help to
alleviate your symptoms."
D. "More medication is always better for unstable patients."
Correct Answer: C
Explanation: This response explains rational polypharmacy, targeting multiple
,neurotransmitter systems to improve symptom control, and provides patient-
centered education.
5. 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. The gene must mutate.
C. The cell must divide.
D. RNA polymerase must be degraded.
Correct Answer: A
Explanation: Transcription factors bind to promoter or enhancer regions of DNA in
the nucleus, recruiting RNA polymerase to initiate transcription, which is
necessary before a gene can be expressed.
6. While genes have potential to modify behavior, behavior can also modify
genes. How do genes impact this process?
A. Genes directly change behavior without any intermediate steps.
B. Changes made to proteins lead to changes in behavior.
C. Behavior has no impact on gene expression.
D. Genes only affect physical traits, not behavior.
Correct Answer: B
Explanation: Gene expression leads to protein synthesis, which affects neuronal
structure and function, ultimately influencing behavior. This is a bidirectional
process (epigenetics).
7. 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. Neurotransmitters are only active inside the neuron.
B. Receptors do not need neurotransmitters to function.
, C. Neurotransmitters can spread by diffusion.
D. Medications cannot reach the synapse.
Correct Answer: C
Explanation: Volume transmission allows neurotransmitters to diffuse through the
extracellular space to reach extrasynaptic receptors, so direct presynaptic release
targeting is not always required.
8. Why is the cytochrome P450 enzyme system of significance to the PMHNP?
A. It is only found in the brain.
B. The bioavailability of the medication after it passes through the stomach and
liver can be altered.
C. It has no effect on psychiatric medications.
D. It only affects over-the-counter drugs.
Correct Answer: B
Explanation: CYP450 enzymes (primarily in liver) metabolize most psychotropic
drugs. Genetic polymorphisms, drug interactions, and organ function affect
bioavailability, requiring dose adjustments.
9. 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. All ethnic groups metabolize medications identically.
C. Age does not affect pharmacokinetics.
D. Gender has no impact on drug metabolism.
Correct Answer: A
Explanation: Genetic polymorphisms in CYP2D6, CYP2C19, and other enzymes are
