Questions and Answers with Verified Rationales
SECTION 1: Neurobiological Foundations
1. Sam is a 78-year-old male diagnosed with Parkinson's disease. Which area of Sam's brain is
primarily affected in Parkinson's disease?
A. Hypothalamus
B. Septal nuclei
C. Basal ganglia
D. Amygdala
Answer: C. Basal ganglia
Rationale: Parkinson's disease results from the degeneration of dopamine-producing neurons in the
substantia nigra, which is part of the basal ganglia. This leads to the classic motor symptoms of tremor,
rigidity, and bradykinesia.
2. A 22-year-old college student is being treated for schizophrenia. The PMHNP explains that an excess
of which neurotransmitter is most strongly implicated in the positive symptoms of schizophrenia?
A. Serotonin
B. Norepinephrine
C. Dopamine
D. GABA
Answer: C. Dopamine
Rationale: The dopamine hypothesis of schizophrenia posits that hyperactivity of dopamine transmission
in the mesolimbic pathway contributes to positive symptoms such as hallucinations and delusions.
Antipsychotic medications work primarily by blocking D2 dopamine receptors.
3. A 45-year-old patient with major depressive disorder is started on an SSRI. The PMHNP explains
that this medication works by increasing the availability of which neurotransmitter at the
postsynaptic receptor sites?
A. Dopamine
B. Serotonin
C. Acetylcholine
D. Norepinephrine
Answer: B. Serotonin
Rationale: Selective serotonin reuptake inhibitors (SSRIs) block the reuptake of serotonin into the
,2
presynaptic neuron, thereby increasing the amount of serotonin available to bind to postsynaptic
receptors. Too little serotonin is associated with depression and some anxiety disorders.
4. Which neurotransmitter is the major inhibitory neurotransmitter in the central nervous system, and
a deficiency of it is associated with anxiety disorders?
A. Glutamate
B. Acetylcholine
C. GABA
D. Dopamine
Answer: C. GABA
Rationale: Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the CNS.
Benzodiazepines and other anxiolytics enhance GABA's calming effects. Too little GABA is linked to
anxiety and anxiety disorders.
5. The PMHNP is reviewing neuroanatomy with a student. The student correctly identifies that
executive functioning, working memory, planning, and insight are primarily functions of which brain
lobe?
A. Parietal lobe
B. Occipital lobe
C. Frontal lobe
D. Temporal lobe
Answer: C. Frontal lobe
Rationale: The frontal lobe, particularly the prefrontal cortex, is responsible for higher-order cognitive
functions including executive function, working memory, planning, judgment, and insight. Damage to
this area can result in significant personality and behavioral changes.
6. A patient who experienced a traumatic event has intrusive memories and heightened fear
responses. The PMHNP explains that which brain structure is primarily responsible for processing fear
and rage?
A. Amygdala
B. Hippocampus
C. Thalamus
D. Hypothalamus
Answer: A. Amygdala
Rationale: The amygdala is a key component of the limbic system and is responsible for processing
emotions, particularly fear, rage, and emotional memories. It plays a central role in the pathophysiology
of PTSD and anxiety disorders.

7. A patient with a traumatic brain injury has difficulty forming new memories and cannot recall what
happened earlier in the day. The PMHNP recognizes that this patient has likely sustained damage to
which brain structure?
A. Amygdala
B. Hippocampus
C. Basal ganglia
D. Cerebellum
Answer: B. Hippocampus
Rationale: The hippocampus is essential for learning and for processing information into long-term
memories, as well as assigning time and place to those memories. Bilateral hippocampal damage results
in profound anterograde amnesia.
8. The PMHNP is educating a patient about the role of norepinephrine. Which of the following
functions is associated with this neurotransmitter?
A. Pain relief and pleasure
B. Eating and alertness
C. Sleep and appetite regulation
D. Voluntary movement and memory
Answer: B. Eating and alertness
Rationale: Norepinephrine is involved in arousal, alertness, and the fight-or-flight response. It also plays
a role in regulating eating behavior. An excess has been associated with schizophrenia, while a deficiency
is linked to depression.
9. A patient is prescribed a benzodiazepine for acute anxiety. The PMHNP explains that this
medication works by enhancing the effects of which neurotransmitter?
A. Serotonin
B. Dopamine
C. GABA
D. Glutamate
Answer: C. GABA
Rationale: Benzodiazepines bind to GABA-A receptors and enhance the inhibitory effects of GABA,
resulting in sedation, anxiolysis, and muscle relaxation. They increase the frequency of chloride channel
opening.
10. A patient with Alzheimer's disease is prescribed a cholinesterase inhibitor. The PMHNP explains
that this medication aims to increase levels of which neurotransmitter in the brain?
A. Dopamine
B. Serotonin
, 4
C. Acetylcholine
D. Norepinephrine
Answer: C. Acetylcholine
Rationale: Acetylcholine is involved in learning, memory, and sleep. Too little acetylcholine in the
hippocampus is associated with dementia, including Alzheimer's disease. Cholinesterase inhibitors
prevent the breakdown of acetylcholine, thereby increasing its availability.
SECTION 2: Psychotherapeutic Theories and Modalities
11. A 35-year-old patient tells the PMHNP, "I feel like my life has no meaning. I go to work, come
home, and repeat the same thing every day. What's the point?" The PMHNP recognizes this as a core
concern best addressed by which therapeutic approach?
A. Cognitive-behavioral therapy
B. Gestalt therapy
C. Existential therapy
D. Behavioral therapy
Answer: C. Existential therapy
Rationale: Existential therapy focuses on universal features of the human condition, including the search
for meaning, the acceptance of pain as part of life, and the anxiety that arises from confronting the
"givens" of existence (death, freedom, isolation, meaninglessness).
12. According to Irvin Yalom, which of the following is NOT one of the four "ultimate concerns" or
"givens" of human existence?
A. Death
B. Freedom
C. Integrity
D. Existential isolation
Answer: C. Integrity
Rationale: Yalom identified four ultimate concerns: death, freedom, existential isolation, and
meaninglessness. Integrity is part of Erikson's psychosocial stages (ego integrity vs. despair), not Yalom's
existential framework.
13. The PMHNP is using Gestalt therapy techniques with a client who is experiencing internal conflict.
The therapist asks the client to imagine the critical part of themselves sitting in one chair and the
passive part in another, then engage in a dialogue. This technique is known as:
A. Topdog vs. Underdog
B. Empty chair technique
C. Dream work
D. Paradoxical intention
