for the PMHNP | and Answers | Examplify Proctored
SECTION 1: FUNCTIONAL NEUROANATOMY
Question 1
A patient presents with expressive aphasia (difficulty producing speech) after a
stroke. Which area of the brain is most likely damaged?
A) Wernicke's area
B) Broca's area
C) Occipital lobe
D) Cerebellum
Answer: B) Broca's area
Rationale: Broca's area, located in the inferior frontal gyrus, is responsible for
speech production and language articulation. Damage causes expressive (non-
fluent) aphasia. Wernicke's area is for comprehension.
Question 2
The PMHNP is assessing a patient with damage to the parietal lobe. Which
symptom would the provider expect to find?
A) Auditory hallucinations
B) Inability to recognize objects by touch (astereognosis)
C) Impaired short-term memory
D) Personality changes
Answer: B) Inability to recognize objects by touch (astereognosis)
Rationale: The parietal lobe processes somatosensory information. Damage can
cause agnosia, including astereognosis (inability to identify objects by touch
alone). Auditory processing is temporal; memory is hippocampal; personality is
frontal.
Question 3
Which structure is part of the limbic system and is critical for transferring short-
term memory to long-term memory?
,A) Amygdala
B) Hippocampus
C) Thalamus
D) Hypothalamus
Answer: B) Hippocampus
Rationale: The hippocampus is essential for memory consolidation. The amygdala
is for emotion, the thalamus is a sensory relay, and the hypothalamus regulates
homeostasis.
Question 4
The orbitofrontal cortex (OFC) has a specific relationship with the amygdala. How
does the OFC influence the amygdala?
A) It only activates the amygdala
B) It only inhibits the amygdala
C) It both inhibits and activates the amygdala
D) It has no direct connection to the amygdala
Answer: C) It both inhibits and activates the amygdala
Rationale: The OFC is involved in reward/punishment and risk assessment. It has
bidirectional connections with the amygdala, allowing it to both activate and
inhibit amygdala responses based on context.
Question 5
Which lobe of the brain contains the primary visual cortex?
A) Frontal lobe
B) Temporal lobe
C) Parietal lobe
D) Occipital lobe
Answer: D) Occipital lobe
Rationale: The occipital lobe processes visual information. The frontal lobe
handles executive function, the temporal lobe handles hearing/memory, and the
parietal lobe handles somatosensory input.
,Question 6
The basal ganglia are involved in all of the following EXCEPT:
A) Voluntary motor movements
B) Cognition
C) Emotion
D) Speech comprehension
Answer: D) Speech comprehension
Rationale: Speech comprehension is a function of Wernicke's area in the
temporal lobe. The basal ganglia are involved in motor control, cognition, and
emotion (implicated in Parkinson's, OCD, Tourette's).
Question 7
What is the primary component of gray matter?
A) Myelinated axons
B) Neural cell bodies, dendrites, and synapses
C) Cerebrospinal fluid
D) Blood vessels
Answer: B) Neural cell bodies, dendrites, and synapses
Rationale: Gray matter consists of neuronal cell bodies, dendrites, and
synapses—it is the "processing" center. White matter consists of myelinated
axons that connect regions.
Question 8
Damage to Wernicke's area results in which type of aphasia?
A) Expressive aphasia
B) Receptive aphasia
C) Global aphasia
D) Conduction aphasia
Answer: B) Receptive aphasia
Rationale: Wernicke's area is responsible for language comprehension. Damage
, results in receptive (fluent) aphasia where the patient can speak but cannot
understand language.
Question 9
The thalamus serves as a:
A) Memory storage center
B) Emotional regulation center
C) Sensory relay station
D) Motor coordination center
Answer: C) Sensory relay station
Rationale: The thalamus relays sensory and motor signals to the cerebral cortex.
The hippocampus stores memory, the amygdala handles emotion, and the
cerebellum coordinates motor activity.
Question 10
Which brain structure is most associated with the "fight-or-flight" response and
fear conditioning?
A) Hippocampus
B) Amygdala
C) Prefrontal cortex
D) Nucleus accumbens
Answer: B) Amygdala
Rationale: The amygdala is central to fear processing, anxiety, and the fight-or-
flight response. The prefrontal cortex modulates this response, but the amygdala
generates it.
Question 11
The nucleus accumbens is a key structure in which circuit?
A) Nigrostriatal pathway
B) Mesolimbic reward pathway
