(Questions 1 - 35)
Question 1
A PMHNP is evaluating a patient presenting with severe executive dysfunction, blunted affect, and
difficulty planning daily activities following a motor vehicle accident. Which brain region and
associated circuit are primarily impaired?
A. Orbitofrontal cortex and ventral tegmental area
B. Dorsolateral prefrontal cortex (DLPFC) and mesocortical pathway
C. Anterior cingulate cortex and nigrostriatal pathway
D. Ventromedial prefrontal cortex and mesolimbic pathway
Correct Answer: B
RATIONALE:
The dorsolateral prefrontal cortex (DLPFC) is the chief executive center of the brain responsible for working
memory, planning, organization, and problem-solving. Hypofunction or structural damage to the DLPFC and its
projections via the mesocortical pathway directly causes executive dysfunction and negative cognitive
symptoms. The orbitofrontal cortex regulates impulsivity, while the anterior cingulate manages selective
attention and emotional expression.
, Question 2
A patient experiencing chronic severe stress demonstrates persistently elevated cortisol levels. Which
neuroendocrine axis dysregulation is responsible for this presentation, and what structural
hippocampal change is typically observed over time?
A. Hypothalamic-Pituitary-Adrenal (HPA) axis; atrophy of hippocampal neurons due to excitotoxicity
B. Hypothalamic-Pituitary-Thyroid (HPT) axis; hypertrophy of dentate gyrus granule cells
C. Sympathomedullary axis; decreased glial cell migration in the subventricular zone
D. Hypothalamic-Pituitary-Gonadal (HPG) axis; increased neurogenesis in the CA3 region
Correct Answer: A
RATIONALE:
Chronic stress leads to sustained hyperactivation of the Hypothalamic-Pituitary-Adrenal (HPA) axis, causing
prolonged release of corticotropin-releasing hormone (CRH) and cortisol. Hypercortisolemia causes
excitotoxicity, loss of dendritic spines, and eventual atrophy of hippocampal neurons. The hippocampus
provides negative feedback to the HPA axis; its degeneration further impairs stress regulation.
Question 3
During G-protein coupled receptor (GPCR) signal transduction, what immediate intracellular event
occurs following the activation of the Gs protein subunit by an agonist?
A. Inhibition of adenylyl cyclase and decreased cyclic AMP (cAMP) production
B. Stimulation of adenylyl cyclase and increased cyclic AMP (cAMP) production
C. Activation of phospholipase C leading to inositol triphosphate (IP3) cleavage
D. Direct influx of extracellular chloride ions via ligand-gated channels
Correct Answer: B
RATIONALE:
Gs (stimulatory) G-proteins activate adenylyl cyclase, which converts ATP into cyclic AMP (cAMP). Increased
cAMP subsequently activates Protein Kinase A (PKA) to trigger downstream gene transcription (e.g., CREB).
Conversely, Gi (inhibitory) proteins inhibit adenylyl cyclase, while Gq proteins stimulate phospholipase C.
