Neurological & Psychiatric Systems (Questions 1–
12)
1. A patient with severe Alzheimer's disease is
being switched from monotherapy to
combination therapy. Which medication can be
safely added to their existing cholinesterase
inhibitor regimen for late-stage management?
A) Galantamine
B) Rivastigmine
C) Memantine
D) Donepezil
Answer: C) Memantine
Rationale: Memantine is an NMDA receptor
antagonist approved specifically for moderate-
to-severe Alzheimer's disease. It has a
, completely distinct mechanism of action from
cholinesterase inhibitors, making it the ideal
add-on therapy to slow cognitive decline in
advanced stages.
2. A clinician is selecting a cholinesterase
inhibitor for a patient newly diagnosed with
mild-to-moderate dementia secondary to
Parkinson's disease. Which medication is
uniquely indicated for this dual presentation?
A) Donepezil
B) Rivastigmine
C) Memantine
D) Galantamine
Answer: B) Rivastigmine
Rationale: Rivastigmine is transdermal or oral
medication explicitly approved by the FDA to
treat mild-to-moderate dementia associated
with Parkinson's disease, as it targets both
acetylcholinesterase and butyrylcholinesterase.
3. A patient is brought to the emergency
department following a high-velocity motor
vehicle accident. A head CT reveals a crescent-
shaped hematoma crossing suture lines. What
is the most likely pathological diagnosis?
, A) Epidural hematoma
B) Subdural hematoma
C) Subarachnoid hemorrhage
D) Intracerebral hemorrhage
Answer: B) Subdural hematoma
Rationale: Subdural hematomas typically cross
suture lines and present as crescent-shaped
collections of blood, usually resulting from the
tearing of bridging veins. Epidural hematomas
are lens-shaped (biconvex) and do not cross
suture lines because they are bound by the
dura's attachments to the skull.
4. An emergency department CT scan of a patient
with head trauma demonstrates a biconvex,
lens-shaped collection of blood between the
skull and the dura mater. Which blood vessel is
most commonly lacerated in this condition?
A) Bridging veins
B) Middle meningeal artery
C) Basilar artery
D) Anterior communicating artery
Answer: B) Middle meningeal artery
Rationale: An epidural hematoma is
characterized by a biconvex/lens-shaped
, appearance on CT and is almost always caused
by a traumatic rupture of the middle meningeal
artery, often secondary to a temporal bone
fracture.
5. A 28-year-old male presents with acute,
positive symptoms of schizophrenia, including
auditory hallucinations and paranoid delusions.
The psychiatrist decides to initiate a first-
generation, low-potency typical antipsychotic.
Which drug fits this classification?
A) Haloperidol
B) Fluphenazine
C) Chlorpromazine
D) Olanzapine
Answer: C) Chlorpromazine
Rationale: Chlorpromazine is the prototype low-
potency first-generation (typical) antipsychotic.
Haloperidol and fluphenazine are high-potency
first-generation antipsychotics, while
olanzapine is a second-generation (atypical)
antipsychotic.
6. A patient suffering from chronic diabetic
peripheral neuropathy reports burning pain that
is unresponsive to over-the-counter NSAIDs.
