NU 673 Midterm Exam Test Bank
2026/2027 (VERIFIED Q&A) –
Advanced PMHNP Care I
This is the most downloaded, 100% verified study
resource containing 300 actual exam-style questions
for the NU 673 Midterm. Each question features the
exact correct answer paired with a highly detailed,
evidence-based clinical rationale to ensure complete
mastery of advanced psychopharmacology,
neurobiology, and DSM-5-TR criteria. Join
thousands of PMHNP students who used this exact
high-yield test bank to secure an A on their midterm
exam
,Question 1:
During a mental status examination, a PMHNP notes that a patient answers questions
by providing excessive, unnecessary details but eventually returns to the original point.
How should the nurse practitioner document this thought process?
A) Tangentiality
B) Circumstantiality
C) Flight of ideas
D) Loose associations
Answer: B) Circumstantiality
Rationale: Circumstantiality involves a thought pattern where the speaker includes a
high volume of tedious, irrelevant details before finally reaching the goal or answering
the original question. In contrast, tangential thoughts drift off-topic entirely and never
return to the initial prompt.
Question 2: A patient presenting with severe agitation and hyperthermia is suspected
of having Neuroleptic Malignant Syndrome (NMS) versus Serotonin Syndrome. Which
neurobiological mechanism drives the primary pathophysiological presentation of
Neuroleptic Malignant Syndrome?
A) Sudden drop or block of Dopamine (D2) receptors
B) Massive hyper-activation of 5-HT2A receptors
C) Complete degradation of Acetylcholine at the neuromuscular junction
D) Downregulation of Gamma-Aminobutyric Acid (GABA) pathways
Answer: A) Sudden drop or block of Dopamine (D2) receptors
Rationale: Neuroleptic Malignant Syndrome (NMS) is an idiosyncratic reaction to
antipsychotic medications caused by an acute drop in central dopamine activity or
excessive dopamine receptor blockade. This differentiates it from Serotonin Syndrome,
which is driven by an excess of serotonin activity.
Question 3: During a specialized neurological assessment, the PMHNP evaluates the
structures responsible for regulating core homeostatic functions, including body
temperature, heart rate, fluid balance, and emotional behaviors like anger and sex drive.
Which region of the diencephalon is responsible for these functions?
A) Thalamus
B) Basal ganglia
C) Cerebral cortex
D) Hypothalamus
,Answer: D) Hypothalamus
Rationale: The hypothalamus maintains systemic homeostasis by directly regulating
temperature, fluid balance, blood pressure, and sleep-wake cycles, while also serving
as a major link to the endocrine system and governing instinctual emotional behaviors.
The thalamus acts primarily as a sensory relay station.
Question 4: A 67-year-old patient presents with new-onset depressive symptoms,
including psychomotor slowing and memory lapses. What clinical reasoning must guide
the PMHNP's initial approach to diagnostic formulation?
A) Initiate immediate psychotropic medication management tailored for older adults
B) Order full cognitive mapping and immediate physical therapy referrals
C) Complete a comprehensive physical assessment and labs to rule out medical mimics
D) Diagnose Major Depressive Disorder based exclusively on DSM-5-TR subjective
criteria
Answer: C) Complete a comprehensive physical assessment and labs to rule out
medical mimics
Rationale: In psychiatric care, medical conditions (such as hypothyroidism, B12
deficiency, or neurodegenerative changes) must always be ruled out first because many
medical issues directly mimic psychiatric illness. This rule is especially critical in older
populations where depression is frequently underrecognized or confounded by
comorbid conditions.
Question 5: When performing a comprehensive cranial nerve evaluation on a patient
presenting with an altered gait and headaches, the PMHNP tests the functions of the
peripheral nervous system (PNS). How many pairs of spinal nerves attach directly to the
spinal cord to carry sensory and motor signals?
A) 12 pairs
B) 31 pairs
C) 7 pairs
D) 43 pairs
Answer: B) 31 pairs
Rationale: The peripheral nervous system includes 31 pairs of spinal nerves that attach
directly to the spinal cord: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 1 coccygeal.
Each spinal nerve contains both anterior (motor) and posterior (sensory) roots.
, Question 6: A 42-year-old patient diagnosed with treatment-resistant schizophrenia is
being initiated on clozapine. Which of the following laboratory values represents the
absolute minimum absolute neutrophil count (ANC) required to safely initiate this
medication?
A) 1,000 cells/mm³
B) 1,500 cells/mm³
C) 2,000 cells/mm³
D) 3,500 cells/mm³
Answer: B) 1,500 cells/mm³
Rationale: According to FDA safety guidelines, the absolute neutrophil count (ANC)
must be greater than or equal to 1,500 cells/mm³ (or ≥1,000 cells/mm³ for individuals
with documented Benign Ethnic Neutropenia) before initiating clozapine due to the
severe risk of agranulocytosis.
Question 7: A PMHNP is conducting a cranial nerve examination. When assessing a
patient's ability to smile, frown, and puff out their cheeks symmetrically, which cranial
nerve is being directly evaluated?
A) Cranial Nerve V (Trigeminal)
B) Cranial Nerve VII (Facial)
C) Cranial Nerve IX (Glossopharyngeal)
D) Cranial Nerve X (Vagus)
Answer: B) Cranial Nerve VII (Facial)
Rationale: Cranial Nerve VII (the Facial nerve) is responsible for motor control of facial
expression, including smiling, frowning, and puffing the cheeks. Cranial Nerve V
handles facial sensation and mastication.
Question 8: A 28-year-old female patient presents with rapid, pressurized speech,
grandiosity, and a decreased need for sleep lasting for the past 5 consecutive days. Her
symptoms cause clear, marked impairment in social and occupational functioning but do
not require hospitalization. What is the most appropriate DSM-5-TR diagnosis?
A) Bipolar I Disorder, Manic Episode
B) Bipolar II Disorder, Hypomanic Episode
C) Cyclothymic Disorder
D) Major Depressive Disorder with Mixed Features
Answer: A) Bipolar I Disorder, Manic Episode
