[SECTION 1: Neurobiology & Psychopharmacology — Questions 1-18]
Q1: The PMHNP understands that the mesocortical dopamine pathway is primarily responsible
for which symptom cluster in schizophrenia?
A. Hallucinations and delusions
B. Alogia and avolition
C. Tremors and rigidity
D. Hyperprolactinemia and galactorrhea
Correct Answer: B
Rationale: The mesocortical pathway projects from the ventral tegmental area to the prefrontal
cortex. Underactivity or blockade of this pathway is associated with negative symptoms (e.g.,
alogia, avolition, flat affect) and cognitive impairments. Option A describes the mesolimbic
pathway (positive symptoms). Option C describes the nigrostriatal pathway (extrapyramidal
symptoms). Option D describes the tuberoinfundibular pathway (prolactin release).
Q2: A patient taking an SSRI presents with confusion, agitation, hyperreflexia, and fever. The
PMHNP recognizes these as potential signs of:
A. Neuroleptic Malignant Syndrome (NMS)
B. Serotonin Syndrome
C. Tardive Dyskinesia
D. Acute Dystonia
Correct Answer: B
,2
Rationale: Serotonin Syndrome is a potentially life-threatening condition caused by excessive
serotonergic agonism, characterized by a triad of cognitive changes (agitation, confusion),
autonomic instability (fever, tachycardia), and neuromuscular hyperactivity (hyperreflexia,
clonus). Option A (NMS) is associated with antipsychotics and presents with lead-pipe rigidity.
Option C involves involuntary movements of the face/tongue. Option D involves sustained
muscle spasms.
Q3: Which instruction is most critical for a patient prescribed Phenelzine (Nardil), an MAOI?
A. Avoid foods high in tyramine, such as aged cheese and cured meats
B. Take the medication only at bedtime to avoid drowsiness
C. Stop the medication immediately if a dry cough develops
D. Ensure adequate intake of green leafy vegetables for Vitamin K
Correct Answer: A
Rationale: MAOIs inhibit the breakdown of tyramine in the gut. Ingesting tyramine-rich foods
can cause a hypertensive crisis, characterized by dangerously high blood pressure. Options B, C,
and D are not the primary safety concerns; the dietary restriction is the hallmark of MAOI
therapy education.
Q4: The PMHNP is teaching a patient about Lithium toxicity. Which statement indicates the
patient understands the teaching?
A. "I should stop taking the medication if I feel nauseated."
B. "I need to report diarrhea, persistent vomiting, or tremor immediately."
C. "It is safe to take ibuprofen for my back pain while on this medication."
D. "I only need to have my blood levels checked once a year."
Correct Answer: B
Rationale: Early signs of Lithium toxicity include fine tremor, nausea, vomiting, and diarrhea.
These require immediate medical attention to prevent progression to seizures, coma, or death.
Option A is dangerous because abrupt cessation can cause rebound mania; the provider should be
notified first. Option C is incorrect because NSAIDs like ibuprofen can increase Lithium levels.
,3
Option D is incorrect because levels are monitored frequently, especially initially and during
dose changes.
Q5: Which side effect is most commonly associated with the atypical antipsychotic Clozapine
(Clozaril), requiring mandatory blood monitoring?
A. Metabolic syndrome
B. Agranulocytosis
C. Tardive Dyskinesia
D. Neuroleptic Malignant Syndrome
Correct Answer: B
Rationale: Clozapine carries a risk of agranulocytosis, a potentially fatal blood disorder.
Consequently, patients must be enrolled in a REMS program and undergo weekly (for the first 6
months) and then bi-weekly ANC (Absolute Neutrophil Count) monitoring. While metabolic
syndrome (Option A) is also common with atypicals, agranulocytosis is unique to Clozapine
regarding monitoring mandates.
Q6: A patient with depression is switched from an SSRI to Venlafaxine (Effexor). The PMHNP
warns the patient about which dose-dependent side effect?
A. Seizures
B. Hypertension
C. Priapism
D. Severe constipation
Correct Answer: B
Rationale: Venlafaxine is an SNRI that affects norepinephrine reuptake. At higher doses
(typically >150 mg/day), it inhibits norepinephrine more significantly, which can lead to
sustained hypertension. Options A and C are associated with Bupropion and Trazodone,
respectively. Option D is less specific than the hypertensive risk associated with SNRIs.
, 4
Q7: When initiating Lamotrigine (Lamictal) for Bipolar maintenance, the PMHNP must follow a
specific titration schedule to avoid:
A. Stevens-Johnson Syndrome (SJS)
B. Hepatotoxicity
C. Renal failure
D. Neuroleptic Malignant Syndrome
Correct Answer: A
Rationale: Lamotrigine carries a risk of severe rash, including Stevens-Johnson Syndrome and
Toxic Epidermal Necrolysis. This risk is significantly reduced by slow, gradual titration of the
dose (e.g., starting at 25 mg and increasing slowly every 1-2 weeks). Options B and C are risks
of other mood stabilizers (Valproate and Lithium, respectively).
Q8: A patient with schizophrenia presents with muscle rigidity, fever, autonomic instability, and
elevated CPK. The PMHNP suspects Neuroleptic Malignant Syndrome (NMS). What is the
priority intervention?
A. Administer an anticholinergic medication
B. Immediately stop the antipsychotic and provide supportive care
C. Increase the dose of the antipsychotic to control agitation
D. Administer a benzodiazepine only
Correct Answer: B
Rationale: NMS is a medical emergency. The first step is immediate discontinuation of the
antipsychotic medication and providing aggressive supportive care (hydration, cooling,
monitoring). While bromocriptine or dantrolene may be used, stopping the causative agent is the
priority. Options A and D address symptoms but not the root cause. Option C would be fatal.
Q9: The PMHNP prescribes Buspirone (Buspar) for Generalized Anxiety Disorder. How does the
onset of action compare to benzodiazepines?
A. It is faster acting than benzodiazepines
