NR 546 WEEK 4 MIDTERM EXAM (ADVANCED PSYCHOPHARMACOLOGY FOR THE PMHNP) QUESTIONS
AND ANSWERS ALREADY GRADED A+. 100% VERIFIED SOLUTIONS | UPDATED PER LATEST GUIDELINES |
GRADED A+...
CORE DOMAINS
• Neurobiological Foundations of Psychiatric Disorders
• Pharmacokinetics and Pharmacodynamics
• Antidepressant and Anxiolytic Agents
• Antipsychotic Medications and Movement Disorders
• Mood Stabilizers and Anticonvulsants
• Treatment of Special Populations (Pediatric, Geriatric, Pregnancy)
• Drug–Drug Interactions and Adverse Effect Management
• Ethical and Legal Considerations in Psychopharmacology
INTRODUCTION
This examination evaluates advanced psychopharmacology knowledge essential for the PMHNP role. Content
spans neurobiology, pharmacokinetics, pharmacodynamics, and clinical application of psychotropic agents across
the lifespan. The multiple‑choice format includes scenario‑based and knowledge‑focused items that require critical
thinking, evidence‑based decision‑making, and safe prescribing practices. Items assess competence in selecting,
monitoring, and managing psychopharmacological interventions for major psychiatric disorders. The examination
mirrors the rigor of graduate‑level midterm assessments and board certification preparation, emphasizing both
foundational science and real‑world clinical reasoning.
,SECTION ONE: Questions 1–75
1. Which neurotransmitter system is primarily targeted by selective serotonin reuptake inhibitors (SSRIs)?
A. Norepinephrine
B. Dopamine
C. Serotonin
D. Gamma‑aminobutyric acid (GABA)
🟢 Correct Answer:
C
🔴 RATIONALE:
SSRIs block the serotonin transporter (SERT), inhibiting reuptake of serotonin into presynaptic neurons, thereby
increasing synaptic serotonin levels. Norepinephrine is targeted by SNRIs; dopamine by NDRIs; GABA by
benzodiazepines.
2. A patient on fluoxetine develops serotonin syndrome after taking an additional serotonergic agent. Which
triad of symptoms is most characteristic?
A. Confusion, ataxia, nystagmus
B. Neuromuscular excitation, autonomic instability, altered mental status
C. Bradycardia, hypotension, miosis
D. Hyperthermia, dry skin, muscle rigidity
🟢 Correct Answer:
B
,🔴 RATIONALE:
Serotonin syndrome features neuromuscular hyperactivity (clonus, hyperreflexia), autonomic instability
(tachycardia, hyperthermia), and mental status changes. Option A suggests Wernicke encephalopathy; D might
suggest neuroleptic malignant syndrome (NMS) with lead‑pipe rigidity and dry skin, but NMS usually presents
with bradyreflexia and severe hyperthermia with diaphoresis less prominent.
3. Which antipsychotic has the highest risk of agranulocytosis and requires regular white blood cell monitoring?
A. Risperidone
B. Olanzapine
C. Clozapine
D. Quetiapine
🟢 Correct Answer:
C
🔴 RATIONALE:
Clozapine carries a boxed warning for severe neutropenia/agranulocytosis, requiring absolute neutrophil count
(ANC) monitoring before initiation, weekly during the first 6 months, and then periodically. No other atypical
antipsychotic has this requirement.
4. The PMHNP prescribes lamotrigine for bipolar maintenance. What serious adverse effect requires immediate
cessation if a rash appears?
A. Hypertensive crisis
, B. Stevens‑Johnson syndrome
C. Pancreatitis
D. Renal failure
🟢 Correct Answer:
B
🔴 RATIONALE:
Lamotrigine can cause severe cutaneous reactions including Stevens‑Johnson syndrome and toxic epidermal
necrolysis. Any rash, especially if accompanied by fever or mucosal involvement, warrants immediate
discontinuation. Slow titration reduces risk.
5. A patient with generalized anxiety disorder has not responded to SSRIs. The PMHNP considers buspirone.
Which statement about buspirone is accurate?
A. It carries a high risk of physical dependence.
B. It has a rapid onset of action similar to benzodiazepines.
C. It is a partial agonist at serotonin 5‑HT1A receptors.
D. It is a first‑line treatment for panic disorder.
🟢 Correct Answer:
C
🔴 RATIONALE:
Buspirone is a 5‑HT1A partial agonist with anxiolytic effects, no significant risk of dependence, and a slower
onset (2–4 weeks). It is not first‑line for panic disorder and is not a benzodiazepine.
