INTRODUCTION
This examination assesses the advanced practice psychiatric-mental
health nursing knowledge and clinical decision-making skills
required for safe, evidence-based practice. It evaluates diagnostic
reasoning using DSM-5-TR criteria, psychopharmacological
management, crisis intervention, and legal-ethical obligations. The
multiple-choice format tests foundational theory and applied
professional practice, ensuring candidates can prioritize differential
diagnoses, interpret assessment data, select appropriate
pharmacological and non-pharmacological interventions, and
,develop comprehensive, patient-centered treatment plans across
the lifespan.
SECTION ONE: QUESTIONS 1–200
1. A 28-year-old female presents with a 3-week history of
depressed mood, anhedonia, insomnia, and feelings of
worthlessness. She denies suicidal ideation. Which DSM-5-TR
diagnosis is most appropriate?
A. Persistent depressive disorder
B. Major depressive disorder, single episode
C. Bipolar II disorder, depressed phase
D. Adjustment disorder with depressed mood
🟢B
🔴 RATIONALE: The patient meets the criteria for a major
depressive episode (five or more symptoms for at least 2 weeks),
including depressed mood and anhedonia. The duration of 3
weeks exceeds the 2-week minimum. Persistent depressive
disorder requires 2 years of symptoms, and bipolar II requires a
history of hypomania.
2. A 35-year-old male with schizophrenia has been on risperidone
for 3 years and now reports involuntary tongue movements and
lip smacking. Which condition should the PMHNP suspect?
A. Acute dystonia
B. Akathisia
,C. Tardive dyskinesia
D. Parkinsonism
🟢C
🔴 RATIONALE: Tardive dyskinesia is characterized by involuntary,
repetitive movements, particularly of the tongue, lips, and face,
and typically develops after long-term antipsychotic use. Acute
dystonia occurs early and involves muscle spasms.
3. Which laboratory test must be monitored weekly during the
first 6 months of clozapine therapy?
A. Serum lithium level
B. Absolute neutrophil count (ANC)
C. Liver function tests
D. Serum creatinine
🟢B
🔴 RATIONALE: Clozapine carries a risk of agranulocytosis, and
the ANC must be monitored weekly for the first 6 months, then
every 2 weeks for 6 months, and monthly thereafter per REMS
requirements.
4. A 42-year-old female on lithium for bipolar I disorder presents
with coarse tremor, ataxia, vomiting, and confusion. Her lithium
level is 2.4 mEq/L. What is the priority intervention?
A. Administer the next scheduled lithium dose
B. Hold lithium and notify the provider immediately
, C. Encourage increased fluid intake
D. Administer a PRN benzodiazepine
🟢B
🔴 RATIONALE: A lithium level of 2.4 mEq/L is in the toxic range
(therapeutic: 0.6–1.2 mEq/L). Coarse tremor, ataxia, vomiting, and
confusion indicate moderate to severe toxicity. Lithium must be
held immediately, and the provider notified.
5. A 24-year-old male with bipolar I disorder is started on valproic
acid. Which laboratory values should be monitored?
A. CBC, liver function tests, and serum valproate level
B. INR and aPTT
C. Thyroid function and lipid panel
D. Serum creatinine and BUN only
🟢A
🔴 RATIONALE: Valproic acid can cause hepatotoxicity,
thrombocytopenia, and pancreatitis. Monitoring includes CBC,
liver function tests, and serum valproate levels (therapeutic: 50–
125 mcg/mL).
6. A patient taking fluoxetine reports agitation, diaphoresis,
hyperreflexia, and muscle rigidity. Which condition should the
PMHNP suspect?
A. Neuroleptic malignant syndrome
B. Serotonin syndrome
