Psychiatric Mental Health Nurse Practitioner Certification
Exam Version 2 – Advanced Psychiatric Nursing Practice
Questions
1. A 32-year-old female patient presents with a history of mood swings, impulsivity, and
intense, unstable relationships. During the assessment, the PMHNP notes the patient uses
splitting as a defense mechanism. Which psychotherapy is considered the gold standard for
this diagnosis?
A. Cognitive Behavioral Therapy (CBT)
B. Dialectical Behavior Therapy (DBT)
C. Interpersonal Therapy (IPT)
D. Eye Movement Desensitization and Reprocessing (EMDR)
Ans: B
Rationale: Dialectical Behavior Therapy (DBT) was specifically designed by Marsha Linehan to treat
Borderline Personality Disorder (BPD). This therapy focuses on the concepts of mindfulness, distress
tolerance, emotion regulation, and interpersonal effectiveness. Splitting is a common defense mechanism
in BPD where individuals see others as all good or all bad. CBT is effective for many disorders but is not
the primary specialized treatment for BPD’s core personality traits. IPT focuses on role transitions and
grief rather than the complex emotional dysregulation found in BPD. EMDR is primarily used for trauma-
related disorders such as PTSD rather than personality disorders. The PMHNP must recognize that DBT
utilizes both individual therapy and group skills training to achieve stability. Long-term management
involves teaching the patient to integrate contradictory experiences and emotions.
,2. Which lab value is most critical for the PMHNP to monitor before and during treatment
with Clozapine (Clozaril)?
A. Thyroid Stimulating Hormone (TSH)
B. Liver Function Tests (LFTs)
C. Absolute Neutrophil Count (ANC)
D. Serum Creatinine
Ans: C
Rationale: Clozapine carries a high risk for agranulocytosis, which is a life-threatening reduction in the
number of white blood cells. The Absolute Neutrophil Count (ANC) is the specific metric used to monitor
this risk according to the FDA-mandated REMS program. Before starting the medication, a baseline ANC
must be established to ensure the patient is safe to begin treatment. Monitoring continues weekly for the
first six months, then biweekly, and eventually monthly if results remain stable. LFTs are important for
many psychotropics but are not the primary safety concern with Clozapine specifically. TSH monitoring is
typically associated with Lithium therapy rather than antipsychotics like Clozapine. Serum Creatinine is
more relevant for medications cleared renally, such as Lithium, whereas Clozapine is metabolized by the
liver. The PMHNP is responsible for educating the patient on the necessity of regular blood draws to
prevent severe infection.
,3. A patient taking Lithium for Bipolar I Disorder presents with coarse tremors, ataxia, and
confusion. What is the most likely cause of these symptoms?
A. Therapeutic Lithium levels
B. Hyponatremia
C. Lithium toxicity
D. Serotonin Syndrome
Ans: C
Rationale: Lithium has a narrow therapeutic index, meaning the difference between a therapeutic and
toxic dose is small. Coarse tremors, ataxia, slurred speech, and confusion are classic signs of moderate to
severe Lithium toxicity. Therapeutic levels usually range from 0.6 to 1.2 mEq/L, and mild tremors are
common at these levels. Hyponatremia can actually lead to Lithium toxicity because the kidneys reabsorb
Lithium in place of sodium. Serotonin Syndrome involves hyperreflexia and autonomic instability, which
are distinct from the neurological signs of Lithium overdose. If toxicity is suspected, the PMHNP should
immediately order a serum lithium level and advise the patient to stop the medication. Severe toxicity
may require emergency medical intervention including hemodialysis to clear the drug from the system.
Ensuring the patient maintains adequate hydration and consistent salt intake is a vital part of PMHNP
education.
, 4. Which neurotransmitter is primarily targeted by most first-generation antipsychotics
(FGAs)?
A. Serotonin 5-HT2A
B. Dopamine D2
C. GABA
D. Norepinephrine
Ans: B
Rationale: First-generation antipsychotics, also known as typical antipsychotics, act primarily as
antagonists at the Dopamine D2 receptor. This blockade occurs throughout the brain, including the
mesolimbic and nigrostriatal pathways. In the mesolimbic pathway, D2 blockade reduces the positive
symptoms of schizophrenia such as hallucinations. However, blockade in the nigrostriatal pathway leads
to extrapyramidal symptoms (EPS) like tardive dyskinesia. Second-generation antipsychotics also target
Serotonin 5-HT2A receptors, which helps balance dopamine release and reduces EPS risk. GABA is an
inhibitory neurotransmitter targeted more by benzodiazepines than antipsychotics. Norepinephrine is
involved in mood and attention but is not the primary target for treating psychosis in FGAs. The PMHNP
must balance the efficacy of D2 blockade with the potential for metabolic and neurological side effects.
