WGU D344 PMHNP Objective Assessment (OA) |
Questions and Answers | 2026 Update | 100% Correct.
INTRODUCTION
Mastering the WGU D344: Assessment and Diagnostic Process of
Psychiatric Nurse Practitioner Objective Assessment requires a deep,
integrated understanding of advanced psychiatric evaluations, complex
diagnostic criteria, and critical safety parameters in clinical
psychopharmacology. This comprehensive preparation bank simulates
high-yield board-style scenarios across the lifespan to sharpen your
diagnostic reasoning under pressure. By working through these realistic
clinical cases, you will master vital screening tool thresholds, biological
and neurochemical pathways, and precise pharmacological monitoring
protocols required to excel on your exam.
Question 1
A 28-year-old female presents to the mental health clinic reporting a
history of dramatic mood shifts. She states that two weeks ago, she felt
"on top of the world," required only 2 hours of sleep per night, spent her
entire savings on luxury handbags, and spoke so rapidly that her friends
could not interrupt her. Currently, she reports feeling profoundly
depressed, empty, and suicidal. Her past medical history is unremarkable.
Which of the following is the most likely primary diagnosis according to
,the DSM-5-TR?
A) Bipolar II Disorder
B) Cyclothymic Disorder
C) Major Depressive Disorder
D) Bipolar I Disorder
Verified Answer: D) Bipolar I Disorder
Explanation: Bipolar I Disorder requires the occurrence of at least
one lifetime manic episode. A manic episode is defined as a distinct
period of abnormally and persistently elevated, expansive, or
irritable mood, and abnormally and persistently increased activity
or energy, lasting at least 1 week and present most of the day,
nearly every day. The patient's symptoms (decreased need for
sleep, grandiosity/spending spree, and pressured speech) lasted
two weeks and caused severe functional impairment, meeting full
manic criteria. Bipolar II requires a hypomanic episode (at least 4
days, no marked impairment) and a major depressive episode.
Cyclothymia requires at least 2 years of fluctuating hypomanic and
depressive symptoms that do not meet full criteria. Major
Depressive Disorder cannot be diagnosed if there is a history of a
manic or hypomanic episode.
Question 2
,A 42-year-old male with a long-standing history of treatment-resistant
schizophrenia is brought to the clinic by his case manager. The patient
has failed trials of risperidone and olanzapine. The PMHNP decides to
initiate clozapine. Which of the following absolute neutrophil count (ANC)
values represents the minimum baseline required to safely initiate
clozapine therapy in a general population patient?
A) ≥ 1,000/µL
B) ≥ 1,500/µL
C) ≥ 2,000/µL
D) ≥ 500/µL
Verified Answer: B) ≥ 1,500/µL
Explanation: According to the Clozapine Risk Evaluation and
Mitigation Strategy (REMS) guidelines, the baseline absolute
neutrophil count (ANC) must be greater than or equal to 1,500/µL in
the general population before treatment can be initiated. For
patients with documented Benign Ethnic Neutropenia (BEN), the
baseline threshold is lower, at greater than or equal to 1,000/µL.
Initiating clozapine below these thresholds places the patient at
catastrophic risk for severe neutropenia and fatal agranulocytosis.
Question 3
A 19-year-old college student presents with severe test anxiety, insomnia,
and an pervasive sense of dread. During the interview, she mentions that
, whenever she feels overwhelmed, she consciously forces herself to stop
thinking about her upcoming finals and locks her study materials in a
drawer until the morning of the exam. Which ego defense mechanism is
this patient actively deploying?
A) Repression
B) Suppression
C) Denial
D) Rationalization
Verified Answer: B) Suppression
Explanation: Suppression is a mature ego defense mechanism that
involves the conscious, voluntary decision to delay or push out of
awareness painful thoughts, feelings, or impulses. The key
distinction here is that the patient is making a deliberate, conscious
choice ("consciously forces herself") to set aside her worries.
Repression is an entirely unconscious process where anxiety-
provoking thoughts are automatically buried. Denial is a refusal to
acknowledge external reality altogether. Rationalization involves
creating logical, socially acceptable explanations for unacceptable
behaviors or feelings.
Question 4
A PMHNP evaluates a 35-year-old male who presents with a 7-month
history of auditory hallucinations, persecutory delusions, flat affect, and
