Introduction
This comprehensive practice examination assesses the knowledge
required for the NR 605 Final Exam at Chamberlain University. It
evaluates advanced psychiatric assessment, DSM-5-TR diagnostic
criteria, psychopharmacology, and management of mental health
disorders across the lifespan. Questions emphasize clinical reasoning,
evidence-based prescribing, and safety. The examination prepares
PMHNP students for the proctored final exam and national certification.
1. A 34-year-old client presents for an initial psychiatric evaluation
reporting persistent low mood, anhedonia, and fatigue for the past 8
weeks. The PMHNP begins the diagnostic process by conducting a
comprehensive mental status examination. Which component of the
mental status examination is most critical to document thoroughly
when differentiating major depressive disorder from bipolar
disorder with a current depressive episode?
A. Detailed history of prior elevated, expansive, or irritable mood
episodes
,B. Orientation to person, place, and time
C. Immediate and delayed recall of three objects
D. Assessment of abstract reasoning using proverb interpretation
Correct answer: A. Detailed history of prior elevated, expansive, or
irritable mood episodes
RATIONALE: A thorough history of prior mood elevation is
essential because bipolar depression can present identically to unipolar
depression. Missing past hypomanic or manic episodes leads to incorrect
diagnosis and potentially harmful antidepressant monotherapy .
2. During a psychiatric evaluation of a 28-year-old client who
reports auditory hallucinations, the PMHNP notes that the client
appears to be responding to internal stimuli and has difficulty
maintaining logical conversation. Which formal thought process
abnormality is most consistent with these observations and is
commonly associated with schizophrenia spectrum disorders?
A. Circumstantiality with eventual return to the original topic
B. Blocking characterized by sudden cessation of speech
C. Tangentiality with derailment and loose associations
D. Perseveration with repetitive return to the same idea
Correct answer: C. Tangentiality with derailment and loose
associations
RATIONALE: Tangentiality with derailment and loose associations
reflects disordered thought form typical of schizophrenia.
Circumstantiality remains goal-directed albeit delayed. Blocking and
perseveration can occur in multiple conditions but are less specifically
linked to the formal thought disorder of psychosis .
,3. A PMHNP is evaluating a 45-year-old client for possible
generalized anxiety disorder. The client reports excessive worry
about multiple domains for more than 6 months, muscle tension,
and sleep disturbance. To confirm the diagnosis using DSM-5-TR
criteria, which additional finding must be present?
A. Worry that is exclusively focused on performance in social situations
B. Symptoms that cause clinically significant distress or functional
impairment
C. A history of panic attacks that occur unexpectedly
D. Obsessive thoughts that the client recognizes as irrational
Correct answer: B. Symptoms that cause clinically significant
distress or functional impairment
RATIONALE: DSM-5-TR requires that the anxiety and worry cause
clinically significant distress or impairment in social, occupational, or
other important areas of functioning. Social-performance focus suggests
social anxiety disorder; unexpected panic attacks point toward panic
disorder; and ego-dystonic obsessions are characteristic of OCD .
4. A 52-year-old client is referred for evaluation of cognitive
complaints. The PMHNP administers the Montreal Cognitive
Assessment (MoCA) as part of the assessment. Which score range
on the MoCA is generally considered indicative of mild cognitive
impairment rather than normal aging or frank dementia?
A. 26-30
B. 10-17
C. 0-9
D. 18-25
Correct answer: D. 18-25
, RATIONALE: Scores of 18-25 on the MoCA are typically
associated with mild cognitive impairment. Scores of 26-30 are
generally considered normal, while scores below 18 raise concern for
more significant cognitive impairment consistent with dementia .
5. When performing a risk assessment for a client who expresses
passive suicidal ideation, the PMHNP must systematically evaluate
protective factors. Which of the following is considered the strongest
protective factor against suicide completion in adults?
A. Strong social support network and reasons for living
B. Presence of a detailed suicide plan with access to means
C. History of previous non-lethal suicide attempts
D. Active substance use disorder with recent relapse
Correct answer: A. Strong social support network and reasons for
living
RATIONALE: A strong social support network and reasons for
living are among the most robust protective factors against suicide.
Presence of a plan and access to means are risk factors. Previous
attempts and active substance use are significant risk factors, not
protective .
6. A 23-year-old graduate student is brought by roommates who
report she has not slept in 4 days, talks "a mile a minute," and spent
her entire $20,000 fellowship check on rare sneakers. She claims she
is "about to revolutionize finance" and has no previous psychiatric
history. Urine tox is negative. Which diagnosis is MOST accurate?
A. Bipolar I disorder, manic episode
B. Bipolar II disorder, hypomanic episode
