Examination Overview: This comprehensive 110-question examination has been developed in alignment with Galen
College of Nursing NUR 256 Concepts of Mental Health Nursing Exam 4 course objectives, reflecting the 2026-2027
mental health nursing curriculum standards and current DSM-5-TR criteria. The exam covers nine content domains: (1)
Personality Disorders; (2) Eating Disorders; (3) Substance Use and Addictive Disorders; (4) Neurocognitive Disorders; (5)
Somatic Symptom and Related Disorders; (6) Dissociative and Trauma-Related Disorders; (7) Child and Adolescent
Psychiatric Disorders; (8) Crisis, Suicide, and Aggression Management; and (9) Psychiatric Rehabilitation, Recovery, and
Community Care. Each question includes a verified answer with a detailed rationale incorporating diagnostic criteria,
therapeutic communication principles, safety considerations, psychopharmacology, evidence-based interventions, and
mental health nursing clinical judgment at the Galen NUR 256 standard. The cognitive distribution includes approximately
30% recall, 50% application, and 20% analysis questions. Approximately 80% of items are scenario-based clinical vignettes
requiring therapeutic communication, safety prioritization, and clinical decision-making, and 20% are direct recall of
diagnostic criteria, medications, and nursing interventions. This guide serves as both a comprehensive study resource and a
self-assessment tool for the NUR 256 Exam 4 content.
Section 1: Personality Disorders (Cluster A, B, C, Borderline, Antisocial, & Nursing
Interventions)
Q1: A 32-year-old client is admitted to the psychiatric unit with a diagnosis of borderline personality disorder.
The client tells the primary nurse, "You are the only one who understands me. The other nurses are rude and
do not care about me." Which defense mechanism is the client primarily demonstrating?
A. Projection
B. Splitting [CORRECT]
C. Denial
D. Displacement
Correct Answer: B
Rationale: Splitting is a primitive defense mechanism in which the client views people as all good or all-bad, often pitting staff
against each other to manipulate the environment. This is a hallmark feature of borderline personality disorder. Projection (A)
attributes one's own thoughts to others. Denial (C) refuses to accept reality. Displacement (D) redirects emotions to a safer target.
NUR 256 strategy: all-good/all-bad shifts with intense reactions toward staff = splitting; requires team consistency.
Q2: A client with borderline personality disorder has superficially lacerated her wrists after being told she
could not have a second snack. The nurse understands that this behavior most likely serves which primary
function?
A. To manipulate staff into giving her the snack

,NUR 256 Exam 4 - Concepts of Mental Health Nursing (2026/2027) Page 2
B. To relieve intolerable emotional pain and feel a sense of control [CORRECT]
C. To seek attention from peers
D. To genuinely attempt suicide
Correct Answer: B
Rationale: In BPD, self-injury typically functions to relieve intolerable affect, reduce dissociation, and provide a sense of control
or feeling "real." While not primarily a suicide attempt, clients with BPD do have elevated suicide risk and all self-harm requires
careful assessment. NUR 256 strategy: BPD self-harm = affect regulation, not attention-seeking; treat the underlying emotion and
ensure safety.
Q3: A 28-year-old client on the psychiatric unit consistently violates unit rules, demands special treatment, and
intimidates other clients. He has a diagnosis of antisocial personality disorder. Which nursing intervention is
most appropriate?
A. Grant special privileges to maintain a calm environment
B. Enforce unit rules consistently with clear limits while avoiding power struggles and ensuring safety
[CORRECT]
C. Engage in long-term insight-oriented psychotherapy
D. Discharge the client for noncompliance
Correct Answer: B
Rationale: Clients with antisocial personality disorder respond best to firm, consistent limit-setting in a structured environment
with clear consequences, while avoiding power struggles and ensuring safety. Special privileges (A) reinforce manipulation.
Long-term insight therapy (C) is generally ineffective for ASPD. Discharge (D) is not the nurse's decision. NUR 256 strategy:
ASPD = firm, consistent limits, no power struggles, safety first.
Q4: A 45-year-old client presents with a lifelong pattern of emotional detachment, preference for solitary
activities, indifference to social relationships, and restricted emotional expression. He has no close friends and
is content with this lifestyle. Which personality disorder is most likely?
A. Schizoid personality disorder [CORRECT]
B. Schizotypal personality disorder
C. Avoidant personality disorder
D. Paranoid personality disorder
Correct Answer: A
Rationale: Schizoid personality disorder (Cluster A) is characterized by emotional detachment, preference for solitary activities,
indifference to social relationships, and restricted emotional expression. Schizotypal (B) includes odd beliefs or magical thinking.
Avoidant (C) involves hypersensitivity to criticism and desire for relationships. Paranoid (D) involves distrust. NUR 256 strategy:
detached, solitary, indifferent = schizoid; eccentric, odd beliefs = schizotypal.
Q5: A 38-year-old client presents with a long-standing pattern of distrust and suspicion of others, interpreting
others' motives as malicious. He holds grudges and doubts the loyalty of friends. Which personality disorder is
most likely?
A. Paranoid personality disorder [CORRECT]
Galen College of Nursing | Complete Guide with Verified Answers | 100% Correct
,NUR 256 Exam 4 - Concepts of Mental Health Nursing (2026/2027) Page 3
B. Schizoid personality disorder
C. Borderline personality disorder
D. Histrionic personality disorder
Correct Answer: A
Rationale: Paranoid personality disorder (Cluster A) is characterized by pervasive distrust and suspicion of others, interpreting
motives as malevolent, holding grudges, and doubting loyalty. Schizoid (B) is detached. Borderline (C) involves instability and
self-harm. Histrionic (D) involves attention-seeking. NUR 256 strategy: paranoid = distrust + suspicion + grudges; approach with
straightforward, non-intrusive communication.
Q6: A 25-year-old client presents with a lifelong pattern of social inhibition, feelings of inadequacy, and
hypersensitivity to negative evaluation. He avoids occupational activities involving interpersonal contact
because he fears criticism. Which personality disorder is most likely?
A. Borderline personality disorder
B. Avoidant personality disorder [CORRECT]
C. Schizoid personality disorder
D. Narcissistic personality disorder
Correct Answer: B
Rationale: Avoidant personality disorder (Cluster C) is characterized by social inhibition, feelings of inadequacy, and
hypersensitivity to negative evaluation. Unlike schizoid, the client desires relationships but fears rejection. Borderline (A)
involves instability. Schizoid (C) is indifferent to relationships. Narcissistic (D) involves grandiosity. NUR 256 strategy: avoidant
= desires relationships but fears rejection; gradual exposure with validation.
Q7: A 30-year-old client has difficulty making everyday decisions without reassurance from others, needs
others to assume responsibility for most major areas of life, and fears being left to care for herself. Which
personality disorder is most likely?
A. Avoidant personality disorder
B. Dependent personality disorder [CORRECT]
C. Obsessive-compulsive personality disorder
D. Histrionic personality disorder
Correct Answer: B
Rationale: Dependent personality disorder (Cluster C) involves pervasive reliance on others for decision-making, fear of being
unable to care for oneself, and urgent seeking of new relationships when one ends. Avoidant (A) fears criticism. OCPD (C)
involves perfectionism and control. Histrionic (D) involves attention-seeking. NUR 256 strategy: dependent = relies on others for
decisions; encourage small independent choices.
Q8: A 40-year-old client presents with preoccupation with orderliness, perfectionism, and mental and
interpersonal control, at the expense of flexibility, openness, and efficiency. He is rigid and stubborn. Which
personality disorder is most likely?
A. Obsessive-compulsive personality disorder (OCPD) [CORRECT]
B. Obsessive-compulsive disorder (OCD)
Galen College of Nursing | Complete Guide with Verified Answers | 100% Correct
, NUR 256 Exam 4 - Concepts of Mental Health Nursing (2026/2027) Page 4
C. Narcissistic personality disorder
D. Avoidant personality disorder
Correct Answer: A
Rationale: OCPD (Cluster C) is characterized by preoccupation with orderliness, perfectionism, and control at the expense of
flexibility. Unlike OCD (B), the behaviors are ego-syntonic (the client does not see them as a problem). Narcissistic (C) involves
grandiosity. Avoidant (D) involves hypersensitivity to criticism. NUR 256 strategy: OCPD = ego-syntonic perfectionism and
control; OCD = ego-dystonic obsessions and compulsions.
Q9: A 35-year-old client presents with a pattern of grandiosity, need for admiration, and lack of empathy. He is
preoccupied with fantasies of unlimited success and believes he is special. Which personality disorder is most
likely?
A. Histrionic personality disorder
B. Narcissistic personality disorder [CORRECT]
C. Antisocial personality disorder
D. Borderline personality disorder
Correct Answer: B
Rationale: Narcissistic personality disorder (Cluster B) is characterized by grandiosity, need for admiration, and lack of empathy.
Histrionic (A) involves excessive emotionality and attention-seeking. Antisocial (C) involves disregard for others' rights.
Borderline (D) involves instability. NUR 256 strategy: narcissistic = grandiosity + need for admiration + lack of empathy;
respectful limit-setting without reinforcing grandiosity.
Q10: A 27-year-old client presents with excessive emotionality, attention-seeking, theatrical speech, and
inappropriate seductive behavior. She is uncomfortable when not the center of attention. Which personality
disorder is most likely?
A. Histrionic personality disorder [CORRECT]
B. Narcissistic personality disorder
C. Borderline personality disorder
D. Avoidant personality disorder
Correct Answer: A
Rationale: Histrionic personality disorder (Cluster B) is characterized by excessive emotionality, attention-seeking, theatrical
speech, and inappropriate seductive behavior. Narcissistic (B) involves grandiosity. Borderline (C) involves instability and
self-harm. Avoidant (D) involves hypersensitivity to criticism. NUR 256 strategy: histrionic = dramatic, attention-seeking,
seductive; maintain professional boundaries.
Q11: A nurse is caring for a client with borderline personality disorder who demands to leave the unit and
states, "If you do not let me go, I will hurt myself." Which nursing action is the priority?
A. Allow the client to leave to prevent self-harm
B. Initiate safety precautions, assess for suicidal ideation, set clear limits, and notify the provider; do not
allow the client to leave if there is a safety concern [CORRECT]
C. Tell the client that threats are not allowed on the unit
