Section 1: Foundations of Mental Health Nursing (Questions 1-19)
1 A nurse is providing care to a patient with a history of trauma who exhibits hypervigilance and emotional
numbing. The patient states, 'I don't want to talk about it. You wouldn't understand.' Which therapeutic response
best demonstrates the principle of fostering insight?
A) "You're right, I don't know exactly how you feel, but I'd like to understand."
B) "Talking about it is the only way to get better."
C) "It's okay not to talk now. When you're ready, I'll be here."
D) "Why do you think you feel that way?"
Answer: A
Rationale: Option A validates the patient's feelings while inviting dialogue without pressure, aligning with Peplau's
interpersonal theory where the nurse uses empathy to build trust and promote insight. Option B is directive and
dismissive; option C, though supportive, does not actively foster insight; option D is a 'why' question that may feel
interrogative.
2 A nursing student is studying the biological basis of mental illness. Which statement accurately reflects current
understanding of the dopamine hypothesis in schizophrenia?
A) Excess dopamine in the mesocortical pathway causes negative symptoms.
B) Hypoactivity of dopamine in the mesolimbic pathway is linked to positive symptoms.
C) Dopamine dysregulation involves both hyper- and hypoactivity across different pathways.
D) All antipsychotics work by blocking D2 receptors in the striatum exclusively.
Answer: C
Rationale: The current dopamine hypothesis posits that positive symptoms are associated with hyperdopaminergia
in the mesolimbic pathway, while negative and cognitive symptoms are linked to hypodopaminergia in the
mesocortical pathway. Option A reverses the pathways; option B is incorrect as positive symptoms are linked to
hyperactivity; option D is false because atypical antipsychotics also affect serotonin receptors.
, 3 In the context of psychiatric nursing, which scenario best exemplifies the ethical principle of nonmaleficence?
A) A nurse respects a patient's decision to refuse electroconvulsive therapy after full disclosure of risks.
B) A nurse administers a PRN sedative to a manic patient to prevent physical exhaustion.
C) A nurse advocates for a patient's right to have visitors despite unit restrictions.
D) A nurse documents a patient's threats to self-harm and initiates suicide precautions.
Answer: B
Rationale: Nonmaleficence means 'do no harm.' Administering a sedative to prevent exhaustion from mania
prevents potential harm (e.g., cardiac collapse). Option A is autonomy; option C is fidelity/advocacy; option D is
beneficence and duty to protect.
4 A nurse is conducting a mental status exam on a patient with major depressive disorder. The patient's speech is
slow, with long pauses, and content focuses on worthlessness. Which aspect of the MSE is primarily being
assessed?
A) Form of thought
B) Content of thought
C) Affect
D) Cognition
Answer: B
Rationale: Content of thought refers to what the patient says, including themes like worthlessness, guilt, or
delusions. Form of thought (A) is the structure (e.g., circumstantiality). Affect (C) is the observable emotional
expression. Cognition (D) includes orientation, memory, etc.
5 Which of the following represents a key difference between the DSM-5-TR and previous editions regarding the
diagnosis of posttraumatic stress disorder?
A) PTSD is now classified under 'Trauma- and Stressor-Related Disorders' instead of 'Anxiety Disorders.'
B) The criterion requiring a subjective response of 'fear, helplessness, or horror' has been removed.
C) The symptom cluster now includes negative alterations in cognition and mood as a separate criterion.
D) Acute stress disorder is no longer a distinct diagnosis.
Answer: B
Rationale: The DSM-5 removed the subjective response criterion (A2) that required fear/helplessness/horror, as it
lacked specificity. Option A is true but was a change in DSM-5, not DSM-5-TR. Option C was also introduced in
DSM-5. Option D is false; acute stress disorder remains.
6 A nursing student observes a preceptor using silence during a therapy session. The student later asks why.
Which rationale best supports the therapeutic use of silence?
A) Silence allows the nurse to formulate the next question.
B) Silence encourages the patient to reflect and take the lead in the conversation.
C) Silence reduces the patient's anxiety by providing a break from emotional topics.
D) Silence is used when the patient is being manipulative.
Answer: B
Rationale: Therapeutic silence gives the patient time to organize thoughts, feel understood, and explore feelings at
their own pace. Option A is a nontherapeutic use (nurse-centered). Option C may be partially true but the primary
purpose is to facilitate patient exploration. Option D is judgmental and nontherapeutic.
7 A nurse is caring for a patient with borderline personality disorder who has a history of self-harm. The patient
says, 'You're the only one who really cares. The other nurses are terrible.' Which response demonstrates the
nurse's understanding of the patient's defense mechanism?
,A) "I'm glad you feel that way, but let's focus on your treatment goals."
B) "It sounds like you're splitting the staff into good and bad."
C) "Why do you think the other nurses are terrible?"
D) "I'll make sure to communicate your concerns to the team."
Answer: B
Rationale: Splitting is a primitive defense mechanism common in BPD where the patient idealizes one person and
devalues others. Option B directly labels the behavior in a nonjudgmental way, promoting insight. Option A
reinforces idealization; option C invites further splitting; option D may be appropriate but does not address the
defense mechanism.
8 A patient with obsessive-compulsive disorder spends hours checking locks and stoves. The nurse implements
response prevention. Which statement best describes the rationale for this intervention?
A) It prevents the patient from engaging in compulsive behaviors, leading to extinction of the anxiety response.
B) It provides a safe environment while the patient works through the underlying trauma.
C) It reduces the patient's need for medication by substituting a healthier behavior.
D) It helps the patient understand the irrationality of their thoughts through logical discussion.
Answer: A
Rationale: Response prevention is a behavioral technique where the patient is prevented from performing the
compulsion, allowing the anxiety to decrease naturally (habituation/extinction). Option B is more relevant to
PTSD; option C is not the primary rationale; option D describes cognitive restructuring, not response prevention.
9 A nurse is teaching a patient about the mechanism of action of selective serotonin reuptake inhibitors. Which
statement by the patient indicates a correct understanding?
A) "These medications increase the amount of serotonin available in my brain by blocking its reuptake."
B) "They work by increasing the production of serotonin in the presynaptic neuron."
C) "They block the breakdown of serotonin by monoamine oxidase."
D) "They directly activate serotonin receptors on the postsynaptic neuron."
Answer: A
Rationale: SSRIs selectively inhibit the serotonin transporter, preventing reuptake into the presynaptic neuron,
thereby increasing synaptic serotonin. Option B describes increased synthesis, which is not the mechanism. Option
C is the action of MAOIs. Option D describes a direct agonist, not an SSRI.
10 In the context of Peplau's Interpersonal Relations Theory, which phase is characterized by the client's
exploration of feelings and the nurse's role as a resource person, leading to the resolution of the interpersonal
problem?
A) Orientation phase
B) Identification phase
C) Exploitation phase
D) Resolution phase
Answer: C
Rationale: In Peplau's theory, the exploitation phase involves the client actively using the nurse's resources and
exploring feelings, leading to problem resolution. The orientation phase focuses on building trust, identification
involves the client identifying with the nurse, and resolution marks the termination of the therapeutic relationship.
11 A psychiatric-mental health nurse is applying the Recovery Model in a community setting. Which intervention
best reflects the core principle of self-determination?
A) Developing a structured daily schedule for the client
, B) Encouraging the client to attend a peer support group
C) Allowing the client to choose their own treatment goals
D) Administering prescribed medications on schedule
Answer: C
Rationale: The Recovery Model emphasizes self-determination, where clients are empowered to make their own
decisions regarding treatment goals. Option A reflects a paternalistic approach, B is supportive but not directly
about self-determination, and D is a nursing task that does not involve client choice.
12 A nurse is conducting a mental status exam (MSE) on a client. The client's speech is rapid, pressured, and
difficult to interrupt. Which term should the nurse use to document this finding?
A) Circumstantiality
B) Tangentiality
C) Flight of ideas
D) Perseveration
Answer: C
Rationale: Flight of ideas is characterized by rapid, pressured speech with abrupt topic shifts, often seen in mania.
Circumstantiality involves unnecessary detail but eventually reaches the point, tangentiality never returns to the
original topic, and perseveration is repetition of words or ideas.
13 In the context of therapeutic communication, which technique is most appropriate when a client states, 'I feel
like nobody cares about me'?
A) Offering a reassurance: 'I care about you.'
B) Using silence and maintaining eye contact
C) Reflecting: 'You feel that nobody cares?'
D) Advising: 'You should talk to your family.'
Answer: C
Rationale: Reflection encourages the client to explore feelings further without imposing the nurse's own thoughts.
Reassurance (A) can invalidate feelings, silence (B) may be appropriate but less directly therapeutic in this context,
and advising (D) undermines client autonomy.
14 A nurse is assessing a client for potential risk of suicide. Which factor is most strongly associated with
imminent risk?
A) History of previous suicide attempts
B) Expressing feelings of hopelessness
C) Having a specific plan and means
D) Social isolation
Answer: C
Rationale: A specific plan and means indicate high lethality and imminent risk, requiring immediate intervention.
Previous attempts (A) and hopelessness (B) are risk factors but not as immediate, and social isolation (D) is a
chronic risk factor.
15 Which ethical principle is primarily challenged when a nurse administers a medication against a client's will
under a court order?
A) Beneficence
B) Nonmaleficence
C) Autonomy
D) Justice
