Question 1: A client with borderline personality disorder exhibits manipulative
behaviors. Which nursing intervention is most appropriate to address this
behavior?
A. Allow the client to express feelings without limits to build trust.
B. Ignore the manipulative behaviors to avoid reinforcing them.
C. Enforce unit rules and consequences consistently for all clients.
D. Restrict the client's privileges as punishment for the behavior.
CORRECT ANSWER: C. Enforce unit rules and consequences consistently for
all clients.
Rationale: Clients with borderline personality disorder often test limits and engage in
manipulative behaviors. Consistent enforcement of unit rules and consequences
provides a structured, predictable environment, which is therapeutic and reduces
anxiety. This approach is non-punitive and focuses on accountability. Ignoring behaviors
(B) can escalate them, while punishment (D) is not therapeutic, and allowing all
expressions without limits (A) is not safe or appropriate.
Question 2: A nurse is assessing a client with schizophrenia who has been
taking haloperidol for several years. The client exhibits involuntary, repetitive
movements of the tongue and lips. The nurse should recognize this as which
extrapyramidal symptom?
A. Dystonia
B. Akathisia
C. Tardive dyskinesia
D. Parkinsonism
CORRECT ANSWER: C. Tardive dyskinesia
Rationale: Tardive dyskinesia is a late-onset, irreversible extrapyramidal symptom
characterized by involuntary, repetitive movements of the face, tongue, and mouth (e.g.,
protrusion of the tongue, lip-smacking). It is associated with long-term use of typical
antipsychotics like haloperidol. Dystonia (A) is an acute muscle spasm, akathisia (B) is
motor restlessness, and parkinsonism (D) includes rigidity and tremor.
,Question 3: A client with major depressive disorder is prescribed phenelzine.
Which dietary instruction is most critical for the nurse to include in the
teaching plan?
A. Increase intake of foods high in tyramine.
B. Avoid foods containing tyramine such as aged cheese and cured meats.
C. Restrict fluid intake to prevent water intoxication.
D. Increase dietary fiber to prevent constipation.
CORRECT ANSWER: B. Avoid foods containing tyramine such as aged cheese
and cured meats.
Rationale: Phenelzine is a monoamine oxidase inhibitor (MAOI). Concurrent use with
foods high in tyramine can precipitate a hypertensive crisis, a life-threatening
emergency. Clients must strictly avoid tyramine-rich foods like aged cheeses, cured
meats, and fermented products. Increasing tyramine (A) is dangerous; fluid and fiber
instructions (C, D) are not specific to MAOI safety.
Question 4: A nurse is preparing to administer a benzodiazepine to a client
with generalized anxiety disorder. Which of the following is a primary
mechanism of action for this class of medications?
A. Blocking dopamine receptors in the mesolimbic pathway.
B. Increasing the availability of serotonin in the synaptic cleft.
C. Potentiating the effects of gamma-aminobutyric acid (GABA).
D. Inhibiting the reuptake of norepinephrine.
CORRECT ANSWER: C. Potentiating the effects of gamma-aminobutyric acid
(GABA).
Rationale: Benzodiazepines enhance the inhibitory neurotransmitter GABA by binding to
a specific site on the GABA-A receptor complex. This increases the frequency of
chloride channel opening, leading to a calming effect on the central nervous system.
Blocking dopamine (A) is typical of antipsychotics; increasing serotonin (B) is typical of
SSRIs; and inhibiting norepinephrine reuptake (D) is typical of SNRIs or TCAs.
Question 5: A client with post-traumatic stress disorder (PTSD) reports
recurrent nightmares and intrusive thoughts. Which finding is a common
physiological manifestation of this disorder?
A. Bradycardia and hypotension
B. Decreased muscle tension and relaxation
C. Hypervigilance and exaggerated startle response
D. Increased need for sleep and rest
CORRECT ANSWER: C. Hypervigilance and exaggerated startle response
,Rationale: PTSD is characterized by a dysregulated stress response. Hyperarousal
symptoms are common and include hypervigilance, an exaggerated startle response,
difficulty sleeping, and irritability. These are signs of a sustained sympathetic nervous
system response, not bradycardia (A) or hypotension (A), decreased tension (B), or
increased need for rest (D).
Question 6: A client is admitted involuntarily to a psychiatric unit. The client
demands to leave against medical advice. Which action should the nurse take?
A. Allow the client to leave after signing a release form.
B. Place the client in seclusion until they agree to stay.
C. Inform the client that they are unable to leave due to the court order.
D. Call the client's family to convince them to stay.
CORRECT ANSWER: C. Inform the client that they are unable to leave due to
the court order.
Rationale: Involuntary admission means the client is legally mandated to remain in the
facility for treatment, often due to being a danger to self or others. They do not have the
right to leave at will. The nurse should inform the client of their legal status calmly.
Allowing them to leave (A) is illegal; seclusion (B) is not appropriate for this request and
requires specific criteria; and calling the family (D) does not address the legal issue.
Question 7: Which defense mechanism is being used when a client with
alcohol use disorder states, "I only drink to socialize and my drinking is not a
problem," despite being arrested for a DUI?
A. Projection
B. Rationalization
C. Denial
D. Displacement
CORRECT ANSWER: C. Denial
Rationale: Denial involves refusing to acknowledge the reality of a situation that is
anxiety-provoking. The client is denying the severity of their drinking problem and its
consequences. Rationalization (B) involves using false logic to justify behavior. Projection
(A) is attributing one's own feelings to another, and displacement (D) is transferring
emotions from one object to another.
Question 8: A nurse is performing a mental status examination. Which
statement is true regarding the assessment of a client's thought process?
A. Thought process refers to the content of what the client is saying.
B. A normal thought process is characterized by loose associations.
, C. Thought process is assessed by observing the client's mood.
D. Thought process describes the flow and organization of ideas.
CORRECT ANSWER: D. Thought process describes the flow and organization of
ideas.
Rationale: Thought process is the manner in which a person thinks, referring to the flow,
coherence, and organization of thoughts. Thought content (A) is the subject matter.
Loose associations (B) are an abnormal thought process. Mood (C) is the client's
pervasive emotional state, distinct from thought process.
Question 9: A client with bipolar disorder experiencing a manic episode is
pacing and has not eaten for 12 hours. Which is the priority nursing
intervention?
A. Ask security to restrain the client.
B. Provide finger foods the client can eat while walking.
C. Administer a sedative intramuscularly.
D. Verbally remind the client to sit down and eat.
CORRECT ANSWER: B. Provide finger foods the client can eat while walking.
Rationale: The client's hyperactive state prevents them from sitting for meals. Providing
high-calorie, high-protein finger foods that can be eaten on the move is a practical
intervention to meet their nutritional needs. Restraint (A) is a last resort for safety, not
for eating. Sedation (C) requires a prescription and isn't the first step. Verbal reminders
(D) are unlikely to be effective in an acute manic state.
Question 10: During a group therapy session, a client with antisocial
personality disorder dominates the discussion and belittles other members.
The nurse leader should initially intervene by:
A. Asking the client to leave the group session.
B. Ignoring the behavior to avoid giving it attention.
C. Firmly redirecting the client and setting limits on their behavior.
D. Allowing the group to handle the situation.
CORRECT ANSWER: C. Firmly redirecting the client and setting limits on their
behavior.
Rationale: The nurse leader must maintain a safe environment. The most appropriate
initial action is to redirect the client's behavior and set clear, firm limits on their
dominance and belittling remarks. This protects other group members and models
appropriate boundaries. Asking the client to leave (A) may be necessary if they don't
comply, but it is not the first step. Ignoring (B) or allowing the group to handle it (D) may
endanger the group's therapeutic environment.
