Questions, Answers & Detailed Rationales
Question 1: A client diagnosed with borderline personality disorder frequently
exhibits manipulative behaviors. Which nursing intervention is most
appropriate to address this behavior?
A. Allow the behavior to avoid escalating the client's anxiety.
B. Confront the client immediately and demand they stop the behavior.
C. Ignore the behavior to prevent reinforcing it with attention.
D. Set consistent, firm, and clear limits on the behavior.
CORRECT ANSWER: D. Set consistent, firm, and clear limits on the behavior.
Rationale: Clients with borderline personality disorder often use manipulative behaviors
to meet their needs. The most effective nursing intervention is to set consistent, firm,
and clear limits, which helps the client learn acceptable ways to express needs and
reduces the effectiveness of maladaptive behaviors. Consistency among staff is crucial
to prevent splitting and reinforce structure.
Question 2: A client with schizophrenia is experiencing auditory
hallucinations. Which nursing response is most therapeutic?
A. "I know the voices are real to you, but I don't hear them."
B. "Stop paying attention to those voices; they are not real."
C. "What are the voices telling you to do?"
D. "You need to try harder to ignore the voices."
CORRECT ANSWER: A. "I know the voices are real to you, but I don't hear
them."
Rationale: This response validates the client's experience without reinforcing the
hallucination as reality. It is honest, empathetic, and maintains a therapeutic relationship.
It does not challenge the client or dismiss their perception, which could increase anxiety
or distrust.
,Question 3: A client with major depressive disorder is prescribed phenelzine, a
monoamine oxidase inhibitor (MAOI). Which food item should the nurse
instruct the client to avoid?
A. Apples
B. Roasted chicken
C. Aged cheese
D. Pasta
CORRECT ANSWER: C. Aged cheese
Rationale: Aged cheeses are high in tyramine, which can cause a hypertensive crisis
when consumed with MAOIs. Other foods to avoid include aged meats, fermented
foods, and certain wines. The client must adhere to a low-tyramine diet to prevent a
potentially fatal reaction.
Question 4: A client with generalized anxiety disorder is prescribed buspirone.
Which statement indicates a correct understanding of this medication?
A. "I can take this medication as needed for panic attacks."
B. "This medication will work immediately to relieve my anxiety."
C. "I should take this medication every day, even when I feel fine."
D. "I can stop this medication abruptly if I start feeling better."
CORRECT ANSWER: C. "I should take this medication every day, even when I
feel fine."
Rationale: Buspirone is a non-benzodiazepine anxiolytic that must be taken daily on a
regular schedule, not as needed. It has a delayed onset of action, often taking 2-4 weeks
to achieve therapeutic effects, so it must be taken consistently even when symptoms are
not severe.
Question 5: A nurse is assessing a client with post-traumatic stress disorder
(PTSD). Which symptom is a hallmark of this disorder?
A. Obsessive-compulsive rituals
B. Intrusive flashbacks and nightmares
C. Somatic complaints with no medical cause
D. Grandiose delusions
CORRECT ANSWER: B. Intrusive flashbacks and nightmares
Rationale: Intrusive re-experiencing of the traumatic event through flashbacks,
nightmares, or distressing memories is a hallmark symptom of PTSD. Other core
symptoms include avoidance, negative alterations in cognition and mood, and
hyperarousal.
,Question 6: A client is experiencing alcohol withdrawal. The nurse should
closely monitor the client for which life-threatening complication?
A. Hypoglycemia
B. Seizures and delirium tremens
C. Hypertensive crisis
D. Acute kidney injury
CORRECT ANSWER: B. Seizures and delirium tremens
Rationale: Alcohol withdrawal can progress to severe, life-threatening complications,
including generalized seizures and delirium tremens (DTs), which manifest as severe
confusion, autonomic instability, and hallucinations. Monitoring for these signs is critical
for client safety.
Question 7: A client with obsessive-compulsive disorder (OCD) performs
handwashing rituals for 2 hours daily. What is the primary purpose of this
behavior?
A. To reduce anxiety associated with obsessive thoughts
B. To gain attention from family members
C. To express unconscious hostility
D. To ensure physical cleanliness and prevent infection
CORRECT ANSWER: A. To reduce anxiety associated with obsessive thoughts
Rationale: In OCD, compulsive rituals are performed in response to obsessions
(persistent, intrusive thoughts) to neutralize anxiety or distress. The behavior is a
maladaptive coping mechanism to temporarily reduce anxiety, not primarily for practical
or social reasons.
Question 8: A client is prescribed risperidone for schizophrenia. The nurse
should monitor for which common adverse effect?
A. Weight loss and insomnia
B. Extrapyramidal symptoms and weight gain
C. Hypertension and tachycardia
D. Hyperthyroidism and dry mouth
CORRECT ANSWER: B. Extrapyramidal symptoms and weight gain
Rationale: Risperidone is an atypical antipsychotic associated with significant metabolic
side effects, including weight gain, and extrapyramidal symptoms (EPS) at higher doses,
such as parkinsonism, akathisia, and dystonia. Regular monitoring is essential.
, Question 9: A nurse is establishing a therapeutic relationship with a client who
has a history of severe trauma. Which phase of the relationship is most critical
for building trust?
A. Orientation phase
B. Working phase
C. Termination phase
D. Pre-orientation phase
CORRECT ANSWER: A. Orientation phase
Rationale: The orientation phase is when the nurse and client first meet, set boundaries,
and establish a contract. This is the foundational phase where trust is initiated. Without
trust, the client will not feel safe to engage in the working phase.
Question 10: A client with bipolar disorder is in a manic phase. Which nursing
intervention is most important to ensure the client's physical safety?
A. Provide a structured, quiet environment with minimal stimuli
B. Allow the client to roam freely to expend excess energy
C. Engage the client in competitive group activities to channel energy
D. Encourage the client to make independent decisions about daily activities
CORRECT ANSWER: A. Provide a structured, quiet environment with minimal
stimuli
Rationale: During a manic phase, clients are at high risk for injury due to poor impulse
control, agitation, and exhaustion. A quiet, structured environment with minimal stimuli
helps reduce agitation and prevent harm. This intervention addresses safety as the top
priority.
Question 11: The nurse is caring for a client who has been prescribed lithium.
Which serum lithium level indicates a therapeutic range for maintenance
therapy?
A. 0.4 mEq/L
B. 1.0 mEq/L
C. 1.8 mEq/L
D. 2.2 mEq/L
CORRECT ANSWER: B. 1.0 mEq/L
Rationale: The therapeutic serum lithium level for maintenance therapy is generally
between 0.6 and 1.2 mEq/L. 1.0 mEq/L falls within this range. Levels below 0.6 are
generally subtherapeutic, and levels above 1.5 mEq/L indicate toxicity.
