Answers & Detailed Rationales
Question 1: A client with borderline personality disorder exhibits manipulative
behaviors. Which nursing intervention is most appropriate to address this
behavior?
A. Confront the client immediately when manipulative behavior is observed.
B. Ignore the manipulative behavior to avoid reinforcing it with attention.
C. Establish consistent limits and consequences for manipulative behaviors.
D. Allow the behavior to ensure a therapeutic alliance is maintained.
CORRECT ANSWER: C. Establish consistent limits and consequences for
manipulative behaviors.
Rationale: Clients with borderline personality disorder often test boundaries. Consistent
limit-setting with clear consequences provides structure and security, reducing anxiety
and manipulative attempts. Confrontation (A) can escalate behavior; ignoring (B) may be
perceived as acceptance; allowing the behavior (D) undermines therapeutic boundaries
and reinforces maladaptive patterns.
Question 2: A client experiencing alcohol withdrawal is prescribed
chlordiazepoxide. What is the primary purpose of this medication?
A. To prevent Wernicke-Korsakoff syndrome.
B. To manage hypertensive crisis.
C. To reduce the risk of seizures and delirium tremens.
D. To decrease cravings for alcohol.
CORRECT ANSWER: C. To reduce the risk of seizures and delirium tremens.
Rationale: Chlordiazepoxide, a benzodiazepine, is used in alcohol withdrawal for its
cross-tolerance with alcohol, preventing central nervous system hyperactivity that leads
to seizures and delirium tremens. It does not prevent Wernicke-Korsakoff syndrome (A)
(thiamine does), manage hypertensive crisis (B), or primarily decrease cravings (D)
(medications like naltrexone do).
Question 3: A client with major depressive disorder begins taking phenelzine.
Which dietary instruction is most critical for the nurse to provide?
,A. Avoid foods high in tyramine.
B. Increase intake of high-fiber foods.
C. Limit fluid intake to 1.5 liters per day.
D. Consume a high-protein diet.
CORRECT ANSWER: A. Avoid foods high in tyramine.
Rationale: Phenelzine is a monoamine oxidase inhibitor (MAOI). Tyramine-rich foods
(aged cheeses, cured meats, fermented products) can cause a hypertensive crisis due to
MAO inhibition. Fiber (B), fluid restriction (C), or high-protein diets (D) are not specific
safety concerns for this medication.
Question 4: A client with schizophrenia is experiencing auditory
hallucinations. What is the most therapeutic response by the nurse?
A. "The voices are not real, so try to ignore them."
B. "I understand the voices are frightening to you."
C. "What are the voices telling you to do?"
D. "You need to focus on reality, not the voices."
CORRECT ANSWER: B. "I understand the voices are frightening to you."
Rationale: Acknowledging the client's feelings without validating the hallucination (B) is
therapeutic. Telling the client to ignore the voices (A) denies the experience; asking for
content (C) can reinforce the hallucination; focusing on reality (D) is dismissive and non-
therapeutic.
Question 5: A client with bipolar disorder is prescribed lithium. Which
laboratory value should the nurse monitor most closely?
A. Serum sodium.
B. Serum potassium.
C. Serum lithium.
D. Serum glucose.
CORRECT ANSWER: C. Serum lithium.
Rationale: Lithium has a narrow therapeutic window. Serum lithium levels must be
monitored to prevent toxicity. Sodium (A) affects lithium excretion, but lithium level
itself (C) is the direct measure of safety and efficacy. Potassium (B) and glucose (D) are
not specific to lithium therapy.
Question 6: A client with post-traumatic stress disorder (PTSD) reports
recurrent nightmares. Which symptom cluster does this represent?
,A. Hyperarousal.
B. Avoidance.
C. Intrusion.
D. Negative alterations in cognition and mood.
CORRECT ANSWER: C. Intrusion.
Rationale: Recurrent nightmares are a re-experiencing (intrusion) symptom (C).
Hyperarousal (A) includes hypervigilance; avoidance (B) includes avoiding reminders;
negative alterations (D) include distorted blame or anhedonia.
Question 7: A client is admitted with a diagnosis of antisocial personality
disorder. Which behavior is the nurse most likely to observe?
A. Extreme dependence and difficulty making decisions.
B. Social inhibition and fear of criticism.
C. Lack of remorse for harming others.
D. Submissive and clinging behavior.
CORRECT ANSWER: C. Lack of remorse for harming others.
Rationale: Antisocial personality disorder is characterized by a pervasive disregard for
others' rights, including lack of remorse (C). Dependence (A) is characteristic of
dependent personality; social inhibition (B) of avoidant; submissive behavior (D) of
dependent or histrionic.
Question 8: A client with generalized anxiety disorder is prescribed buspirone.
The nurse should instruct the client that this medication:
A. Provides immediate relief of anxiety symptoms.
B. Can cause physical dependence if stopped abruptly.
C. May take several weeks to reach full therapeutic effect.
D. Should be taken on an empty stomach.
CORRECT ANSWER: C. May take several weeks to reach full therapeutic effect.
Rationale: Buspirone is a non-benzodiazepine anxiolytic with a delayed onset of action,
often taking 2-4 weeks for full effect (C). It does not provide immediate relief (A); it has
low abuse potential and does not cause significant dependence (B); food increases
absorption, so it can be taken with or without food (D).
Question 9: A client with dementia is pacing and agitated. Which initial
nursing action is most appropriate?
A. Administer a PRN sedative.
B. Place the client in seclusion.
, C. Offer a high-calorie snack.
D. Redirect to a safe, calm activity.
CORRECT ANSWER: D. Redirect to a safe, calm activity.
Rationale: Redirection to a calm activity (D) is the least restrictive, safest initial
intervention for agitation. Sedatives (A) should not be first-line; seclusion (B) is
restrictive and used only when safety is compromised; offering a snack (C) may be
appropriate but does not address agitation directly.
Question 10: A client with anorexia nervosa refuses to eat, stating, "I'm too
fat." Which nursing response is most therapeutic?
A. "You are not fat; you are dangerously underweight."
B. "Let's discuss your feelings about your body image."
C. "If you don't eat, you will need a feeding tube."
D. "You look fine; please eat your meal."
CORRECT ANSWER: B. "Let's discuss your feelings about your body image."
Rationale: Exploring feelings about body image (B) is therapeutic and opens
communication. Challenging the client's perception (A) can increase resistance;
threatening (C) may lead to power struggles; reassuring (D) dismisses the client's
feelings.
Question 11: A client with obsessive-compulsive disorder (OCD) performs
handwashing rituals for hours each day. The nurse understands this behavior
is primarily aimed at:
A. Reducing anxiety.
B. Gaining attention.
C. Manipulating staff.
D. Avoiding social interaction.
CORRECT ANSWER: A. Reducing anxiety.
Rationale: In OCD, compulsions are repetitive behaviors performed to neutralize distress
or prevent a feared event, primarily aimed at reducing anxiety (A). They are not
primarily for attention (B), manipulation (C), or social avoidance (D), though social
avoidance may be a secondary consequence.
Question 12: A client is experiencing a panic attack. Which symptom is most
consistent with this diagnosis?
A. Feelings of detachment from self.
B. Persistent worry about multiple events.
