SECTION I: THERAPEUTIC COMMUNICATION & THE NURSE-PATIENT RELATIONSHIP
Q1. A client on the mental health unit is becoming more agitated, shouting at
staff, and pacing in the hallway. Which nursing intervention should the
RN implement FIRST?
A) Administer a PRN dose of haloperidol
B) Place the client in seclusion
C) Approach the client calmly and offer to talk in a quiet area
D) Call for security to restrain the client
Correct Answer: C
Rationale: The least restrictive intervention should be attempted first.
Approaching the client calmly and offering to talk in a quiet area uses
de-escalation techniques. Medications, seclusion, and restraints should
only be used when less restrictive measures have failed or if the client
is an immediate danger to self or others.
Q2. A client tells the nurse, "I don't think I can go on anymore. Everything
is hopeless." What is the nurse's BEST response?
A) "You have so much to live for. Think about your family."
B) "Are you thinking about harming yourself?"
C) "I understand how you feel. I've been there too."
D) "Let's focus on the positive things in your life."
Correct Answer: B
Rationale: The nurse must directly assess for suicidal ideation when a
client expresses hopelessness. Asking directly about suicidal thoughts
,is therapeutic and does not "plant" the idea. This is a safety priority.
Q3. A client with schizophrenia tells the nurse, "The voices are telling me
to hurt myself." What is the priority nursing action?
A) Document the client's statement
B) Place the client on one-to-one observation
C) Administer PRN antipsychotic medication
D) Ask the client what the voices are saying
Correct Answer: D
Rationale: The nurse must first assess the content of the hallucinations
to determine the risk of harm to self or others. Asking "What are the
voices telling you?" provides essential safety information.
Q4. A client is admitted to the mental health unit and reports taking extra
antianxiety medication because "I'm so stressed out." Which
assessment question is most important?
A) "How much medication did you take?"
B) "What is causing you so much stress?"
C) "How long have you been taking this medication?"
D) "Have you ever taken extra medication before?"
Correct Answer: A
Rationale: The priority is to determine the amount of medication taken
to assess for overdose risk. This is a medical emergency requiring
immediate assessment.
Q5. A nurse is caring for a client who is extremely anxious and states she
is worried about the sun coming up the next day. The nurse
recognizes this as:
A) A delusion
B) An obsession
C) A phobia
D) Anticipatory anxiety
Correct Answer: D
Rationale: Anticipatory anxiety involves excessive worry about future
events. The client's fear about the sun coming up reflects anxiety about
facing another day.
Q6. Which therapeutic communication technique is most effective when a client
is exhibiting signs of escalating anger?
A) Using open-ended questions
B) Maintaining a calm, neutral tone of voice
, C) Offering choices to give the client a sense of control
D) All of the above
Correct Answer: D
Rationale: All three techniques are effective de-escalation strategies.
Open-ended questions encourage expression of feelings, a calm tone
prevents escalation, and offering choices empowers the client.
SECTION II: PSYCHIATRIC DISORDERS

fluoxetine (Prozac). The nurse should teach the client that therapeutic
effects may not be seen for:

B) 3-5 days
C) 2-4 weeks
D) 6-8 weeks
Correct Answer: C
Rationale: SSRIs like fluoxetine typically take 2-4 weeks to reach
therapeutic effect. Clients should be educated about this delay to
prevent premature discontinuation.
Q8. A client with bipolar disorder is in the manic phase. Which intervention
is MOST important for the nurse to implement?
A) Encourage participation in group activities
B) Provide a structured environment with frequent rest periods
C) Allow the client to make all decisions about daily activities

Correct Answer: B
Rationale: Clients in the manic phase have high energy and may neglect
basic needs. A structured environment with frequent rest periods helps
prevent exhaustion and provides necessary boundaries.
Q9. A client diagnosed with paranoid schizophrenia tells the nurse,
"The FBI is following me and has planted cameras in my room." The nurse
should respond by:
