Question 1: A nurse is assessing a client who has been diagnosed
with major depressive disorder. The client states, "I feel so
worthless and empty inside." Which of the following is the priority
nursing action?
A. Encourage the client to attend a group therapy session
B. Assess the client for suicidal ideation and intent
C. Administer the prescribed antidepressant medication
D. Teach the client about the importance of sleep hygiene
CORRECT ANSWER: B. Assess the client for suicidal ideation and
intent
Rationale: When a client expresses feelings of worthlessness and
emptiness, the priority nursing action is to assess for suicidal ideation and
intent. Safety is always the first consideration in mental health nursing.
Feelings of worthlessness are a major risk factor for suicide, and the nurse
must determine whether the client has a plan, means, and intent before
addressing other aspects of care.
Question 2: A client diagnosed with schizophrenia is experiencing
auditory hallucinations telling him to harm himself. Which of the
following responses by the nurse is most therapeutic?
A. "You should ignore those voices; they aren't real."
B. "Tell me what the voices are saying to you right now."
C. "I will turn up the television so you can't hear them."
D. "Why do you think the voices are telling you to do that?"
CORRECT ANSWER: B. "Tell me what the voices are saying to you
right now."
,Rationale: Asking the client to describe what the voices are saying is a
therapeutic communication technique that acknowledges the client's
experience and allows the nurse to assess the content of the hallucinations,
particularly if they are command hallucinations that could lead to harm.
Telling the client to ignore the voices or distracting with television
dismisses the client's experience. Asking "why" is nontherapeutic as it
demands explanation and may increase anxiety.
Question 3: A nurse is caring for a client with bipolar I disorder
who is currently in a manic episode. Which of the following
behaviors should the nurse expect to observe?
A. Psychomotor retardation and anhedonia
B. Decreased need for sleep and pressured speech
C. Social withdrawal and flat affect
D. Obsessive-compulsive behaviors and rituals
CORRECT ANSWER: B. Decreased need for sleep and pressured
speech
Rationale: During a manic episode of bipolar I disorder, clients typically
exhibit decreased need for sleep, pressured speech, grandiosity, increased
goal-directed activity, and distractibility. Psychomotor retardation and
anhedonia are characteristic of depressive episodes. Social withdrawal and
flat affect are negative symptoms of schizophrenia. Obsessive-compulsive
behaviors are characteristic of OCD.
Question 4: A client is admitted to the psychiatric unit with a
diagnosis of generalized anxiety disorder. Which of the following
findings should the nurse expect?
A. Fear of specific objects or situations
B. Recurrent, unexpected panic attacks
C. Excessive worry about multiple areas of life
D. Intrusive thoughts and compulsive rituals
CORRECT ANSWER: C. Excessive worry about multiple areas of life
Rationale: Generalized anxiety disorder is characterized by excessive,
uncontrollable worry about multiple areas of life, such as work, health,
finances, and family, occurring more days than not for at least six months.
Fear of specific objects or situations suggests a specific phobia. Recurrent
,unexpected panic attacks suggest panic disorder. Intrusive thoughts and
compulsive rituals suggest obsessive-compulsive disorder.
Question 5: A nurse is assessing a client who has been taking
lithium carbonate for bipolar disorder. Which of the following
findings indicates possible lithium toxicity?
A. Blood pressure of 118/76 mm Hg
B. Serum lithium level of 1.8 mEq/L
C. Heart rate of 88 beats per minute
D. Respiratory rate of 18 breaths per minute
CORRECT ANSWER: B. Serum lithium level of 1.8 mEq/L
Rationale: The therapeutic serum lithium level is typically 0.6 to 1.2 mEq/L.
A level of 1.8 mEq/L is above the therapeutic range and indicates lithium
toxicity. Early signs of toxicity include coarse hand tremors, nausea,
vomiting, diarrhea, and lethargy. The nurse should hold the medication and
notify the provider immediately. The other vital signs listed are within
normal limits.
Question 6: A client with major depressive disorder has been
prescribed sertraline. Which of the following instructions should
the nurse include in the teaching?
A. "You should notice improvement within 24 to 48 hours."
B. "Stop the medication immediately if you feel better."
C. "It may take 2 to 4 weeks before you notice improvement."
D. "You can drink alcohol in moderation while taking this medication."
CORRECT ANSWER: C. "It may take 2 to 4 weeks before you notice
improvement."
Rationale: SSRIs such as sertraline typically take 2 to 4 weeks to produce
therapeutic effects. Clients should be informed of this delay to prevent
discouragement and premature discontinuation. The medication should not
be stopped abruptly even when feeling better, as this can cause
discontinuation syndrome. Alcohol should be avoided because it can
worsen depression and increase sedation.
Question 7: A nurse is planning care for a client who is
experiencing a panic attack. Which of the following interventions
should the nurse implement first?
, A. Teach the client relaxation techniques
B. Stay with the client and remain calm
C. Administer a prescribed benzodiazepine
D. Move the client to a quiet, low-stimulation area
CORRECT ANSWER: B. Stay with the client and remain calm
Rationale: During a panic attack, the client experiences intense fear and a
sense of losing control. The nurse's first intervention should be to stay with
the client and remain calm, providing a sense of safety and security. This
therapeutic presence helps decrease the client's anxiety. Once the client is
calmer, the nurse can move the client to a quiet area, administer
medication, and teach relaxation techniques.
Question 8: A client with schizophrenia has been prescribed
clozapine. Which of the following laboratory values should the
nurse monitor most closely?
A. Serum potassium level
B. Absolute neutrophil count
C. Serum creatinine level
D. Liver function tests
CORRECT ANSWER: B. Absolute neutrophil count
Rationale: Clozapine carries a risk of agranulocytosis, a potentially life-
threatening condition characterized by a severe decrease in neutrophils.
Clients must have their absolute neutrophil count monitored regularly,
typically weekly for the first six months and then biweekly. If the ANC
drops below a certain level, the medication must be discontinued. While
liver function tests are also monitored, ANC is the most critical due to the
risk of severe infection.
Question 9: A nurse is conducting a suicide risk assessment. Which
of the following client statements indicates the highest level of
suicide risk?
A. "I sometimes think about what it would be like to be dead."
B. "I have a plan to take all my pills tonight at 8 pm."
C. "I feel like a burden to my family sometimes."
D. "I wish I could just disappear for a while."
