Question 1: A nurse is conducting a mental status examination on a
client admitted to the psychiatric unit. The client is wearing
mismatched clothing, has unkempt hair, and a strong body odor,
but states, "I am perfectly fine." Which of the following should the
nurse document in the MSE?
A. Inappropriate affect and pressured speech
B. Poor grooming and hygiene with lack of insight
C. Tangential thought process and labile mood
D. Impaired judgment and flight of ideas
CORRECT ANSWER: B. Poor grooming and hygiene with lack of
insight
Rationale: The client's unkempt appearance reflects poor grooming and
hygiene, documented under the appearance component of the MSE. Stating
"I am perfectly fine" despite obvious self-neglect indicates lack of insight.
There is no evidence of pressured speech, tangential thinking, or labile
mood based on the information provided .
Question 2: A nurse in the emergency department is assessing a
client who reports feeling hopeless and has a plan to overdose on
acetaminophen. The client recently experienced the loss of a
spouse. Using the SAD PERSONS scale, which factors are present in
this client's presentation?
A. Sex, age, and rational thinking loss only
B. Depression, social support loss, organized plan, and access to lethal
means
C. Previous attempt, ethanol use, and sickness only
D. Organized plan, no social support, and age over 45 only
CORRECT ANSWER: B. Depression, social support loss, organized
plan, and access to lethal means
,Rationale: The SAD PERSONS mnemonic stands for Sex, Age, Depression,
Previous attempt, Ethanol abuse, Rational thinking loss, Social supports
lacking, Organized plan, No spouse, and Sickness. This client has
depression, social support loss (recent death of spouse), an organized plan
(overdose on acetaminophen), and access to lethal means (medications at
home) .
Question 3: A nurse is performing a violence risk assessment on a
client on an inpatient psychiatric unit. Which of the following client
behaviors is the most reliable early indicator of potential violence?
A. The client sits quietly in the day room and refuses to speak with staff
B. The client paces the hallway, clenches their fists, and speaks in a loud,
demanding tone
C. The client cries quietly in their room after a phone call with family
D. The client asks to see the unit psychiatrist for a medication change
CORRECT ANSWER: B. The client paces the hallway, clenches their
fists, and speaks in a loud, demanding tone
Rationale: Pacing, fist clenching, and a loud, demanding tone are classic
behavioral indicators of escalating agitation and potential violence. These
motoric and vocal signs represent the early escalation phase on the assault
cycle, during which de-escalation interventions are most effective .
Question 4: A 34-year-old patient admitted to an inpatient
psychiatric unit refuses to take prescribed medication, stating, "I
have the right to refuse treatment." The nurse should recognize
that this right is protected under which legal principle?
A. Informed consent and patient autonomy
B. Involuntary commitment statutes
C. Duty to warn and protect third parties
D. Mandatory reporting requirements
CORRECT ANSWER: A. Informed consent and patient autonomy
Rationale: Informed consent and patient autonomy are foundational legal
principles that protect a competent patient's right to refuse treatment,
including medication. While involuntary commitment statutes address
admission criteria, they do not override a competent patient's right to
refuse specific treatments .
,Question 5: A nurse is establishing a therapeutic relationship with
a newly admitted patient experiencing severe anxiety. The nurse
demonstrates genuineness by which action?
A. Sharing personal experiences with anxiety to build rapport
B. Responding authentically to the patient without pretending to have all
answers
C. Maintaining a strictly professional distance at all times
D. Agreeing with the patient's statements regardless of accuracy
CORRECT ANSWER: B. Responding authentically to the patient
without pretending to have all answers
Rationale: Genuineness in therapeutic communication involves being
authentic, honest, and congruent in responses rather than putting on a
professional facade. Sharing personal experiences can blur professional
boundaries, and agreeing with inaccurate statements undermines
therapeutic honesty .
Question 6: A patient on a psychiatric unit becomes increasingly
agitated and verbally aggressive toward staff. The nurse's initial
intervention should focus on which approach?
A. Administering a PRN antipsychotic medication immediately
B. Calling a code for physical restraint application
C. Using verbal de-escalation techniques and offering a calm environment
D. Isolating the patient in a seclusion room for safety
CORRECT ANSWER: C. Using verbal de-escalation techniques and
offering a calm environment
Rationale: Verbal de-escalation and environmental modification are the
least restrictive interventions and should always be attempted first when
managing agitation, consistent with the principle of using the least
restrictive alternative. Medication, seclusion, and restraints are more
restrictive measures .
Question 7: A mental health nurse is assessing a patient who uses
the defense mechanism of projection. Which statement by the
patient best demonstrates this mechanism?
A. "I do not care about the exam results anymore."
B. "I will study twice as hard for the next exam."
, C. "I passed the exam because I am smarter than everyone else."
D. "I failed the exam because the teacher does not like me."
CORRECT ANSWER: D. "I failed the exam because the teacher does
not like me."
Rationale: Projection involves attributing one's own unacceptable feelings,
thoughts, or motives to another person. The patient who blames the
teacher rather than accepting personal responsibility for the exam outcome
is projecting their own feelings of inadequacy onto the teacher .
Question 8: During a mental status examination, the nurse
observes that a patient demonstrates loose associations. Which
statement by the patient would be most consistent with this
finding?
A. "I went to the store... butterflies fly south for the winter... my shoes are
brown."
B. "The weather is nice. I like sunny days at the beach."
C. "I feel sad today because my friend moved away last week."
D. "I cannot concentrate because the voices are too loud."
CORRECT ANSWER: A. "I went to the store... butterflies fly south
for the winter... my shoes are brown."
Rationale: Loose associations are characterized by speech that shifts from
one unrelated topic to another without logical connection. The statement
about going to the store, then butterflies, then shoes demonstrates this
pattern of disorganized thinking .
Question 9: A nurse is planning care for a client who has a mental
health disorder. Which of the following is appropriate to include as
a psychobiological intervention?
A. Assist the client with systematic desensitization therapy
B. Teach the client appropriate coping mechanisms
C. Assess the client for comorbid health conditions
D. Monitor the client for adverse effects of medications
CORRECT ANSWER: D. Monitor the client for adverse effects of
medications
Rationale: Monitoring for adverse effects of medications is an example of a
psychobiological intervention because it addresses the biological effects of
