ATI RN Mental Health Exam 2026 | Level 3
| Practice Questions, Answers and
Rationales | Complete Review.
1. A nurse is admitting a client to an inpatient psychiatric unit. Which action best demonstrates
the ethical principle of autonomy?
A. Allowing the client to refuse a prescribed medication after being informed of the
consequences
B. Restricting visitation until the client demonstrates improved behavior
C. Making treatment decisions on the client's behalf to prevent harm
D. Sharing the client's diagnosis with family without consent
Rationale: Autonomy is the client's right to make informed decisions about their own care,
including the right to refuse treatment. Beneficence (acting in the client's best interest) and
nonmaleficence (do no harm) do not override a competent adult's autonomy. Confidentiality
requires consent before disclosure.
2. Which statement by the nurse indicates an understanding of the concept of least restrictive
environment?
A. "I will place the client in seclusion at the first sign of agitation."
B. "I will attempt verbal de-escalation before considering physical restraints."
C. "Restraints should be applied routinely for all clients at risk for falls."
D. "The client must earn the right to leave seclusion by behaving appropriately."
Rationale: The least restrictive alternative doctrine requires that the least restrictive
intervention be attempted first. Verbal de-escalation, milieu support, PRN medication, and quiet
time precede seclusion or restraint. Restraints require a provider's order, are time-limited, and
are never punitive or routine.
3. A client says, "I don't want to take that medication. It made me feel like a zombie last time."
Which response by the nurse is most therapeutic?
,A. "You have to take it; it's doctor's orders."
B. "That medication is the best one for your condition."
C. "Tell me more about how the medication made you feel."
D. "If you refuse, you'll never get better."
Rationale: Exploring the client's experience validates concerns and gathers assessment data
(adverse effects) that can guide the provider to adjust therapy. The other options are dismissive,
authoritarian, or give false reassurance.
4. A nurse is assessing a client who reports hearing voices telling her to harm herself. Which is
the priority nursing action?
A. Ask the client to describe the content of the voices in detail
B. Document the finding and continue the interview
C. Ensure the client's immediate safety and notify the provider
D. Tell the client the voices are not real
Rationale: Command hallucinations to harm self or others represent an immediate safety
risk. Safety is always the priority, followed by provider notification, appropriate supervision, and
documentation. Arguing with the client about the voices is nontherapeutic.
5. Which finding best indicates the nurse has established trust in the nurse-client relationship?
A. The client agrees with everything the nurse says
B. The client discloses a history of childhood trauma
C. The client asks the nurse for personal advice about marriage
D. The client requests that the nurse keep a secret about self-harm
Rationale: Trust is demonstrated when a client feels safe enough to disclose sensitive
information. Agreeing with everything may indicate people-pleasing; requests for personal
advice or to keep secrets about self-harm signal boundary and safety issues that require
therapeutic management, not trust.
6. A nurse is caring for a client on a psychiatric unit. Which behavior by the nurse constitutes
a boundary violation?
,A. Using therapeutic communication techniques during a counseling session
B. Maintaining professional dress and demeanor
C. Accepting a $100 gift from the client and sharing personal problems with the client
D. Documenting the client's statements objectively
Rationale: Boundary violations occur when the nurse's needs are met at the client's
expense (self-disclosure of personal problems, accepting significant gifts, becoming emotionally
or physically involved). Boundary crossings may be minor and context-dependent; violations
harm the therapeutic relationship.
7. A client newly admitted with mania is unable to sit still during the admission interview. Which
action should the nurse take?
A. Insist the client sit quietly until the interview is complete
B. Administer a PRN antipsychotic immediately
C. Shorten the interview and provide a safe, low-stimulation environment
D. Place the client in seclusion to complete the assessment
Rationale: Clients with mania have difficulty concentrating and tolerating stimulation. The
nurse should adapt the interview (brief, structured, low-stimulation) and defer nonessential
questions. Sedation and seclusion are not first-line for a non-dangerous client.
8. Which client should the nurse assess first after receiving the shift report?
A. A client with depression who is sleeping in her room
B. A client with anxiety who is pacing in the hallway
C. A client who is post-ECT and confused, with a new onset of agitation
D. A client with schizophrenia who is attending group therapy
Rationale: A change in mental status with agitation following ECT may indicate a
complication (e.g., postictal confusion, hypoxia, or delirium) and requires immediate
assessment. The other clients are stable or experiencing expected symptoms.
9. A nurse is teaching a client about the purpose of a therapeutic milieu. Which statement by
the client indicates understanding?
, A. "The milieu is mainly for keeping clients under constant surveillance."
B. "The milieu is where medications are administered."
C. "The milieu provides a safe, structured environment that promotes healing and social
interaction."
D. "The milieu is a form of punishment for disruptive behavior."
Rationale: The therapeutic milieu is a structured, safe, supportive environment that
promotes safety, reality orientation, social skills, and group interaction. Surveillance and
medication administration are components of care, not the purpose of the milieu; the milieu is
never punitive.
10. Which client right is protected by informed consent?
A. The right to refuse all treatment without consequence
B. The right to receive information about risks, benefits, and alternatives before agreeing to
treatment
C. The right to demand a specific medication
D. The right to be discharged immediately upon request, regardless of risk
Rationale: Informed consent requires that the client receive complete information (nature
of treatment, risks, benefits, alternatives, and consequences of refusal) and voluntarily agree.
Refusing treatment may have consequences (e.g., involuntary hold if dangerous); clients cannot
demand specific medications.
11. A nurse is documenting in a client's chart. Which entry is most appropriate?
A. "Client was manipulative and annoying during group."
B. "Client seemed crazy today."
C. "Client stated, 'I feel like no one cares about me.' Affect flat; remained in room during
group."
D. "Client is a typical borderline who split staff."
Rationale: Documentation must be objective, specific, and free of judgmental or
stigmatizing language. Quoting the client and describing observable behaviors is appropriate.
The other entries are subjective, derogatory, and unprofessional.
