ATI RN Mental Health Proctored Exam
2026 with NGN 270 Questions Rationales
and 100% Correct Verified legit Answers
A high-density, 270-question clinical practice exam database engineered
explicitly for registered nursing students preparing for their proctored specialty
examinations and NCLEX-RN licensure. This comprehensive segment isolates
complex diagnostic scenarios, matching advanced psychiatric conditions with
ethical nursing practice. The dataset details essential testing concepts including
psychopharmacology safety protocols, metabolic syndrome tracking,
extrapyramidal side effect management, legal parameters of involuntary
placement, and therapeutic communication matrices. Every entry features the
correct multiple-choice variant highlighted in bold paired with an explicit,
italicised nursing rationale to reinforce clinical judgment, patient advocacy, and
critical thinking execution.
1. A nurse is caring for a client who has schizophrenia and is experiencing auditory
hallucinations. The client states, "The voices are telling me that my food is poisoned."
Which of the following responses should the nurse make?
A) "No one is trying to poison your food, so it is safe to eat."
B) "I understand that you hear voices, but I do not hear anything. It is safe to eat
your meal."
C) "Why do you think someone would want to poison your food?"
D) "I will taste your food for you to prove that it is safe."
Rationale: This response presents objective reality and validates the client's feelings
without reinforcing, agreeing with, or arguing against the hallucination.
2. A nurse is reviewing the laboratory results of a client who is receiving lithium carbonate
for bipolar disorder. The client's serum lithium level is 1.8 mEq/L. Which of the following
actions should the nurse take?
A) Administer the next prescribed dose as scheduled.
B) Hold the medication and notify the provider immediately.
C) Request a repeat lithium level to be drawn in 24 hours.
D) Instruct the client to restrict their oral fluid intake.
Rationale: The therapeutic range for lithium is 0.6 to 1.2 mEq/L. A level of 1.8 mEq/L
, indicates moderate to severe toxicity, requiring the nurse to withhold the drug and
immediately assess for toxicity symptoms like coarse tremors or vomiting.
3. A nurse is admitting a client who has anorexia nervosa. Which of the following clinical
findings should the nurse expect?
A) Tachycardia, hypertension, and hyperthermia
B) Bradycardia, hypotension, and lanugo
C) Diarrhea, hyperreflexia, and moist skin
D) Menorrhagia, polyuria, and bounding pulses
Rationale: Anorexia nervosa causes starvation-induced physiological adaptations,
including bradycardia, hypotension, hypothermia, amenorrhea, and the development of
lanugo (fine, downy hair) to preserve body heat.
4. A nurse is caring for a client who is experiencing a severe panic attack. Which of the
following actions should the nurse take first?
A) Teach the client deep-breathing exercises.
B) Stay with the client and speak using short, simple sentences.
C) Guide the client to a busy dayroom area for a distraction.
D) Administer a prescribed PRN dose of an oral antidepressant.
Rationale: During a severe panic attack, a client's cognitive processing is extremely
narrow. Staying with the client provides immediate physical safety, and short, simple
communication matches their diminished attention span.
5. A nurse is assessing a client who has alcohol use disorder and is experiencing
withdrawal. Which of the following findings should the nurse identify as an early
manifestation of withdrawal?
A) Bradycardia, somnolence, and severe muscle flaccidity
B) Tachycardia, diaphoresis, and fine hand tremors
C) Profound hypothermia, bradycardia, and urinary retention
D) Auditory hallucinations and a generalized tonic-clonic seizure
Rationale: Early signs of alcohol withdrawal typically begin within 6 to 8 hours after the
last drink and feature autonomic hyperactivity, including tachycardia, hypertension,
diaphoresis, anxiety, and tremors.
6. A nurse is reinforcing teaching with a client who has a new prescription for phenelzine,
an MAOI. Which of the following dietary choices should the nurse instruct the client to
avoid entirely?
A) Fresh apples, oranges, and low-fat milk
B) Aged cheddar cheese, pepperoni, and red wine
C) Whole wheat bread, white rice, and carrots
D) Grilled chicken breast, scrambled eggs, and green beans
Rationale: MAOIs block the breakdown of tyramine. Ingesting foods rich in tyramine
(aged cheeses, cured/smoked meats, fermented products, red wine) can precipitate a
life-threatening hypertensive crisis.
7. A nurse is evaluating a client who has major depressive disorder and started taking
fluoxetine 3 days ago. The client states, "This medicine isn't working, I still feel sad."
Which of the following responses should the nurse make?
A) "We will need to ask your provider to increase the dose immediately."
B) "You should stop taking the medication if you do not see an improvement."
C) "It typically takes 2 to 4 weeks of consistent use to feel the full therapeutic
, effects."
D) "This medication only works if you participate in rigorous physical exercise."
Rationale: Selective serotonin reuptake inhibitors (SSRIs) like fluoxetine require several
weeks of continuous administration to achieve therapeutic plasma levels and alter
neurotransmitter adaptation in the brain.
8. A nurse is assessing a client who has a history of opioid use disorder and is
experiencing acute withdrawal. Which of the following clinical manifestations should the
nurse expect?
A) Rhinorrhea, pupillary dilation, piloerection, and yawning
B) Pupillary constriction, somnolence, bradycardia, and dry skin
C) Constipation, urinary retention, hypothermia, and bradypnea
D) Bounding pulses, horizontal nystagmus, and high-spiking fever
Rationale: Opioid withdrawal produces uncomfortable, flu-like symptoms opposite to the
drug's acute effects, including rhinorrhea, lacrimation, sweating, dilated pupils, yawning,
piloerection ("goosebumps"), and abdominal cramps.
9. A nurse is caring for a client who has schizophrenia and is prescribed clozapine. Which
of the following laboratory values must the nurse monitor closely before and during
therapy?
A) Serum creatinine and blood urea nitrogen
B) Absolute neutrophil count (ANC)
C) Serum amylase and lipase levels
D) Prothrombin time and INR
Rationale: Clozapine carries a black-box warning for agranulocytosis. Regular
monitoring of the ANC is federally mandated to detect severe, life-threatening
leukopenia.
10. A nurse is conducting a counseling session for a client who uses intellectualisation as a
defense mechanism. Which of the following descriptions matches this behavior?
A) Displacing emotional anger onto a less threatening object or person.
B) Completely blocking an overwhelming, traumatic event from conscious awareness.
C) Using abstract, analytical reasoning to avoid experiencing painful or stressful
emotions.
D) Attributing one's own unacceptable feelings or impulses onto another individual.
Rationale: Intellectualisation is a defense mechanism where the client analyzes a
stressful situation using clinical or academic facts to isolate themselves from the
underlying painful emotion.
11. A nurse is caring for a client who is admitted for treatment of obsessive-compulsive
disorder (OCD). The client spends 2 hours every morning washing their hands. Which
of the following interventions should the nurse implement initially?
A) Lock the bathroom doors to completely prevent the handwashing ritual.
B) Allow the client enough time to perform the ritual at the start of treatment.
C) Administer an emergency dose of haloperidol when the ritual begins.
D) Instruct the client that handwashing must be completed in under 5 minutes.
Rationale: Early in OCD treatment, abruptly stopping compulsive rituals increases
anxiety to panic levels. The nurse should initially allow time for the behavior while
gradually working to substitute healthier coping mechanisms.
, 12. A nurse is caring for a client who has borderline personality disorder. The client states
to the night shift nurse, "You are the only good nurse here; the day shift nurse is
completely incompetent and mean." The nurse should identify this statement as which
of the following defense mechanisms?
A) Projection
B) Splitting
C) Rationalisation
D) Reaction formation
Rationale: Splitting is a primitive defense mechanism common in borderline personality
disorder where individuals perceive others as entirely "all good" or "all bad," failing to
integrate positive and negative qualities.
13. A nurse is preparing a client for an electroconvulsive therapy (ECT) procedure. Which of
the following medications should the nurse expect to administer as a short-acting
muscle relaxant during the procedure?
A) Intravenous diazepam
B) Succinylcholine
C) Methohexital
D) Atropine sulfate
Rationale: Succinylcholine is a depolarizing neuromuscular blocker administered during
ECT to paralyze skeletal muscles, preventing severe muscle contractions and bone
fractures during the induced seizure.
14. A nurse is monitoring a client who has schizophrenia and is taking haloperidol. The
nurse notes a high temperature of 39.5°C (103.1°F), severe "lead-pipe" muscle rigidity,
altered consciousness, and autonomic instability. Which of the following life-threatening
complications should the nurse suspect?
A) Acute dystonic reaction
B) Akathisia crisis
C) Neuroleptic malignant syndrome (NMS)
D) Serotonin syndrome
Rationale: NMS is a rare, severe reaction to antipsychotic medications. It is
characterized by hyperpyrexia, profound muscle rigidity, altered mental status, and
autonomic dysfunction (tachycardia, labile blood pressure).
15. A nurse is conducting a mental status examination on a client who exhibits neologisms
during conversation. Which of the following examples best demonstrates a neologism?
A) Rhyming words continuously without making logical sense.
B) Repeating the exact words spoken by the nurse.
C) Rapidly shifting from one unlinked topic to another.
D) Inventing completely new words that have meaning only to the client.
Rationale: Neologisms are meaningless, self-invented words created by clients with
thought disorders, representing a profound alteration in thought process.
16. A nurse is caring for a client who has a new prescription for lithium carbonate. Which of
the following baseline laboratory results must the nurse review before initiating therapy?
A) Serum amylase and liver enzymes
B) Serum creatinine, BUN, and thyroid-stimulating hormone (TSH)
C) Absolute neutrophil count and platelet count
D) Serum ionized calcium and glucose levels
