2026 Practice Test — 70 NCLEX-Style Questions
Answers in bold italic • Rationales in italic
,1. A client says, "I feel like nobody cares about me." Which response is most
therapeutic?
A. I'm sure your family cares about you.
B. Why do you feel that way?
C. You feel like no one cares about you right now?
D. Everyone feels that way sometimes.
Correct Answer: C
Rationale: Reflecting the client's feeling back is therapeutic; it validates emotion without dismissing it.
"Why" questions can feel confrontational, and the other options minimize the client's feelings with false
reassurance.
2. A client with generalized anxiety disorder asks how buspirone works. The nurse
should include which teaching point?
A. It works immediately to relieve anxiety.
B. It may take 2 to 4 weeks for full effect.
C. You may become physically dependent on it.
D. Take it only when you feel anxious.
Correct Answer: B
Rationale: Buspirone is not for immediate or PRN use and takes 2 to 4 weeks for full therapeutic effect;
unlike benzodiazepines, it is non-habit-forming.
3. Which assessment finding in a client taking lithium indicates toxicity?
A. Lithium level of 0.8 mEq/L
B. Mild hand tremor
C. Coarse tremor and ataxia
D. Slight increase in thirst
Correct Answer: C
Rationale: Coarse tremor and ataxia indicate lithium toxicity and require immediate follow-up. A level
of 0.8 mEq/L is within the therapeutic range, and mild tremor or thirst are common, expected side
effects.
4. A client in a manic episode is pacing the unit and speaking rapidly. What is the
priority nursing intervention?
, A. Engage the client in a group activity
B. Provide a structured, low-stimulation environment
C. Encourage the client to sit and eat a full meal
D. Ask the client to explain their thoughts in detail
Correct Answer: B
Rationale: Reducing environmental stimulation is the priority for a manic client. A structured, low-
stimulus environment helps prevent escalation and physical exhaustion.
5. Which statement by a client with schizophrenia who is experiencing auditory
hallucinations requires the most therapeutic nursing response?
A. I hear voices telling me to hurt myself.
B. The voices are just background noise.
C. I hear voices sometimes at night.
D. The voices went away when I took my medication.
Correct Answer: A
Rationale: Command hallucinations instructing self-harm are a safety priority and require immediate
further assessment and intervention over the other, lower-risk statements.
6. A client newly prescribed haloperidol develops a high fever, muscle rigidity, and
confusion. The nurse suspects:
A. Serotonin syndrome
B. Neuroleptic malignant syndrome
C. Tardive dyskinesia
D. Anticholinergic crisis
Correct Answer: B
Rationale: Fever, rigidity, and altered mental status in a client on an antipsychotic strongly suggest
neuroleptic malignant syndrome (NMS), a life-threatening emergency.
7. Which lab finding would the nurse expect in a client who frequently purges?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hyperglycemia
