HESI Mental Health Practice Exam
1. An adolescent who attempted suicide with a drug overdose arrives in the emergency department with an empty 30-tablet bottle of acetaminophen (Tylenol). Which action should the nurse implement?
- A. Administer acetylcysteine (Mucomyst).
- B. Monitor cardiac rhythm for flat T waves.
- C. Check both serum AST and ALT levels.
- D. Prepare to administer Syrup of Ipecac.
Correct answer: A
Rationale: The correct action for the nurse to implement is to administer acetylcysteine (Mucomyst). Acetylcysteine is the antidote for acetaminophen overdose and should be administered promptly to prevent liver damage. Monitoring cardiac rhythm for flat T waves (Choice B) is not specific to acetaminophen overdose and is more related to cardiac conditions. Checking serum AST and ALT levels (Choice C) may be done later but is not the initial priority in this situation. Similarly, preparing to administer Syrup of Ipecac (Choice D) is not recommended anymore in cases of overdose as it can cause more harm.
2. A male client turns over a table in the dayroom of a psychiatric unit and threatens to throw a chair at another client. Which action is most important for the nurse to implement?
- A. Calmly approach the client and remove the chair from the client.
- B. Obtain staff assistance to help diffuse the escalating situation.
- C. Offer feedback about the client's behavior.
- D. Summon the hospital security guards as a 'show of force.'
Correct answer: B
Rationale: In a situation where a client is displaying aggressive behavior, the most important action for the nurse to implement is to obtain staff assistance to help diffuse the escalating situation. This approach ensures the safety of all individuals involved and prevents the situation from escalating further. Calmly approaching the client and removing the chair directly could agitate the client further and pose a risk to the nurse. Offering feedback about the client's behavior may not address the immediate safety concerns. Summoning hospital security guards as a 'show of force' should be a last resort after other de-escalation attempts have failed, as it may further provoke the client.
3. Which client outcome indicates improvement for a client who is admitted with auditory hallucinations?
- A. Argues with the voices.
- B. Tells when voices decrease.
- C. Follows what the voices say.
- D. Tells the nurse what the voices say.
Correct answer: B
Rationale: The correct answer is B: 'Tells when voices decrease.' This outcome indicates improvement because it shows that the client is experiencing a reduction in auditory hallucinations. By communicating that the voices are decreasing, it suggests that the client's symptoms are improving and the treatment is effective. Choices A, C, and D are incorrect. Arguing with the voices (A) indicates ongoing engagement with the hallucinations, which is not a positive outcome. Following what the voices say (C) suggests compliance with the hallucinations, which is not indicative of improvement. Lastly, telling the nurse what the voices say (D) does not necessarily demonstrate a reduction in hallucinations or improvement in the client's condition.
4. A LVN/LPN is caring for a client with anorexia nervosa. The nurse is monitoring the behavior of the client and understands that a client with anorexia nervosa manages anxiety by:
- A. Engaging in immoral acts
- B. Always reinforcing self-approval
- C. Observing rigid rules and regulations
- D. Having the need always to make the right decision
Correct answer: C
Rationale: Clients with anorexia nervosa often manage anxiety by adhering strictly to rules and regulations as a way to maintain control. Choice A is incorrect because engaging in immoral acts is not a common coping mechanism for clients with anorexia nervosa. Choice B is incorrect as self-approval is not typically the primary way clients with anorexia nervosa manage anxiety. Choice D is incorrect because while clients with anorexia nervosa may have a need to make the right decision, it is not the primary way they manage their anxiety.
5. A female client on the psychiatric unit tells the nurse that she feels like ending her life because she can no longer deal with her depression. What is the nurse's priority intervention?
- A. Stay with the client and ensure her safety.
- B. Inform the client that she is safe in the hospital.
- C. Document the client's statements in her medical record.
- D. Encourage the client to join a group therapy session.
Correct answer: A
Rationale: The correct answer is to stay with the client and ensure her safety. Ensuring the client's safety is the top priority when a client expresses suicidal ideation. Staying with the client can help prevent self-harm while further assessment and interventions are arranged. Choice B is incorrect because simply informing the client that she is safe in the hospital does not address the immediate need for safety. Choice C is incorrect as while documentation is important, it is not the priority when a client's safety is at risk. Choice D is also incorrect as encouraging the client to join a group therapy session is not appropriate when the client is in crisis and expressing suicidal thoughts.
