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. In observing a client who is pacing, agitated, and presenting aggressive gestures, with rapid speech pattern and belligerent affect, what is the immediate priority of care for the nurse?
- A. Provide safety for the client and other clients on the unit
- B. Provide the clients on the unit with a sense of comfort and safety
- C. Assist the staff in caring for the client in a controlled environment
- D. Offer the client a less stimulated area to calm down and gain control
Correct answer: A
Rationale: In a situation where a client is displaying aggression and agitation, the immediate priority of care for the nurse is to ensure safety for the client and others on the unit. Providing a safe environment and implementing calming measures take precedence over other interventions. Option A is the correct choice as it addresses the crucial need for safety in a potentially volatile situation. Options B, C, and D, although important, do not address the primary concern of ensuring safety for all individuals involved.
3. A client with schizophrenia is admitted to the psychiatric care unit for aggressive behavior, auditory hallucinations, and potential for self-harm. The client has not been taking medications as prescribed and insists that the food has been poisoned and refuses to eat. What intervention should the RN implement?
- A. Assure the client that all food served in the hospital is safe to eat.
- B. Tell the client that irrational thinking is a symptom of schizophrenia.
- C. Obtain an order for a tube feeding for the client.
- D. Provide the client with food in unopened containers.
Correct answer: D
Rationale: The correct intervention is to provide the client with food in unopened containers. This approach can help alleviate the client's fear of poisoning and encourage eating. Choice A may not address the client's specific fear and may be perceived as dismissive. Choice B, while providing information about symptoms of schizophrenia, does not address the immediate issue of the client's refusal to eat due to the fear of poisoning. Choice C of obtaining an order for tube feeding is premature and invasive before exploring less restrictive options.
4. A client with depression is started on a selective serotonin reuptake inhibitor (SSRI). The client asks, 'How long will it take for this medication to work?' What is the best response by the nurse?
- A. It may take 2 to 4 weeks before you start feeling better.
- B. You should start feeling better within a few days.
- C. The medication works immediately to improve your mood.
- D. It may take up to 8 weeks for the medication to take full effect.
Correct answer: D
Rationale: Explaining that it may take up to 8 weeks for the medication to take full effect provides the client with a realistic expectation. SSRI medications typically require time to build up in the body and exert their therapeutic effects. Choice A is incorrect as it underestimates the time frame required for the medication to work. Choice B is incorrect as SSRIs do not produce immediate effects. Choice C is incorrect as it falsely states that the medication works immediately, which is not true for SSRIs.
5. A client with borderline personality disorder is admitted to the psychiatric unit after a suicide attempt. The client frequently expresses feelings of emptiness and fears of abandonment. What is the most therapeutic nursing approach for this client?
- A. Encourage the client to participate in all group activities.
- B. Set clear and consistent boundaries while providing empathy.
- C. Reassure the client that the staff will not abandon them.
- D. Explore the client's past relationships in depth.
Correct answer: B
Rationale: The most therapeutic nursing approach for a client with borderline personality disorder, who frequently expresses feelings of emptiness and fears of abandonment, is to set clear and consistent boundaries while providing empathy. This approach helps manage the client's fear of abandonment and feelings of emptiness, which are common in borderline personality disorder. Option A may overwhelm the client in a group setting without addressing their specific needs. Option C, while well-intentioned, may not fully address the underlying issues and may create dependency. Option D delves into the client's past relationships, which may be inappropriate and trigger emotional distress in a vulnerable client.
