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 with mental illness and substance dependency tells the mental health nurse that he has started using illegal drugs again and wants to seek treatment. Since he has a dual diagnosis, which person is best for the nurse to refer this client to first?
- A. The emergency room nurse.
- B. His case manager.
- C. The clinic healthcare provider.
- D. His support group sponsor.
Correct answer: B
Rationale: The case manager (B) is responsible for coordinating community services, making them the best person to refer the client to first as they can describe available treatment options. The emergency room nurse (A) is unnecessary unless the client's behaviors pose imminent threats. The clinic healthcare provider (C) and support group sponsor (D) may be useful but coordinating a treatment program tailored to the client's needs is the priority in this scenario.
3. A client with major depressive disorder is prescribed an SSRI. After one week, the client reports feeling no improvement in mood. What is the best response by the RN?
- A. It is common for antidepressants to take several weeks to have an effect.
- B. We may need to switch to a different medication.
- C. You should feel better by now, let's discuss this with your doctor.
- D. Maybe you are not taking the medication as prescribed.
Correct answer: A
Rationale: The correct response is A: 'It is common for antidepressants to take several weeks to have an effect.' This response is appropriate because SSRI and other antidepressants often require several weeks to exhibit improvement in mood. It is crucial to educate the client about this delay to manage expectations and promote adherence to the medication regimen. Choice B is incorrect as switching medications prematurely is not typically recommended after just one week. Choice C is incorrect because it sets unrealistic expectations for immediate improvement. Choice D is incorrect as it may come across as accusatory and should not be the initial response.
4. On admission to a residential care facility, an elderly female client tells the nurse that she enjoys cooking, quilting, and watching television. Twenty-four hours after admission, the nurse notes that the client is withdrawn and isolated. It is best for the nurse to encourage this client to become involved in which activity?
- A. Clean the unit kitchen cabinets.
- B. Participate in a group quilting project.
- C. Watch television in the activity room.
- D. Bake a cake for a resident's birthday.
Correct answer: B
Rationale: Peer interaction in a group activity (B) such as participating in a group quilting project will help to prevent social isolation and withdrawal. This will provide the elderly client with an opportunity to engage with others, share experiences, and feel a sense of belonging. Choices (A, C, and D) are activities that can be accomplished alone, without peer interaction, which may not effectively address the client's feelings of withdrawal and isolation.
5. Which action should the nurse implement first for a client experiencing alcohol withdrawal?
- A. Apply vest or extremity restraints.
- B. Give an alpha-adrenergic blocker.
- C. Provide a diet high in protein and calories.
- D. Prepare the environment to prevent self-injury.
Correct answer: D
Rationale: The correct action for the nurse to implement first for a client experiencing alcohol withdrawal is to prepare the environment to prevent self-injury. Clients undergoing alcohol withdrawal are at risk of seizures and other symptoms that may lead to self-harm. By ensuring a safe environment, the nurse can mitigate the risk of injury. Applying restraints (Choice A) should only be considered if less restrictive measures fail, as restraints can agitate the client further. Giving an alpha-adrenergic blocker (Choice B) may be part of the treatment plan for alcohol withdrawal but is not the first action to take. Providing a diet high in protein and calories (Choice C) is important for overall health but is not the priority when addressing immediate safety concerns.
