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 nurse is providing discharge teaching to a client with schizophrenia who is prescribed clozapine (Clozaril). Which information should the nurse include?
- A. You need to come in for regular blood tests.
- B. This medication can cause weight loss.
- C. You can stop taking this medication once you feel better.
- D. Avoid foods high in tyramine while on this medication.
Correct answer: A
Rationale: The correct answer is A: 'You need to come in for regular blood tests.' Clozapine can cause agranulocytosis, a potentially life-threatening condition, so regular blood tests are required to monitor the client's white blood cell count. Choice B is incorrect because clozapine is associated with weight gain, not weight loss. Choice C is incorrect because the client should never stop taking clozapine abruptly due to the risk of withdrawal symptoms and symptom relapse. Choice D is incorrect because avoiding foods high in tyramine is typically associated with MAOIs, not clozapine.
3. A 45-year-old female client is admitted to the psychiatric unit for evaluation. Her husband states that she has been reluctant to leave home for the last six months. The client has not gone to work for a month and has been terminated from her job. She has not left the house since that time. This client is displaying symptoms of which disorder?
- A. Claustrophobia.
- B. Acrophobia.
- C. Agoraphobia.
- D. Necrophobia.
Correct answer: C
Rationale: The correct answer is C, Agoraphobia. Agoraphobia involves the fear of situations where escape might be difficult, often leading to the individual avoiding public spaces or leaving their home. In this case, the client's reluctance to leave home, not going to work, and staying indoors for an extended period align with the symptoms of agoraphobia. Choices A, B, and D are incorrect. Claustrophobia is the fear of confined spaces, acrophobia is the fear of heights, and necrophobia is the fear of death or dead things, none of which are consistent with the client's symptoms described in the scenario.
4. A client with panic disorder is prescribed sertraline (Zoloft). What is the most important information for the nurse to provide?
- A. You should take this medication at the same time every day.
- B. It may take several weeks for you to feel the full effect.
- C. This medication may cause a significant increase in appetite.
- D. You may experience dizziness, so avoid driving.
Correct answer: B
Rationale: The correct answer is B. SSRIs like sertraline may take several weeks to reach their full therapeutic effect, so it's important to inform the client to be patient with the treatment. Choice A is not the most crucial information regarding sertraline. Choice C is not a common side effect of sertraline. Choice D is important but not as crucial as informing about the delayed onset of action.
5. A client who has been admitted to the psychiatric unit tells the nurse, 'My problems are so bad that no one can help me.' Which response is best for the nurse to make?
- A. How can I help?
- B. Things probably aren't as bad as they seem right now.
- C. Let's talk about what is right with your life.
- D. I hear how miserable you are, but things will get better soon.
Correct answer: A
Rationale: Offering self shows empathy and caring (A) and is the best choice provided. (B) dismisses the client's feelings and reality. (C) avoids addressing the client's concerns directly and may come across as invalidating. Although (D) starts with acknowledging the client's feelings, the second part about things getting better soon can be perceived as offering false reassurance, which is not recommended in therapeutic communication.
