HESI Mental Health Practice Exam
1. A young adult female client is admitted to a psychiatric facility with a medical diagnosis of bulimia nervosa. Which nursing intervention has the highest priority?
- A. Schedule the client for group therapy with other clients with bulimia nervosa.
- B. Assign the client's care to a nurse with relevant experience in eating disorders.
- C. Monitor the client carefully for binging and purging activities.
- D. Assess and report the client's electrolyte status to the healthcare provider.
Correct answer: D
Rationale: The correct answer is D. Assessing and reporting the client's electrolyte status to the healthcare provider is the highest priority in a client with bulimia nervosa. Electrolyte imbalances, such as hypokalemia and metabolic alkalosis, are common due to purging behaviors associated with bulimia. Monitoring electrolyte levels is crucial to prevent life-threatening complications. Choices A, B, and C are incorrect because while therapy and monitoring for binging activities are important, addressing the electrolyte imbalances caused by purging behaviors takes precedence in the immediate care of a client with bulimia nervosa.
2. A client with generalized anxiety disorder is being treated with lorazepam (Ativan). What is the most important teaching point for the LPN/LVN to reinforce?
- A. Take the medication on an empty stomach.
- B. Avoid drinking alcohol while taking this medication.
- C. This medication may cause drowsiness, so avoid driving.
- D. You can stop taking the medication once you feel better.
Correct answer: B
Rationale: The most important teaching point for the LPN/LVN to reinforce is to avoid drinking alcohol while taking lorazepam (Ativan). Alcohol can enhance the sedative effects of lorazepam, increasing the risk of severe side effects and complications. Choice A is incorrect because lorazepam can be taken with or without food. Choice C is not the most critical teaching point, although it is essential to avoid activities that require mental alertness until the effects of the medication are known. Choice D is incorrect because abruptly stopping lorazepam can lead to withdrawal symptoms and should only be done under medical supervision.
3. The nurse is preparing to administer phenelzine sulfate (Nardil) to a client on the psychiatric unit. Which complaint related to administration of this drug should the nurse expect this client to make?
- A. My mouth feels like cotton.
- B. That medication gives me indigestion.
- C. This pill gives me diarrhea.
- D. My urine looks pink.
Correct answer: A
Rationale: Dry mouth is a common side effect of MAO inhibitors like phenelzine due to their anticholinergic effects. Choices B, C, and D are incorrect as indigestion, diarrhea, and pink urine are not commonly associated side effects of phenelzine.
4. A female client with severe depression who has been on antidepressants for two weeks suddenly becomes more energetic and talkative. What action should the RN take first?
- A. Encourage the client to participate in group activities.
- B. Monitor the client closely for signs of suicidal behavior.
- C. Praise the client for the apparent improvement.
- D. Discuss the client's progress with the healthcare provider.
Correct answer: B
Rationale: A sudden increase in energy and talkativeness in a client with severe depression who has been on antidepressants for a short period may indicate an increased risk of suicide due to the potential shift from profound sadness to motivation to act. The first action the RN should take is to monitor the client closely for signs of suicidal behavior. Encouraging participation in group activities or praising the client for the apparent improvement may overlook the potential risk of suicidal behavior. While discussing the client's progress with the healthcare provider is important, the immediate concern is to ensure the client's safety by closely monitoring for any signs of suicidal ideation or behavior.
5. When caring for a client who has overdosed on PCP, the nurse should be especially cautious about which of the following client behaviors?
- A. Visual hallucinations
- B. Violent behavior
- C. Bizarre behavior
- D. Loud screaming
Correct answer: B
Rationale: The correct answer is B: 'Violent behavior.' When a client has overdosed on PCP, the nurse should be particularly cautious about the manifestation of violent behavior. PCP overdose can lead to aggressive and unpredictable actions, posing a significant risk to both the client and healthcare providers. Visual hallucinations (choice A), bizarre behavior (choice C), and loud screaming (choice D) can also occur with PCP overdose, but the primary concern should be the potential for violent behavior, making it the most critical behavior to monitor and manage.
