HESI Mental Health Practice Exam

Correct Answer: A

Rationale: The correct answer is A: Liver function tests. Valproic acid can cause hepatotoxicity, leading to liver damage. Monitoring liver function tests is crucial to detect any early signs of liver impairment. Kidney function tests (Choice B) are not the most important to monitor in this case. Blood glucose levels (Choice C) and serum sodium levels (Choice D) are not directly affected by valproic acid and are not the priority for monitoring in a client taking this medication.

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.

Correct Answer: A

Rationale: When a client is guarded, suspicious, and resistant to talking, it is important for the nurse to attempt to ask the client simple questions. Simple questions can help build rapport, establish trust, and create a non-threatening environment. This approach may ease the client into more detailed discussions while reducing feelings of suspicion. Postponing the interview may increase the client's anxiety and distrust, while asking another nurse to talk with the client may disrupt continuity of care and the establishment of a therapeutic relationship. Documenting the client's behavior is important for the client's medical record, but it should not be the first action taken in this situation.

Correct Answer: C

Rationale: Teaching the client that the medication may take 4 to 6 weeks to become fully effective is crucial as it helps set realistic expectations. While choice A is important to reduce nausea, it is not the most critical information to provide initially. Choice B is incorrect as improvement usually occurs after several weeks of treatment, not within 1 to 2 weeks. Choice D is also relevant, but informing about the full effectiveness of the medication is more important for long-term adherence.

Correct Answer: D

Rationale: The correct answer is D: Flat affect. Flat affect, which is a lack of emotional expression, is highly characteristic of schizophrenia. Mood swings (choice A) are more indicative of mood disorders rather than schizophrenia. Extreme sadness (choice B) could be seen in depression but is not as specific to schizophrenia. Manipulative behavior (choice C) is not a defining characteristic of schizophrenia; it may be seen in various psychiatric conditions but is not the most characteristic feature of schizophrenia.
