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. What assessment is the priority focus for a client with major depression?
- A. Mood and affect.
- B. Suicidal ideation.
- C. Nutritional status.
- D. Fluid and electrolyte balance.
Correct answer: B
Rationale: The correct answer is B: Suicidal ideation. When dealing with a client diagnosed with major depression, assessing for suicidal ideation is of utmost importance. Individuals with major depression have an increased risk of suicide; hence, evaluating their risk for self-harm is crucial. Mood and affect, while important, come secondary to ensuring the safety of the client. Nutritional status and fluid and electrolyte balance are essential components of care but are not the priority when dealing with a client with major depression.
3. A male employee who is assessed weekly in the employee clinic for blood pressure because of a history of hypertension tells the nurse that he is so upset with one of his co-workers that he would like to shoot him. What action should the nurse take first?
- A. Determine if the client has a weapon available for use.
- B. Inform the health care provider of the threat to harm a co-worker.
- C. Notify security of the client's intention to harm a co-worker.
- D. Have the employee escorted to a mental health facility.
Correct answer: A
Rationale: Determining if the client has access to a weapon is critical for immediate safety and to prevent potential harm.
4. A client with an eating disorder is planning to attend group meetings with Overeaters Anonymous. The LPN/LVN describes this group to the client, knowing that which finding(s) are characteristic of this form of self-help group? Select one that does not apply.
- A. A common goal is shared by all members
- B. Members are required to remain anonymous
- C. The leader is a professional mental health care provider
- D. Attendance must be prescribed by the health care provider
Correct answer: A
Rationale: Overeaters Anonymous is a self-help group characterized by shared goals among members to address eating disorders. This provides a supportive environment for personal change and growth. Choice B is incorrect as members are not required to remain anonymous in Overeaters Anonymous. Choice C is incorrect as the leader in such self-help groups is usually a member who has experienced similar issues, not necessarily a professional mental health care provider. Choice D is incorrect as attendance at Overeaters Anonymous meetings is voluntary and not prescribed by a healthcare provider.
5. A woman brings her 48-year-old husband to the outpatient psychiatric unit and describes his behavior to the admitting nurse. She states that he has been sleepwalking, cannot remember who he is, and exhibits multiple personalities. The nurse knows that these behaviors are often associated with
- A. dissociative disorder.
- B. obsessive-compulsive disorder.
- C. panic disorder.
- D. post-traumatic stress disorder.
Correct answer: A
Rationale: The correct answer is A: dissociative disorder. Sleepwalking, amnesia, and multiple personalities are examples of detaching emotional conflict from one's consciousness, which is the definition of a dissociative disorder. Obsessive-compulsive disorder (B) is characterized by persistent, recurrent intrusive thoughts or urges (obsessions) and compulsions. Panic disorder (C) is characterized by acute attacks of anxiety. Post-traumatic stress disorder (D) involves re-experiencing psychologically distressing events.
