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. The nurse should hold the next scheduled dose of a client's haloperidol (Haldol) based on which assessment finding(s)?
- A. Dizziness when standing.
- B. Shuffling gait and hand tremors.
- C. Urinary retention.
- D. Fever of 102°F.
Correct answer: D
Rationale: A fever (D) may indicate neuroleptic malignant syndrome (NMS), a potentially fatal complication of antipsychotics. The healthcare provider should be contacted before administering the next dose of Haldol. Dizziness when standing (A), shuffling gait and hand tremors (B), and urinary retention (C) are all adverse effects of Haldol that, while concerning, do not pose immediate life-threatening risks compared to the potential severity of NMS indicated by a fever.
3. A client with panic disorder is experiencing a panic attack. What is the nurse's priority intervention?
- A. Encourage the client to breathe slowly and deeply.
- B. Ask the client to describe the sensations they are experiencing.
- C. Encourage the client to focus on a calming image.
- D. Administer a PRN dose of lorazepam (Ativan).
Correct answer: A
Rationale: The correct answer is A. Encouraging slow, deep breathing is the priority intervention during a panic attack as it can help reduce the physiological symptoms and assist the client in regaining control. This technique can help decrease hyperventilation and promote relaxation. Choice B, asking the client to describe sensations, may be beneficial after the panic attack has subsided to gain insight into triggers or manifestations. Choice C, encouraging the client to focus on a calming image, can be helpful in managing anxiety but may not be as effective during the acute phase of a panic attack. Choice D, administering a PRN dose of lorazepam (Ativan), should only be considered if the client does not respond to initial non-pharmacological interventions or if the symptoms are severe and unmanageable.
4. A nurse is assessing a client with dementia who is showing signs of increased confusion and agitation in the late afternoon. What is the most likely explanation for the client's symptoms?
- A. Anxiety
- B. Depression
- C. Sun-downing syndrome
- D. Medication side effects
Correct answer: C
Rationale: The correct answer is C: Sun-downing syndrome. Sun-downing syndrome is a phenomenon commonly seen in individuals with dementia, where they exhibit increased confusion and agitation in the late afternoon or evening. This pattern of behavior is believed to be linked to disruptions in the circadian rhythm and can be triggered by factors such as fatigue, low lighting, or increased shadows during the evening. Choices A and B, anxiety and depression, may be comorbid conditions in individuals with dementia but are not the primary explanation for the symptoms described. While medication side effects (Choice D) should always be considered in a client with dementia, given the time-specific nature of the symptoms, sun-downing syndrome is the most likely explanation in this case.
5. An outpatient clinic that has been receiving haloperidol (Haldol) for 2 days develops muscular rigidity, altered consciousness, a temperature of 103, and trouble breathing on day 3. The LPN/LVN interprets these findings as indicating which of the following?
- A. Neuroleptic Malignant Syndrome
- B. Tardive dyskinesia
- C. Extrapyramidal adverse effects
- D. Drug-induced parkinsonism
Correct answer: A
Rationale: Neuroleptic Malignant Syndrome (NMS) is a life-threatening condition characterized by hyperthermia, muscle rigidity, altered consciousness, and autonomic dysregulation. It is a rare but serious side effect of antipsychotic medications like haloperidol (Haldol). NMS requires immediate intervention, including discontinuation of the offending medication and supportive care. Tardive dyskinesia (Choice B) is a different condition characterized by involuntary movements of the face and extremities that can occur with long-term antipsychotic use. Extrapyramidal adverse effects (Choice C) encompass a range of movement disorders like dystonia, akathisia, and parkinsonism that can result from antipsychotic medications, but they do not present with hyperthermia and altered consciousness as in NMS. Drug-induced parkinsonism (Choice D) is a form of parkinsonism caused by certain medications, but it typically presents with symptoms similar to Parkinson's disease, such as tremor, bradykinesia, and rigidity, without the severe hyperthermia and autonomic dysregulation seen in NMS.
