HESI Mental Health Practice Questions
1. A nurse working in a psychiatric unit is assessing a client who appears to be responding to internal stimuli. The client is laughing and talking to himself. What is the nurse's best initial response?
- A. Approach the client and ask if he is hearing voices.
- B. Ignore the behavior as it is common in psychiatric settings.
- C. Encourage the client to express his thoughts verbally.
- D. Observe the client's behavior from a distance.
Correct answer: A
Rationale: Approaching the client and asking if he is hearing voices is the best initial response by the nurse. This action can help assess the situation and determine if the client is experiencing hallucinations that may require immediate intervention. Choice B is incorrect because ignoring the behavior could lead to missing important signs of distress or potential risks. Choice C may not address the immediate concern of assessing for hallucinations. Choice D is also not ideal as observing from a distance may not provide the necessary information for immediate assessment and intervention.
2. A client with schizophrenia is being treated with clozapine (Clozaril). What laboratory test is most important for the nurse to monitor?
- A. Liver function tests
- B. Kidney function tests
- C. White blood cell count
- D. Blood glucose levels
Correct answer: C
Rationale: The correct answer is C: White blood cell count. Clozapine can lead to agranulocytosis, a severe drop in white blood cells, which can be life-threatening. Monitoring the white blood cell count is crucial to detect this condition early. Choices A, B, and D are incorrect because while liver and kidney function tests are important in monitoring other aspects of health, the most critical concern with clozapine therapy is the risk of agranulocytosis, making monitoring white blood cell count the priority.
3. A client with a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management asks how it works. What information should the nurse reinforce?
- A. The discharge of electricity will distract the client's focus from the pain
- B. An infusion of medication in the spinal canal will block pain perception
- C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
- D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
Correct answer: D
Rationale: The correct answer is D. TENS works by delivering a mild electrical stimulus that can block pain signals from reaching the brain, effectively reducing the perception of pain. Choice A is incorrect because TENS does not distract from pain but rather interferes with pain signals. Choice B is incorrect as TENS does not involve infusing medication into the spinal canal. Choice C is also incorrect because TENS does not target the cerebral cortex to dull pain perception but rather works at the level of nerve conduction.
4. A female client in an acute care facility has been on antipsychotic medications for the past three days. Her psychotic behaviors have decreased and she has had no adverse reactions. On the fourth day, the client's blood pressure increases, she becomes pale and febrile, and demonstrates muscular rigidity. What action should the nurse initiate?
- A. Place the client on seizure precautions and monitor her frequently.
- B. Take the client's vital signs and notify the physician immediately.
- C. Describe the symptoms to the charge nurse and document them in the client's record.
- D. No action is required at this time as these are known side effects of her medications.
Correct answer: B
Rationale: The correct action for the nurse to initiate is to take the client's vital signs and notify the physician immediately. These symptoms may indicate neuroleptic malignant syndrome, a rare but life-threatening reaction to antipsychotic medications, requiring immediate medical attention. Placing the client on seizure precautions and monitoring her frequently (Choice A) is not the most appropriate action in this situation. Describing the symptoms to the charge nurse and documenting them in the client's record (Choice C) delays prompt medical intervention. Choosing not to take any action (Choice D) is dangerous as the symptoms described suggest a serious condition that needs urgent evaluation and treatment.
5. A new mother is at the clinic with her 4-week-old for a well-baby check-up. The nurse should tell the mother to anticipate that the infant will demonstrate which milestone by 2 months of age?
- A. Turns from side to back and returns
- B. Consistently returns smiles to mother
- C. Finds hands and plays with fingers
- D. Holds head up and supports weight with arms
Correct answer: B
Rationale: The correct answer is B because social smiling is a developmental milestone typically expected around 2 months of age. At this stage, infants start to engage more with their caregivers and show positive emotional responses. The other choices are incorrect. Choice A describes a motor skill that usually emerges later. Choice C involves more coordination and exploration, which is not typically seen by 2 months. Choice D relates to head control and arm strength, which also develop progressively but may not be fully achieved by 2 months.
