1. What are neurotransmitters?
- A. Chemical messengers that cause brain cells to turn on or off.
- B. Areas of the brain that are responsible for controlling emotions.
- C. Clumps of cells that alert the other brain cells to receive messages.
- D. Web-like structures that provide connections among parts of the brain.
Correct answer: A
Rationale: Neurotransmitters are chemicals in the brain that act as messengers between neurons, influencing various psychological functions. Choice A correctly defines neurotransmitters by stating that they are chemical messengers that cause brain cells to turn on or off. This is the function of neurotransmitters in transmitting signals between neurons. Choices B, C, and D are incorrect because they do not accurately describe neurotransmitters and their role in the brain.
2. A nurse working in the emergency room of a children's hospital admits a child whose injuries could have resulted from abuse. Which statement most accurately describes the nurse's responsibility in cases of suspected child abuse?
- A. Obtain objective data such as x-rays before reporting suspicions.
- B. Confirm suspicions of abuse with the physician.
- C. Report any case of suspected child abuse.
- D. Document injuries to confirm suspected abuse.
Correct answer: C
Rationale: The correct answer is C: 'Report any case of suspected child abuse.' Nurses are mandated reporters, which means they are legally obligated to report any suspicions of child abuse to appropriate authorities to ensure the child's safety. This responsibility overrides the need to gather additional data or confirm suspicions with others before reporting. Choice A is incorrect because delaying reporting to gather more data may risk the child's safety. Choice B is incorrect because reporting suspicions promptly is crucial, and waiting to confirm with another healthcare provider could delay necessary intervention. Choice D is incorrect as the priority is to report suspicions promptly rather than focusing on documenting injuries to confirm abuse.
3. A client with bipolar disorder is prescribed valproic acid (Depakote). What is the most important laboratory test for the LPN/LVN to monitor?
- A. Liver function tests.
- B. Kidney function tests.
- C. Thyroid function tests.
- D. Complete blood count.
Correct answer: A
Rationale: The correct answer is A: Liver function tests. Monitoring liver function tests is crucial for clients prescribed valproic acid (Depakote) due to the medication's potential to affect liver function and increase the risk of liver toxicity. While kidney function tests (choice B), thyroid function tests (choice C), and complete blood count (choice D) are important in various clinical scenarios, the priority when administering valproic acid is to monitor liver function to prevent adverse effects associated with this medication.
4. A moderately depressed client who was hospitalized 2 days ago suddenly begins smiling and reporting that the crisis is over. The client says to a nurse, 'I'm finally cured.' The LPN/LVN interprets this behavior as a cue to modify the treatment plan by:
- A. Suggesting a reduction of medication
- B. Allowing increased 'in-room' activities
- C. Increasing the level of suicide precautions
- D. Allowing the client off-unit privileges as needed
Correct answer: C
Rationale: A sudden improvement in mood and declaring being cured can be warning signs of a decision to attempt suicide. Therefore, the appropriate action would be to increase the level of suicide precautions to ensure the safety of the client. This can involve closer monitoring and restriction of items that could be harmful. Choices A, B, and D are incorrect as they do not address the potential risk of suicide that may be present with the sudden change in behavior.
5. A client with schizophrenia receiving haloperidol (Haldol) has a stiff, mask-like facial expression and difficulty speaking. What is the nurse's priority action?
- A. Administer a PRN dose of lorazepam (Ativan).
- B. Encourage the client to perform facial exercises.
- C. Notify the healthcare provider of possible extrapyramidal symptoms (EPS).
- D. Document the findings and continue to monitor the client.
Correct answer: C
Rationale: The correct answer is to notify the healthcare provider of possible extrapyramidal symptoms (EPS). The symptoms described, such as a stiff, mask-like facial expression and difficulty speaking, are indicative of EPS, which can be a serious side effect of haloperidol. It is crucial to involve the healthcare provider immediately to address these symptoms. Administering a PRN dose of lorazepam (Choice A) is not the priority in this situation, as it does not address the underlying cause of EPS. Encouraging the client to perform facial exercises (Choice B) is not appropriate and may not effectively manage EPS. Documenting the findings and continuing to monitor the client (Choice D) is important but not the priority when potential EPS is present; immediate action by notifying the healthcare provider is essential.
