Nursing Elites

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. 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.

3. The charge nurse is collaborating with the nursing staff about the plan of care for a client who is very depressed. What is the most important intervention to implement during the first 48 hours after the client's admission to the unit?

• A. Monitor appetite and observe intake during meals.
• B. Maintain safety in the client's environment.
• C. Provide ongoing, supportive contact.
• D. Encourage participation in activities.

Correct answer: B

Rationale: The most critical intervention to implement during the first 48 hours after admitting a depressed client is to maintain safety (B). Depression increases the risk of suicide; hence ensuring a safe environment is the priority. While monitoring appetite (A), providing supportive contact (C), and encouraging participation in activities (D) are important aspects of care for a depressed client, ensuring safety takes precedence in the initial phase of admission.

4. A client with major depressive disorder is started on fluoxetine (Prozac). What should the nurse include in the client's discharge teaching?

• A. It may take 4-6 weeks for the medication to be effective.
• B. You should take this medication at bedtime.
• C. Avoid consuming dairy products while taking this medication.
• D. You can stop taking the medication once you feel better.

Correct answer: A

Rationale: The correct answer is A: "It may take 4-6 weeks for the medication to be effective." SSRIs like fluoxetine typically take 4-6 weeks to reach their full effect, so clients should be informed to expect a gradual improvement in symptoms. Choice B is incorrect because fluoxetine is usually taken in the morning to prevent sleep disturbances. Choice C is incorrect as there is no specific need to avoid consuming dairy products while taking fluoxetine. Choice D is incorrect because clients should never stop taking antidepressants abruptly, as it can lead to withdrawal symptoms and worsening of the condition.

5. An older homeless client visits the psychiatric clinic to obtain a prescription renewal for alprazolam (Xanax). During the health assessment, the client complains of chest pain. Which action should the RN take first?

• A. Refer the client to the cardiology unit.
• B. Obtain the client's blood pressure.
• C. Assess the client for substance abuse.
• D. Determine if Xanax was taken recently.

Correct answer: D

Rationale: Determining if Xanax was taken recently is crucial as it helps assess whether the chest pain is related to medication use or another issue, guiding appropriate immediate care. This action can provide essential information to address the client's current complaint effectively. Referring the client to the cardiology unit (Choice A) may be premature without assessing the Xanax use first. While obtaining the client's blood pressure (Choice B) is important, it is not the priority when the client presents with chest pain and a history of taking Xanax. Assessing the client for substance abuse (Choice C) is also important but is secondary to first determining the potential link between Xanax and the chest pain.
