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. The nurse observes a client who is admitted to the mental health unit and identifies that the client is talking continuously, using words that rhyme but that have no context or relationship with one topic to the next in the conversation. This client's behavior and thought processes are consistent with which syndrome?

• A. Dementia
• B. Depression
• C. Schizophrenia
• D. Chronic brain syndrome

Correct answer: C

Rationale: The client is demonstrating symptoms of schizophrenia, such as disorganized speech that may include word salad (a type of communication that mixes real and imaginary words in no logical order), incoherent speech, and clanging (rhyming). Dementia (Choice A) is characterized by memory loss and cognitive decline, not by disorganized speech. Depression (Choice B) typically presents with persistent feelings of sadness and loss of interest, not disorganized speech. Chronic brain syndrome (Choice D) is a vague term and does not specifically describe the symptoms mentioned in the scenario.

3. A client with schizophrenia is admitted to the psychiatric care unit for aggressive behavior, auditory hallucinations, and potential for self-harm. The client has not been taking medications as prescribed and insists that the food has been poisoned and refuses to eat. What intervention should the RN implement?

• A. Assure the client that all food served in the hospital is safe to eat.
• B. Tell the client that irrational thinking is a symptom of schizophrenia.
• C. Obtain an order for a tube feeding for the client.
• D. Provide the client with food in unopened containers.

Correct answer: D

Rationale: The correct intervention is to provide the client with food in unopened containers. This approach can help alleviate the client's fear of poisoning and encourage eating. Choice A may not address the client's specific fear and may be perceived as dismissive. Choice B, while providing information about symptoms of schizophrenia, does not address the immediate issue of the client's refusal to eat due to the fear of poisoning. Choice C of obtaining an order for tube feeding is premature and invasive before exploring less restrictive options.

4. 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.

5. An elderly female client with advanced dementia is admitted to the hospital with a fractured hip. The client repeatedly tells the staff, 'Take me home. I want my Mommy.' Which response is best for the nurse to provide?

• A. Orient the client to the time, place, and person.
• B. Tell the client that the nurse is there and will help her.
• C. Remind the client that her mother is no longer living.
• D. Explain the seriousness of her injury and need for hospitalization.

Correct answer: B

Rationale: Those with dementia often refer to home or parents when seeking security and comfort. The nurse should use the techniques of 'offering self' and 'talking to the feelings' to provide reassurance (B). Clients with advanced dementia have permanent physiological changes in the brain (plaques and tangles) that prevent them from comprehending and retaining new information, so choices A, C, and D are likely to be of little use to this client and do not address the emotional needs expressed by the client. Option B acknowledges the client's feelings, offers support, and provides reassurance, which can help comfort the client during this distressing time.
