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 client with bipolar disorder is being treated with lithium. The nurse should monitor the client for which early sign of lithium toxicity?

A. Diarrhea
B. Tremors
C. Polyuria
D. Blurred vision

Correct answer: A

Rationale: Corrected Rationale: Diarrhea is an early sign of lithium toxicity. When a client being treated with lithium presents with diarrhea, it can indicate the beginning of lithium toxicity. Monitoring for this symptom is crucial as it can progress to more severe toxicity if not addressed promptly. Tremors (choice B) are more commonly associated with the therapeutic effects of lithium rather than toxicity. Polyuria (choice C) is a common side effect of lithium, but it is not typically an early sign of toxicity. Blurred vision (choice D) is not a common early sign of lithium toxicity. Therefore, option A is the correct answer.

3. Physical examination of a 6-year-old reveals several bite marks in various locations on his body. X-ray examination reveals healed fractures of the ribs. The mother tells the nurse that her child is always having accidents. Which initial response by the nurse is most appropriate?

A. I need to inform the healthcare provider about your child's tendency to be accident-prone.
B. Tell me more specifically about your child's accidents.
C. I must report these injuries to the authorities because they do not seem accidental.
D. Boys this age always seem to require more supervision and can be quite accident-prone.

Correct answer: B

Rationale: (B) seeks more information in a non-threatening manner to gather additional details about the child's accidents. This response allows the nurse to explore the situation further without making assumptions. (A) fails to address the concerning findings and instead focuses on informing the healthcare provider. (C) jumps to conclusions without gathering more information, potentially causing unnecessary distress to the family. (D) dismisses the seriousness of the situation by attributing the injuries to common accidents for boys, missing the opportunity to delve deeper into the issue.

4. A client with post-traumatic stress disorder (PTSD) is experiencing a flashback. What is the nurse's priority action?

A. Encourage the client to talk about the trauma.
B. Help the client to focus on the present.
C. Administer prescribed anti-anxiety medication.
D. Leave the client alone to work through the flashback.

Correct answer: B

Rationale: The priority action is to help the client focus on the present (B), which can reduce the intensity of the flashback. Encouraging discussion of the trauma (A) should be done when the client is not actively experiencing a flashback. While medication (C) may be necessary, it is not the first priority in this situation. Leaving the client alone (D) is not appropriate as they need support to manage the flashback.

5. When a client with schizophrenia is being discharged on antipsychotic medication, what is the most important instruction the nurse should provide?

A. Stop the medication if you start feeling better.
B. Be aware of the potential for weight gain with this medication.
C. Report any unusual muscle movements immediately.
D. You can drive as soon as you feel ready.

Correct answer: C

Rationale: The correct answer is to instruct the client to report any unusual muscle movements immediately. These movements may indicate extrapyramidal symptoms (EPS) or tardive dyskinesia, which are serious side effects of antipsychotic medications that require immediate attention. Choice A is incorrect because stopping the medication without medical advice can lead to a relapse of symptoms. Choice B is important but not as critical as monitoring for EPS. Choice D is incorrect because driving readiness is not directly related to antipsychotic medication instructions.
