A client is scheduled to complete a positron emission tomography (PET) scan. The client asks the nurse to explain the reason the test was prescribed. How should the nurse respond?
- A. Images indicate the presence of tumors and scars.
- B. The scan clearly outlines structures of the brain.
- C. Results show activity in various portions of the brain.
- D. PET shows biochemical levels of neurotransmitters.
Correct Answer: C
Rationale: The correct answer is C. PET scans are primarily used to detect and observe the metabolic activity in various parts of the brain. This helps in diagnosing conditions related to brain function, such as tumors, brain disorders, and overall brain activity. Choices A, B, and D are incorrect because PET scans focus on metabolic activity and functions in the brain rather than solely indicating the presence of tumors, outlining brain structures, or showing biochemical levels of neurotransmitters.

An older female adult who lives in a nursing home is loudly demanding that the nurse call her son who has been deceased for five years. Which intervention should the nurse implement?
- A. Assist the client in making the phone call.
- B. Remind the client about her son's passing.
- C. Escort the client to a private area.
- D. Direct the client to a new activity.
Correct Answer: D
Rationale: In this situation, the most appropriate intervention is to direct the client to a new activity. This approach can help redirect the client's attention, distract her from the distressing request, and engage her in a more positive interaction. Choice A could exacerbate the client's distress by attempting to make the impossible call, and reminding the client about her son's passing (Choice B) may increase her emotional distress. Escorting the client to a private area (Choice C) does not address the underlying issue and may not effectively manage the situation.
The community health nurse talks to a male client who has bipolar disorder. The client explains that he sleeps 4 to 5 hours a night and is working with his partner to start two new businesses and build an empire. The client stopped taking his medications several days ago. What nursing problem has the highest priority?
- A. Excessive work activity.
- B. Decreased need for sleep.
- C. Medication management.
- D. Inflated self-esteem.
Correct Answer: D
Rationale: The priority is to manage the client's medication adherence to prevent escalation of manic behavior. Inflated self-esteem is the highest priority as it indicates the client's potential for harmful behaviors due to lack of medication compliance. While excessive work activity and decreased need for sleep are characteristics of mania, they are not as immediately concerning as the risk of harm related to inflated self-esteem.
An anxious client expressing a fear of people and open places is admitted to the psychiatric unit. What is the most effective way for the nurse to assist this client?
- A. Plan an outing within the second week of admission.
- B. Distract the client whenever they express discomfort about being with others.
- C. Confront the client's fears and discuss the possible causes of these fears.
- D. Accompany the client outside for an increasing amount of time each day.
Correct Answer: D
Rationale: The most effective way to assist a client with a fear of people and open places is through gradual desensitization by controlled exposure to the situation which is feared (D). This method helps the client confront their fears in a safe and supportive manner, allowing them to gradually build confidence and reduce anxiety. Planning an outing within the second week of admission (A) may be too soon and overwhelming for the client. Distracting the client whenever they express discomfort (B) does not address the underlying issue and may promote denial. Confronting the client's fears and discussing possible causes (C) could be too aggressive initially and may not be well-tolerated by the client.
An adolescent with major depressive disorder has been taking duloxetine (Cymbalta) for the past 12 days. Which assessment finding requires immediate follow-up?
- A. Describes life as without purpose.
- B. Exhibits an increase in sweating.
- C. States is often fatigued and drowsy.
- D. Complains of nausea and loss of appetite.
Correct Answer: A
Rationale: The correct answer is A. Expressing that life is without purpose can indicate deepening depression or suicidal ideation, which requires immediate attention. While sweating, fatigue, drowsiness, nausea, and loss of appetite can be side effects of duloxetine (Cymbalta), they do not indicate the same level of urgency as a statement suggesting deepening depression or suicidal ideation.
A client who has been diagnosed with borderline personality disorder is exhibiting manipulative behavior. What is the most important intervention for the LPN/LVN to implement?
- A. Set clear, consistent limits on manipulative behavior.
- B. Ignore the manipulative behavior to avoid reinforcing it.
- C. Remind the client that manipulative behavior is unacceptable.
- D. Explain the consequences of manipulative behavior to the client.
Correct Answer: A
Rationale: Setting clear, consistent limits on manipulative behavior is the most important intervention for a client diagnosed with borderline personality disorder. This approach helps establish boundaries, maintain a therapeutic environment, and provide structure for the client. Choice B is incorrect because ignoring manipulative behavior can lead to its reinforcement. Choice C, while important, may not be as effective as directly setting limits. Choice D focuses on consequences rather than immediate intervention, making it less effective than setting clear limits.
