A health-care provider prescribes computerized electroencephalography mapping for a client with suspected schizophrenia. Which statement made by the client accurately describes the procedure?

Correct Answer: A

Rationale: Step 1: Electroencephalography (EEG) mapping involves placing electrodes on the scalp. Step 2: The electrodes measure and mark electrical activity in the brain. Step 3: Schizophrenia is a mental disorder affecting brain function. Step 4: Therefore, the accurate statement is A, as it correctly describes the procedure for EEG mapping in detecting brain wave activity. Summary: B: X-rays are not used for EEG mapping; they are used for bone imaging. C: MRI (magnetic resonance imaging) is used for visualizing brain structure, not EEG mapping. D: Radioactive substances are not used in EEG mapping; they are used in imaging techniques like PET scans.

Correct Answer: C

Rationale: The correct answer is C: Severe anxiety. The client is showing extreme withdrawal, delusions, and emotional exhaustion, which are indicative of severe anxiety. Severe anxiety is characterized by intense emotional distress and impaired functioning. Mild anxiety (choice A) typically involves minimal impact on daily activities. Moderate anxiety (choice B) may cause some distress but does not result in delusions or extreme withdrawal. Panic anxiety (choice D) is characterized by overwhelming fear and physical symptoms, not necessarily delusions or emotional exhaustion.

Correct Answer: B

Rationale: The correct answer is B because Maslow's hierarchy of needs prioritizes safety needs, which include protection from harm and violence. In this scenario, a client exhibiting aggressive behavior toward another client poses an immediate threat to safety and requires immediate intervention. Choices A, C, and D relate to psychological and emotional needs, which are important but not as urgent as ensuring physical safety. A: Complaints about visiting hours can be addressed later. C: Feeling uncared for is important but does not pose an immediate danger. D: Feelings of failure should be explored and supported but do not require immediate intervention for safety.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Promoting client's sense of control and participation empowers them. 2. This can reduce anxiety and increase feelings of control over their pain. 3. By listening to concerns, you validate their feelings and build trust. 4. Empowering clients can positively impact their pain experience. Summary of Other Choices: A. Explaining interventions causing worry may increase anxiety. B. Giving medication on time is important but doesn't directly address psychological factors. C. Staying with the client during pain episodes provides comfort but doesn't address empowerment or control.

Correct Answer: C

Rationale: The correct answer is C because securing straps around the client's knees, ankles, and hands on an arm board is crucial for maintaining the client's safety during surgery. This helps prevent inadvertent movements that could lead to injury or interference with the surgical procedure. Straps made of strong, non-abrasive materials ensure comfort and proper positioning. A: The surgeon greeting the client before anesthesia induction is not directly related to maintaining the client's safety during surgery. B: The coordination between the surgeon and anesthesiologist is important but does not directly address the client's safety during the intraoperative phase. D: While monitoring by the assistant anesthesiologist is important, it is the responsibility of the circulating nurse to ensure physical safety measures are in place.
