A client diagnosed with schizophrenia is experiencing frequent hallucinations. What altered component of the nervous system would a nurse recognize as being responsible for this behavior?

Correct Answer: C

Rationale: The correct answer is C: Increase in dopamine. In schizophrenia, an increase in dopamine levels in certain areas of the brain is associated with the development of hallucinations. Dopamine is a neurotransmitter that plays a key role in regulating mood, reward, and movement. Excess dopamine activity in the brain can lead to distorted perceptions and hallucinations. Serotonin (Choice A) is more related to mood regulation, histamine (Choice B) is not directly involved in hallucinations in schizophrenia, and acetylcholine (Choice D) is associated with cognitive function and memory, not hallucinations in schizophrenia.

Correct Answer: B

Rationale: The correct answer is B because individuals experiencing psychoses often have a distorted perception of reality, leading to significant distress. They may have hallucinations, delusions, or disorganized thoughts, causing emotional turmoil. Choice A is incorrect as individuals with psychosis may lack insight into their behaviors. Choice C is incorrect because individuals with psychosis may not fully recognize their psychological problems. Choice D is incorrect because psychosis involves a disconnect from reality, leading to a lack of grounding in actuality.

Correct Answer: D

Rationale: The correct answer is D, the Pathology department. They are responsible for blood banking and transfusion services. They coordinate closely with the patient's family for immediate blood component therapy in cases of massive blood loss. Security Division (A) ensures safety, Chaplaincy (B) provides spiritual support, and Social Service Section (C) assists with social needs, but they do not directly handle blood component therapy coordination in this scenario.

Correct Answer: D

Rationale: The correct answer is D, Medical records section. This is because the medical records section is responsible for maintaining and storing all patient records, including previous charts. Requesting the old chart from the medical records section ensures accuracy and completeness of the client's medical history. A: Central supply section - Incorrect, as this department is responsible for providing medical supplies and equipment, not maintaining patient records. B: Previous doctor's clinic - Incorrect, as the clinic may not have the complete medical history if the patient has been seen in multiple departments. C: Department where the patient was previously admitted - Incorrect, as they may not have access to the complete medical records from other departments.

Correct Answer: C

Rationale: The correct answer is C: Clipped. Clipping the hair at the operative site is crucial as it reduces the risk of infection by minimizing bacteria harboring in hair follicles. It also makes suturing easier by providing a clean and clear surgical field. Draping (A) refers to covering the patient with a sterile sheet, which is important but not directly related to hair removal. Pulling (B) can cause trauma to the skin and increase infection risk. Shampooing (D) is not necessary for hair removal before surgery and may not effectively remove hair from the operative site.
