A nurse would expect that an increase in dopamine activity might play a significant role in the development of which mental illness?

Correct Answer: A

Rationale: An increase in dopamine activity is associated with positive symptoms of schizophrenia, such as hallucinations and delusions. Dopamine dysregulation hypothesis posits that excess dopamine transmission contributes to schizophrenia symptoms. This is why choice A, Schizophrenia spectrum disorder, is the correct answer. In contrast, major depressive disorder is associated with low levels of serotonin and norepinephrine, not dopamine (choice B). Tourette syndrome is linked to abnormalities in dopamine and other neurotransmitters, but not exclusively dopamine (choice C). Parkinson's disease is characterized by a decrease, not an increase, in dopamine due to the degeneration of dopaminergic neurons in the brain (choice D).

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.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. Verify the flow rate against your computation: This is crucial to ensure the correct dosage is being administered and prevents overdosage. 2. Checking the functionality of the pump before use (Option A) is important, but directly verifying the flow rate is more specific and critical for safety. 3. Selecting a brand of infusion pump (Option B) is irrelevant to the actual safety procedures of using the pump. 4. Allowing the technician to set the pump (Option C) may lead to errors if the settings are not double-checked by the staff administering the medication.
