1. Which neurotransmitter is most closely associated with mood regulation and is targeted by antidepressants?

• A. Serotonin
• B. Dopamine
• C. GABA
• D. Acetylcholine

Correct answer: A

Rationale: The correct answer is A: Serotonin. Serotonin plays a vital role in mood regulation, and its imbalance is often associated with depression. Many antidepressants function by boosting serotonin levels in the brain. Dopamine (Choice B) is more linked to reward and pleasure pathways in the brain, not primarily targeted for mood regulation. GABA (Choice C) is an inhibitory neurotransmitter that helps reduce neuronal excitability, not primarily associated with mood regulation. Acetylcholine (Choice D) is involved in muscle movement and cognitive functions, not the primary target of antidepressants for mood regulation.

2. A nurse who receives a patient in the operative suite prior to the actual surgery is in charge of the patient’s care. Which of the following is NOT a task related to the nurse’s intraoperative care?

• A. Go over the surgical procedure with the patient before he or she is anesthetized
• B. Strictly adhere to asepsis during all intraoperative procedures
• C. Provide emotional support to the patient and their family
• D. Monitor the patient’s physical status

Correct answer: A

Rationale: The correct answer is A. Going over the surgical procedure with the patient is typically done preoperatively, not intraoperatively. Intraoperative tasks of a nurse involve strictly adhering to asepsis during procedures, monitoring the patient's physical status, and providing emotional support to the patient and their family during the surgery. Choices B, C, and D are all tasks that are directly related to the nurse's responsibilities during the intraoperative phase of care.

3. All of the following are posture and body alignment problems EXCEPT:

• A. Kyphosis
• B. Scoliosis
• C. Thrombosis
• D. Lumbar lordosis

Correct answer: C

Rationale: Thrombosis is a condition involving blood clots and is not related to posture or body alignment, unlike kyphosis, scoliosis, and lumbar lordosis, which are spinal alignment issues. Kyphosis refers to excessive outward curvature of the spine, scoliosis is characterized by a sideways curvature of the spine, and lumbar lordosis involves an exaggerated inward curve in the lower back. Thrombosis, on the other hand, is a condition where blood clots form in the blood vessels, not a posture or body alignment problem.

4. Which condition is commonly screened for in newborns using the Guthrie test?

• A. Phenylketonuria (PKU)
• B. Cystic fibrosis
• C. Down syndrome
• D. Sickle cell anemia

Correct answer: A

Rationale: The Guthrie test is specifically designed to screen newborns for phenylketonuria (PKU), a metabolic disorder that can lead to intellectual disability if left untreated. Phenylketonuria is caused by the deficiency of an enzyme required to metabolize the amino acid phenylalanine. Screening for PKU in newborns is crucial as early diagnosis and intervention can prevent the severe consequences associated with the condition. Choices B, C, and D are incorrect as the Guthrie test is not used to screen for cystic fibrosis, Down syndrome, or sickle cell anemia.

5. A client is admitted to the postoperative surgical unit with two test tubes after a left lobectomy. The nurse observed that the chambers are set at the prescribed suction of 20 cm water pressure, and tidying occurs with respirations and bubbling. What action should the nurse implement?

• A. Clamp the chest tube to see if the bubbling activity stops
• B. Notify the registered nurse of the observed bubbling
• C. Maintain system integrity to promote lung reexpansion
• D. Apply an occlusive dressing to the chest

Correct answer: C

Rationale: Maintaining system integrity is essential to promote lung reexpansion in postoperative patients with chest tubes. Clamping the chest tube abruptly can lead to tension pneumothorax, a life-threatening condition. The bubbling observed is a normal sign indicating that the system is functioning correctly, as it allows the drainage of air or fluid from the pleural space. Notifying the registered nurse may be necessary if there are significant concerns or changes observed, but the immediate action should be to ensure system integrity and lung reexpansion.
