Chapter 8 Questions
Question 1 of 5
A nurse is developing a plan of care for a patient diagnosed with schizophrenia. The nurse integrates knowledge of this disorder, identifying which neurotransmitter as being primarily involved?
Correct Answer: B
Rationale: Schizophrenia is primarily associated with dopamine dysregulation, particularly in the mesolimbic pathway, contributing to symptoms like hallucinations. Acetylcholine, norepinephrine, and serotonin play roles in other disorders but are not primary in schizophrenia.
Question 2 of 5
A patient with depression tells the nurse that he is to have a test that involves the recording of an electroencephalogram (EEG) throughout the night. The nurse most likely identifies this testing as which of the following?
Correct Answer: B
Rationale: Polysomnography involves overnight EEG recording to assess sleep patterns, often used in depression to evaluate sleep disturbances. Sleep deprivation EEG requires staying awake, evoked potentials test sensory responses, and fMRI measures brain activity, not sleep.
Question 3 of 5
The nurse is caring for an older adult who has experienced damage to the frontal lobe after an automobile accident. The nurse anticipates that the patient will have difficulty with which of the following?
Correct Answer: B
Rationale: The frontal lobe is responsible for executive functions, including concept formation, planning, and decision-making. Damage may impair these abilities. Smell is associated with the olfactory bulb, receptive speech with Wernicke?s area (temporal lobe), and hearing with the auditory cortex (temporal lobe).
Question 4 of 5
A patient who is scheduled to undergo a sleep deprivation electroencephalogram (EEG) in the morning is experiencing moderate anxiety about the procedure. Based on an understanding of this test, which of the following would the nurse avoid?
Correct Answer: B
Rationale: A sleep deprivation EEG requires the patient to stay awake to provoke brain activity for diagnosis. Administering a benzodiazepine, which promotes sedation, would counteract this purpose. Explaining the procedure, taking a history, and offering a noncaffeinated beverage are appropriate and support the test?s goals.
Question 5 of 5
A nursing instructor asks a student to explain the influence of chronobiology on depression. Which of the following would the student include when responding?
Correct Answer: D
Rationale: Chronobiology studies biological rhythms, such as circadian rhythms, which influence mood disorders like depression. Internal (e.g., hormonal changes) and external (e.g., light exposure) triggers can disrupt these rhythms, contributing to depressive symptoms. The other options relate to genetics, brain connectivity, or sensory function, not chronobiology.
