Nokea
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?
- A. Explaining in depth what to expect during the upcoming procedure
- B. Administering a benzodiazepine medication prescribed for anxiety
- C. Taking a thorough history of her use of prescribed and illicit drugs
- D. Giving her a noncaffeinated beverage of her choice
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.

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?
- A. Smell
- B. Concept formation
- C. Receptive speech
- D. Hearing
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).
The nurse is caring for a patient who has experienced damage to the parietal lobes of the brain. The nurse anticipates that the patient will have difficulty with which of the following?
- A. Perceiving sensory input
- B. Calculating a math problem
- C. Seeing objects in front of him
- D. Speaking fluently
Correct Answer: A
Rationale: The parietal lobes process sensory information, such as touch and spatial awareness. Damage can impair sensory perception. Calculating math problems involves the frontal and parietal lobes but is less specific, seeing objects relates to the occipital lobe, and fluent speech involves Broca?s area.
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?
- A. Sleep deprivation EEG
- B. Polysomnography
- C. Evoked potentials
- D. Functional magnetic resonance imaging
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.
Which of the following would a nursing instructor identify when describing the area of the brain involved with verbal language function, including areas for both receptive and expressive speech?
- A. Right hemisphere
- B. Parietal lobe
- C. Occipital lobe
- D. Left hemisphere
Correct Answer: D
Rationale: The left hemisphere is primarily responsible for verbal language functions, including Broca?s area (expressive speech) and Wernicke?s area (receptive speech). The right hemisphere handles nonverbal functions, the parietal lobe processes sensory information, and the occipital lobe is involved in vision.
A nurse is teaching a medication class to a group of psychiatric patients. One of them asks the nurse why he has so much more trouble learning now when he?s in his 60s than he did when he was younger. Which of the following concepts would the nurse integrate into the response?
- A. The extrapyramidal motor system
- B. The amygdala
- C. Neuroplasticity
- D. Psychoneuroimmunology
Correct Answer: C
Rationale: Neuroplasticity refers to the brain?s ability to adapt and form new neural connections, which declines with age, impacting learning and memory. The nurse would explain that reduced neuroplasticity in older age makes learning more challenging. The extrapyramidal motor system affects movement, the amygdala regulates emotions, and psychoneuroimmunology involves immune-brain interactions, none of which directly address learning difficulties.
