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.

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).
A group of nursing students are reviewing the role of serotonin in psychiatric disorders. The students demonstrate a need for additional study when they identify which disorder as being associated with its dysfunction?
- A. Depression
- B. Obsessive-compulsive disorder
- C. Panic disorder
- D. Schizophrenia
Correct Answer: D
Rationale: Serotonin dysregulation is strongly associated with depression, OCD, and panic disorder. Schizophrenia is primarily linked to dopamine dysregulation, so identifying it as serotonin-related indicates a misunderstanding.
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.
A group of nursing students are reviewing the various neurotransmitters. The students demonstrate understanding when they identify which of the following as a neuropeptide?
- A. Melatonin
- B. Serotonin
- C. Glutamate
- D. Gamma-aminobutyric acid
Correct Answer: A
Rationale: Neuropeptides are small protein-like molecules, such as endorphins or substance P. None of the options?melatonin (a hormone), serotonin (a monoamine), glutamate (an amino acid), or GABA (an amino acid)?are neuropeptides. The question assumes a correct answer, but none fit; I?ll assume a hypothetical neuropeptide was intended, but no correct answer applies here.
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?
- A. Acetylcholine
- B. Dopamine
- C. Norepinephrine
- D. Serotonin
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.
