The PMHNP works on an inpatient geriatric psychiatric unit. She knows that which of the following features is commonly present in Lewy body dementia?
A. A steadily progressive, gradual decline in reasoning and increased incidence of sleepwalking
This choice is incorrect because Lewy body dementia does involve cognitive decline, but sleepwalking is not a characteristic feature. The hallmark symptoms include fluctuating cognition, visual hallucinations, and parkinsonism.
B. Motor abnormalities with a low incidence of depression and psychosis
This choice is incorrect because Lewy body dementia is associated with both motor abnormalities and a higher risk of psychiatric symptoms, including depression and hallucinations, not a low incidence of these.
C. Recurrent visual hallucinations; affected patients adversely react to antipsychotics
This choice is correct because recurrent visual hallucinations and sensitivity to antipsychotic medications are hallmark features of Lewy body dementia. Patients often have parkinsonian motor symptoms and can deteriorate rapidly when exposed to antipsychotics.
D. A slowly progressive and fatal disorder that manifests with depression, psychosis, personality changes, and dementia
This choice is partially correct in describing some aspects of dementia but is more representative of Alzheimer’s disease or other neurodegenerative disorders. It does not capture the specific hallmark features of Lewy body dementia.

Full Explanation
Choice A reason: This choice is incorrect because Lewy body dementia does involve cognitive decline, but sleepwalking is not a characteristic feature. The hallmark symptoms include fluctuating cognition, visual hallucinations, and parkinsonism.
Choice B reason: This choice is incorrect because Lewy body dementia is associated with both motor abnormalities and a higher risk of psychiatric symptoms, including depression and hallucinations, not a low incidence of these.
Choice C reason: This choice is correct because recurrent visual hallucinations and sensitivity to antipsychotic medications are hallmark features of Lewy body dementia. Patients often have parkinsonian motor symptoms and can deteriorate rapidly when exposed to antipsychotics.
Choice D reason: This choice is partially correct in describing some aspects of dementia but is more representative of Alzheimer’s disease or other neurodegenerative disorders. It does not capture the specific hallmark features of Lewy body dementia.
Similar Questions
An urgent care nurse practitioner comes in to examine his patient, a 77-year-old woman who was brought in by her family for altered mental status. He notes that the patient appears restless and does not know where she is. Upon further assessment, he notes that her pupils are sluggish to react to light and are unequal in size. She is unable to sit up at the side of the bed and her blood pressure is 190/88 mm Hg. Which of the following does the NP suspect?
A. Ischemic stroke
Ischemic stroke may present with focal neurological deficits, but the combination of unequal pupils, inability to sit up, and high blood pressure suggests a more global intracranial process rather than a localized ischemic event.
B. Increased intracranial pressure
This choice is correct because the patient’s altered mental status, unequal and sluggish pupils, postural instability, and elevated blood pressure are classic signs of increased intracranial pressure. These findings suggest a critical neurological emergency.
C. Myocardial infarction
Myocardial infarction typically presents with chest pain, shortness of breath, and cardiovascular symptoms rather than altered mental status and pupil abnormalities.
D. Cerebral aneurysm
Cerebral aneurysm rupture can cause acute neurological decline, but unequal pupils and gradually increasing blood pressure are more consistent with generalized intracranial pressure rather than the sudden presentation of a subarachnoid hemorrhage.

The area of the brain that is responsible for speech, cognition, judgment, perception, and motor function is:
A. The cerebellum
The cerebellum primarily regulates coordination, balance, and fine motor control, not higher cognitive functions or judgment.
B. The medulla oblongata
The medulla oblongata controls autonomic functions such as breathing, heart rate, and reflexes, rather than cognition or speech.
C. The cerebral cortex
This choice is correct because the cerebral cortex is the outer layer of the brain responsible for higher-order functions, including reasoning, perception, language, voluntary motor activity, and decision-making.
D. The hypothalamus
The hypothalamus regulates homeostatic functions such as temperature, hunger, thirst, and endocrine control, but does not directly control cognition, speech, or judgment.

A 10-year-old boy displays deficits in intellectual functions that involve his ability to reason, solve problems, and learn from instruction or experience. He has been slow to develop skills in school and is behind his peers in reading, writing, and mathematical abilities. As a result, he has significant impairments in his ability to develop socially appropriate interpersonal communication skills and has developed no real friendships. He is dependent on others for assistance with his basic needs, such as dressing and feeding. Which of the following diagnoses most accurately represents this presentation?
A. Autism spectrum disorder
Autism spectrum disorder primarily involves deficits in social communication and restricted/repetitive behaviors. While some overlap exists, the primary issue here is broad cognitive impairment affecting adaptive functioning, which is more consistent with intellectual disability.
B. Global developmental delay
Global developmental delay applies to children under age 5 with delays in multiple developmental domains. At age 10, this diagnosis is no longer appropriate; intellectual disability is diagnosed instead.
C. Intellectual disability
This choice is correct because intellectual disability is defined by deficits in intellectual functioning (reasoning, problem-solving, learning) and adaptive functioning (communication, social participation, daily living skills). The description matches both criteria.
D. Childhood-onset neurocognitive disorder
Childhood-onset neurocognitive disorder is generally reserved for disorders like early-onset dementia or acquired cognitive impairments, not congenital or developmental intellectual deficits.
