The PMHNP is working on an inpatient geropsychiatric unit. He is conducting the Montreal Cognitive Assessment (MoCA) on an 89-year-old woman with suspected dementia. He asks her to draw a clock to test her praxis abilities. Which area of the brain is responsible for this function?

Choice A reason: The left parietal lobe is primarily involved in language, calculation, and sequential tasks, not spatial construction and praxis, which are essential for clock drawing. Choice B reason: This choice is correct because the right (nondominant) parietal lobe is responsible for visuospatial processing and praxis, including the ability to perceive spatial relationships and reproduce them accurately, as required in clock-drawing tasks. Choice C reason: The temporal lobe is involved in memory, auditory processing, and language comprehension, not visuospatial praxis. Choice D reason: The occipital lobe is responsible for primary visual processing, but the integration of spatial planning for drawing tasks involves parietal lobe function.
