Question

After a cerbrovascular accident (CVA, also known as "brain attack"), a client is unable to differentiate between heat or cold and sharp or dull sensory stimulation. The nurse would conclude that CVA affected which lobe of the brain?

Answer 1

A client unable to differentiate between heat, cold, and sharp or dull sensations after a stroke likely has damage to the parietal lobe, which is responsible for processing sensory input.

Step-by-step explanation:

After experiencing a cerebrovascular accident (CVA), commonly known as a stroke, if a client is unable to differentiate between heat or cold and sharp or dull sensory stimulation, the most likely affected lobe of the brain would be the parietal lobe. The parietal lobe is responsible for processing sensory input, including the temperature and touch sensations mentioned. A stroke causing a loss of neurological function due to an interruption of blood flow can result in deficits in the regions of the central nervous system that have been affected. The sensory deficits described are directly related to the somatosensory cortex's functions, which are located in the parietal lobe. Therefore, damage to this region due to a stroke could explain the inability to distinguish between different sensory stimuli.
