26
Q

Temporal lobe

A
  • controls auditory functions
  • hold Wernicke’s area
  • ability to organize and understand speech
  • controls limbic and hippocampus
    • emotions (limbic)
    • memory (hippocampus)
27
Q

Choice A is correct. Visual disturbances are expected for a client with a stroke impacting the occipital lobe of the brain. The occipital lobe is the primary optical center of the brain. Homonymous hemianopia is a complete left or right visual field defect. The client may need to be taught to scan the room, and the nurse should place objects in the unaffected visual field.

Choice B is incorrect. Proprioception is for the client to have an awareness of their body position. Testing a client’s proprioception is done via the Romberg test. If the client should have impairments with proprioception, this highly suggests an insult to the parietal lobe, which primarily processes sensory input, proprioception, and taste.

Choice C is incorrect. Expressive aphasia and impulsivity can be explained as an insult to the frontal lobe, which is the brain’s executive center. Broca’s area can be found in the frontal lobe and, if damaged, may cause the client to have expressive aphasia.

Choice D is incorrect. Impulsivity is also a feature of a stroke that primarily affects the frontal lobe, as this lobe controls cognition, judgment, affective response to situations, and reasonable deduction.

A
  • Visual disturbances are expected for a client with a stroke impacting the occipital lobe of the brain.
  • Expressive aphasia and impulsivity can be explained as an insult to the frontal lobe, which is the brain’s executive center. Broca’s area
    • Impulsivity is also a feature of a stroke that primarily affects the frontal lobe, as this lobe controls cognition, judgment, affective response to situations, and reasonable deduction.
