Final answer:
The most likely behavior that will be observed in the client with a hemorrhagic stroke affecting the upper trunk of the middle cerebral artery is the inability to dress the left side of the body. This is known as spatial neglect.
Step-by-step explanation:
Based on the pattern of impairment and cortical involvement, the most likely behavior that will be observed in the client with a hemorrhagic stroke affecting the upper trunk of the middle cerebral artery is the inability to dress the left side of the body.
This is known as spatial neglect, which is a common consequence of strokes that affect the right side of the brain. Spatial neglect causes the individual to have difficulty attending to and recognizing stimuli on the left side of their body or in their visual field.
Examples of spatial neglect include not dressing the left side of the body, not noticing items on the left side of a table, or not eating food from the left side of a plate.
