What alteration in function should be expected in a client with a right hemisphere stroke?

When considering the alterations in function following a right hemisphere stroke, one of the primary consequences is the impairment of the ability to recognize familiar faces and places, known as prosopagnosia, which is closely tied to the right hemisphere's role in visual perception and emotional processing. In a client experiencing a right hemisphere stroke, the right side of the brain, which is responsible for processing visual and spatial information and understanding nonverbal cues, becomes damaged. This results in difficulties in recognizing family members and familiar faces due to disrupted connections in areas that process visual stimuli.

The right hemisphere is also associated with the ability to interpret social and emotional cues, which can further exacerbate challenges in recognizing familiar individuals beyond mere visual recognition. Therefore, the inability to recognize family members is a key alteration in function that can be expected in such cases, making this option the most appropriate choice.
