Final answer:
The nurse should expect difficulty comprehending instructions in a patient with left hemisphere stroke as this part of the brain is responsible for language and speech functions.
Step-by-step explanation:
A patient admitted with a stroke exhibiting right-sided facial drooping and right-sided arm and leg paralysis likely has damage to the left hemisphere of the brain, which is typically associated with language and speech functions. Given these symptoms, the nurse should expect difficulty comprehending instructions (option d), which aligns with the impact of a left-hemisphere injury on communication and understanding abilities. When the right side of the brain is damaged, it can lead to a loss in the ability to understand aspects of speech like jokes, irony, or metaphors, but the characteristic symptoms presented by the patient point towards left-hemisphere damage and subsequent language comprehension issues, rather than issues such as impulsive behavior, right-sided neglect, or hyperactive left-sided tendon reflexes.
