Answer:
The nurse should say that some parts of the patient's brain were affected by the stroke. For this reason the patient is experiencing these sudden mood swings.
Explanation:
A stroke occurs when the blood supply to the brain is interrupted or dramatically reduced, depriving the banknotes of oxygen and nutrients. Or, when a blood vessel ruptures, causing a brain hemorrhage. Causes of these occurrences include cerebral arterial malformation (aneurysm), arterial hypertension, heart disease, thromboembolism (pulmonary artery block).
Stroke directly affects the brain. Injured brain areas can result in the patient's strange behaviors, such as smiling at a time and starting to cry shortly afterwards, as shown in the question above.
The areas of the brain affected by stroke may gradually reconstruct if given the right stimuli. Therefore, rehabilitation programs are very important as they help the patient to resume daily activities and functions that have been compromised.
