Final answer:
A right-sided brain tumor with increased ICP can result in contralateral hemiparesis, altered level of consciousness, and potentially contralateral pupil dilation.
Step-by-step explanation:
A patient with a right-sided brain tumor causing significant increased intracranial pressure (ICP) can exhibit a variety of neurological deficits. Since the right side of the brain controls the left side of the body, one can expect to see contralateral hemiparesis, meaning weakness on the left side of the body. Additionally, due to pressure effects, altered level of consciousness can occur, which may present as confusion, drowsiness, or difficulty waking. Pupil dilation can also be affected, typically resulting in ipsilateral dilation (the same side as the tumor); however, if the pressure affects the third cranial nerve on the opposite side, contralateral pupil dilation may also be seen.
