Encouraging mouth exhalation during defecation for a client with a cerebral aneurysm is primarily aimed at decreasing intra-abdominal pressure. This is crucial because increased intra-abdominal pressure can lead to increases in intracranial pressure, which may further endanger a patient with a cerebral aneurysm. By promoting the practice of exhaling through the mouth rather than straining or holding breath, the client is less likely to generate excessive pressure which could destabilize their condition, particularly if an aneurysm is present.

Managing intra-abdominal pressure is important for maintaining stable intracranial pressure and reducing the risk of complications associated with cerebral aneurysms, such as rupture or additional neurological damage. Therefore, this intervention supports the overall safety and well-being of the patient during the potentially straining act of defecation.
