In the case of a patient with a suspected abdominal aortic aneurysm (AAA), deep palpation of the abdomen is CONTRAINDICATED or could cause harm.
Deep palpation could potentially rupture the aneurysm, leading to severe complications such as massive internal bleeding. The other assessments listed, such as monitoring level of consciousness and blood pressure, and auscultation of the abdomen for bowel motility and for bruit, are non-invasive and do not carry the same risk.
