What is a possible mistake about a blood pressure of 120/80 in a 87 year old

How well do geriatric patients do with non-operative management of
abdominal injuries compared to younger people? - CORRECT-ANSWERSNot
as well - the risks of non-operative management are often worse than the
risks of surgery.
