Hypotension is rarely clinically significant unless the client is symptomatic, i.e. they are dizzy, weak or experiencing syncopal (passing out) or near syncopal episodes. If a client's BP is 85/50 (as mine often is), they report that is a normal pressure for them them, and they deny symptoms, that BP is usually fine. Though there are some complications with extremely low BP they are not generally a concern in a healthy, active adult.
