A nurse is reinforcing teaching with a newly licensed nurse about orthostatic hypotension. Which of the following information should the nurse include?

A. When a client experiences a sudden drop in blood pressure upon standing, cerebral perfusion can decrease, leading to dizziness, lightheadedness, or syncope, which significantly increases fall risk. B. Orthostatic hypotension is not directly associated with pulmonary emboli. PE risk factors include immobility, surgery, or hypercoagulable states, not transient drops in blood pressure. C. The diagnostic criterion is a decrease of ≥10 mm Hg in diastolic blood pressure, so 5 mm Hg would not be sufficient to indicate orthostatic hypotension. D. The formal criterion is a decrease of ≥20 mm Hg in systolic blood pressure upon standing, not 10 mm Hg.
