When monitoring for orthostatic hypotension, within what timeframe should BP be measured after standing?

• A. A 5 minutes after standing
• B. B Within 1 minute of standing
• C. C 10 minutes after standing
• D. D Before standing

Answer: (B)

When you test for orthostatic changes, the important timing is right after the patient stands. The body’s veins pool blood quickly when standing, and the initial drop in blood pressure happens right away as venous return falls and the autonomic system reacts. Measuring within one minute of standing captures that immediate change before the compensatory mechanisms raise the pressure back up. If you wait longer, the blood pressure may have already rebounded, making the hypotension harder to detect. Baseline measurement should be taken supine before standing, and waiting several minutes after standing risks missing the drop that indicates the issue.
