A 78-year-old starts a new antihypertensive. During a supervised postural assessment, the nurse compares each standing measurement with the supine baseline. Click the earliest displayed standing measurement that meets the blood-pressure drop criterion for orthostatic hypotension.

D. D shows a 22-mm Hg systolic and 12-mm Hg diastolic fall from the supine baseline.

The supine value is 154/88. Subtract each standing value from this baseline rather than comparing only adjacent points. At three minutes, 154 minus 132 is 22 and 88 minus 76 is 12, meeting the blood-pressure criteria. There are no symptoms requiring an earlier stop in this fictional record.

The observations are fictional teaching data. Apply the stated context; the selected feature does not by itself replace a complete bedside assessment.

Compare standing pressure with supine baseline and consider symptoms at every check.

Compare standing pressure with supine baseline and consider symptoms at every check.

A is the reference, not a standing result. B falls 10/4 mm Hg. C falls 16/6 mm Hg. Neither B nor C meets the 20-systolic or 10-diastolic drop threshold.

• Postural change relative to supine baseline — Compare standing pressure with supine baseline and consider symptoms at every check.
• Comparison with context — C is lower than baseline but the numerical fall has not yet reached the criterion.
