A nurse is assessing a patient with activity intolerance for possible orthostatic hypotension. Which finding will help confirm orthostatic hypotension?

Choice A reason: A drop in systolic blood pressure from 140 to 130 mmHg and a drop in diastolic blood pressure from 60 to 50 mmHg indicates a decrease in blood pressure upon standing. However, the diastolic drop is not significant enough to confirm orthostatic hypotension according to standard criteria. Choice B reason: A drop in systolic blood pressure from 130 to 110 mmHg upon standing, with diastolic pressure remaining the same, indicates a significant decrease in systolic blood pressure. This meets the criteria for orthostatic hypotension, which is defined as a decrease in systolic blood pressure of 20 mmHg or more, or a decrease in diastolic blood pressure of 10 mmHg or more within three minutes of standing. Choice C reason: A drop in systolic blood pressure from 126 to 120 mmHg and a drop in diastolic blood pressure from 64 to 58 mmHg does not meet the criteria for orthostatic hypotension. The changes are not significant enough to confirm the condition. Choice D reason: An increase in blood pressure from 130/64 to 140/70 mmHg upon standing is not consistent with orthostatic hypotension. Instead, this finding suggests an increase in blood pressure, which does not support the diagnosis of orthostatic hypotension.
