A nurse is assessing a patient with activity intolerance for possible orthostatic hypotension. Which finding will help confirm orthostatic hypotension?
a. Blood pressure sitting 120/64; blood pressure 140/70 standing
b. Blood pressure sitting 126/64; blood pressure 120/58 standing
c. Blood pressure sitting 130/60; blood pressure 110/60 standing
d. Blood pressure sitting 140/60; blood pressure 130/54 standing
ANS: C
Orthostatic hypotension results in a drop of 20 mm Hg systolic or more in blood pressure when rising from sitting position (110/60). 120 to 140 means the blood pressure increased rather than dropped. 126 to 120 is only a six points' difference. 140 to 130 is only a 10 points' difference.
