In a client with untreated stage 1 hypertension, what is the expected minimum systolic pressure?

Stage 1 hypertension is defined by specific systolic and diastolic blood pressure ranges. The criteria established by organizations such as the American Heart Association classify stage 1 hypertension with a systolic blood pressure ranging from 130 to 139 mm Hg or a diastolic blood pressure between 80 and 89 mm Hg.

In the context of the provided choices, the expected minimum systolic pressure for a diagnosis of stage 1 hypertension falls into the range where the systolic pressure starts at 130 mm Hg. The correct answer aligns with the definition of stage 1 hypertension, indicating that a systolic pressure of 140 mm Hg establishes the lower limit for this stage. Hence, the correct option reflects this understanding of stage 1 hypertension's minimum threshold.

Values that fall below 140 mm Hg, such as the lower choices, do not meet the criteria for stage 1 hypertension, thereby confirming the selected answer as the appropriate classification for untreated stage 1 hypertension.
