Final answer:
Option D (130/92) is within the expected reference range for blood pressure as the systolic pressure is below 120 and the diastolic pressure is below 80.
Step-by-step explanation:
The expected reference range for blood pressure is generally considered to be below 120/80 mm Hg. Let's analyze each option to determine whether it falls within the expected range:
A. 142/85: The systolic pressure (142) is higher than the normal range, indicating high blood pressure. The diastolic pressure (85) is within the normal range.
B. 135/88: Both the systolic (135) and diastolic (88) pressures are higher than the normal range, indicating high blood pressure.
C. 150/72: The systolic pressure (150) is higher than the normal range, indicating high blood pressure. The diastolic pressure (72) is within the normal range.
D. 130/92: The systolic pressure (130) is within the normal range. The diastolic pressure (92) is higher than the normal range, indicating high blood pressure.
Based on the analysis, option D (130/92) is within the expected reference range for blood pressure as the systolic pressure is below 120 and the diastolic pressure is below 80.
