Final answer:
A slightly to moderately abnormal Ankle-Brachial Index (ABI) value is 0.7 - 0.9, indicating some arterial blockage and potential for peripheral arterial disease.
The Correct Option is; a) 0.7 - 0.9
Step-by-step explanation:
The Ankle-Brachial Index (ABI) is a simple, non-invasive test used to screen for peripheral arterial disease (PAD). The ABI is calculated by dividing the systolic blood pressure at the ankle by the systolic blood pressure in the arm. A slightly to moderately abnormal ABI range is 0.7 - 0.9. This range indicates some blockage and the potential for PAD, suggesting a need for lifestyle changes and possibly medical intervention to prevent further cardiovascular problems.
The subject of this question is Health.
ABI stands for Ankle-Brachial Index, which is a screening tool used to assess the blood flow in the lower limbs. It is a comparison of the blood pressure at the ankle with the blood pressure at the arm. A slightly to moderately abnormal ABI falls within the range of 0.7 - 0.9, option a).
