Final answer:
The absence of lower extremity edema is the most indicative finding of effective hypertension management.
Step-by-step explanation:
A finding that is most indicative of effective hypertension management is there is no indication of lower extremity edema. Lower extremity edema, or swelling in the legs and feet, is a common symptom of uncontrolled hypertension. It occurs when fluid builds up in the tissues due to increased pressure in the blood vessels.
Therefore, the absence of lower extremity edema suggests that the client's blood pressure is well-controlled. Other options, such as the client's weight stability or blood pressure reading, may be helpful but do not provide a direct indication of effective hypertension management.
