Final answer:
Doris' blood pressure reading of 163/95 mm Hg categorizes her as having Stage 2 hypertension, exceeding the threshold for hypertension and indicating a need for medical management.
Step-by-step explanation:
Doris, a 73-year-old with a blood pressure reading of 163/95 mm Hg, falls into the Stage 2 hypertension category. According to the American College of Cardiology and the American Heart Association guidelines, hypertension is defined as a systolic blood pressure of 130 mm Hg or higher or a diastolic blood pressure of 80 mm Hg or higher. Therefore, Doris' reading significantly exceeds these thresholds and indicates a chronic and persistent elevation of blood pressure that requires medical attention and possible lifestyle modifications or medications to manage her condition and minimize the risk of complications such as heart disease, stroke, or kidney problems.
