Final answer:
An individual with stage 2 hypertension has a systolic blood pressure of 140 mm Hg or higher and a diastolic blood pressure of 90 mm Hg or higher. This condition requires medical attention due to the associated health risks.
Step-by-step explanation:
The systolic and diastolic rates for an individual considered to be in stage 2 hypertension according to the guidelines by the American College of Cardiology and the American Heart Association, are classified as a systolic blood pressure of 140 mm Hg or higher and a diastolic blood pressure of 90 mm Hg or higher.
Hypertension, often referred to as high blood pressure, is a condition that can lead to significant health issues such as heart attack, stroke, and kidney failure if not properly managed. Systolic pressure measures the force of blood against artery walls during heartbeats, while diastolic pressure measures this force during the heart's rest in between beats. Stage 2 hypertension is a serious condition that typically requires medical treatment which may include lifestyle changes and medication.
