Final answer:
The blood pressure indicative of stage 1 hypertension is 130/80 mm Hg.
Step-by-step explanation:
The blood pressure reflective of stage 1 hypertension (HTN) is 130/80 mm Hg. According to the new guidelines from the American College of Cardiology and the American Heart Association, normal blood pressure is defined as less than 120/80 mm Hg, whereas stage 1 hypertension is defined as a blood pressure of 130/80 mm Hg or higher. Therefore, option 2) 130/80 mm Hg is the correct answer. It's also important to understand the concept of pulse pressure, which is the difference between the systolic and diastolic pressures, indicating the force that the heart generates each time it contracts.
