NCLEX Hypertension Practice Test 2025 - Free Hypertension Practice Questions and Study Guide

Stage 1 hypertension is defined by specific blood pressure ranges according to the American College of Cardiology and the American Heart Association. For adults, stage 1 hypertension is classified as having a systolic blood pressure ranging from 130 mm Hg to 139 mm Hg or a diastolic blood pressure ranging from 80 mm Hg to 89 mm Hg. Therefore, the maximum systolic blood pressure recognized for stage 1 hypertension should not exceed 139 mm Hg.

Recognizing that options A (159 mm Hg) and B (160 mm Hg) exceed this threshold confirms they cannot be classified as stage 1 hypertension. On the other hand, option D (140 mm Hg) is actually classified as stage 2 hypertension, as it goes beyond the maximum systolic limit for stage 1.

Understanding these classifications is crucial for proper diagnosis and management of hypertension, ensuring timely intervention to reduce risks associated with elevated blood pressure levels.
