A patient arrives at the emergency department with a blood pressure reading of 148/94 mm Hg. According to the American Heart Association (AHA) guidelines, how should this blood pressure level be categorized?

1. A

   Normal

2. B

   Elevated

3. C

   Hypertension stage 1

4. D

   Hypertension stage 2

Explanation

Listen in Hindi

• According to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guidelines, blood pressure is categorized based on systolic and diastolic values.
• The patient's systolic pressure is 148 mm Hg, which meets the criterion for Stage 2 Hypertension (140 mm Hg or higher).
• The patient's diastolic pressure is 94 mm Hg, which also meets the criterion for Stage 2 Hypertension (90 mm Hg or higher).
• When systolic and diastolic pressures fall into different categories, the higher category is used. In this case, both values clearly indicate Stage 2.

Why Other Options Were Wrong

• Option A: A normal blood pressure reading is defined as a systolic pressure less than 120 mm Hg AND a diastolic pressure less than 80 mm Hg. The patient's reading of 148/94 mm Hg is significantly higher.
• Option B: Elevated blood pressure is defined as a systolic pressure of 120–129 mm Hg AND a diastolic pressure of less than 80 mm Hg. The patient's reading exceeds both of these ranges.
• Option C: Hypertension Stage 1 is defined as a systolic pressure of 130–139 mm Hg OR a diastolic pressure of 80–89 mm Hg. The patient's reading of 148/94 mm Hg is above this range.

Clinical Relevance

• Nursing practice connection: Prioritize focused assessment, early escalation, and real-time monitoring when managing Blood pressure classification based on AHA guidelines in acute care settings.
• Accurate classification of blood pressure is the first step in risk stratification and determining the urgency and type of management required to prevent long-term complications like heart disease, stroke, and kidney failure.
• Nurses are at the forefront of hypertension screening, patient education, and monitoring. Correctly identifying the stage of hypertension allows the nurse to provide appropriate education on lifestyle modifications and the importance of medication adherence.
• What if? If the patient's reading was 138/88 mm Hg, it would be classified as Hypertension Stage 1. This would prompt the nurse to educate the patient on intensive lifestyle changes (diet, exercise, sodium restriction) and prepare them for a discussion with the provider about potentially starting a single antihypertensive medication, depending on their overall cardiovascular risk.

How to Approach the Question

• First, identify the key clinical data provided in the question: the patient's blood pressure reading is 148/94 mm Hg.
• Next, recall the standard blood pressure classification guidelines, specifically the categories defined by the AHA/ACC.
• Analyze the systolic value (148 mm Hg) by comparing it to the guideline thresholds.
• Analyze the diastolic value (94 mm Hg) by comparing it to the guideline thresholds.
• Apply the rule that if systolic and diastolic values fall into different categories, the higher category determines the final classification. In this instance, both 148 (systolic) and 94 (diastolic) fall into the Stage 2 category.
• Select the option that correctly matches this classification.
