Explanation

The value 120/80 mm Hg is the widely accepted benchmark for normal blood pressure in healthy adults.
According to ACC/AHA guidelines, a normal systolic pressure is less than 120 mm Hg and a normal diastolic pressure is less than 80 mm Hg.
In a multiple-choice setting, 120/80 mm Hg represents the ideal or standard normal value that other readings are compared against.

Option A: A blood pressure of 130/90 mm Hg is not normal; it is classified as Stage 1 Hypertension according to current guidelines.
Option B: While a reading of 110/65 mm Hg is considered healthy and falls within the normal range, 120/80 mm Hg is the specific standard reference value for 'normal' blood pressure that is typically tested.
Option D: A blood pressure of 140/90 mm Hg is significantly elevated and is classified as Stage 2 Hypertension.

Clinical Relevance

Nursing practice connection: Knowing Normal blood pressure values and hypertension classification in adults helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Hypertension is often called the 'silent killer' because it usually has no symptoms but is a major risk factor for heart disease, stroke, and kidney failure. Regular monitoring is crucial.
Nurses play a key role in educating patients about lifestyle modifications to manage blood pressure, including a low-sodium diet, regular exercise, weight management, and limiting alcohol.
Accurate blood pressure measurement is a fundamental nursing skill. Using the wrong cuff size is a common error; a cuff that is too small will give a falsely high reading, while a cuff that is too large will give a falsely low reading.

How to Approach the Question

First, identify the core of the question, which is asking for the 'normal' range of a key physiological parameter (blood pressure) in an 'adult'.
This is a factual recall question. Access your knowledge of standard vital signs.
Recall the benchmark value for normal adult blood pressure. The most universally taught value is 120/80 mm Hg.
Evaluate the given options against this standard. 120/80 mm Hg is present as an option.
Eliminate the other options by categorizing them. 130/90 and 140/90 are high (hypertensive). 110/65 is also normal, but 120/80 is the specific standard reference point.
Select the option that represents the established clinical standard for 'normal'.
