Explanation

120 mm Hg is the standard upper limit reference value for normal systolic blood pressure in adults.
Systolic pressure represents the maximum pressure exerted on the arterial walls during the heart's contraction (systole).
A 'textbook' normal blood pressure reading is commonly cited as 120/80 mm Hg, where 120 is the systolic value.

Option A: This value represents the standard for normal diastolic blood pressure, which is the pressure in the arteries when the heart is at rest between beats.
Option B: While a systolic pressure of 95 mm Hg is considered healthy and falls within the normal range, it is not the standard upper reference value used to define the category.
Option C: A systolic pressure of 110 mm Hg is a healthy reading. However, in the context of standardized testing, 120 mm Hg is the specific benchmark for the upper limit of normal systolic pressure.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Normal Blood Pressure Values as background academic context rather than a clinical decision trigger.
Accurate blood pressure measurement is a fundamental nursing skill essential for assessing a patient's cardiovascular health and identifying risks for conditions like hypertension or hypotension.
Consistently elevated readings may indicate hypertension, a major risk factor for stroke, heart disease, and kidney failure. This requires prompt patient education on lifestyle modifications and ensuring follow-up with a physician.
What if? - If a patient's reading is consistently 135/85 mm Hg, they would be classified as having Stage 1 Hypertension. The nurse's priority would shift to providing education on diet, exercise, and stress management, and documenting the findings for the healthcare team to consider antihypertensive therapy.

How to Approach the Question

This is a factual recall question that tests your knowledge of fundamental vital signs.
First, identify the key term in the question: 'systolic BP'.
Recall the standard 'textbook' blood pressure reading, which is 120/80 mm Hg.
Differentiate between the top number (systolic pressure) and the bottom number (diastolic pressure).
Evaluate the options provided and select the one that corresponds to the standard systolic value.
Eliminate options that represent diastolic pressure (80) or are simply within the normal range but not the standard reference point (95, 110).
