What is the normal systolic or top blood pressure number?

• A. 60 to 100
• B. 90 to 100
• C. 90 to 140
• D. 120 to 180

Answer: (C)

The top number you see in a blood pressure reading is systolic pressure—the pressure in the arteries when the heart contracts. In many CNA-focused guidelines, a normal systolic value is considered to fall roughly from 90 up to about 140 mm Hg. The lower end around 90 indicates enough force to push blood to vital organs, while reaching up to around 140 is still treated as acceptable within that context. Values well above 140 tend to signal hypertension and need monitoring, while readings much lower than 90 could mean insufficient perfusion. So, in this context, the normal range is about 90 to 140 mm Hg.
