Hypotension refers to which of the following?

• A. Blood pressure above 140/90
• B. Blood pressure below 100/65
• C. Normal blood pressure range
• D. Fluctuating blood pressure

Answer: (B)

Hypotension is defined as abnormally low blood pressure, which is typically recognized when the systolic pressure is below 90 mmHg or the diastolic pressure is below 60 mmHg. The threshold often cited for hypotension varies somewhat among different guidelines, but a blood pressure reading of below 100/65 mmHg is commonly considered indicative of hypotension. This reading can lead to symptoms such as dizziness, fainting, or shock.

In contrast, the other options describe different scenarios: blood pressure above 140/90 signifies hypertension, a normal blood pressure range refers to levels generally between 90/60 and 120/80 mmHg, and fluctuating blood pressure pertains to varying readings over time, which does not specifically indicate low blood pressure.
