Blood pressure is measured by:

Question

Blood pressure is measured by:

1. A. Barometer
2. B. Lactometer
3. C. Sphygmomanometer (Correct answer)
4. D. Glucometer

Correct Answer

Option C — Sphygmomanometer

Detailed Solution & Explanation

The correct answer is Sphygmomanometer.

Key Points

• Blood pressure is measured with a sphygmomanometer, using an inflatable cuff and a pressure gauge.
• The distractors measure other quantities: a barometer measures atmospheric pressure, a lactometer the purity of milk, and a glucometer blood glucose.

Additional Information

• A reading gives two numbers — systolic (heart contracting) over diastolic (heart relaxing); normal is about 120/80 mm Hg.
• Persistently high readings indicate hypertension, low ones hypotension.
• Other instrument pairings worth revising: seismograph (earthquakes), hygrometer (humidity), anemometer (wind speed), ammeter (current), odometer (distance).
