Question

Blood pressure is measured by
A) Sphygmomanometer
B) Phonocardiogram
C) Electrocardiogram
D) Stethoscope

Answer 1

Hint: A normal and healthy human being should have a top blood pressure in the range of 90 to 120 mmHg and a low blood pressure in the range of 60 and 80 mmHg.

Complete Answer:
Option A: Sphygmomanometer is an instrument for determining the blood pressure containing an inflatable rubber cuff. The instrument is applied to the arm and is connected to a mercury level in the graduated scale. Thus, this is the correct option.
Blood pressure is often expressed as a fraction containing a top number and a low number. For exp – 120/80 mmHg.
- Systolic Pressure – The top number of this fraction represents the pressure in your arterial walls when your heart muscle lies in the state of contraction.
- Diastolic Pressure – The bottom number of this fraction refers to the pressure of the blood when your heart muscles lie between beats.

Option B: Phonocardiogram represents the sound recorded by the movement of our heart muscles. Thus, this is the incorrect option.

Option C: An electrocardiogram is a simple and painless test for measuring the electrical activity of your heart muscles. Thus, this is the incorrect option.

Option D: Stethoscope is an acoustic medical device for listening to the internal sounds existing within the human body or auscultation. Thus, this is the incorrect option.

Thus, the correct option is a)Sphygmomanometer.

Note: Sphygmomanometer is used in conjunction with a stethoscope for listening to the sound made by arterial blood flow.
