Instrument for Blood Pressure Measurement
The question asks to identify the specific instrument used for measuring blood pressure. Blood pressure is the pressure of circulating blood against the walls of blood vessels, most notably the systemic arterial pressure. Measuring it is crucial for assessing cardiovascular health.
Understanding Blood Pressure Measurement Instruments
Several medical devices are used for different diagnostic purposes. Let's look at the options provided:
- Spirometer: This device is used to measure lung function, specifically the volume of air inhaled or exhaled over time. It helps diagnose conditions like asthma or COPD.
- Sphygmomanometer: This is the primary instrument designed specifically to measure blood pressure. It typically consists of an inflatable cuff, a measuring unit (aneroid gauge or mercury column), and a mechanism for inflation (bulb and valve). It is often used in conjunction with a stethoscope.
- Glucometer: This is a portable electronic device used to measure the approximate concentration of glucose in the blood. It is essential for people managing diabetes.
- Electroencephalograph (EEG): This instrument is used to record the electrical activity of the brain. It helps in diagnosing conditions such as epilepsy, sleep disorders, and brain tumors.
Identifying the Correct Instrument
Based on the functions described above, the instrument specifically designed and used for measuring blood pressure is the Sphygmomanometer.
Summary of Instruments
| Instrument Name | Function |
|---|---|
| Spirometer | Measures lung capacity and air volume |
| Sphygmomanometer | Measures blood pressure |
| Glucometer | Measures blood glucose levels |
| Electroencephalograph | Records brain's electrical activity |
Therefore, the correct instrument for measuring blood pressure among the choices is the Sphygmomanometer.

- An empty plastic mug floats in a bucket of water. When a solid iron ball is kept in the mug it doesn't sink. When the ball is put in the water it sinks. Compared to when the ball is in water, the water level in the bucket when the ball is in the mug is
Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): Creative thinking always requires divergent thinking.
Reason (R): Divergent thinking helps in generating multiple solutions to a single problem.
