Answer :
When taking a pulse, it is generally recommended not to use your thumb. The reason for this is that the thumb has its own pulse, which can interfere with the accuracy of the pulse measurement.
The pulse is typically measured by applying light pressure with the fingertips over an artery, such as the radial artery on the wrist.
By feeling the pulsations, you can determine the rate, rhythm, and strength of the heartbeat.
Using the thumb to take a pulse can introduce inaccuracies because the thumb has its own pulse, known as the "thumb pulse."
When you press with your thumb, you may inadvertently feel your own pulse rather than the pulse of the person whose pulse you are trying to measure.
This can lead to an incorrect reading and misinterpretation of the person's actual pulse rate and rhythm.
To obtain an accurate pulse measurement, it is best to use the pads of your first two or three fingers (usually the index and middle fingers) to feel the pulse.
By avoiding the thumb, you can reduce the chances of feeling your own pulse and obtain a more reliable assessment of the person's pulse characteristics.
It is recommended to exclude the thumb when taking a pulse to ensure the accuracy of the measurement and to avoid any potential confusion or misinterpretation.
