What vital sign can be assessed by palpating the radial pulse?

The ability to assess heart rate through palpation of the radial pulse is fundamental in clinical practice. The radial pulse is found at the wrist along the radial artery, and it provides a readily accessible means of evaluating the number of heartbeats per minute. This rate can indicate various health conditions, including cardiovascular status and overall body function.

When assessing the radial pulse, a practitioner counts the beats for a set time, commonly for 30 seconds and then multiplying by two, or for a full minute for accuracy. This pulse reflects the heart's activity as it pumps blood through the arteries, making it a direct measurement of heart rate.

In contrast, respiratory rate requires observation of breath movements and is not measurable at the radial pulse. Blood pressure needs a sphygmomanometer or similar device for accurate measurement and does not involve palpation of the pulse. Body temperature is measured using a thermometer and does not relate to pulse evaluation. Therefore, the radial pulse specifically and effectively provides information about the heart rate.
