Final answer:
The standard procedure for taking a client's pulse is to measure it for one minute to accurately determine their heart rate. Counting the number of heartbeats for a shorter period, like 10 seconds, can give an estimate, but may not be as precise for individuals with irregular heart rhythms.
Step-by-step explanation:
When taking a client's pulse, the standard practice is to measure it for one minute (Option B). This duration is recommended to ensure accuracy in reading the number of heartbeats, which reflects the heart's function and the individual's cardiovascular health. Feeling your pulse gives you an indication of your heart rate, or the number of times your heart beats in a minute.
If you measure your pulse for 10 seconds and multiply the number of beats by 6, it should theoretically give you the heart rate per minute, assuming the heart rate is steady. However, counting for a full minute is more reliable, particularly for those with irregular heart rhythms. During strenuous exercise, if your heart rate is 150 beats per minute, the time per beat, in units of seconds, is 60 seconds divided by 150, which equals 0.4 seconds per beat.
