What method would a CNA likely use to measure a patient's pulse?

The radial method is the most commonly used technique for measuring a patient's pulse because it is easily accessible and allows for a quick assessment of heart rate. The radial pulse is found on the wrist, near the thumb, making it convenient for a CNA to feel and count the beats. It provides a reliable measure of heart rate and can be done unobtrusively while attending to a patient’s care.

In contrast, while the brachial pulse can also be used, it is typically measured in the context of blood pressure assessments. The femoral and popliteal pulses are more invasive to access and are generally utilized in specific scenarios, such as assessing circulation in the lower extremities. Thus, using the radial pulse strikes an optimal balance between ease of access and reliability for routine monitoring of a patient's heart function.
