Certified Nursing Assistant (CNA) Practice Exam

Where does a nursing assistant place their fingers to count the pulse rate at the most common site?

1. Carotid artery

2. Femoral artery

3. Radial artery

4. Temporal artery

The correct answer is: Radial artery

The most common site for a nursing assistant to count the pulse rate is on the radial artery, which is located on the wrist, approximately at the base of the thumb. This site is preferred because it is easily accessible and allows for a comfortable position for the patient, making it an efficient and practical location for monitoring the pulse. Using the radial artery also provides a clear and often strong pulse that is easy to palpate, which is essential for accurate measurements. Additionally, counting the pulse at this site allows the nursing assistant to observe the strength and rhythm of the heartbeat as well, providing valuable information about the patient’s cardiovascular health. While other arteries like the carotid, femoral, and temporal arteries can be used to measure pulse, they are less commonly employed in routine practice for various reasons, including accessibility and the need for more invasive or cautious approaches.
