Where should you place your fingers to take a radial pulse?

• A. On the posterior side of the knee, in the popliteal fossa
• B. On the anterior side of the neck, beside the trachea
• C. On the lateral side of the wrist, just below the thumb
• D. On the medial side of the ankle, behind the medial malleolus

Answer: (C)

Verified step by step guidance

1. Understand the concept of a radial pulse: The radial pulse is the rhythmic expansion of the radial artery, which is located on the lateral side of the wrist. It is commonly used to measure heart rate because it is easily accessible.
2. Identify the anatomical location of the radial artery: The radial artery runs along the lateral side of the forearm and wrist, near the base of the thumb. This is the area where you would place your fingers to feel the pulse.
3. Learn the proper technique for taking a radial pulse: Use the pads of your index and middle fingers to gently press on the lateral side of the wrist, just below the thumb. Avoid using your thumb, as it has its own pulse that can interfere with accurate measurement.
4. Compare the radial pulse location to other pulse points: For example, the popliteal pulse is located in the posterior side of the knee, the carotid pulse is beside the trachea in the neck, and the posterior tibial pulse is behind the medial malleolus of the ankle. These are different pulse points used for specific purposes.
5. Practice locating the radial pulse on yourself or a partner: This hands-on practice will help you become familiar with the anatomical landmarks and improve your ability to locate the radial pulse quickly and accurately.
