Verified step by step guidance

Step 1: Understand the anatomy of the forearm and wrist. The forearm is supplied by two main arteries: the radial artery and the ulnar artery. These arteries branch from the brachial artery, which itself is a continuation of the axillary artery.

Step 2: Recall the location of the radial artery. The radial artery runs along the lateral (thumb-side) aspect of the forearm and is superficial near the wrist, making it easily accessible for pulse measurement.

Step 3: Compare the radial artery to the other options. The brachial artery is located in the upper arm, not the forearm. The ulnar artery runs along the medial (pinky-side) aspect of the forearm but is less commonly used for pulse measurement. The axillary artery is located in the armpit region and does not supply the forearm directly.

Step 4: Recognize that the radial artery is the most commonly used artery for measuring pulse at the wrist due to its superficial location and ease of palpation.

Step 5: Conclude that the correct answer is the radial artery, as it is the main blood supply to the forearm and is commonly used for pulse measurement at the wrist.
