검증된 단계별 안내1
Understand the concept of pulse palpation: Pulse palpation involves feeling the rhythmic expansion of an artery as blood is pumped through it by the heart. This is typically done at locations where arteries are close to the skin and over a bone.
Identify the anatomical location of the wrist: The wrist is located at the distal end of the forearm, where the radius and ulna bones meet the carpal bones.
Review the major arteries in the arm: The radial artery runs along the lateral side of the forearm (thumb side) and is superficial near the wrist, making it easily accessible for pulse palpation. The brachial artery is located higher up in the arm, near the elbow. The carotid artery is in the neck, and the femoral artery is in the thigh, neither of which are relevant to the wrist.
Determine why the radial artery is the most commonly used: The radial artery is superficial and easy to locate at the wrist, specifically at the radial side of the wrist near the base of the thumb. This makes it the preferred artery for pulse palpation in this region.
Conclude that the radial artery is the correct answer based on its anatomical location and accessibility for pulse palpation at the wrist.
