Final answer:
The most common site for capillary puncture in adults is the radial artery in the wrist, among other accessible pulse points like the carotid artery, and can also be measured with electronic devices.
Step-by-step explanation:
Capillary puncture in adults is commonly performed at the radial artery, which is located at the wrist.
However, there are multiple pulse points where blood can be drawn, and they include the common carotid artery in the neck, temporal and facial arteries in the head, brachial arteries in the upper arm, femoral arteries in the thigh, popliteal arteries behind the knees, posterior tibial arteries near the medial tarsal regions, and dorsalis pedis arteries in the feet.
These sites are commonly used because the artery runs close to the body surface, which makes it easier to palpate the pulse manually.
Additionally, several commercial electronic devices are also available to measure pulse.
