A nerve block is classified as which type of medical procedure?

A nerve block is classified as an injection-based medical procedure where local anesthetics or other medications are injected near specific nerves to block pain in a particular area of the body. This technique is often used for pain management during surgeries, after certain surgical procedures, or for chronic pain conditions. By targeting the nerve pathways responsible for transmitting pain signals, a nerve block can provide significant relief and allow patients to recover more comfortably.

Other categories like meditation, surgery, and exercise do not accurately describe a nerve block. Meditation is a mental practice for relaxation and stress relief, surgery involves invasive procedures that alter body structures, and exercise refers to physical activity aimed at improving fitness or health. Thus, injection is the most appropriate classification for a nerve block.
