Final answer:
b. Tendinitis is an example of a repetitive strain injury, caused by overuse of a tendon through repetitive motions and often requires treatment with PRICE and NSAIDs.
Step-by-step explanation:
An example of a repetitive strain injury is tendinitis. Tendinitis is the inflammation of a tendon and typically occurs when a tendon is overextended or exerted too much without sufficient rest. This type of injury is common among individuals whose jobs or hobbies require repetitive motions, which can lead to microtrauma in the affected tendons. Treatment often involves the steps represented by the acronym PRICE (protection, rest, ice, compression, and elevation), and in some cases, medications for inflammation and pain like NSAIDs may be utilized. Severe cases of tendinitis that result in a torn tendon might require surgical repair, which is a slow-healing process due to the limited blood supply in tendons.
