Grade I Sprain/Strain

• A. some pain, minimal loss of function, no abnormal function, & mild point tenderness
• B. moderate pain and swelling, minimal instability of the joint, minimal to moderate tearing of the ligament, decreased ROM
• C. extremely painful, inevitable loss of function, swelling
• D. slight swelling with no loss of function

Answer: (A)

Grade I sprain/strain is mild tissue damage with preserved function. You’ll usually have some pain after injury and mild point tenderness, with minimal swelling and little to no loss of function or joint instability. This fits the description of mild pain with only minimal functional impairment and mild tenderness, which is why it’s the best match. The other options describe more severe scenarios: moderate pain with swelling and some instability (Grade II), extreme pain with significant swelling and major loss of function (Grade III), or slight swelling with no loss of function (which doesn’t align with a sprain/strain presentation).
