Final answer:
The correct answer is A. Gouty arthritis involves a sudden onset of severe pain, redness, and swelling typically at the big toe, knee, or ankle due to uric acid crystal deposits. The pain associated with gout is because of the build-up of these crystals, which leads to painful movement of the joints.
Step-by-step explanation:
Clinical Manifestations of Gouty Arthritis
Gouty arthritis is a type of inflammatory arthritis characterized by the deposition of uric acid crystals in the joints, leading to intense pain and inflammation. The correct answer to the question about the clinical manifestations of gouty arthritis is A. Sudden onset of severe joint pain, redness, swelling, warmth, and tenderness of the affected joint, and limited range of motion. This typically occurs at the big toe, knee, or ankle, and although the attack may be short-lived, lasting a few days, it can recur. Gouty arthritis differs from other forms of arthritis such as rheumatoid arthritis, which is symmetrical and affects the same joints on both sides of the body, and osteoarthritis, which has a gradual onset of joint pain and stiffness due to the breakdown of joint cartilage and bone.
To address the follow-up question regarding why gout results in pain: The correct choice is B. Uric acid crystals build up in the joints, resulting in painful body movements. These needle-like crystals cause intense pain and inflammation within the joint.
