One of the major warning signals for arthritis is which of the following?

Arthritis is a condition characterized by inflammation of the joints, and its warning signals typically include symptoms such as joint pain, stiffness, swelling, and reduced range of motion. The correct answer reflects that none of the listed symptoms—redness in the eyes, dry mouth, or pus—are directly major warning signals of arthritis.

Redness in the eyes may pertain to other health issues, such as eye infections or allergies, while dry mouth could be associated with conditions like Sjögren’s syndrome, which can occur alongside autoimmune diseases but is not a direct indicator of arthritis itself. The presence of pus usually indicates an infection, which while relevant in a clinical setting, does not align with the classic symptoms of arthritis.

Understanding the major warning signals of arthritis focuses instead on joint-specific concerns, making it important to recognize that the evaluation of symptoms should be directed towards those that reflect inflammation or joint issues.
