Verified step by step guidance

1. Understand the concept of acute inflammation: Acute inflammation is a rapid response to injury or infection, characterized by redness, swelling, heat, and pain, typically lasting for a short duration.
2. Identify the characteristics of chronic inflammation: Chronic inflammation is a prolonged inflammatory response that can last for months or years, often associated with autoimmune diseases like rheumatoid arthritis.
3. Analyze each scenario: Determine whether each scenario involves a short-term inflammatory response (acute) or a long-term condition (chronic).
4. Scenario 1: Rheumatoid arthritis is a chronic inflammatory disease, not acute, as it involves long-term joint degradation.
5. Compare the other scenarios: Each involves a short-term inflammatory response, such as swelling or pain, typical of acute inflammation.
