Which of the following is not a component of Jones criteria for diagnosing acute rheumatic fever?
**Core Concept**
The Jones criteria are a set of clinical and laboratory criteria used to diagnose acute rheumatic fever (ARF), a complication of untreated or inadequately treated group A beta-hemolytic streptococcal (GABHS) pharyngitis. The Jones criteria help differentiate ARF from other post-streptococcal illnesses.
**Why the Correct Answer is Right**
The Jones criteria for major criteria include carditis, polyarthritis, chorea, erythema marginatum, and subcutaneous nodules. For minor criteria, they include clinical (fever, arthralgia) and laboratory (elevated erythrocyte sedimentation rate, elevated C-reactive protein) manifestations. The correct answer is not a component of the Jones criteria.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not a component of the Jones criteria. However, it could be considered a symptom of ARF, such as fever.
**Option B:** This option is incorrect because it is a minor criterion for the Jones criteria, specifically a laboratory manifestation.
**Option C:** This option is incorrect because it is a major criterion for the Jones criteria, specifically a clinical manifestation.
**Clinical Pearl / High-Yield Fact**
To remember the Jones criteria, use the mnemonic "CARDINAL": Carditis, Arthralgia, Rheumatic fever, Dermatitis, Inflammation, Nodules, and Laboratory abnormalities.
**Correct Answer:** D
