An 8-year-old child comes to the physician's office complaining of swelling and pain in the knees. His mother says, "The swelling occurred for no reason, and it keeps getting worse." The initial diagnosis is Lyme disease. When talking to the mother and child, questions related to which of the following would be important to include in the initial history?

1. A

   A decreased urinary output and flank pain

2. B

   A fever of over 103°F occurring over the last 2-3 weeks

3. C

   Rashes covering the palms of the hands and the soles of the feet

4. D

   Headaches, malaise, or sore throat

Explanation

Listen in Hindi

• The child's presenting symptoms of knee swelling and pain are characteristic of Stage 3 (Late Persistent) Lyme disease, specifically Lyme arthritis.
• To confirm a diagnosis of a progressive disease like Lyme, it is crucial for the nurse to ask about symptoms of earlier stages that would have preceded the current presentation.
• Headaches, malaise, and sore throat are classic systemic symptoms of Stage 1 (Early Localized) and Stage 2 (Early Disseminated) Lyme disease.
• Identifying a history of these early symptoms helps establish the timeline and supports the diagnosis of Lyme disease as the cause of the arthritis.

Why Other Options Were Wrong

• Option A: Decreased urinary output and flank pain are signs of renal or urinary tract dysfunction, which are not associated with the typical clinical progression of Lyme disease.
• Option B: While a low-grade fever can occur in early Lyme disease, a persistent high fever (above 103°F or 39.4°C) is not characteristic. Furthermore, Lyme arthritis typically develops months after the initial infection, not just 2-3 weeks.
• Option C: A rash on the palms and soles is a hallmark sign of other diseases, most notably Rocky Mountain spotted fever and secondary syphilis. The characteristic rash of Lyme disease is erythema migrans, an expanding 'bull's-eye' lesion.

Clinical Relevance

• Nursing practice connection: Use the key finding related to Clinical presentation and diagnostic history for Lyme disease to guide bedside assessment, documentation, and the next nursing action.
• A thorough patient history is one of the most powerful diagnostic tools a nurse has, especially for diseases like Lyme that evolve over time. Failing to ask about previous symptoms can lead to a delayed or missed diagnosis.
• Early diagnosis and treatment of Lyme disease with antibiotics can prevent the progression to debilitating late-stage complications like arthritis, carditis, and neurological problems.
• Patient education on tick prevention is a key nursing role. This includes teaching about protective clothing, use of DEET-containing repellents, and performing thorough body checks after potential exposure.

How to Approach the Question

• Step 1: Identify the key information in the clinical scenario: an 8-year-old child with knee swelling/pain and a suspected diagnosis of Lyme disease.
• Step 2: Recall the pathophysiology of Lyme disease. Recognize that it is a multi-stage illness and that joint involvement (arthritis) is a feature of the late stage (Stage 3).
• Step 3: Understand the question is asking what historical information is important. This implies you need to look for symptoms of the earlier stages that would have occurred before the current late-stage symptoms.
• Step 4: Evaluate each option. Option D (Headaches, malaise, sore throat) lists common symptoms of early-stage Lyme disease.
• Step 5: Eliminate the other options by identifying them as symptoms of different diseases (Option C - Rocky Mountain spotted fever) or as inconsistent with the typical presentation of Lyme disease (Options A and B).

Concept Tested & Keywords

• Concept Tested: Clinical presentation and diagnostic history for Lyme disease.
• Stem keywords: 8-year-old child, swelling and pain in the knees, Lyme disease, initial history
• Lead-in keywords: important to include
• Clinical cues: Knee swelling and pain in a child suggests oligoarticular arthritis, a hallmark of late-stage Lyme disease.
