📒 The 1-minute cheat sheet
⚠️ Cause
Untreated group A strep
Autoimmune rxn 2-3 wks later
🩺 Signs
JONES: Joints, carditis
Nodules, erythema, chorea
Fever, ↑ASO titer, ↑ESR
📌 Risk
Carditis → valve damage
Mitral stenosis later
✅ Do
Penicillin → treat + prophylaxis
Treat strep promptly = prevent
📚 Rheumatic Fever — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
Rheumatic fever is an inflammatory autoimmune reaction that follows an untreated group A beta-hemolytic streptococcal infection, usually strep throat. It can damage the heart, joints, skin, and nervous system, and is the leading cause of acquired valve disease (especially mitral stenosis). Prompt antibiotic treatment of strep throat prevents it.
🔑
Key points
Understand these first
Develops 2-3 weeks after an untreated group A streptococcal pharyngitis.
Carditis is the most serious manifestation and can permanently scar heart valves.
Major Jones criteria include carditis, migratory polyarthritis, chorea, subcutaneous nodules, and erythema marginatum.
Diagnosis is supported by elevated ASO titer and evidence of recent strep infection.
Long-term prophylactic penicillin prevents recurrence and further valve damage.
Treating strep throat with full-course antibiotics prevents rheumatic fever.
✅
Nursing priorities
What to do, in order
Administer prescribed antibiotics (penicillin) to eradicate streptococcus and complete the full course.
Provide anti-inflammatory therapy (aspirin/NSAIDs) and monitor for relief of joint inflammation.
Assess cardiac status: heart sounds, murmurs, rhythm, and signs of heart failure.
Promote rest during the acute inflammatory and carditis phase.
Educate on lifelong prophylactic antibiotics to prevent recurrence.
🚩
Red flags — report now
Escalate immediately
New murmur, tachycardia, chest pain, or signs of heart failure indicate carditis — report promptly.
Elevated ESR (normal 0-20 mm/hr) and CRP (normal under 1 mg/dL) reflect active inflammation
Positive throat culture or rapid strep test for group A strep
🗣️
Patient teaching
What patients must know
Always complete the full course of antibiotics for strep throat to prevent rheumatic fever.
Take prophylactic antibiotics long term as prescribed to prevent recurrence.
Report sore throats promptly for evaluation and treatment.
Inform providers of rheumatic fever history before dental/invasive procedures due to valve risk.
❓ Rheumatic Fever: NCLEX FAQs
What are the priority nursing interventions for Rheumatic Fever?
Administer prescribed antibiotics (penicillin) to eradicate streptococcus and complete the full course. Provide anti-inflammatory therapy (aspirin/NSAIDs) and monitor for relief of joint inflammation. Assess cardiac status: heart sounds, murmurs, rhythm, and signs of heart failure. Promote rest during the acute inflammatory and carditis phase.
What are the warning signs of Rheumatic Fever a nurse must report?
New murmur, tachycardia, chest pain, or signs of heart failure indicate carditis — report promptly. Sudden involuntary jerky movements (Sydenham chorea) require evaluation. Recurrent sore throats untreated risk repeat episodes and cumulative valve damage.
What do I need to know about Rheumatic Fever for the NCLEX?
Develops 2-3 weeks after an untreated group A streptococcal pharyngitis. Carditis is the most serious manifestation and can permanently scar heart valves. Major Jones criteria include carditis, migratory polyarthritis, chorea, subcutaneous nodules, and erythema marginatum. Diagnosis is supported by elevated ASO titer and evidence of recent strep infection.
What patient teaching is important for Rheumatic Fever?
Always complete the full course of antibiotics for strep throat to prevent rheumatic fever. Take prophylactic antibiotics long term as prescribed to prevent recurrence. Report sore throats promptly for evaluation and treatment. Inform providers of rheumatic fever history before dental/invasive procedures due to valve risk.
