ABIM Rheumatology Initial Certification Examination Practice Test

Rheumatology practice questions address inflammatory and degenerative joint disease, systemic autoimmune conditions, crystal arthritis, bone health, and musculoskeletal complications. The available cases include lupus nephritis, rheumatoid and psoriatic arthritis, systemic sclerosis, gout, axial spondyloarthritis, and osteoporosis. They ask you to interpret clinical findings and laboratory or imaging clues in context.

About the ABIM Rheumatology Initial Certification Examination Exam

The scenarios call for distinguishing overlapping presentations, such as inflammatory synovitis from osteoarthritis or an arthritis flare from septic arthritis. They also test how to use targeted investigations: synovial-fluid analysis for acute monoarthritis, kidney biopsy to characterize suspected lupus nephritis, and HLA-B27 as supportive rather than diagnostic evidence in axial spondyloarthritis. Other decisions include recognizing rheumatoid arthritis treatment goals, counseling about methotrexate and pregnancy, identifying skin involvement patterns in systemic sclerosis, and relating psoriatic arthritis to characteristic radiographic changes. Bone-health questions connect fragility fractures and fracture risk with pharmacologic treatment choices. Across these tasks, careful reading of the history, examination, serology, imaging, and safety constraints supports differential diagnosis and management reasoning.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A 55-year-old woman with systemic lupus erythematosus has rising serum creatinine, proteinuria, and red blood cell casts. Which test is most useful for defining the class and activity of suspected lupus nephritis?

  1. ARenal biopsy
  2. BSerum uric acid measurement
  3. CSchirmer test
  4. DPlain radiography of the hands
Show answerCorrect answer: A

Kidney biopsy classifies lupus nephritis and assesses activity and chronicity, information that guides prognosis and immunosuppressive treatment. Urinary findings and serologies raise concern, but do not reliably replace histologic assessment when biopsy is indicated.

Question 2

A patient with rheumatoid arthritis is starting methotrexate. Which counseling point is most important regarding pregnancy?

  1. AMethotrexate is safe throughout pregnancy if the dose is below 15 mg weekly
  2. BMethotrexate is contraindicated during pregnancy because of embryo-fetal toxicity
  3. CMethotrexate should be stopped only after the first trimester
  4. DMethotrexate is safe during pregnancy when taken with folic acid
Show answerCorrect answer: B

Methotrexate is an antifolate with established embryo-fetal toxicity and is contraindicated during pregnancy. Patients planning pregnancy should discuss discontinuation and alternative disease control with their clinicians; folic acid does not make methotrexate safe in pregnancy.

Question 3

A 46-year-old woman has Raynaud phenomenon, puffy fingers, and progressive skin thickening extending proximal to the elbows. Which systemic sclerosis subtype is most consistent with this extent of skin involvement?

  1. ALimited cutaneous systemic sclerosis
  2. BDiffuse cutaneous systemic sclerosis
  3. CMorphea
  4. DEosinophilic fasciitis
Show answerCorrect answer: B

Diffuse cutaneous systemic sclerosis involves skin thickening proximal to the elbows or knees, or on the trunk. Limited cutaneous disease is generally restricted to distal extremities and face.

Question 4

A 50-year-old woman has symmetric inflammatory polyarthritis, elevated inflammatory markers, and a high-titer anti-CCP antibody. Which additional finding is most characteristic of rheumatoid arthritis rather than osteoarthritis?

  1. AMarginal erosions at the metacarpophalangeal joints
  2. BOsteophytes at the distal interphalangeal joints
  3. CSubchondral sclerosis at the first carpometacarpal joint
  4. DHeberden nodes without synovitis
Show answerCorrect answer: A

Rheumatoid arthritis commonly causes marginal erosions, particularly at the metacarpophalangeal and proximal interphalangeal joints. Osteophytes and subchondral sclerosis are typical osteoarthritis features.

Question 5

A 49-year-old man with psoriasis has chronic inflammatory pain in several distal interphalangeal joints and nail pitting. Which radiographic finding is characteristic of psoriatic arthritis?

  1. ASymmetric uniform joint-space narrowing with marginal erosions and periarticular osteopenia
  2. BErosions with adjacent new bone formation, sometimes producing a pencil-in-cup appearance
  3. CChondrocalcinosis with predominant involvement of the triangular fibrocartilage
  4. DPeriarticular punched-out erosions with overhanging edges and preserved bone density
Show answerCorrect answer: B

Psoriatic arthritis can produce erosions together with new bone formation, including the classic pencil-in-cup deformity in advanced disease. The other findings are more characteristic of rheumatoid arthritis, calcium pyrophosphate deposition disease, and gout, respectively.

Question 6

A 29-year-old woman with newly diagnosed rheumatoid arthritis has active synovitis but is not pregnant and has no contraindication to disease-modifying therapy. Which strategy best reflects the general treatment goal?

  1. AUse analgesics alone until erosions appear
  2. BBegin disease-modifying therapy early and adjust treatment toward low disease activity or remission
  3. CReserve disease-modifying therapy for patients with extra-articular disease
  4. DUse intermittent glucocorticoids as the only long-term disease control
Show answerCorrect answer: B

Early disease-modifying antirheumatic drug treatment reduces ongoing inflammation and the risk of structural damage. Treat-to-target care involves regular assessment and adjustment of therapy to achieve remission or low disease activity, rather than relying on symptomatic medicines alone.

Question 7

A 46-year-old woman with longstanding rheumatoid arthritis has a sudden increase in pain and swelling in one knee. The joint is warm, and she is taking immunosuppressive therapy. Which diagnostic step is most important before attributing the symptoms to an inflammatory arthritis flare?

  1. AMeasure serum rheumatoid factor
  2. BPerform arthrocentesis for cell count, Gram stain, and culture
  3. CObtain a bone density scan
  4. DOrder MRI of both hands
Show answerCorrect answer: B

Acute monoarthritis in an immunosuppressed patient requires prompt evaluation for septic arthritis. Synovial fluid analysis, including Gram stain and culture, is essential; crystals, if present, do not exclude concurrent infection.

How to use this practice test

Access is free. The question bank contains 50 published practice questions; each session presents up to 20 random questions. Submit a session to see your results, then use missed or uncertain items to identify topics for targeted review, such as crystal identification, immunosuppressant safety, or inflammatory joint patterns.

Preparation tips

  • For acute monoarthritis, practice separating inflammatory flares from infection and identify when joint aspiration with cell count, culture, and crystal analysis is needed.
  • Compare rheumatoid arthritis, psoriatic arthritis, osteoarthritis, and axial spondyloarthritis using joint distribution, extra-articular features, serology, and imaging clues.
  • Review systemic lupus erythematosus kidney findings and how biopsy results define lupus nephritis class and activity.
  • Connect disease-modifying therapy choices with safety counseling, including methotrexate exposure during pregnancy and appropriate treatment goals in active rheumatoid arthritis.
  • Revisit osteoporosis treatment decisions in the context of fragility fractures and elevated fracture risk.
