Rheumatology Certification Examination Study Guide

Apply it

If fractures occur in 12 of 200 controls and 6 of 200 treated participants over one year, relative risk is 0.5, absolute reduction is 3 percentage points, and NNT is 34.

Apply it

A cohort associates biologic treatment with hospitalization, but recipients have much greater baseline disease activity. Examine severity-adjusted comparisons before concluding that the medication caused the excess admissions.

Apply it

Connect these broad signaling effects with infection assessment and blood-count monitoring. Before treatment, review tuberculosis, viral hepatitis, blood counts, hepatic function, and immunizations as specified in the label.

Apply it

A patient has nausea after weekly oral methotrexate but improving synovitis and acceptable monitoring results. Discuss folate adjustment, split administration, or subcutaneous treatment before declaring the medication unusable.

Apply it

Three documented flares in one year and a palpable tophus support long-term urate reduction. Explain that treating attacks alone leaves the underlying crystal burden unaddressed.

Apply it

After an early flare on low-dose allopurinol, treat the inflammation, check prophylaxis, and continue monitored titration rather than abandoning urate lowering solely because symptoms appeared.

Apply it

Weakly positively birefringent rhomboid crystals in an inflamed knee support CPP crystal arthritis. Address inflammation and relevant associated disorders rather than prescribing allopurinol for calcium deposition.

Apply it

For a stable patient with fever and a swollen knee, urgently obtain joint fluid and appropriate blood cultures before treatment. If shock develops, begin sepsis management immediately.

Apply it

Months of unexplained knee swelling in a person with relevant exposure history warrant targeted mycobacterial testing and consideration of synovial biopsy before assuming sterile inflammatory arthritis.

Apply it

An immunosuppressed patient with acute knee pain, crystals, 18,000 leukocytes/µL, and a negative Gram stain still needs microbiologic assessment when infection remains clinically plausible.

Apply it

Persistent effusion after antibiotics given before aspiration warrants discussion with microbiology about prolonged incubation and molecular testing, alongside reassessment of drainage and alternative diagnoses.

Apply it

A postmenopausal patient's T-score of −2.6 meets densitometric osteoporosis classification. A younger man's Z-score of −2.3 instead prompts contextual assessment for fractures and secondary contributors.

Apply it

Low density accompanied by diffuse bone pain, proximal weakness, and a phosphate or vitamin D disturbance warrants investigation of mineralization before assuming uncomplicated primary osteoporosis.

Apply it

A postmenopausal patient with primary osteoporosis and no contraindication can begin a bisphosphonate. Multiple fractures or other very-high-risk features warrant consideration of a bone-forming treatment sequence.

Apply it

A patient has stopped walking because knee discomfort is interpreted as damage. Develop a tolerable strengthening and activity plan, adapting intensity while tracking meaningful changes in daily function.

Apply it

For localized knee osteoarthritis and a preference to limit systemic exposure, discuss a topical NSAID alongside exercise, while explaining why the same approach may not suit deep hip pain.

Apply it

A patient wants to remain employed in a standing role. Combine accessible nutritional support, strengthening, activity adaptation, and analgesia, measuring success through work tolerance and everyday function.

Apply it

Three involved small joints, high-positive ACPA, normal inflammatory markers, and eight weeks of symptoms yield 2 + 3 + 0 + 1 = 6.

Apply it

Persistent swelling of multiple small joints and major functional limitation support methotrexate when appropriate, with explicit monitoring and follow-up rather than analgesia alone.

Apply it

For confirmed low-activity RA with limited functional impact, discuss hydroxychloroquine while considering prognostic findings, preferences, and a plan to reassess whether the initial strategy controls disease.

Apply it

Partial improvement with persistent swollen joints warrants adherence review, optimization, and possible escalation. Pain without corresponding inflammatory findings instead requires assessment of other contributors.

Apply it

For active RA despite methotrexate in class III heart failure, consider an appropriate non-TNF biologic. Verify previous TNF-blocker exposure before considering a JAK inhibitor.

Apply it

A core-antibody-positive, surface-antigen-negative patient starting rituximab needs a prophylaxis plan rather than reassurance based only on the negative surface antigen.

Apply it

Active RA four months after hospitalization for pneumonia warrants discussion of conventional combination therapy and infection risk rather than reflexive biologic escalation or prolonged higher-dose prednisone.

Apply it

After nine months of sustained low activity, discuss monitored gradual reduction if desired, retain effective disease-modifying treatment, and arrange reassessment for recurrence.

Apply it

Inflammatory finger symptoms with a diffusely swollen toe, nail pitting, and Achilles insertion pain warrant assessment of peripheral, digital, entheseal, and possible axial disease.

Apply it

Persistent inflammatory spinal symptoms without peripheral synovitis despite appropriate NSAID trials warrant reassessment of activity and axial-directed treatment eligibility rather than methotrexate solely for spinal inflammation.

Apply it

Verify treatment trials, activity scores, and objective findings, excluding alternative reasons for elevated CRP or MRI abnormalities. Combine results with rheumatologist judgment and patient preferences.

Apply it

For axial disease requiring a biologic with repeated anterior uveitis, favor an appropriate monoclonal TNF antibody when otherwise suitable and coordinate eye care.

Apply it

Frequent cold-triggered attacks despite protective measures support oral vasodilator treatment if blood pressure permits. Examine persistent pain and ulceration separately for more severe vascular disease.

Apply it

A major blood-pressure increase with rapidly worsening kidney function in systemic sclerosis requires urgent assessment and ACE-inhibitor-based treatment when renal crisis is supported.

Apply it

Declining lung function with progressive interstitial abnormalities warrants multidisciplinary review of immune-directed and antifibrotic options, while checking for concurrent cardiac or pulmonary vascular disease.

Apply it

After specialist confirmation of pulmonary arterial hypertension, consider the recommended combination rather than treating an echocardiographic estimate alone or assuming ILD treatment addresses vascular disease.

Apply it

Violaceous eyelid discoloration and extensor finger-joint papules accompanying difficulty rising from a chair support dermatomyositis assessment. Confirm reproducible proximal weakness rather than relying on perceived fatigue.

Apply it

Persistent Gottron-type papules and heliotrope discoloration with normal strength and enzymes warrant appropriate dermatologic evaluation and consideration of biopsy rather than automatic dismissal.

Apply it

During pregnancy, antibody positivity without APS supports conditional aspirin 81–100 mg daily, begun before 16 weeks, and a conditional recommendation against routinely adding prophylactic heparin. Obstetric APS without thrombosis warrants aspirin plus prophylactic heparin; thrombotic APS warrants aspirin plus therapeutic heparin, both strongly recommended. Persistent antibodies with no thrombosis and only two early miscarriages do not meet this framework’s obstetric threshold. Exceptional risks, including triple antibody positivity, may justify individualized heparin use.

Apply it

Anti-SSA positivity plus Schirmer testing of 3 mm/5 minutes totals 4 in an eligible patient without exclusions. Three low-weight tests alone total only 3.

Apply it

For a child with active polyarticular-course JIA after TNF-blocker intolerance, verify age, weight, previous treatment, infection screening, laboratory eligibility, and vaccinations before choosing the regimen.

Apply it

Persistent unilateral gland enlargement with unexplained weight loss requires evaluation for a complication, including lymphoma, rather than simply increasing dry-mouth treatment.

Apply it

Persistent urine protein-to-creatinine ratio of 0.8 g/g with microscopic hematuria warrants nephritis assessment and biopsy consideration even when serum creatinine remains normal.

Apply it

Use initial intravenous glucocorticoid pulses followed by reduced-dose oral treatment and taper toward at most 5 mg/day prednisone by six months. Continue hydroxychloroquine unless contraindicated. Quantify proteinuria at least every three months before complete response and every three to six months during sustained remission.

Apply it

For well-controlled SLE when pregnancy is confirmed, continue hydroxychloroquine if appropriate and review the remaining regimen individually rather than stopping all rheumatologic treatment.

Apply it

An anti-Ro-positive patient with quiet SLE and a previous infant with neonatal lupus needs coordinated surveillance based on antibody and pregnancy history despite maternal clinical remission.

Apply it

For SLE with qualifying obstetric morbidity and persistent antibodies but no thrombosis, select the obstetric APS pathway rather than the therapeutic intensity used after venous or arterial thrombosis.

Apply it

Similar active and passive external-rotation loss with months of stiffness and no explanatory radiographic arthritis supports adhesive capsulitis rather than isolated muscle weakness.

Apply it

For controlled RA with diffuse aching and poor sleep but no new swollen joints, assess noninflammatory contributors. A separately restricted shoulder still needs its own local examination.

Apply it

Nocturnal thumb, index, and middle-finger tingling relieved by shaking the hand supports carpal tunnel assessment, while examination checks severity and competing neurologic explanations.

Apply it

Constant numbness, declining pinch function, and visible thenar wasting despite previous splint treatment require reassessment and timely referral rather than repeated renewal of the same conservative plan.

Apply it

For MCP symptoms with elevated ferritin, obtain a broader iron assessment. Persistent hand pain after successful iron depletion needs separate joint care rather than automatic intensification of phlebotomy.

Apply it

Diffuse aching with new cold intolerance, weight gain, dry skin, and bradycardia supports thyroid testing while examining for true synovitis and other explanations.

Apply it

Nonnecrotizing granulomas in a patient with pulmonary abnormalities require clinical integration and assessment of infectious or exposure-related alternatives before accepting sarcoidosis and prescribing immunosuppression.

Apply it

Low 25-hydroxyvitamin D with elevated calcium in sarcoidosis requires assessment of the calcium disturbance and active metabolite before recommending replacement.

Apply it

An older adult with persistent back pain, unexplained anemia, renal impairment, and hypercalcemia needs plasma-cell evaluation rather than automatic attribution to degenerative disease or osteoporosis.

Apply it

New temporal headache, jaw claudication, and transient monocular visual loss in an older adult constitute an urgent vision-threatening pattern even after the visual episode resolves.

Apply it

After treatment begins for strongly suspected giant cell arteritis, arrange an adequate-length specimen promptly rather than cancelling biopsy or withholding necessary treatment to preserve untreated histology.

Apply it

New arterial abnormalities despite clinical well-being and normal inflammatory markers require reassessment of activity and vascular consequences rather than dismissal.

Apply it

Rapidly progressive glomerulonephritis attributed to GPA requires severe-disease induction rather than methotrexate selected merely because it treats other inflammatory manifestations.

Apply it

A clinically well patient with increased PR3-ANCA but stable kidney function and urine findings needs reassessment and appropriate monitoring rather than automatic induction therapy.

Apply it

After teaching a weekly medication schedule, ask which day the patient will take it and how the supply will be organized. Correct errors before completing the visit.

Apply it

When an abscess overlies the usual knee entry site, choose an alternative route with appropriate expertise or imaging guidance instead of traversing infected tissue.
