1. A 23-year-old woman was diagnosed with systemic lupus erythematosus (SLE) at age 13 years when she presented with polyarticular joint swelling. On a regimen of methotrexate and hydroxychloroquine, her joint pain and swelling have been relatively well controlled. The patient’s fingers exhibit both boutonnière and swan-neck deformities, but she is able to make a normal closed fist. What will radiographs of the patient’s hands likely reveal?
  1. Bone fragmentation
  2. Carpal fusion
  3. Erosions in the proximal joints
  4. Marked subchondral cysts
  5. Normal joints

2. A 32-year-old woman with longstanding SLE presents with severe headache. Her blood pressure is 200/110 mm Hg, the cardiac examination is remarkable for an S4, and a new heart murmur is noted at the left sternal border. Her medical history includes 3 spontaneous abortions and multiple episodes of pleurisy, arthritis, and thrombocytopenia. Dipstick urinalysis is positive for protein and trace blood. Microscopic examination shows 3 to 5 erythrocytes per high power field and an occasional granular cast. Serum creatinine level is 4.0 mg/dL. What is a renal biopsy likely to show?

  1. Diffuse proliferative glomerulonephritis
  2. Focal segmental glomerulonephritis
  3. IgA deposits
  4. Mesangial deposits (seen by electron microscopy only)
  5. Thrombotic microangiopathy

3. A 20-year-old man with SLE presents to the emergency department with chest pain that started 10 days ago.

Blood pressure is 94/50 mm Hg and heart rate is 100 bpm. The heart sounds are quiet, and tubular breath sounds are heard at the left scapular border. There is 1+ peripheral edema. Chest radiograph shows a possible cardiomegaly. What is the next step in this patient’s management?

  1. Arterial blood gas

5. A 31-year-old man with a history of lupus nephritis in remission is seen in the office for routine follow-up. Medications include hydroxychloroquine and naproxen. Laboratory tests are performed, and the hemoglobin level is noted to have dropped to 9.0 mg/dL since the last testing 3 months ago. Platelet counts, leukocyte counts, and renal function are normal. The erythrocyte sedimentation rate is 45 mm/h. Other than being more tired than usual, the patient has no complaints. What will the evaluation of anemia most likely show?

  1. Cold agglutinins
