He has had 2 episodes of nonstreptococcal pharyngitis. You suspect that he may have systemic lupus erythematosus (SLE), and you are considering ordering an antinuclear antibody (ANA) test. Which of the following is the most accurate characteristic of the ANA test and its role in establishing the diagnosis of SLE?
A negative ANA test result helps rule out SLE.
A positive ANA test result needs no follow-up testing.
Has a high positive predictive value.
Is highly specific.
Is positive in approximately 50% of the healthy population
A 15-year-old adolescent girl, who is followed up in your clinic, has recently been diagnosed as having SLE with mild renal involvement based on clinical criteria and a positive ANA test result. She has no mucocutaneous features. Her complete blood cell count is normal except for mild anemia. In addition to nonsteroidal anti-inflammatory drugs for managing the fevers and arthritis, which of the following is the most appropriate initial treatment regimen in this patient?
Glucocorticoids.
Hydroxychloroquine.
Intravenous immunoglobulin.
Plasmapheresis.
Rituximab
A 13 years old child with juvenile idiopathic inflammatory myopathies, particularly juvenile dermatomyositis underwent a full evaluation. Serum levels of skeletal muscle enzymes, including creatine kinase, aspartate aminotransferase, lactate dehydrogenase, and aldolase, were elevated. Physical examination was significant for weakness in his upper and lower extremities and difficulty combing his hair. Electromyographic and magnetic resonance imaging findings were consistent with juvenile dermatomyositis. Which of the following is the most appropriate next step in initial management in this patient?
Cyclophosphamide.
Intravenous immunoglobulin.
Nonsteroidal anti-inflammatory drugs.
Prednisone.
Tacrolimus

Dysphagia.
Generalized lymphadenopathy.
Headaches.
Hepatosplenomegaly.

On physical examination, the patient is observed to have an asymmetrical gait and pain with internal rotation of the right hip. Which of the following is the next best step in management?
Biopsy of the femoral head.
Broad spectrum antibiotic therapy.
Nonsteroidal anti-inflammatory medications and physical therapy.
