Answer to Question 1

ANS: A
Gonorrhea is a sexually transmitted infection that often involves reactive arthritis. The polyarthritis is often migratory and affects lower extremities as well as the hands. In addition to the arthritis, the syndrome usually includes a nonpruritic dermatitis and tenosynovitis. Generalized muscle aches and fever are also common.

Answer to Question 2

ANS: B
Sarcoidosis is an inflammatory disorder in which patients develop granulomas and a wide range of symptoms, including arthritis. It is most commonly diagnosed in persons between ages 20 and 40. Arthralgias occur in approximately 3 of patients with sarcoidosis, and the most commonly affected joints include the ankles, feet, and hands. The patient may complain of constitutional symptoms, including fatigue, fever, and altered appetite. Respiratory symptoms, including cough, wheezing, and shortness of breath, are primary symptoms. On chest x-ray, hilar lymphadenopathy and pulmonary granulomas are key diagnostic signs.
