A 6-year-old boy is presented to a pediatric clinic by his mother with complaints of fever, malaise, and cough for the past 2 days. He frequently complains of a sore throat and has difficulty eating solid foods. The mother mentions that, initially, the boy’s fever was low-grade and intermittent but later became high grade and continuous. The boy was born at 39 weeks gestation via spontaneous vaginal delivery. He is up to date on all vaccines and is meeting all developmental milestones. The past medical history is noncontributory. The boy takes a multivitamin every day. The mother reports that he does well in school and is helpful around the house. The boy’s vital signs include blood pressure 110/65 mm Hg, heart rate 110/min, respiratory rate 32/min, and temperature 38.3°C (101.0°F). On physical examination, the boy appears uncomfortable and has difficulty breathing. His heart is mildly tachycardic with a regular rhythm and his lungs are clear to auscultation bilaterally.

A 55-year-old man presents after an episode of severe left ankle pain. The pain has resolved, but he decided to come in for evaluation as he has had pain like this before. He says he has experienced similar episodes of intense pain in the same ankle and his left knee in the past, which he associates with eating copious amounts of fatty food during parties. On one occasion the pain was so excruciating, he went to the emergency room, where an arthrocentesis was performed, revealing needle-shaped negatively birefringent crystals and a high neutrophil count in the synovial fluid. His past medical history is relevant for essential hypertension which is managed with hydrochlorothiazide 20 mg/day. His vital signs are stable, and his body temperature is 36.5°C (97.7°F). Physical examination shows a minimally tender left ankle with full range of motion. Which of the following is the most appropriate long-term treatment in this patient?
A 42-year-old woman comes to her primary care physician because of an irritating sensation in her nose. She noticed recently that there seems to be a lump in her nose.

He says he took acetaminophen and ibuprofen for the pain as before but, unlike the last time, it hasn't helped. The patient denies any recent history of trauma or fever. No significant past medical history and no other current medications. Family history is significant for his mother who has type 2 diabetes mellitus and his father who has hypertension. The patient reports regular drinking and the occasional binge on the weekends but denies any smoking history or recreational drug use. The vital signs include pulse 86/min, respiratory rate 14/min, and blood pressure 130/80 mm Hg. On physical examination, the patient is slightly overweight and in obvious distress. The 1st metatarsophalangeal joint of the left foot is erythematous, severely tender to touch, and swollen. No obvious deformity is seen. The remainder of the examination is unremarkable. Joint arthrocentesis of the 1st left metatarsophalangeal joint reveals sodium urate crystals. Which of the following drugs would be the next best therapeutic step in this patient?
