Answer to Question 1

B
ESR is a very nonspecific but sensitive indication of inflammation. RF is positive in 75 to 85 of patients with rheumatoid arthritis (RA). ANAs are elevated in approximately 20 of patients with RA. These tests help confirm the diagnosis of RA. Once the diagnosis is more likely, referral to a specialist is warranted. Drug therapy is not begun until the diagnosis is confirmed. X-rays are usually the earliest way to detect changes but are not diagnostic in the early stages of the disease.

Answer to Question 2

C
Bismuth reduces symptoms through antidiarrheal and antibacterial properties and can decrease nausea and vomiting. Opioid antidiarrheals should be given after the cause of infectious diarrhea is treated; these can actually prolong symptoms because they slow transit of the causative organisms through the gut. Attapulgite can be used because it binds bacteria and toxins in the gastrointestinal tract, but bismuth is a better choice in this case because it helps to treat nausea. The patient is drinking Gatorade and is getting electrolyte replacement.
