Answer to Question 1

B
The stomach is the site where protein digestion begins. Acid is secreted in the stomach to en-hance this process. Because the acids can damage the stomach lining, the stomach secretes a thick, gel-like mucus to protect it. Neither the esophagus nor the duodenum has this protection. Stomach contents that reflux up into the esophagus are highly acidic and cause inflammatory damage with ulcer formation to the lining.

Answer to Question 2

B
NRTIs increase the risk for lactic acidosis in pregnant women. This problem is not a common occurrence for other patients. Lactic acidosis is the buildup of lactic acid in muscle and other tissues when not enough oxygen is present to allow metabolism to occur normally. Signs and symptoms of lactic acidosis are muscle aches, tiredness and difficulty remaining awake, abdo-minal pain, hypotension, and a slow, irregular heartbeat.
