Answer to Question 1

B
The stomach secretes a thick gel-like mucus that coats and protects it from contact with stomach acids. Acid production is usually balanced by mucous secretion. When acid production exceeds mucous production, the risk for tissue damage and ulcer formation increases.

Answer to Question 2

D
Peripheral neuropathy with loss of sensation in the extremities is a common and expected side effect of therapy. Drug therapy is not stopped for this effect. The patient needs to implement precautions to prevent injury from not having full sensation for touch, temperature, and pressure.
