单项选择题
A client with a long history of ulcerative colitis takes sulfasalazine (Azulfidine) to control the condition. The nurse would anticipate the client to have which nutritional deficit that can occur as a result of taking this drug（）
A. Colbalamin.
B. Folic acid.
C. Niacin.
D. Iron.
答案
参考答案：B
解析：
Clients who take sulfasalazine are susceptible to developing impaired folic acid absorption. Common clinical manifestations of a folic acid deficiency are gastrointestinal disturbances such as anorexia, nausea, vomiting, and a smooth, beefy red tongue. The client should be encouraged to eat food high in folic acid such as green leafy vegetables, meat, fish, legumes, and whole grains.
