Answer to Question 1

ANS: B
AFP can help diagnose and guide the treatment of liver cancer (hepatocellular carcinoma). CA-125 is the standard tumor marker used to follow women during or after treatment for epithelial ovarian cancer (the most common type of ovarian cancer) as well as fallopian tube cancer and primary peritoneal cancer. Serum beta HCG is a pregnancy marker. CEA is not used to diagnose or screen for colorectal cancer, but it's the preferred tumor marker to help predict outlook in patients with colorectal cancer. The higher the CEA level at the time colorectal cancer is detected, the more likely it is that the cancer is advanced.

Answer to Question 2

ANS: A
Upper GI hemorrhage may result from a tear at the gastroesophageal junction, known as a Mallory-Weiss tear. A patient may develop more than one tear. These tears are most common in alcoholic or bulimic patients following repeated episodes of vomiting or severe retching. If a laceration/tear of the mucosa causes GI bleeding, the patient may demonstrate alterations in hemodynamic status.
