Answer to Question 1

C
Specimens will be positive if contaminated by menstrual blood or hemorrhoidal blood or povidone-iodine. A single positive test result does not confirm bleeding or indicate colorectal cancer. Diets rich in meats; green, leafy vegetables; poultry; and fish may produce false-positive results. Obtain a second fecal specimen from a different portion of the stool.

Answer to Question 2

C
A single positive test result does not confirm bleeding or indicate colorectal cancer. For confirmed positive results, the test must be repeated at least 3 times while the patient is on a meat-free, high-residue diet. More in-depth diagnosis is needed with a positive result.
