Answer to Question 1

Ans: D
Occult blood in the stool is blood that is hidden in the specimen or cannot be seen on gross examination. It can be detected with simple screening tests, such as a Hematest.

Answer to Question 2

Ans: A
Nurses are commonly involved in scheduling diagnostic studies when a client is to undergo multiple studies. They should follow a logical sequence when more than one test is required for accurate diagnosis; that is, fecal occult blood tests to detect gastrointestinal bleeding; barium studies to visualize gastrointestinal structures and reveal any inflammation, ulcers, tumors, strictures, or other lesions; and endoscopic examinations to visualize an abnormality, locate a source of bleeding, and if necessary, provide biopsy tissue samples.
