Correct Answer is A
Explanation
A. Ensure that the stool specimen does not contain urine: Fecal occult blood tests are designed to detect blood in the stool, so it's important to ensure that the specimen
collected is not contaminated with urine, which could yield a false-positive result.
B. Wear sterile gloves when handling the stool specimen: Sterile gloves are not typically required for handling stool specimens for fecal occult blood testing. Standard
precautions, including hand hygiene and wearing non-sterile gloves, are sufficient.
C. Repeat the test three times using the same stool specimen: The test is typically
performed once on a fresh stool specimen, and repeating the test with the same specimen is not recommended.
D. Have the client defecate into a bedpan that contains a small amount of water: Fecal occult blood testing requires a small sample of stool collected from a bowel movement. Using a bedpan with water may dilute the stool and affect the accuracy of the test.
